Dental outpatient sewage treatment equipment [Literature]

oral cavity door Defilement diagnosis Water treatment equipment Literature The sewage generated by health institutions such as clinics, health centers and general hospitals, in addition to general domestic sewage, also contains chemical substances, radioactive waste water and pathogens. Therefore, it can only be discharged after treatment, especially the sewage discharged from infectious disease wards such as hepatitis, can only be discharged after disinfection. For hospitals without centralized sewage treatment equipment, infectious feces must be disinfected separately to make them harmless. Common disinfectants include chlorine dioxide, bleaching powder, liquid chlorine, sodium hypochlorite and ozone.
Sewage containing radioisotopes shall be treated according to the requirements of isotope treatment. During the treatment of hospital sewage, the precipitated sludge contains a large number of bacteria, viruses and parasite eggs, which must be disinfected (commonly used Hydrated lime Disinfection) or high-temperature compost can be used as fertilizer.
The typical process flow of small sewage treatment and chlorination disinfection is: from the ward and other Sewage containing bacteria is discharged through Water pipe The sewage shall be collected to the sewage treatment station. The fecal sewage shall be settled and digested in the septic tank before entering the sewage treatment station. The treatment station is equipped with grating, regulating tank, metering tank, lift pump and contact tank. Disinfectants enter the contact pool after being linked with the water pump or mixed with the siphon, and the sewage and disinfectant in the contact pool can be discharged after reaching the water purification and disinfection requirements after a certain time of contact. Settled sludge generated from septic tank or sedimentation tank shall be regularly eliminated and disinfected according to regulations.

Dental outpatient sewage treatment equipment [Literature] Health sewage refers to the sewage discharged by the hospital to the natural environment through the urban sewage pipeline, which was used for health work. Due to the different characteristics of hospital specialties, health conditions and health types are also different, so the composition, pathogenic bacteria and drainage volume of the health sewage produced by them are also quite different. The survey shows that the healthy sewage usually contains pathogenic microorganisms such as coliform bacteria, infectious bacteria and viruses, with chemical oxygen demand of 150~350mg/L, biological oxygen demand of 80~150mg/L, suspended solids of 40~120 mg/L and pH of 7~8.

According to the different water quality, the academic community divides health sewage into three categories: ordinary domestic sewage, clinical sewage containing pathogenic bacteria and radioactive sewage. The water volume of the three kinds of sewage has little change, and there is no discharge rule. Among them, a variety of pathogenic microorganisms and a large number are the significant characteristics of healthy sewage.

Dental outpatient sewage treatment equipment [Literature] In order to better verify the water quality, the inventor directly drank the filtered water, which was very convincing. This flat ceramic membrane is widely used, such as wastewater from Zhoushan seafood production and processing, electroplating wastewater, and oil field wastewater. After equipment treatment, the water quality is normal for drinking.
