Purification method and purification device of eutrophic river

Abstract

The invention discloses a purification method of a eutrophic river. The method comprises the following steps: firstly intercepting a eutrophic river into an upstream part and a downstream part; subsequently, sending water in the upstream part into an electrolysis machine for electrolysis; and discharging filtered water into the downstream part after being filtered. According to the invention, an electrolysis treatment method is adopted, thereby effectively restraining growth of algae in the river, decomposing organic matters, reducing total nitrogen, total phosphorus and chromaticity, eliminating odor, and finally improving water quality of the river within short time so that an ecological system is recovered. The invention further discloses a water quality purification device which mainly comprises a dam, a water pump, the electrolysis machine and a filter. The device can be directly operated at river banks to directly purify river water, is not required for specially introducing the river to a preset building for treatment, has barely change on the environment, thus having smaller influence on the natural environment; and in addition, the structure is simpler, and the production cost is lower, thus being suitable for large-scale popularization and application.

Description

technical field [0001] The invention relates to the field of ecological technology treatment, in particular to a purification device capable of effectively treating eutrophic rivers and a purification method thereof. 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 Bulletin", my country's ...
