Geological material-based rainwater quality treatment system

Abstract

The invention provides a geological material-based rainwater quality treatment system. The geological material-based rainwater quality treatment system at least comprises a desilting sand basin, a filtering basin, an anti-plugging monitoring unit, and a water quality monitoring unit, wherein a water inlet pipe, a guide channel and a sewage pipe net inlet are at least arranged in the desilting sand basin, the filtering basin and the desilting sand basin are communicated by a reinforced concrete hollow retaining wall arranged, a filler is filled in the filtering basin, and the anti-plugging monitoring unit consists of a flow sensor, an air compressor and a water pump A; and the water quality monitoring unit consists of a water quality monitor for detecting parameters of the water quality, and a water pump B, and the water pump B is connected with a water outlet of the filtering basin. According to the geological material-based rainwater quality treatment system, the deficiencies occurring in the traditional water quality treatment engineering can be solved; and a new mineral filtering material is selected, and a backwash system and the water quality monitoring unit are also arranged, so that the rainwater quality can be comprehensively improved from a plurality of aspects.

Description

technical field [0001] The invention provides a rainwater quality treatment system based on geological materials, which is used for solving the water quality treatment problem of urban runoff rainwater and belongs to the field of environmental geology research. Background technique [0002] In recent years, with the continuous acceleration of China's urbanization process, the contradiction between population and natural resources has become increasingly prominent, and the problem of insufficient water resources is particularly serious. In order to avoid unrestrained exploitation and utilization of limited groundwater, scholars at home and abroad propose to collect and utilize rainwater resources. However, after investigation and research, it is found that the water quality of urban rainwater runoff is very poor, and the pollution level of initial runoff is even higher than that of urban sewage. In addition to the influence of air quality, the most important influencing fact...

Problems solved by technology

One is the coagulant method. This method is effective in removing heavy metals, phosphorus, and chroma, but the removal effect on ammonia nitrogen and organic matter is not ideal. In addition, the addition of various flocculants is not easy to separate from water at the bottom, which will cause secondary pollution. Secondary pollution; secondly, biochemical method has a good removal effect on organic pollutants, ammonia nitrogen and phosphorus, but it has a good removal effect on COD Cr The removal rate is low, the decolorization effect is poor, and a large amount of sludge will still be generated, causing blockage and secondary environmental pollution
