Buried Integrated Domestic Sewage Treatment Equipment

I. characteristics and difficulties of buried sewage treatment

Buried sewage treatment equipment is a modular and efficient wastewater biological treatment equipment, is a kind of biological membrane as the purification of wastewater biological treatment system, give full play to the anaerobic biological filter, such as contact oxidation bed biofilm reactor has a large biological density, resistance to strong carrying capacity, low power consumption, low operating characteristics of stable running, convenient maintenance, makes the system has a wide application future and spreding value.This design for a village of small sewage treatment in the production of life.The quality of domestic sewage is complex, containing a large number of bacteria, viruses, parasitic worm eggs and toxic and harmful substances.

Ii. Buried sewage solution and treatment process features:

There are a variety of buried sewage treatment technologies. On the premise of reaching the effluent standard, the most prominent advantages are:

1. The equipment is buried under the surface of the earth, which can be afforested with beautiful environment.

2. The entire equipment generally does not need special management.

3. The floor space can be reduced. Parking lot can be built above the equipment, and other facilities such as factory buildings need not be built.

4. No impact on the surrounding environment, less sludge production and less noise than the standard of type ii areas.

5. Simple operation, new technology, good effect, long service life.

6. The equipment can be arranged according to the standard or according to the needs of the terrain.

Disadvantages:

1. It is not conducive to maintenance. It is not convenient to repair and replace the equipment after failure.This is often the owner's biggest worry.

2. Strong adaptability to the environment, anti-freezing in winter and flood control in summer.

Under what conditions is it suitable to use buried sewage treatment equipment?The water quantity is small, the pollutant concentration is small, the composition is not complex, the site is limited, needs to consider the surrounding environment beautification factor and so on.Generally, it is recommended to use buried sewage treatment system for treatment under the above situations.The use of the improved anaerobic + aerobic treatment process, the design is to pay attention to sewage, sludge sterilization.The key is to kill the pathogen.The effluent quality was good, and the concentrations of BOD, nitrogen, phosphorus and suspended matter were low.Short process, less equipment, small area;Easy to control automatically and so on.
