Capping and algae removal and foreign matter falling prevention device of biological filter of sewage treatment plant

Abstract

The invention discloses a capping and algae removal and foreign matter falling prevention device of a biological filter of a sewage treatment plant. The capping and algae removal and foreign matter falling prevention device comprises a winding roller and a limiting clamping pipe, wherein a front-end rotary shaft and a rear-end rotary shaft of the winding roller are fixedly connected with inner rings of upper-end bearings of two supporting plates respectively; end parts of two adjacent connecting rods are in sliding connection with clamping grooves formed in left and right ends of connecting parts respectively; the two adjacent connecting parts are arranged in a staggered manner; the connecting parts are used for keeping separation cloth between the two adjacent connecting rods straight andupright all the time, so that a condition that the separation cloth is bent and is in contact with water in the biological filter is prevented; a reflection layer of the separation cloth is used forreflecting sunlight and the sunlight cannot irradiate water in the biological filter; the growth of alga in the biological filter and the evaporation of water in the biological filter are avoided; a waterproof layer is used for preventing rainwater from falling into the biological filter so that the normal work of the biological filter is ensured; and a supporting layer is used for improving firmdegree of the separation cloth so that a condition that large-mass foreign matters fall into the biological filter is effectively prevented.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a device for removing algae and preventing foreign matter from falling into a biological filter tank of a sewage treatment plant. Background technique [0002] During the daily operation and management of the sewage treatment plant, it was found that the sewage treated by the biofilter still contains a certain concentration of organic matter, nitrogen, phosphorus and other nutrients needed for plant growth. Since there is no cover above the biofilter, it is directly exposed to sunlight, which provides an environment for the growth of algae, especially in summer. Algae will block the aeration head, resulting in increased energy consumption and affecting the treatment effect of the biological filter. Most of the existing technologies use manual cleaning. Workers need to hold high-pressure water guns to enter the filter tank to operate, which has great safety hazards. In a...

Algae will block the aeration head, resulting in increased energy consumption and affecting the treatment effect of the biological filter

Most of the existing technologies use manual cleaning. Workers need to hold high-pressure water guns to enter the filter tank to operate, which has great safety hazards. In addition, algae grow rapidly in summer, and there are problems such as high cleaning frequency, heavy workload, and incomplete cleaning. It has a great impact on the normal operation of the biofilter; and debris in the biofilter often falls into the pool, affecting the water quality of the biofilter
