Buried sewage treatment equipment integrated sewage treatment equipment domestic sewage treatment equipment

An overview,

This treatment equipment is specially built for domestic sewage treatment.

Determination of treatment process: according to the specific characteristics of domestic sewage, this process is adopted;A/O composite biological contact oxidation treatment process, the treatment process is easy to operate, manage and run, the daily cost is low, the water is stable.

Buried sewage treatment device: the main structure of the equipment adopts steel structure integrated combination form, the layout is fully buried, the operation mode of the equipment is automatic operation, maintenance free operation management.

1. Adopt the mature A/O biochemical treatment process, which has A good function of removing organic matter in sewage and denitrifying, so as to meet the requirements of discharge standards;

2. It has a good impact bearing capacity to adapt to the changes in water quality and quantity;

3. Pre-denitrification is adopted in the process. In the process of denitrification, organic matter in sewage is used as the carbon source for reaction, which greatly reduces organic matter and reduces the concentration of organic matter after biochemical treatment.

4, the use of new packing, quick hanging film, long life, quick treatment;

5. Fully consider the possibility of secondary pollution and reduce its impact to a low degree;

6. Adopt centralized control and automatic operation, easy to manage and maintain, and improve system reliability and stability.

7. The treatment facilities of the system are all set below the surface of the earth with no surface area, which can be used for greening and is conducive to anti-freezing.

Ii. Operation and use of buried integrated equipment:

(1) fill the aeration tank with sewage through manual switch, then stop the water intake and start aeration.

(2) aeration without water is referred to as static aeration;.After aeration for 2 ~ 3 days, stop aeration and quietly sink for 3 hours, then enter part of fresh sewage, which accounts for about 1/5 of the pool capacity.

(3) after the cycle of the three processes of static aeration, static sedimentation and water intake, but each time the water intake should be increased than the last time, each time the time should be shortened than the last time, that is, the number of water intake increased.
