Embodiment Construction
[0007] 1. Cut off pollution sources, and carry out interception treatment on all pollution sources in the river basin, including point sources and non-point sources. Point source control: ban all sewage outlets, transport industrial wastewater and domestic sewage to sewage treatment plants through pipelines, and discharge them after centralized treatment reaches the standard. For remote river courses, distributed integrated sewage treatment equipment can be used, and sewage treatment can be arranged at each large sewage discharge point before discharge. Non-point source control: increase the greening rate in the watershed, especially set up green areas on both sides of the river, plant trees, turf, etc. to absorb and intercept some pollutants, reduce the cement solidification of the ground, so that water can penetrate into the soil, and reduce the non-point source pollution load.
[0008] 2. For river bank reconstruction, in areas with suitable conditions, eliminate solidified...
