Release time:
2023-12-08
The buried integrated sewage treatment equipment is a sewage treatment device based on A/O biochemical process, which integrates biological degradation, physical precipitation, chemical disinfection and other processes, and is widely used in hospital sewage treatment. The equipment has compact structure, small area, all set up underground, economical operation, strong impact load resistance, high processing efficiency, convenient management and maintenance. The performance of the device meets the relevant requirements and has been recognized by the State Environmental Protection Administration.
Characteristics of buried integrated sewage treatment equipment
① It can be buried below the surface, and the top of the equipment is provided with a hole cover, which is integrated with the surrounding lawn;
No impact on the surrounding environment, sludge attached to the filler, strong impact load, less loss;
Fully automatic control, no need for professional management.
④ Simple operation, convenient maintenance, new technology, good effect and long service life.
⑤ The equipment can be arranged according to the standard or special arrangement according to the terrain.
Process principle of buried integrated sewage treatment equipment
Buried sewage treatment equipment is a modular and efficient sewage biological treatment equipment, which is a biological treatment system with biofilm as the main body of purification. It gives full play to the biochemical treatment process of hydrolysis acidification and contact oxidation. It has the characteristics of high biological density, strong pollution resistance, low power consumption, stable operation and convenient maintenance, which makes the system have a wide application prospect and popularization value.
Process Description of Buried Integrated Sewage Treatment Equipment
The design of the equipment is mainly for the treatment of hospital sewage. The main treatment method is to adopt a more mature biochemical treatment technology-biological contact oxidation method. The design of inlet water quality parameters is designed according to the reference data of hospital sewage quality indicators, and the outlet water indicators meet the water pollutant discharge standards of medical institutions.
Civil structures in the sewage station are divided:
(1) Grille regulating pool
(2) Accident pool
(3) Contact disinfection tank
(4) Drain
(5) Sludge tank
(6) Equipment room
(7) Integrated equipment foundation
Buried integrated sewage treatment equipment process flow
1. The effluent from the septic tank enters the grid well of the sewage treatment station, and the large particle pollutants in the sewage are intercepted by the grid to prevent it from blocking the subsequent pumps and other structures.
2. The water from the grid well enters the regulating tank to adjust the water quality and quantity of hospital wastewater, so as to reduce the impact of the change of water quality and quantity on the subsequent treatment structures.
3. The wastewater in the regulating tank is lifted into the hydrolysis acidification tank by a pump, and the pollutants in the wastewater are preliminarily treated by microorganisms in the hydrolysis acidification tank to degrade its concentration.
4. The effluent from the hydrolytic acidification tank enters the contact oxidation tank, and the biological filler is set up in the contact oxidation tank to serve as a place for the growth of microorganisms. The blast aeration is used to provide the oxygen required for the growth of microorganisms, and the mixing and stirring is played to make the wastewater fully contact with microorganisms.
5. The effluent of the contact oxidation tank enters the sedimentation tank, and the sludge in the effluent of the contact oxidation tank is separated from the wastewater by the separation of sludge and water, so as to reduce the concentration of suspended solids in the effluent and make it meet the discharge standard.
6. The effluent from the secondary sedimentation tank enters the contact disinfection tank, and the harmful bacteria in the wastewater are killed by adding disinfectant, so that the microbial index meets the discharge standard. The effluent is measured by the discharge port and discharged into the municipal sewage pipe network, and finally discharged into the water body after further treatment through the lower sewage treatment plant.
7. The sludge separated from the secondary sedimentation tank is partially returned to the hydrolysis acidification tank and the contact oxidation tank to supplement the lost sludge. The remaining sludge is discharged into the sludge tank and temporarily stored. After reaching a certain amount, disinfectant is added for disinfection and then transported for safe disposal.
