Underground Sewage Treatment Equipment

█ Equipment Introduction

The underground sewage treatment equipment is a complete set of organic wastewater treatment devices designed by our company based on the internationally prevalent sewage treatment principles, combined with our own scientific research achievements and engineering practices. This equipment adopts advanced processes and manufacturing technologies from the late 1990s, producing the YM series sewage treatment equipment primarily made of fiberglass and stainless steel. Its main purpose is to treat domestic sewage and similar industrial organic wastewater to meet the discharge standards required by users. The equipment is mainly used for domestic sewage treatment in residential areas (including villa communities), high-end hotels, hospitals, comprehensive office buildings, and various public buildings. The effluent quality after treatment meets national discharge standards. The entire set of equipment can be buried underground, hence it is also called "Underground Domestic Sewage Treatment Equipment".

█ Product Features

1. Buried below the surface, the ground above the equipment can be used for greening or other purposes, eliminating the need for building houses, heating, or insulation.

2. The secondary biological contact oxidation treatment process adopts a plug-flow biological contact oxidation method, which offers better treatment effects than completely mixed or secondary series completely mixed biological contact oxidation tanks. It has a smaller volume than activated sludge tanks, strong adaptability to water quality, good impact load resistance, stable effluent quality, and avoids sludge bulking. The tank uses a new type of elastic three-dimensional filler with a large specific surface area, making it easy for microorganisms to form and shed biofilms. Under the same organic load conditions, it achieves a high removal rate of organic matter and increases the solubility of oxygen in the air.

3. The biochemical tank uses the biological contact oxidation method, with a relatively low volumetric load of the filler. Microorganisms are in the endogenous respiration phase, resulting in low sludge production. Sludge only needs to be discharged once every three months (90 days) or more (extracted by sewage trucks or dehydrated into sludge cakes for transport).

4. In addition to conventional high-altitude exhaust for deodorization, this underground domestic sewage treatment equipment is also equipped with soil deodorization measures.

5. The entire equipment treatment system is equipped with a fully automatic electrical control system and a device 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.

█ Scope of Application

1. Hotels, restaurants, sanatoriums, hospitals;

2. Residential communities, villages, towns;

3. Stations, airports, seaports, ships;

4. Factories, mines, military units, tourist spots, scenic areas;

5. Various industrial organic wastewater similar to domestic sewage.

4. If our service is unsatisfactory, you can call or write to complain and provide your valuable opinions and suggestions to help us improve our service. We sincerely thank you for this!

The principle of integrated equipment for sewage treatment is based on the organic combination of activated sludge microbial methods and biofilm biological methods for biochemical sewage treatment. In terms of treatment process, a large number of microorganisms grow on fixed and floating biological carriers to form biofilms. As water and air impact and agitate the sewage, bacteria and biofilms are renewed. During aeration, biological carriers are used to improve the contact efficiency between microorganisms, pollutants in the sewage, and oxygen. The alternating effects of anaerobic, anoxic, and aerobic environments generated by the overall treatment equipment enhance the purification capacity of different types of microbial communities for sewage, strengthening the removal of organic matter and the efficiency of denitrification and phosphorus removal.

Scope of Application: Industrial and urban sewage treatment fields.
