CHARACTERISTICS
1. The complete set of equipment can be buried below the frozen layer or placed on the ground. The surface above the equipment can be used for greening or other purposes, without the need for building houses, heating, or insulation.
2. The secondary biological contact oxidation treatment process adopts push flow biological contact oxidation, 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 shock load resistance, stable effluent quality, and will not cause sludge expansion. A new type of elastic three-dimensional packing material is used in the pool, with a large specific surface area and easy biofilm formation and detachment by microorganisms. Under the same organic load conditions, 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, which has a relatively low volume load of the filling material, and the microorganisms are in their own oxidation stage, resulting in low sludge production. It only requires 3 to 6 months or more to discharge the sludge (using a manure truck to suction or dehydrate it into a sludge cake for external transportation).
4. The deodorization method of this buried domestic sewage treatment equipment not only uses conventional high-altitude exhaust, but also includes soil deodorization measures.
5. The entire equipment processing system is equipped with a fully automatic electrical control system, which operates safely and reliably. Generally, there is no need for dedicated personnel to manage it, only timely maintenance and upkeep of the equipment is required.

2、 Several usage methods of buried domestic sewage treatment equipment
• Capable of treating comprehensive wastewater from living systems and similar organic wastewater;
• It is made of anti-corrosion steel or glass fiber reinforced plastic, with excellent characteristics such as corrosion resistance and aging resistance.
The complete set of equipment is simple to construct and easy to operate. All mechanical equipment is automatically controlled, and all devices can be installed below the surface;

3、 Scope of application of buried domestic sewage treatment equipment
1. Hotels, restaurants, sanatoriums, hospitals;
2. Residential communities, villages, and towns;
3. Stations, airports, seaports, and ships;
4. Factories, mines, troops, tourist attractions, scenic spots;
5. Various industrial organic wastewater similar to domestic sewage.
