Integrated sewage treatment equipment is a commonly used equipment in sewage treatment projects, which is widely used in both urban and rural areas. The main advantages of integrated sewage treatment equipment are as follows.

1. Save space

The integrated sewage treatment equipment 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. Long service life

The integrated sewage treatment equipment consists of two levels of tanks. The first level is a reinforced concrete structure with a larger burial depth, while the other group is a steel structure with a shallower burial depth. The steel structure pool adopts the domestically pioneered interpenetrating network anti-corrosion coating for corrosion prevention. It is an interpenetrating polymer formed by the interpenetrating of rubber and plastic networks. 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. Good cleaning effect

The AO biological treatment process in the integrated domestic sewage treatment equipment 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, strong adaptability to water quality, good impact resistance, stable effluent quality, and will not cause sludge expansion. At the same time, a new type of elastic three-dimensional packing material was used in the biological contact oxidation tank, which has a large actual specific surface area and is convenient for microbial biofilm formation and detachment. Under the same organic load conditions, it has a higher removal rate of organic matter than other packing materials and can improve the solubility of oxygen in water.

4. Low sludge production

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 series of sewage treatment equipment is relatively small, and generally only needs to be discharged once every 90 days.

5. Good deodorization effect

The integrated domestic sewage treatment equipment is equipped with soil deodorization facilities. It utilizes the upper space of the reinforced concrete structure pool to set up improved soil and gas pipes. When the odorous components dissolve in the water contained in 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.
