1, usually the equipment is buried underground, and the equipment can be covered with soil for greening or other land use.
2. The biological contact oxidation treatment process of buried sewage treatment equipment usually adopts plug-flow biological contact oxidation, and its treatment effect is better than that of fully mixed or two-stage series fully mixed biological contact oxidation tank. Compared with activated sludge tank, it has smaller volume, stronger adaptability to water quality, stronger impact load resistance, stable effluent quality and no sludge bulking. A new type of elastic three-dimensional packing is used in the tank, which has a large specific surface area and is convenient for microbial biofilm formation and stripping. Under the same organic loading condition, the removal rate of organic matter is high, and the solubility of oxygen in air in water can be improved.
3. The biochemical tank adopts biological contact oxidation method, the volume load of filler is relatively low, microorganisms are in the stage of self-oxidation, and less sludge is produced, so sludge only needs to be discharged once every three months.
4. The deodorization method of buried sewage treatment equipment is equipped with soil deodorization measures in addition to conventional high-altitude exhaust.
5. The whole equipment processing system is equipped with automatic electrical control system and equipment fault alarm system, which is safe and reliable. Usually, there is no need for special management, just need to maintain and maintain the equipment in time.
