The buried domestic sewage treatment equipment adopts the world's advanced biological treatment process, integrating the removal of BOD5, COD, NspanN in one, is currently the better effect of sewage treatment equipment.
The buried domestic sewage treatment equipment is widely used in the comprehensive sewage treatment of high-level hotels, villa districts, hospital wastewater and residential districts, replacing the septic tank which has a very low removal rate and the treated effluent fails to meet the national comprehensive emission standards. After the actual application shows that WSZ-AO series integrated sewage treatment equipment is a treatment effect is very ideal and easy to manage the equipment.
Since the biological contact oxidation tank is used in the AO biological treatment process, the volume load of its filler is relatively low, and the microorganisms are in the stage of their own oxidation, so the amount of sludge produced is less. In addition, the water content of the sludge produced by the biological contact oxidation tank is much lower than that of the sludge produced by the activated sludge tank. Therefore, the amount of sludge produced by WSZ-AO series integrated sewage treatment equipment is less.
Expanded Information:
Rural buried domestic wastewater features:
1, integrated wastewater treatment equipment can be buried below the surface of the ground, the surface can be used as green or plaza land, so the equipment does not occupy the surface area, do not need to cover the room, and even less heating insulation.
2, integrated wastewater treatment can be reinforced concrete structure or steel structure, can also be made of fiberglass.
3, integrated wastewater treatment equipment in the AO biological treatment process using push-flow biological contact oxidation tank, which is superior to fully mixed or two or three tandem fully mixed biological contact oxidation tank. And it is smaller than the activated sludge tank, strong adaptability to water quality, good impact resistance, stable effluent water quality, will not produce sludge expansion.
At the same time in the biological contact oxidation tank using a new type of elastic three-dimensional packing, which has a large surface area, microbial film, easy to remove the film, in the same organic load conditions, than other fillers on the removal of organic matter is high, and can improve the air in the water solubility of oxygen.
4, integrated wastewater treatment equipment supporting fully automatic electrical control system and equipment damage alarm system, equipment reliability, so usually do not need to be managed, only the monthly quarterly maintenance and repair.
