Hengshui9 major features of integrated domestic sewage treatment equipment products:

1. Buried below the surface, 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 takes more than three months (90 days) to discharge the sludge (using fecal trucks to suction or dehydrate into sludge cakes 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 and equipment fault alarm system, which operates safely and reliably. Generally, there is no need for dedicated personnel to manage it, and only timely maintenance and upkeep of the equipment is required.

6. Using A/O composite biological contact oxidation method, the equipment performance is stable and the treatment effect is good;

7. Widely used for deep processing in residential areas, mining areas, township hospitals, food, slaughtering, breeding and other industries;

8. The equipment can be buried underground and covered with soil for greening, occupying less land;

9. The equipment has low operating costs and saves labor costs.

2、 Several usage methods of integrated domestic sewage treatment equipment

• Capable of treating comprehensive wastewater from living systems and similar organic wastewater;

• It is made of glass fiber reinforced plastic and stainless steel, and has excellent characteristics such as corrosion resistance and aging resistance, with a service life of more than 50 years;

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 integrated domestic sewage treatment equipment

1. Hotels, restaurants, sanatoriums, hospitals;

2. Residential communities, villages, and towns;

3. Stations, highway service areas, seaports, and ships;

4. Factories, mines, troops, tourist attractions, scenic spots;

5. Various industrial organic wastewater similar to domestic sewage, such as the food industry.
