Tidal river self-purification type ecological restoration combined dam

Abstract

The invention relates to a tidal river self-purification type ecological restoration combined dam, wherein a water body ecology restoration zone comprises rubber dams, spur dikes, ecological reef groups, fixing tables and organism migration channels, wherein one end of the rubber dam is connected to a river bank through the fixing table, the other end of the rubber dam is connected to one side ofthe organism migration channel through the fixing table, and the spur dikes are arranged at the bent positions of the two sides of a river course, extend into the river course from the river banks andare sequentially arranged from the upstream to the downstream of the river course. According to the invention, by arranging the rubber dams, the reflux of tide water during tidal bulge is avoided, sothat the stable and low-flow-speed water area repairable environment is provided for the aquatic remediation area; by arranging the organism migration channels, the living habits of aquatic organismsare protected; the spur dike has interception and adsorption effects on nitrogen and phosphorus in the river way; and the ecological reef groups provide good hiding and breeding places for underwaterhabitats, planktons, fishes and the like, build and recover the local ecological environment of the river course, and increase the biological diversity.

Description

technical field [0001] The invention specifically relates to a self-purifying ecological restoration composite dam for tidal rivers. Background technique [0002] As tidal rivers are affected by ebb and flow and runoff, pollutants will flow back and forth in the river, staying for a long time, pollutants cannot be diffused in time, and easy to deposit, which not only affects the deterioration of the river water body, but also causes river sediment pollution. Most tidal rivers are located in watersheds where salty and fresh water alternate, and the accumulation of salinity has seriously affected the biodiversity of the watershed. Therefore, the pollution of tidal rivers is particularly serious in densely populated areas and areas with dense factories. The actual effects of various ecological treatment technologies currently on the market are not ideal, and this type of river course has become the focus and difficulty of treatment in the task of eliminating black and odor in b...

[0002] As tidal rivers are affected by ebb and flow and runoff, pollutants will flow back and forth in the river, staying for a long time, pollutants cannot be diffused in time, and easy to deposit, which not only affects the deterioration of the river water body, but also causes river sediment pollution. Most tidal rivers are located in river basins where salty and fresh water alternate, and the accumulation of salinity has seriously affected the biodiversity of the river basin. Therefore, in densely populated areas and areas with dense factories, the pollution of tidal rivers is particularly serious
