Integrated domestic sewage treatment equipment

Integrated domestic sewage treatment equipment:

It is mainly used for small sewage treatment projects, such as small sewage treatment projects in residential areas, hospitals, scenic spots, stations, service areas, etc., mainly using traditional AO,A2

O process, its processing flow;

The sewage first enters the water collection conditioning tank for water quantity and quality regulation, and the water collection regulating tank is provided by the user. General selection of concrete pool body, users can determine the adjustment according to the consumption process, water quality, water fluctuation. The residence time of the regulating tank is 6-12 hours, and then it enters the integrated sewage treatment equipment through the lifting pump, and the water of the equipment can be discharged.

The equipment mainly includes;

1, the initial sedimentation tank: using vertical sedimentation tank, sewage flow rate of 0.5-0.8mm/s. The sludge should be lifted by air to the sludge tank. It can be merged with the water collection conditioning tank to form the initial settling conditioning tank with a residence time of 5-6.0hr.

2, contact oxidation pool: contact oxidation pool is divided into three levels. Total residence time is 4.5-12.0hr with built-in packing. The aeration unit uses a microporous aerator. Greatly improve the use of oxygen efficiency, thereby reducing energy consumption. The water to air ratio is usually 1:15-20.

3, the second sedimentation tank: the second sedimentation tank is the inclined plate sedimentation tank. Total stay time is 1-2Hr.

4. Disinfection tank: the contact time of disinfection tank is 30min according to the specification, and the special sewage can be extended to 1-1.5ht. Generally, solid chlorine tablets are used for disinfection (other disinfection installations can be equipped according to customer requirements), and the disinfection tank can be eliminated after the disposal of industrial inorganic sewage.

5, sludge tank: All sludge in the primary sedimentation tank and secondary sedimentation tank is discharged to the sludge tank to stop aerobic clearance. The supernatant flows back to the contact oxidation tank. Due to the small amount of residual sludge, it is usually liquidated once after 9-15 months of operation.

Sewage in life can be described as a single variety, a variety of, we should do the corresponding classification obligations when we suspend the disposal, rather than consciously suspend, then, we will look at the final disposal of domestic sewage water purification equipment in our lives those effects. Installation, commissioning, maintenance

Equipment problems;

1, many production companies do not have strict design technology, but blindly consider the cost of equipment, resulting in equipment operation can not achieve the expected treatment effect, so that the acceptance can not reach the standard.

2, many production companies do not understand the detailed construction principle of the equipment, but blindly imitate the shape and structure of the equipment, resulting in the equipment can not run, the processing effect can not meet the standard, so that the equipment is presented as a display.

3, the internal design of the equipment is unreasonable, easy to appear uneven distribution, dead corners and other problems

The technical department of our company through reasonable calculation, combined with the actual testing data of many cases of the company, combined with the original data of each project, gives a reasonable processing plan and technical parameters. If you have technical problems, please contact us.

Order specification

1, because the equipment is buried equipment, maintenance is more difficult, so we think about its maintainability when designing and manufacturing the equipment, and colleagues are equipped with introspection holes to facilitate the repair of sudden problems.

Online consultation

2, the equipment with ordinary Q235 steel plate to stop manufacturing, external use of ordinary anti-corrosion, the ordinary life of up to 10 years or more.

3, the lifting pump of the equipment adopts the anti-infarct tear type submersible pump, which can effectively tear the solid particles with a diameter of 30~80mm and can tear the long fiber material, without adding a filter screen at the pump inlet. The pump has operated safely for more than 8,000 hours. The air room is configured independently.

4. The user only needs to turn on the power supply of the equipment, connect the import and export pipes of the equipment and the pipes between each unit of the equipment to put into normal operation.

5. If the special requirements of the frozen soil layer in the user's region must be declared at the time of ordering. In order to adjust the height of the reflection hole according to the thickness of the frozen layer in the area where the user equipment is used.
