| titleOfInvention | Method and system for treating agricultural non-point source pollutants in hilly area by using multistage wetland |
| abstract | The invention discloses a method and a system for treating agricultural non-point source pollutants in hilly areas by using a multi-stage wetland, which comprises the following steps: A. designing and constructing a flow distribution facility and a multi-stage wetland (comprising a grit chamber and a drop sill); B. plant configuration of the ecological wetland; C. breeding fishes in the wetland; D. and (3) managing and maintaining the ecological wetland: 1) cutting and utilizing wetland plants; 2) dredging; 3) harvesting the fishes. The flow dividing facility is connected with a grit chamber through a flow guiding blind groove/pipe, the grit chamber is respectively connected with the flow guiding blind groove/pipe and a first-stage wetland, a third-stage wetland is respectively connected with a second-stage wetland and a fourth-stage wetland through an overflow groove, a total wetland water outlet is respectively connected with the fourth-stage wetland and a drainage groove, and the wetlands are connected through the overflow groove and a drop sill. The method has the advantages of low operation cost and simple operation, has excellent treatment effect on non-point source pollutants of nitrogen and phosphorus in small watershed or water collecting area units, and has good popularization and application prospects in subtropical hilly areas at the middle and lower reaches of Yangtze river. |
