Problems solved by technology

Its disadvantages are: (1) It occupies a large area; (2) The sludge or mixed liquid needs to be reflowed with external power, which leads to high energy consumption; (3) The sludge concentration of the process is low and the activity is poor, so the ability to resist impact load is weak and the quality of the effluent water is unstable.
In addition, if the conventional aeration method is adopted, fans are required to provide air source, and an additional fan room is required to increase energy consumption

Embodiment 1

[0041] The average raw water quality of domestic sewage in a township is: COD (Chemical Oxygen Demand, chemical oxygen demand) 225mg / L (mg per liter), ammonia nitrogen 30mg / L, total nitrogen 40mg / L, total phosphorus 2.0mg / L, collected After the pool is collected, adopt the anoxic aerobic precipitation integrated sewage treatment system 1 of the vertical partition of the application, the sewage enters the anoxic reaction zone through the raw water distribution pipe, and the agitator in the anoxic zone located in the anoxic reaction zone provides stirring power, and the water level Gradually ascend into the aerobic reaction zone. The submersible aerator in the aerobic reaction zone sucks in air through the negative pressure suction pipe protruding from the water surface, and then releases the dissolved air water through the release tube at the bottom. On the one hand, it provides the oxygen needed for the aerobic reaction. Oxygen, on the other hand, provides the power of air-lift...

Embodiment 2

[0043] The domestic sewage in a highway service area, the raw water quality is: COD 280mg / L, ammonia nitrogen 60mg / L, total nitrogen 80mg / L, total phosphorus 4.0mg / L, using the vertical partition anoxic aerobic precipitation integrated sewage of this application Treatment system 1, the sewage enters the anoxic reaction zone through the raw water distribution pipe, the agitator in the anoxic zone located in the anoxic reaction zone provides stirring power, the water level gradually rises into the aerobic reaction zone, and the submersible aerator in the aerobic reaction zone The negative pressure suction pipe on the water surface sucks in air, and then releases the dissolved air water through the release pipe at the bottom. On the one hand, it provides the oxygen required for the aerobic reaction, and on the other hand, it provides the power of air-lift circulation. The nitrifying liquid in the upper part of the aerobic reaction zone After being collected through the nitrificati...

Abstract

The utility model discloses a stirring and aerating integrated device which comprises a motor and a stirrer linked with an output shaft of the motor through a connecting rod, and further comprises an aerator arranged on the connecting rod in a sleeving manner, and the aerator is arranged between the motor and the stirrer. The motor, the aerator and the stirrer are connected into the integrated device through the connecting rod, so that the assembly process of the equipment is simplified, the content space of sewage treatment equipment using the integrated device is increased, and the sewage treatment efficiency is improved. According to the vertically-partitioned anoxic and aerobic precipitation integrated sewage treatment system, the stirring and aeration integrated device is adopted, the stirring and aeration integrated device is installed through the supporting beam stretching across the tank body, meanwhile, the supporting beam serves as a partition marker of the anoxic reaction zone and the aerobic reaction zone, the structure is simple, and installation is easy.

Description

technical field [0001] The present application relates to the technical field of water treatment, in particular to a vertically partitioned anoxic-aerobic-sedimentation integrated sewage treatment system, and an integrated agitation and aeration device thereof. Background technique [0002] At present, the sewage treatment process using biochemical technology, most of the structure is still in the plane direction to realize the function of each process treatment unit. Its disadvantages are: (1) It occupies a large area; (2) The sludge or mixed liquid needs to be reflowed with external power, which leads to high energy consumption; (3) The sludge concentration of the process is low and the activity is poor, so the ability to resist impact load is weak and the effluent quality is unstable. In addition, if the conventional aeration method is adopted, fans are required to provide air source, and an additional fan room is required to increase energy consumption. Contents of the...
