Method for restoring eutrophic water body

Abstract

The invention discloses a method for repairing an eutrophic water body. The method comprises the following steps: 1, preparing an eutrophic water body repairing agent from water, an oxygen release agent, biomass charcoal powder, a composite microbial agent, an alkaline agent and a binder; and 2, applying the eutrophic water body repairing agent to the eutrophic water body. The method for repairingthe eutrophic water body has the advantages of high removal rate, low cost, environmental friendliness and the like, and the eutrophic water body can be efficiently and durably repaired.

Description

technical field

[0001] The invention belongs to the field of water environment restoration, and in particular relates to a restoration method for eutrophic water bodies. Background technique

[0002] With the rapid development of industry and agriculture, a large amount of industrial wastewater containing nitrogen and phosphorus, domestic sewage, and even untreated sewage are directly discharged into rivers, causing eutrophication in some rivers. The eutrophication of water body is caused by the excess of nutrients (such as nitrogen, phosphorus, etc.) in the water body, which leads to the excessive proliferation of algae, the reduction of dissolved oxygen content in the water body, the massive death of aquatic organisms, and the deterioration of water quality. The eutrophication of water not only leads to the destruction of the river ecosystem, but also affects people's production and life. Therefore, the restoration of eutrophic water has become an urgent water environment ...
