Water ecology restoration device and restoration method thereof

Abstract

The invention discloses a water ecology restoration device and a restoration method thereof. The water ecological restoration device comprises a flow guide pipe with an opening in the lower end, a biological restoration assembly is fixed to the top of the flow guide pipe, a positive ion filtering assembly and a negative ion filtering assembly are arranged on the two sides of the flow guide pipe, a water pump is arranged in the flow guide pipe, a positive electrode and a negative electrode are vertically arranged in the flow guide pipe, a partition plate is arranged between the positive electrode and the negative electrode and divides the flow guide pipe into a negative ion area and a positive ion area, the bottoms of the positive electrode and the negative electrode communicate with a flocculant storage box, a sensor is arranged on the outer side of the bottom of the flow guide pipe, the positive ion area communicates with the positive ion filtering assembly, the negative ion area communicates with the negative ion filtering assembly, the positive ion filtering assembly and the negative ion filtering assembly communicate with a combiner box, the combiner box communicates with a bioremediation assembly, a first pipeline and a second pipeline are wound on the outer side, and a plurality of floating bodies are fixed to the end of the bioremediation assembly. The invention provides the water ecological restoration device which is high in restoration efficiency and can simultaneously restore heavy metal pollution and pollution with high nitrogen and phosphorus concentration.

Description

technical field [0001] The invention relates to the technical field of water ecology, in particular to a water ecology restoration device and a restoration method thereof. Background technique [0002] Eutrophication of water body is one of the main environmental problems faced by human beings. Eutrophication of water body is mainly caused by organic matters such as nitrogen and phosphorus in point source pollution and non-point source pollution. 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 i...

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
