Buried underground, the ground surface above the equipment can be used for greening or other purposes, eliminating the need for constructing houses, as well as providing heating and thermal insulation.

Product Features

1. Buried underground, the ground surface above the equipment can be used for greening or other purposes, eliminating the need for constructing houses, as well as providing heating and thermal insulation.
2. The secondary biological contact oxidation treatment process adopts plug-flow biological contact oxidation, whose treatment effect is better than that of completely mixed biological contact oxidation tanks or two-stage series completely mixed biological contact oxidation tanks. Compared with activated sludge tanks, it has a smaller volume, stronger adaptability to water quality, better shock load resistance, stable effluent quality, and no sludge bulking. The tank is equipped with new-type elastic three-dimensional fillers, which have a large specific surface area, allowing microorganisms to easily form and detach from biofilms. Under the same organic load condition, it has a high removal rate of organic matter and can improve the solubility of oxygen in the air in water.
3. The biochemical tank adopts the biological contact oxidation method. The volume load of its fillers is relatively low, and microorganisms are in the self-oxidation stage, resulting in a small amount of sludge production. Sludge only needs to be discharged once every three months (90 days or more) (either by suction with a manure truck or by dewatering into sludge cakes for outward transportation).
4. The deodorization methods of this buried domestic sewage treatment equipment include not only conventional high-altitude exhaust but also additional soil deodorization measures.
5. The entire equipment treatment system is equipped with a fully automatic electrical control system and an equipment failure alarm system, ensuring safe and reliable operation. Generally, no dedicated personnel are required for daily management; only timely maintenance and upkeep of the equipment are needed.

Usage Method

• It can treat comprehensive wastewater from domestic systems and similar organic sewage.
• It adopts a structure made of fiberglass-reinforced plastic (FRP) and stainless steel, which has excellent properties such as corrosion resistance and aging resistance, with a service life of more than 50 years.
• The entire set of equipment features simple construction and easy operation. All mechanical equipment is controlled automatically, and the entire device can be installed underground.
