Four Roles of Stamp Submersible Mixer in Sewage Treatment.
1. Carry out hydraulic circulation: the stamping submersible mixer only needs to provide the necessary circulating flow rate in the anaerobic tank, anoxic tank and oxidation ditch and other pools to keep the mixed liquid in the pool in a suspended state, so that the microorganisms are in full contact with the substrate, and the energy input by the agitator forms a continuous circulating water flow, which can not only effectively keep the mixed liquid suspended, but also because the flow rate of the circulating water flow in the pool is usually dozens of times higher than the inlet water flow, or even hundreds of times, so that the water flow in the pool has a huge dilution and homogenization capacity. As a result, the reactor has excellent process characteristics that can withstand shock loads.
2. Improve oxygen transfer efficiency: aeration is the basic means to maintain the normal metabolism of aerobic microorganisms, and the oxygen transfer efficiency of the underwater aeration system is directly related to the water depth. In the aeration tank, a stamping submersible mixer is used to design the aeration tank into the above-mentioned continuous circulating flow tank type, which will change the path of "bubbles" released by the aeration head and increase under the action of circulating flow rate"oxygen transfer water depth" to improve oxygen transfer efficiency.
3. Convenient grid and segmented processing: when the volume of a single grid pool is small, each grid can be designed as a square plane or a circular plane, and the stamping submersible mixer can be placed in each grid.
4. Improve water quality. Improvement of water quality In many polluted water bodies and advanced treatment ponds used for sewage treatment, the problems of deep water, sluggish water flow, and reoxygenation on the surface of the water body cannot ensure the dissolved oxygen requirements of the deep water area, a stamped submersible mixer can be set up for "artificial respiration" to reoxygenate the deep water area and improve the water quality of the entire water body. This "artificial respiration" technique is a simple and effective means of improving water quality.
