Introduction to the advantages of buried integrated sewage treatment equipment

With the growth of the economy and population, the pollution of nature has been increasingly valued by humans. Based on the summary of the operating experience of domestic and foreign sewage treatment devices, a complete set of organic wastewater treatment devices that can be buried has been designed. The equipment adopts advanced processes and manufacturing technologies from the 1990s at home and abroad, and produces sewage treatment equipment mainly made of fiberglass and stainless steel. The main purpose is to meet the discharge standards required by users after treating domestic sewage and similar industrial organic wastewater with this equipment. The equipment is mainly used for the treatment of domestic sewage in residential communities (including villa communities), high-end hotels, hospitals, comprehensive office buildings, and various public buildings. The effluent quality treated by the equipment meets the national discharge standards. The entire set of equipment can be buried underground, hence it is called "buried domestic sewage treatment equipment". The buried domestic sewage treatment equipment adopts internationally advanced biological treatment technology, which can remove BOD5, COD, and NH3-N. The technical performance is stable and reliable, the treatment effect is good, the investment is low, the land occupation is small, and the maintenance is convenient.

The design of buried domestic sewage equipment is mainly aimed at the treatment of domestic sewage and similar industrial organic sewage. The main treatment method is to use a relatively mature biochemical treatment technology - contact oxidation method. The water quality parameters are designed according to the general domestic water quality, with an inlet bod of 200 mg/l and an outlet bod of 20mg/l. It consists of six parts: (1) primary sedimentation tank; (2) Contact oxidation tank; (3) Secondary sedimentation tank; (4) Disinfection pool and disinfection device; (5) Sludge tank; (6) Fan room, fan.

1、 Advantages of buried sewage treatment equipment:

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.
