Integrated new rural sewage treatment system

Integrated new rural sewage treatment system

Integrated new rural sewage treatment system——Scope of application:

The treatment of domestic sewage in highway service areas, airports, high-speed rail service areas, hotels, nursing homes, hospitals, schools, residential communities, villa communities, etc.

The treatment of wastewater from aquatic processing plants, livestock processing plants, fresh milk processing plants, and other production facilities.

——Process flow

Using the biological treatment process of *, based on summarizing the operating experience of domestic and foreign domestic sewage treatment devices, combined with our own scientific research achievements and engineering practice, we have designed an integrated residential sewage treatment device. The design of residential sewage treatment mainly adopts the currently mature biochemical treatment technology, contact oxidation method, which generally consists of six parts: (1) primary sedimentation tank, (2) contact oxidation tank, (3) secondary sedimentation tank, (4) disinfection tank and disinfection device, (5) sludge tank, (6) fan room and fan components. Through the above processes, the sewage can be discharged in compliance with standards.

——Facility Description

a、 grille

The grille is fixed and made of stainless steel mesh. Set up two layers, coarse and fine, to remove suspended particles and floating impurities from water.

Process Characteristics

Adopting mature A/O biochemical treatment technology, it has good removal of organic matter in sewage and good denitrification function to meet the requirements of discharge standards;

Has good shock load resistance to adapt to changes in water quality and quantity;

The process adopts pre denitrification. Due to the reaction of organic matter in sewage as a carbon source during the denitrification process, the organic matter is greatly reduced, and the concentration of post biochemical treatment organic matter is reduced;

Adopting a new type of filler, it has fast film hanging, long service life, and fast treatment effect;

Fully consider the possibility of secondary pollution and reduce its impact to a certain extent;

Adopting centralized control and automated operation, it is easy to manage and maintain, and improves system reliability and stability.

The system processing facilities are all located below the ground surface, without occupying any surface area, which can be used for greening and is also conducive to anti freezing.

An adjustable weir is installed on the upper part of the sedimentation tank to regulate the water level of the effluent; The lower part is equipped with a conical sedimentation zone and a sludge air lifting device, with the air source provided by a fan. The sludge is transported to the sludge tank by air lifting.

Scope of Application

The integrated sewage treatment equipment is suitable for domestic sewage treatment in residential areas, restaurants, hotels, nursing homes, schools, mines, factories, slaughterhouses, and similar industrial sewage treatment.

On the basis of summarizing the operating experience of domestic and foreign domestic sewage treatment devices, combined with scientific and technological achievements and engineering practice, a complete set of organic wastewater treatment devices that can be buried is designed, which is a series of sewage treatment equipment mainly made of carbon steel anti-corrosion materials. The main purpose is to meet the discharge standards required by users after treating domestic sewage and similar industrial organic wastewater with this equipment. This device is mainly used for the treatment of domestic sewage in residential communities (including villa communities), high-end hotels, hospitals, slaughterhouses, comprehensive office buildings, and various public buildings. The effluent quality treated by this device meets the discharge standards.
