Problems solved by technology

At present, non-point source pollution enters the water body through runoff, and a large number of river courses adopt the form of hard channelized revetment or soil natural revetment. The ability is effective. Under the complex situation of non-point source pollution, the eutrophication of water body is becoming more and more serious, and the trend of water body deterioration is obvious.

Description

technical field [0001] The invention relates to the technical field of lake water ecological restoration, in particular to a multi-domain composite initial rainwater collection and purification comprehensive ecological management system. Background technique [0002] Water environment governance is a major issue facing the environment today. For a long time, people have been exploring ways of water body governance and analyzing the causes of water environment deterioration. At present, according to research and practice at home and abroad, the main pollution sources that cause water body deterioration are point source pollution and Non-point source pollution, point source pollution and non-point source pollution are also the main direction of environmental governance. With the strengthening of the control of point source pollutants, the control of non-point source pollutants is becoming more and more important. [0003] Non-point source pollution refers to dissolved and sol...
