Description

Biochemical pond aeration pipe anti-clogging device Technical Field The application relates to the technical field of sewage treatment, in particular to an anti-blocking device for an aeration pipe of a biochemical tank. Background In the sewage treatment process, the aeration tank is a core biochemical reaction unit, and functions to provide dissolved oxygen necessary for metabolism for aerobic microorganisms by forcibly filling air or oxygen into sewage. The activated sludge formed by the microorganisms can efficiently adsorb, decompose and oxidize organic pollutants in the sewage, thereby achieving the purpose of purifying water quality. The aeration system is a key component of the aeration tank and is generally composed of an aeration main pipe, a branch pipe and a plurality of aeration heads (such as microporous aerators) arranged on the branch pipe. The surface of the aeration head is distributed with micron-sized pores, which has the function of dispersing air into tiny bubbles so as to increase the gas-liquid contact area, thereby improving the transfer efficiency of oxygen. The aeration effect directly determines the speed of biochemical reaction, sewage treatment efficiency and the running energy consumption of the system. However, during actual operation, the aeration system, in particular the aeration head, is subject to a serious risk of clogging. Because the high-concentration activated sludge mixed liquid continuously exists in the aeration tank, sludge flocs can naturally settle under the action of gravity, and the sludge can gradually invade and block aeration holes on an aeration head, so that the aeration resistance is increased, the oxygenation capacity is obviously reduced, and the energy consumption is rapidly increased.
