Buried domestic sewage in villages Water treatment equipment Integrated price
There are many sewage treatment processes used at home and abroad, including activated sludge process and biofilm process. The common aeration method, oxidation ditch method, A/B method, A two /The O method belongs to the former, while the biological rotary table and contact oxidation method belong to the latter. The integrated sewage treatment equipment is a device that integrates the primary sedimentation tank, I and II level contact oxidation tank, secondary sedimentation tank and sludge tank, and carries out air blast aeration in the I and II level contact oxidation tank to effectively combine the contact oxidation method and activated sludge method. At the same time, it has the advantages of both, overcomes the disadvantages of both, and further improves the sewage treatment level.
Integrated price of village buried domestic sewage treatment equipment advantage
1. The ability to resist shock load is strong, and the average residence time of contact oxidation method is more than 6 hours.
2. It has the ability of nitrogen and phosphorus removal, and can achieve the ability of treating industrial wastewater, domestic sewage and urban sewage by adjusting the structure of the equipment.;
3. Contact with filler Most of them are combined soft fillers, light in weight, high in height, stable in physical and chemical properties, large in specific surface area, strong in biofilm adhesion, and high in contact efficiency between sewage and biofilm.
4. Aerator is used in the contact oxidation tank for air blowing aeration, so that the fiber bundle can float continuously, aeration is uniform, and microorganisms grow mature, which has the characteristics of activated sludge process.
5. The effluent quality is stable, the sludge output is small and easy to treat.
6. Diving pump It can be installed in equipment to reduce project investment.
7. The equipment can be installed on the ground or buried underground. When buried underground, the upper part can be used for greening. The plant area is small and there are few ground structures.
8. Easy to complete automatic control and simple management operation.
9. The equipment can be connected to a car to form a mobile integrated sewage treatment equipment.
1. Grating:
The sewage discharged from production is collected by the pipe network system, and then enters the follow-up treatment system after passing through the coarse screen. The coarse screen is mainly used to intercept large floating objects in the sewage to ensure the normal operation of subsequent treatment structures and effectively reduce the treatment load, so as to ensure the long-term normal operation of the system.
2. Sewage regulating tank:
It is used to regulate the water quantity and uniform water quality so that the sewage can enter the subsequent treatment unit more evenly. The pre aeration system is set in the regulating tank, which can improve the impact resistance of the whole system, reduce the foul smell of sewage under anaerobic state, and reduce the design scale of the subsequent treatment unit. The submersible sewage pump is set in the sewage tank to lift the sewage to the subsequent treatment unit.
3. Anoxic tank:
An elastic filler is set in the anoxic tank to intercept the fine suspended solids in the sewage and remove some organics. The returned nitrified liquid of the anoxic tank is used for denitrification, which improves the removal rate of ammonia nitrogen in sewage. The sewage after anoxic treatment enters the aerobic biological treatment tank.
4. Contact oxidation tank:
Most organics in the raw sewage water are degraded and purified here. Aerobic bacteria use fillers as carriers and organics in the sewage as food materials to decompose organics in the sewage into inorganic salts, so as to achieve the purpose of purification. The survival of aerobic bacteria must have enough oxygen, that is, there is enough dissolved oxygen in the sewage to achieve the purpose of biochemical treatment. The air of the aerobic tank is provided by the fan. The tank uses a new semi soft biological filler. The filler has a large surface area ratio, long service life, easy film hanging, and corrosion resistance. The bottom of the tank uses a microporous aerator, which makes the transfer rate of dissolved oxygen high. At the same time, it has the advantages of light weight, non aging, non clogging, and long service life. Two major accessories in the contact oxidation tank:
Integrated price of village buried domestic sewage treatment equipment Equipment characteristics
Convenience
1. The overall assembly and commissioning of the equipment is completed in the factory, eliminating the complicated construction, installation and commissioning process on site.
The equipment can be buried below the ground, outdoor or indoor.
2. Regulating tank, sludge tank, anoxic tank, biological contact oxidation tank, secondary sedimentation tank and disinfection tank are highly integrated into one
In the integrated equipment, the treated water volume is from 1-
80(m3/h)。
3. Modular fan room: the fan, sludge discharge controller and automatic control cabinet are integrated and installed in the fan room.
***Rate
1. The equipment adopts submersible aerator or low-noise blower, with high aeration efficiency, stable operation and low noise.
2. The company's special biological packing is used. Aerobic bacteria grow outside the packing and anaerobic bacteria grow inside the packing. There are nitrification and denitrification processes at the same time during the whole treatment process, which can simultaneously remove nitrogen and organic matter in the micro unit. The new biological filler has high specific surface area and high biomass per unit volume, which increases the equipment volume load by 1.5 times. When the influent BOD5 reaches 400mg/L, the equipment effluent is still stable and up to standard. 3. The facultative tank has the function of sludge backflow and reverse digestion, providing a large number of biological bacteria for the follow-up biochemical system to achieve good nitrogen and phosphorus removal effects
low cost
1、
Low civil construction cost:
Due to the integrated design, it is unnecessary to make any reinforced concrete pool body, but only need to dig one
Integrate the equipment foundation pit, prepare the cushion, and backfill after placing the equipment. The upper part of the equipment can be used as a green belt,
For parking lots, roads, etc., the construction period of civil works is greatly shortened and the cost is saved.
2、
Low equipment cost:
use Glass Steel box, modular design, factory scale production, fast speed
Short production period
3、
Low operation cost:
Innovative process, excellent design, and the use of * * * biological filler make the whole set
Integrated price of village buried domestic sewage treatment equipment The sewage treatment system * * * operates, reducing the sewage treatment cost per ton to below 0.3 yuan. Where solar energy and wind energy are used, our company's scenery integration can be added alternator Group provides power for sewage treatment equipment, which can make the electricity charge for sewage treatment zero.
