The secondary biological contact oxidation treatment process of the entire domestic sewage equipment adopts push flow biological contact oxidation, which has a better treatment effect than the fully mixed biological contact oxidation tank. It is smaller than an activated sludge tank, with better water quality, better resistance to impact loads, stable effluent quality, and no sludge expansion. Equipped with a new type of elastic three-dimensional packing material in the pool, it has a large surface area and is easy for microorganisms to suspend the membrane. Under the same organic loading conditions, the removal rate of organic matter is high and the solubility of oxygen in air can be improved.
The biochemical tank adopts the biological contact oxidation method, and the volume load of the packing is relatively low. Microorganisms are in the stage of self oxidation, and the amount of sludge is small. Only need to discharge the mud once every three months (90 days). The entire system is equipped with a fully automatic electrical control system and equipment fault alarm system. Operational safety ******. In general, there is no need for dedicated personnel to manage, and equipment needs to be maintained and serviced in a timely manner.
Scope of application: 1. Hotels, restaurants, sanatoriums, hospitals; 2. Residential communities, villages, and towns; 3. Stations, airports, seaports, and ships; 4. Factories, schools, mines, troops, tourist attractions, scenic spots; 5. Various industrial organic wastewater similar to domestic sewage.
