Method and device for cleaning filler accumulated on intercepting net of water outlet of aerobic tank

Abstract

The invention relates to a method and device for cleaning filler accumulated on an intercepting net of a water outlet of an aerobic tank and belongs to the technical field of sewage treatment. The device is characterized in that an output end of a hoisting mechanism (1) downward penetrates through a bracket seat (2) to be connected with a hoisting rod (3) which is vertically arranged; the hoistingrod (3) slides up and down in a shaft sleeve of a shaft sleeve seat I (4) and a shaft sleeve seat II (18); a scraping plate frame (5) is arranged on the hoisting rod (3) between the shaft sleeve seatI (4) and the shaft sleeve seat II (18); the scraping plate frame (5) is provided with a scraping plate (6); the scraping plate (6) is matched with an intercepting net surface of an intercepting netdevice (7). According to the method and the device, provided by the invention, the electric hoisting mechanism rotates and moves frontward and backward and a scraping plate assembly moves up and down,so that the filler accumulated on the intercepting net of the water outlet of the aerobic tank can be effectively scraped off; the device is simple and reasonable in structure, good in utilization effect, low in cost, simple in processing and manufacturing and stable to operate.

Description

technical field [0001] The invention relates to a method and a device for cleaning fillers accumulated on a blocking net at a water outlet of an aerobic pool, and belongs to the technical field of sewage treatment. Background technique [0002] The MBBR filler in the aerobic tank must be fully in contact with the sewage to improve the use efficiency of the MBBR filler. The water outlet in the aerobic tank is equipped with a blocking device to prevent the outflow of the MBBR filler in the aerobic tank, and the MBBR filler follows the water flow , It is easy to accumulate on the surface of the blocking device at the inlet and outlet of the aerobic pool, and squeeze each other. The above-mentioned problems are firstly not conducive to the passage of water flow. If a certain water flow is required, then a larger outlet of the aerobic tank must be opened, and the corresponding project cost will be higher; the more important thing is that the MBBR filler accumulates in the well. ...

AI Technical Summary

Problems solved by technology

The above-mentioned problems are firstly not conducive to the passage of water flow. If a certain water flow is required, then a larger outlet of the aerobic tank must be opened, and the corresponding project cost will be higher; the more important thing is that the MBBR filler accumulates in the well. The blocking device at the outlet of the oxygen pool cannot be in good contact with the sewage, the speed of film formation is slow, and the amount of biological adhesion is small, which is not conducive to the growth of bacteria. The corresponding organic matter is decomposed into inorganic matter, and the ability to remove pollutants is greatly reduced.
