domestic sewage treatment plant

Product description:

Domestic sewage treatment plant is an underground plant which adopts the advanced Biological technology and the company’s scientific research and engineering practice result, it can effectively remove BOD5,COD and NH3-N. The device is characterized by the stable performance, effective treatment, economical investment, automatic operation, convenience of maintenance and small occupying space. There is no need for construction, neither heating and heat preservation.The surface can be used as green land or square land.It also can be placed on ground based on client's requirement.

    As the most efficient sewage treatment device, it is widely used in treating the sewage in the area of senior hotels, village districts and residential districts, etc. The water after treatment would meet the national emission standards. The water after be treated can be used to irrigation.

Application:

(1) Hotel, restaurant, sanatorium, hospital, school effulent treatment;
(2) Residence community, villa district, village, town effulent treatment;
(3) Station, airport, seaport and dock effulent treatment;
(4) Factory, mine, army, beauty spot effulent treatment;
(5) All kinds of industrial sewage similar to the living domestic effulent, etc

Features: 

1, Compact design, which is easy to transport.

2, Integrated device, no need construction, which is easy to be installed.

3, Full Automatic machine, which is easy to operate and maintain.

4, Can be fixed on underground, which can save room and earth. 

5, Don't need additional construction, the total cost is small.

Techincial parameter:

Note: we can design the different size based on the different water capacity(m3/h).

Application Site:

Working Principle:

The sewage enters the grid well first, and after removing the particulate matter from the grille, it enters the regulating tank, adjusts the water quality and quantity, and then is pumped to the primary sedimentation tank by the lift pump. The wastewater flows to the Class A biological contact oxidation tank for acidification hydrolysis and nitrification. Denitrification, reduce the concentration of organic matter, remove part of ammonia nitrogen, and then enter the O-level biological contact oxidation tank for aerobic biochemical reaction. Most of the organic pollutants are degraded by biooxidation, and the effluent flows to the secondary sedimentation tank for solid-liquid treatment. After separation, the supernatant of the sedimentation tank flows into the clear water tank, and the disinfection equipment is used to kill the harmful bacteria in the water and reach the standard discharge. The debris left by the grille is periodically loaded into the trolley and dumped to the garbage dump. The sludge in the secondary sedimentation tank is partially returned to the A-stage biological treatment tank, and the other sludge is discharged to the sludge tank for sludge dewatering and periodically sucked. The supernatant of the sludge tank is returned to the conditioning tank for further treatment.
