Abstract

The invention discloses a suspending filter material having a trace element self-release function. The suspending filter material comprises polyurethane sponge, and a trace element releaser is embedded in the polyurethane sponge. The filter material is suitable for a biochemical function of a suspending rapid filter, has good intercepting and adsorbing effect on suspending pollutants and has goodmicrobial adhesion, bio-film formation and bio-film protection effect, thereby being capable of better playing a role in quick filtering and biochemical treating; the trace element releaser can provide needed trace elements for microorganisms to grow, so that microbial adhesion and bio-film formation are better facilitated.

Description

technical field [0001] The invention relates to a suspension type filter material with trace element self-releasing function. Background technique [0002] In rainy days in the combined drainage area, with the increase of rainfall, the rainwater runoff will increase accordingly. When the pipeline flow exceeds the conveying capacity of the intercepting main pipe, overflow will occur, and part of the mixed rainwater and sewage will pass through the overflow well or pumping station The overflow caused by discharge into the receiving water body is the combined sewer overflows (CSO). After urban point source pollution is gradually controlled, urban CSO, as a typical non-point source pollution, has become an important cause of water environment pollution and ecological system imbalance in cities around the world. If urban CSO is not controlled, the pollutants directly discharged into natural water bodies will Seriously damage the water quality of urban water bodies and affect the...
