Municipal sewage treatment filtering device

Abstract

The invention discloses a municipal sewage treatment filtering device which comprises a box body, a partition plate is fixed to the side wall of one end in the box body, a vertical plate is fixed to the upper end of the partition plate, an inclined plate is fixed to one side of the partition plate, an arc-shaped plate is fixed to one side of the inclined plate, and the arc-shaped plate is fixedly connected with the side wall of the other end in the box body. And a discharge mechanism is arranged on the arc-shaped plate. According to the municipal sewage treatment filtering device, sewage can be well filtered, impurities in the sewage can be reduced, the subsequent sewage filtering treatment effect can be improved, the impurities in the sewage can be conveniently cleaned and collected, centralized treatment of the impurities is facilitated, meanwhile, a large number of impurities can be effectively prevented from being attached to a filtering part, cleanliness of the filtering part is guaranteed, the service life of the filter is prolonged, the filtering efficiency and quality are guaranteed, meanwhile, flow diversion can be well carried out, closing and opening can be conveniently carried out according to needs, overhauling and maintenance can be sequentially carried out under the non-stop condition, and the filtering work quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a filter device for municipal sewage treatment. Background technique [0002] Municipal sewage usually includes domestic sewage, industrial wastewater and road rainwater, among which domestic sewage and road rainwater often carry a lot of sundries, and the sundries are of different sizes. [0003] In the related technologies of traditional municipal sewage treatment, it mainly includes the following steps: primary filtration, biochemical oxidation treatment, and secondary filtration. The primary filtration is mainly to separate the insoluble or insoluble impurities carried in the original municipal sewage from the sewage, which is usually completed by a grill machine. Then biochemical oxidation treatment is used to decompose the organic matter in the sewage and reduce the COD value in the sewage. Finally, through secondary filtration, the suspended solids produced by t...

Problems solved by technology

[0004] In order to better improve the treatment effect, it is necessary to ensure the quality of primary filtration. Existing equipment generally filters through a screen to remove debris. However, after a long period of use, the debris accumulates on the screen and blocks the filter holes. , leading to the inability to filter efficiently, and at the same time, long-term use will also cause a large amount of dirt to adhere to the equipment, affecting the use effect. Therefore, we propose a municipal sewage treatment filter device to solve the above problems
