The integrated domestic sewage treatment equipment adopts the world's advanced biological treatment process, which integrates the removal of BOD, COD, and NH-N, and is currently the most efficient and convenient sewage treatment equipment. It is widely used in the treatment of domestic sewage in hotels, restaurants, shopping malls, highway service areas, office buildings, residential communities, villages, towns, factories, mines, military forces, tourist attractions, scenic spots, etc., replacing septic tanks with low removal rates and treated effluent that cannot meet national comprehensive discharge standards. Through practical application, it has been shown that the WSZ domestic sewage treatment device is a highly effective and easy to manage equipment.

II Product Features

(1) It can be buried underground and the surface can be used as green or square land, so the equipment does not occupy the surface area, does not require building, and does not require heating and insulation.

(2) Composed of two sets of equipment made of steel structure, using domestically pioneered anti-corrosion coating for corrosion prevention. It is resistant to acid, alkali, salt, gasoline, kerosene, aging, abrasion, and rust. After applying the coating, the anti-corrosion life of the equipment can generally reach more than 15 years.

(3) The AO biological treatment process adopts a push flow biological contact oxidation tank, which has a better treatment effect than fully mixed or two-stage series fully mixed biological contact oxidation tanks. And it has a smaller volume than activated sludge tanks, stronger applicability to water quality, good impact resistance, stable effluent water quality, and will not cause sludge expansion. At the same time, a new type of elastic three-dimensional material is used in the biological contact oxidation tank, which has a larger actual specific surface area, microbial biofilm formation, and convenient membrane removal. Under the same organic load conditions, it has a higher removal rate of organic matter than other fillers. Can increase the solubility of nutrients in water in the air.

(4) Due to the use of a biological contact oxidation tank in the AO biological treatment process, the volume load of the packing is relatively low, and the microorganisms are in the self oxidation stage, resulting in less sludge production. In addition, the moisture 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 generated by the WSZ series sewage treatment equipment is relatively small, and generally only needs to be discharged once every 90 days.

(5) In addition to using conventional measures such as vibration isolation pads and silencers, new sound-absorbing materials have also been installed on the inner wall of the blower room, reducing the noise level during equipment operation to below 50 decibels and minimizing its impact on the surrounding environment.

(6) Equipped with soil deodorization measures, it utilizes the upper space of the reinforced concrete structure pool to set up improved soil and air distribution pipes. When odorous components dissolve in the water contained in the soil through the soil layer, they are then transferred into the soil due to surface adsorption and chemical reactions, and ultimately decomposed by microorganisms to achieve deodorization.

(7) The fully automatic electrical control system and equipment damage alarm system have good reliability, so there is generally no need for dedicated personnel to manage them, only monthly or quarterly maintenance and upkeep are required.
