1. Sewage treatment is composed of two pools, with steel structure and shallow burial depth, which can withstand acid, alkali, salt, gasoline, kerosene, aging resistance, erosion resistance and rust prevention.After equipment besmear brushs this coating commonly, anticorrosive life can reach 12 years above.

2. In the biological treatment process of domestic sewage treatment equipment, the push-flow biological contact oxidation tank is adopted, which is better than the fully mixed or the two or three stage series fully mixed biological contact oxidation tank.Moreover, it is smaller than activated sludge tank, has strong adaptability to water quality, good impact resistance, stable effluent water quality and no sludge swelling.At the same time, a new elastic solid filler is used in the biological contact oxidation tank, which has a large specific surface area, and is convenient for hanging and stripping the membrane of microorganisms. Under the same organic load, it has a higher removal rate of organic matter than other fillers, and can improve the solubility of oxygen in air in water.

3. Due to the use of biological contact oxidation tank in the biological treatment process, the volume load of the filler is relatively low, and the microorganisms are in their own oxidation stage, so the amount of mud is less.In addition, the water content of the sludge produced by the biological contact oxidation tank is much lower than that of the activated sludge tank.Therefore, the amount of sludge produced by sewage treatment equipment is less, generally only about 90 days of mud discharge.

4, domestic sewage treatment equipment in addition to the use of conventional measures of noise muffler blower (such as vibration isolation pad, muffler, etc.), but also in the wall of the blower room set up a new sound-absorbing material, so that the equipment operating noise is less than 50 db, reduce the impact on the surrounding environment.

5, stainless steel domestic sewage treatment equipment supporting automatic electrical control system and equipment damage alarm system, equipment reliability is good.

6, domestic sewage treatment equipment can be buried below the surface, the surface can be used as a green or square land, so the equipment does not cover the surface area, do not need to build houses, and do not need heating and insulation.
