Description
Technical Field
The invention relates to the technical field of sewage treatment equipment, in particular to a submersible water impeller for treating oxidation ditch membrane organisms.
Background
An Oxidation Ditch process (Oxidation Ditch process) is a deformation process based on activated sludge, and has the advantages of good and stable effluent quality, low excess sludge yield, simple operation management and the like. It is an activated sludge treatment structure with low organic load and long retention time, and is an innovative technology of an activated sludge method. Compared with other sewage treatment processes, the oxidation ditch has the advantages of low cost, simple and convenient operation, low maintenance cost, great diluting capacity on high-concentration wastewater and the like, so that the effluent quality is better. The membrane bioreactor is mainly a sewage treatment process for intercepting activated sludge and macromolecular organic matters in water by utilizing membrane separation equipment. In the prior art, the oxidation ditch-membrane bioreactor combining the oxidation ditch and the membrane biological is mainly composed of an annular ditch body, an aeration device, a plug flow device and a flat membrane component, wherein the plug flow device is used as a core mechanical device of the oxidation ditch-membrane biological treatment process and is one of key factors influencing the efficiency, power consumption and stability of the oxidation ditch-membrane biological treatment process. The plug flow device mainly has four functions in the oxidation ditch-membrane biological treatment process: 1. the sludge is prevented from silting under the stirring action; 2. fully mixing and contacting the organic pollutants, the activated sludge and the dissolved oxygen in the mixed solution; 3. when the paddle is placed on the water surface, oxygen in the air can be dissolved in the water; 4. the water flow is pushed to flow in the whole reactor at a certain flow speed (not less than 0.25m/s) in an oxidation ditch, thereby not only ensuring the hydraulics condition of the whole system, but also having a certain scouring effect on the membrane module. The efficient plug flow device has important significance for ensuring the high-load operation of the oxidation ditch membrane bioreactor and the prevention and treatment of sludge activity and membrane pollution.
In order to research the application value of the novel sewage treatment process in practical engineering, research institutes such as colleges and universities and research institutes have developed sewage treatment equipment combining an oxidation ditch and a membrane bioreactor, and the principle is to combine an activated sludge method of the oxidation ditch with a membrane filtration treatment method of the membrane bioreactor. Because the technology is in the research and development stage at present and is not put into commercial use, the oxidation ditch-membrane bioreactor in a laboratory is generally a micro device, the existing plug flow device cannot be put into the oxidation ditch membrane bioreactor in the laboratory due to the overlarge volume, and the existing plug flow device has a complex structure and high cost and can greatly improve the experimental cost. Although the wave-making pump can simulate a plug flow device in an oxidation ditch-membrane bioreactor, the plug flow power is too small, the motor generates heat seriously, heat is transferred into water, the temperature of sludge is increased, and the accuracy degree of an experiment is further influenced.
