Ecological bank protection module and system with initial rain purifying function

Abstract

The invention discloses an ecological bank protection module and system with an initial rain purifying function. The ecological bank protection module comprises an upper plant planting pool, a purifying pool arranged below the upper plant planting pool and a lower plant planting pol arranged on one side of the bottom of the purifying pool. The ecological bank protection system is formed by connecting the multiple ecological bank protection modules in series. The ecological bank protection module and system are simple in structure and convenient to assemble, demount, operation and maintenance management is convenient, the ecological bank protection module and system are applied to village and town regions incomplete in rainwater pipe network building, initial rainwater pollution can be effectively purified, and the bank protection function is achieved; and power is not needed, and a chemical agent does not need to be added.

Description

technical field [0001] The invention relates to the technical field of treatment of first rain pollutants, in particular to an ecological revetment module and system with the function of first rain purification. Background technique [0002] In the existing technology, interception wells, initial rain storage tanks and sponge facilities are usually used to separate or purify the pollutants in the initial rainwater, but the drainage pipe network in some villages and towns is still not perfect, or only the sewage pipe network is built but not In areas with imperfect rainwater pipe networks, if there is not enough space or the above-mentioned primary rain separation or purification facilities cannot be rebuilt in these areas, the initial rainwater will be directly discharged into the river through surface runoff without treatment, and then cause pollution to the river. [0003] For villages and towns where the rainwater pipe network is not perfect, it is necessary to develop an...
