Price of sewage treatment equipment for small health clinic
The design of health sewage treatment equipment is based on the secondary biological contact oxidation treatment process used by this device. Its treatment effect exceeds that of the full mixed biological oxidation tank, and its adaptability to water quality is high, ensuring the stability of water treatment. The equipment uses a new type of elastic solid filler with good effect in the tank, which has a good function of removing substances in the agricultural production system in the sewage. After oxidation treatment, the equipment produces less sludge, which only needs to be discharged once every 90 days. In order to avoid the phenomenon of breeding and spreading of release bacteria, high-level disinfection treatment must be carried out for water quality. At present, many disinfection processes are used: ultraviolet disinfection, chlorine dioxide disinfection, ozone disinfection. The hospital needs to select according to the characteristics of sewage quality and discharge amount.
Health sewage treatment equipment Wastewater treatment standard requires that hospitals without upper and lower sewer equipment or centralized sewage treatment structures must carry out separate disinfection or other harmless treatment for infectious feces. After treatment and disinfection, the contents of pollutants and harmful substances in hospital sewage shall meet the requirements of current relevant standards. Features of health sewage treatment equipment Sewage integration equipment is made of corrosion resistant and slow reaction materials, with a long service life, saving the hospital operating costs. Through biological contact oxidation tank combined with layer upon layer filtration and disinfection devices, the sewage treatment effect is good and the problem of bacteria transmission is solved. This equipment has good deodorization effect and small amount of sludge, which will not cause other pollution hazards to the environment.
Fully automatic control system, installation damage start emergency signal system, no need for manual supervision, save labor input healthy sewage treatment equipment process and explain that the primary task of healthy wastewater treatment is to remove agricultural production system substances and suspended solids in water, and disinfect wastewater. Combined with the successful cases of health wastewater treatment in China, the sewage is treated by filtration and disinfection. The process flow of the sewage treatment project is as follows: health wastewater → collecting tank → filtration → disinfection → discharge. First, the sewage flows into a collecting tank through the pipeline (with a filter screen for preliminary filtration). The sewage in the collecting tank is transported to a small health sewage treatment equipment through the pump. In the equipment, the sewage flows into the collecting tank first, and after reaching a certain water level, The effluent is filtered and discharged under high voltage to generate ozone. The ozone and effluent are mixed and contacted to fully kill the bacteria in the sewage, and then discharged to the urban pipe network after reaching the standard.
Process selection and filtration: set up a filter screen in the sump, which is mainly used to intercept solids and blocky objects. Disinfection: The sewage in the water collecting tank is preliminarily filtered and pumped to a small health sewage treatment equipment. In the equipment, the sewage first flows into a water collecting tank in the equipment. When the water reaches a certain level, the effluent is filtered and high-voltage discharge generates ozone. The ozone and water are mixed and contacted to fully kill the bacteria in the sewage. The sewage is discharged to the urban pipe network after reaching the standard.
Process flow diagram of health sewage treatment equipment Sewage from dental sewage treatment equipment flows through the mechanical grid to remove large suspended particles and floating objects, and then flows into the regulating pool automatically. The sewage is regulated and homogenized in the regulating pool, and then lifted by sewage pump to biochemical pool A, The heterotrophic facultative microorganisms were used to remove HN3-N in sewage and degrade agricultural production systems by denitrification. Then, it flows into O biochemical tank by autotrophic aerobic microorganism to degrade the agricultural production system and nitrify the ammonia nitrogen in the sewage, and the nitrifying liquid returns to A biochemical tank for nitrogen removal treatment. The sewage flows into the sedimentation tank automatically after passing through the O biochemical tank, and the fallen biofilm and suspended solids in the biochemical tank are removed by sedimentation. The water flowing into the disinfection tank is disinfected by the chlorine dioxide generator and then discharged.
The sludge from the sedimentation tank is discharged to the sludge tank, and the sludge from the sludge tank is transported out through the belt filter press to produce sludge cake. The supernatant of the sludge tank returns to the regulating tank for further treatment. Brief introduction of dental hospital sewage treatment equipment Because hospital sewage contains a lot of original microorganisms and toxic substances, the country has formulated the "Hospital Sewage Discharge Specification", which requires that the sewage from clinics and hospitals must be subject to primary disinfection before being discharged to the municipal pipe network. Sewage disinfection treatment can generally be divided into pre-treatment before disinfection and sewage disinfection. The pre-treatment and disinfection of sewage disinfection treatment in dental clinics are often carried out together. 1、 Standards for sewage discharge in dental clinics: according to the requirements of the hospital sewage discharge standards approved for trial implementation by the Economic Commission of China and the Ministry of Health on June 1, 1983, the sewage in the clinics should be treated and disinfected before reaching the bottom. Dental hospital sewage treatment equipment - part of hospital sewage has become one of the primary sources of social water pollution. Every year, a lot of healthy wastewater is discharged, and the ingredients are messy. Relevant people remind us that we must treat different sewage differently and professionally.
