A water ecological restoration device and restoration method thereof

Abstract

The invention discloses a water ecological restoration device and a restoration method thereof, comprising a diversion tube with an open lower end, a bioremediation component fixed on the top of the diversion tube, positive ion filter components and negative ion filter components on both sides of the diversion tube; There is a water pump in the tube, and a positive electrode and a negative electrode are vertically arranged in the diversion tube, and a separator is arranged between the positive electrode and the negative electrode. There is a flocculant storage box, and there is a sensor outside the bottom of the diversion tube; the positive ion area is connected with the positive ion filter assembly, the negative ion area is connected with the negative ion filter assembly, the positive ion filter assembly and the negative ion filter assembly are connected with a confluence box, and the confluence box is connected with the biological The restoration components are connected; the first pipeline and the second pipeline are wound on the outside; the ends of the biological restoration components are fixed with several floating bodies. The invention provides a water ecological restoration device with high restoration efficiency and capable of simultaneously repairing heavy metal pollution and pollution with high nitrogen and phosphorus concentrations.

Description

Technical field [0001] The present invention relates to a water ecological technology, and particularly relates to a water-repair method and apparatus ecological restoration. Background technique [0002] Eutrophication is one of the major environmental problems facing humanity. Eutrophication mainly by a point source pollution sources of pollution and of nitrogen, phosphorus and other organic matter caused. Point source pollution is mainly due to my country's current municipal facilities is not perfect, the construction of urban sewage treatment plants still can not meet the needs of economic and social development, a large part of untreated sewage directly into rivers, lakes and the receiving water body, point source pollution caused by water containing a large amount of heavy metal contaminants; point source pollution primarily due to agriculture administration of nitrogen, phosphorus can not be fully utilized by the plant, with the receiving water runoff enters the precipitat...

AI Technical Summary

Problems solved by technology

Point source pollution is mainly due to the fact that the current municipal facilities in our country are not perfect, and the construction of urban sewage treatment plants cannot meet the needs of economic and social development. A large part of untreated sewage is directly discharged into receiving water bodies such as rivers and lakes. Point source pollution leads to a large amount of heavy metal pollutants in the water body; non-point source pollution is mainly due to the fact that the nitrogen and phosphorus fertilizers used in agriculture cannot be fully utilized by plants, and they enter the receiving water body with surface runoff during the precipitation process, causing nitrogen, phosphorus The concentration of organic matter increases, leading to eutrophication of the water body

[0003] In the process of water body restoration in the prior art, only the heavy metals in the water body or the concentration of nitrogen and phosphorus in the water body are repaired in a single way, and the restoration speed of this restoration method is slow and the restoration effect is not good
