Eutrophicated river water quality purifying method and purifying device thereof

Abstract

The invention discloses an eutrophicated river water quality purifying method. The method comprises the following steps of: intercepting eutrophicated river into upstream, midstream and downstream parts; then conveying water of the upper part into an electrolyzing machine to be electrolyzed; then, discharging the electrolyzed water into the midstream part to be subjected to aeration treatment at the midstream part; and finally, flowing the water subjected to the aeration treatment to the downstream part. The eutrophicated river water quality purifying method adopts a method for firstly electrolyzing and secondly aerating, and can effectively inhibit the growth of algae in the water and an anaerobic reaction of a water body; an organic matter is decomposed, and total nitrogen, total phosphorus and chromaticity in the water are reduced and the odor is removed, so as to improve the river water quality and recover a water ecological system in a shorter time. The invention further discloses a river water quality purifying device, comprising a rubber dam, a water pump, the electrolyzing machine and an aeration device. The river water quality purifying device can be directly mounted in a river to directly purify river water; and the river does not need to be specially leaded to a pre-set structure to be treated, and the river water quality purifying device nearly does not change an environment, so that the influences to a natural environment are smaller.

Description

technical field [0001] The invention relates to a river water treatment technology, in particular to a purification method and device capable of effectively treating eutrophic rivers, and belongs to the field of environmental protection. Background technique [0002] The river system is one of the important ecosystems in nature, which has multiple functions such as water delivery, flood discharge, landscape, shipping and breeding. With my country's rapid industrialization, urbanization and the intensification of non-point source pollution, river pollution has become a serious environmental problem. Excessive pollutants such as oxygen-consuming organic matter, nitrogen, phosphorus, and toxic substances enter the river water body, destroying the function of the river and the balance of water ecology, exacerbating the shortage of water resources, and threatening the health of residents near the water area. According to the recently released "2010 China Environmental Status Bul...

AI Technical Summary

Problems solved by technology

[0007] The invention provides a purification method and a purification device for the water quality of eutrophic rivers with low process cost, strong adaptability to water quality and good continuous effect, and its purpose is to overcome the long purification period and poor effect of the prior art The defects of the deep eutrophication rivers improve the water quality, restore the water ecosystem, and realize the healthy and sustainable development of the river ecosystem.
