Biological treatment method for blue-green algae

Abstract

A biological treatment method for blue-green algae is characterized by including firstly, mounting fences at the positions one meter away from the bank of a water area needing to be treated so as to form one or more treatment areas, wherein the fences can enable water flow between the treatment areas and non-treatment areas to be exchanged and flow normally; secondly, removing underwater organisms and plants in the water area of the treatment areas and in the treatment areas; thirdly, planting aquatic plants capable of absorbing blue-green alga nutrients and throwing aquatic animals capable of digesting and decomposing the blue-green algae in the cleaned treatment areas; fourthly, exchanging water bodies between the treatment areas and the nontreatment areas to enable the blue-green algae in the non-treatment areas not to enter the treatment area. The aquatic animals digest the blue-green algae to produce waste which is absorbed by the aquatic plants to form benign ecological biologic chain cycle, so that a great quantity of biological enzyme and beneficial algae are produced in the water bodies of the treatment areas and play a role in constraining blue-green alga growth; water quality of the whole water bodies can be restored under the action of cyclic action. The biological treatment method for the blue-green algae is simple, feasible and good in effect.

Description

technical field [0001] The invention relates to a water treatment technology, in particular to a blue-green algae treatment technology, in particular to a blue-green algae biological treatment method. Background technique [0002] As we all know, my country is one of the countries in the world where cyanobacteria blooms occur more seriously. For example, water bodies such as Taihu Lake, Chaohu Lake and Dianchi Lake often break out cyanobacteria blooms. After the water bloom phenomenon occurs, cyanobacteria produce toxins (MC for short). In addition to directly poisoning fish, humans and animals, MC is a strong carcinogen and an important cause of liver cancer, directly threatening human health and production. The decomposition of blue-green algae and their bacteria can cause hypoxia in the water body and destroy the normal food web, threatening the safety of drinking water. From the end of May to the beginning of June 2007, the incident of drinking water source polluted by ...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the existing blue-green algae management actively relies on mechanized salvage to cure the symptoms but not the root cause, while chemical treatment will cause damage and secondary pollution to water bodies, aquatic animals and plants, and to invent a method for using animals and plants to treat blue-green algae
