Filtering tank for quickly treating domestic sewage

Abstract

The invention relates to the technical field of energy conservation and environmental protection, and discloses a filtering tank for quickly treating domestic sewage. The filtering tank comprises a tank body, wherein a water inlet pipe is arranged at the upper part of the left end of the tank body, an observation port is arranged at the top of the tank body, a blow-off pipe is arranged at the right side of the tank body, a base is arranged below the tank body, a water outlet pipe is arranged at the bottom of the tank body, a driving pipe is arranged in the center of the tank body, a lead screwis arranged in the driving pipe, the left end of the driving pipe is fixedly connected with a sealing terminal, a gear at the left end of the sealing terminal is connected with an outer coupling shaft in a meshed mode, a sealing lining is arranged in the sealing terminal, and fan blades are arranged at the right end of the driving pipe. According to the filtering tank for quickly treating domestic sewage, the impeller is driven to rotate through force unloading of a cleaning spring, negative pressure is generated in a hollow frame, bacterial colonies on the filter screen are sucked into the middle of the tank body through a suction nozzle, cleaning of microorganisms attached to the filter screen is achieved, the filtering quality is guaranteed, corrosion of the filter screen is prevented,and the service life is shortened.

Description

technical field [0001] The invention relates to the technical field of energy saving and environmental protection, in particular to a filter tank for rapidly treating domestic sewage. Background technique [0002] Urban domestic sewage, especially domestic sewage without toilet flushing, has better water quality and higher organic matter content. Many uses of water in cities, such as cooling water, flushing water, construction water, irrigation water, etc., do not have high water quality requirements, and domestic sewage can be used by simply filtering and treating it. However, the existing domestic sewage treatment system lacks rough treatment of domestic sewage. equipment, or uniformly mix the domestic sewage from various communities and send it to the sewage treatment plant. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the present invention provides a filter tank for rapid treatment of domestic ...
