Description

Technical Field

[0001] The utility model relates to a sewage treatment device, in particular to a sterilization and algae inhibition treatment device for circulating water of a domestic garbage incineration power plant. Background Art

[0002] In order to save water resources, domestic waste incineration power plants usually use circulating water as cooling water for waste incineration treatment. However, as the use time of circulating water increases, the circulating water in the circulating water pool is prone to breed bacteria, microorganisms and other pollutants, which is not conducive to subsequent use. Industrial circulating water generally uses chemical methods to sterilize and kill algae, which not only has high treatment costs, but also easily causes secondary pollution. Therefore, there are currently bactericidal and algae-inhibiting processors that use physical methods. The electrode components in them change the magnetic field in the circulating water, causing non-thermal effects on the bacteria in the water, causing the proteins and physiologically activated substances in the bacteria to mutate and die.

[0003] For example, CN 219098850 U discloses an industrial circulating water treatment device, including a treatment pool, a treatment chamber is provided inside the treatment pool, a reciprocating mechanism is provided on one side of the treatment pool, a connecting bracket is provided on the reciprocating mechanism, a bactericidal and algae-inhibiting processor is fixedly connected to the bottom end of the connecting bracket, and a diversion mechanism is provided on both sides of the bactericidal and algae-inhibiting processor, and the diversion mechanism includes two diversion covers, the tops of the two diversion covers are fixedly connected to drive covers, and the diversion shaft is rotatably connected inside the diversion cover. The device is intended to divert the water on both sides to the moving track of the bactericidal and algae-inhibiting processor by setting a diversion mechanism during the reciprocating movement of the bactericidal and algae-inhibiting processor, so that the circulating water can fully contact the bactericidal and algae-inhibiting processor and improve the treatment effect. However, there are still the following problems: there are many components and diversion components used to move the bactericidal and algae-inhibiting processor, and the failure rate is high.