Hospital sewage refers to the sewage discharged to the natural environment or urban pipelines by hospitals (dental stomatology, inductive hospitals, specialized hospitals, mass communication hospitals and other types of hospitals, blood stations, disease control centers, community health service centers). The water quality varies with the nature, planning and area of the hospital. The primary pollutants contained in hospital sewage are: * protoplasm (parasite eggs, * protobacteria, * toxin, etc.), agricultural production system substances, floating and suspended solids, radioactive pollutants, etc. The total amount of bacteria in untreated raw sewage water is more than 10 ^ 8/mL. The origin and composition of hospital sewage are disordered, containing pathogenic microorganisms, toxic and harmful physical and chemical pollutants, radioactive pollution, etc. It has the characteristics of space pollution, acute infection, latent infection, etc. Without useful treatment, it will become an important way to spread the epidemic and a serious pollution environment.
Price of sewage treatment equipment for small health clinic Hospital sewage treatment processes are still in use today, including primary treatment, secondary treatment and high-level treatment. However, secondary treatment centered on traditional activated sludge process is prevalent at home and abroad. The mission of secondary treatment is to significantly remove pollutants in the agricultural production system. Taking BOD as an example, after secondary treatment, the BOD in wastewater can be removed by 80~90%. For example, the BOD content in the water after urban sewage treatment can be less than 30 mg/l. Most treatment units of aerobic biological treatment method can meet this requirement. At present, the circulating clinic waste treatment equipment on the market includes: ozone treatment equipment with high concentration of ozone is fully dissolved in water, and dental sewage treatment equipment is introduced to form high concentration ozone water with bactericidal ability and pesticide degradation function. Chlorine disinfection equipment refers to the method that ye chlorine is vaporized and put into water through a chlorinator to complete oxidation and disinfection.
As a popular disinfectant at present, liquid chlorine is widely used in various fields. So far, sodium hypochlorite disinfection equipment is the most widely used method for water treatment and disinfection. It forms hypochlorite through its hydrolysis, and hypochlorite further decomposes to form new oxygen. The strong oxidation of new oxygen denatures the bacteria and the protein of bing toxin, thus killing pathogenic microorganisms. Chlorine dioxide disinfection equipment refers to the method of adding chlorine dioxide into water to complete oxidation and disinfection.
The equipment does not need a water collecting tank. The sewage can be connected to the water inlet of the equipment. When the sewage reaches the liquid level, it can be automatically treated. If the water level is insufficient, it will stop automatically. There is no need to add raw materials, just connect the power supply. Design requirements for sewage treatment and disinfection: dental clinics are often not large in scale, and the sewage volume is limited. Therefore, in sewage treatment design, only one sewage treatment pool or small dental wastewater treatment equipment used by the municipal Zhongneng Meiya can be built. All medical sewage in the clinic can only be discharged after it is sent to the treatment pool or sterilized in the equipment through a convenient pipeline. The design of sewage treatment tank must meet the following requirements. It should be far away from the treatment area and reception area and designed in a relatively concealed place. Anti corrosion and anti leakage facilities shall be provided.
Generally, it is made of 1cm thick melamine board. Ensure the treatment effect, safe and durable. It is easy to operate, convenient for disinfection and cleaning, and conducive to the labor protection of operators. Disinfection treatment method of clinic sewage: the small sewage treatment pool in the dental clinic generally adopts the constant volume and quantitative bleaching powder delivery disinfection method. At present, the most commonly used method is to deliver bleaching bai powder concentrate tablets twice a day, and 10-20 tablets are delivered each time according to the volume of the treatment pool. The supply of small dental stainless steel equipment uses ozone treatment, also known as ozone generator. The design of sewage treatment pool and the advantages of equipment selection: Precautions: the block baffle near the water inlet must be equipped with a stainless steel filter screen to prevent sundries from entering the electromagnetic valve and affecting the use of the valve. The timing solenoid valve automatically opens for drainage every hour to ensure that the sewage can have enough contact time with chlorine.
Price of sewage treatment equipment for small health clinic In order to prevent the sewage from overflowing the sewage treatment pool due to the sudden increase of water flow, an overflow port can be made at the height of the pool. The dosing tank must be regularly cleaned of sediment. Advantages of using ozone generator: ozone is an excellent oxidant, which can not only kill bacteria and spores with strong chlorine resistance in hospital sewage, but also remove bad odor. The ozone generator is of qualified quality and stable operation. The introduction and maintenance of dental sewage treatment equipment are convenient, which can solve the defects of traditional hospital sewage treatment, such as complex process, long process, and professional equipment maintenance and operation during operation; The ozone generated by the ozone machine is easy to decompose in water and will not cause secondary pollution due to residues.
