Riverway in-situ purification and water storage system

Abstract

The invention discloses a riverway in-situ purification and water storage system, and relates to the technical field of environment protection. The riverway in-situ purification and water storage system comprises a shallow percolation dam, a front-dam water storage zone surface flow wetland system and a below-dam sunken ecological pond, the shallow percolation dam is arranged at the bottom of a channel of a riverway, and the width of the shallow percolation dam is the same as the width of the riverway; the front-dam water storage zone surface flow wetland system is arranged at the position, in front of the shallow percolation dam, in the riverway, and the below-dam sunken ecological pond is arranged behind the shallow percolation dam and below the elevation of the bottom of the channel of the riverway; and the shallow percolation dam comprises a water blocking layer and a percolation layer arranged on the water blocking layer. Certain river water can be blocked so that water can be stored in the front-dam water storage zone surface flow wetland system, the water resource inventory is increased, and a power-free water allocation mechanism can be provided for the below-dam sunken ecological pond; and meanwhile, coming water can be subject to initial sedimentation, filtering and purification, the below-dam sunken ecological pond is built below the elevation of the bottom of the channel and has no influences on drawing off floodwater, and the purification effect and the water storage function are achieved.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a river channel in-situ purification and water storage system. Background technique [0002] At present, under the background of sponge city construction, the treatment of black and smelly rivers has been fully launched all over the country. For water-scarce polluted rivers, although land-based pollution can be controlled by various means, the pollution load entering the river can be reduced to a certain extent, which has certain significance for eliminating black and odorous rivers and improving water quality. However, there are still many pollutants that will enter the river through various channels to pollute the river water and cause new pollution. However, when the water volume of the river is small, there is no external clean water to supplement, and the self-purification ability is weak, the pollution and purification of the river itself must be strengthen...

Problems solved by technology

But its disadvantage is that if the weir is built too high, it will have an adverse effect on flood discharge, and it has little effect on water purification, so it is difficult to meet the needs of in-situ purification of river sewage

However, if the river sewage is transported to the outside of the river for treatment, it will occupy a large area and consume high energy consumption. Therefore, it is necessary to provide an in-situ purification and purification of the river that can meet the flood discharge requirements and has energy-saving and land-saving benefits. water storage system
