Problems solved by technology

Nutrient salt control alone is not effective. It ignores the nutrient salt cycle in the lake and the interaction between organisms, and it is difficult to completely control the internal cycle and external source pollution, but the control of nutrient salt is the prerequisite for the treatment of eutrophication. Exogenous point source pollution is not completely cut off, and exogenous non-point source pollution is not properly controlled. Even the best measures to control eutrophication wil

Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0030]Ecosystem degradation must also be managed with an ecological approach. The apparent characteristic of eutrophic algae-type water body is the massive reproduction of phytoplankton, which will lead to catastrophic consequences such as deterioration of water quality, decline of water body function, and death of aquatic organisms. Water body restoration is not only a matter of simply removing algae to solve surface problems, but also must solve the fundamental problem - the ecological restoration of damaged water bodies. The purpose of water ecosystem restoration is to reproduce a natural, self-sustaining and regulating ecosystem so that it forms a complete unity with the natural landscape where it is located. Based on the basic principle of ecology, the present invention...

Abstract

The invention discloses a method for purifying an eutrophic water body by using aquatic animals, plants and microorganisms; aquatic plankton is cultivated beforehand, and the following steps are carried out: a predetermined number of the cultivated aquatic plankton is put in a target water domain; the water body is kept in a transparent state as the aquatic plankton eat blue-green algae in the target water domain and restrain the regrowth of the blue-green algae; submerged plants in the target water domain are recovered to keep the water body in a stable clear state; engonus aquatic animals are poured in the target water domain to reinforce the water body biology diversity; and the ecologic stability of the water body at present is maintained. In the method for purifying the eutrophic water body by using the aquatic animals, plants and microorganisms, the ecologic method is used for forming an excellent water ecosystem to recover the service functions of the original ecosystem.

Description

technical field [0001] The invention relates to a method for purifying eutrophic water body, in particular to a method for purifying eutrophic water body by using aquatic animals, plants and microorganisms. Background technique [0002] Now, eutrophication and the resulting algae blooms and the degradation of water ecosystem not only restrict the availability of lake resources, but also directly affect the healthy survival of human beings and the sustainable development of social economy. major environmental problems, and the restoration of degraded water ecosystems is also a major global problem. [0003] So far, there has been no mature technology that can be promoted on a large scale. The ecosystem is a complex and open giant system. There are complex linear and nonlinear connections between a large number of constituent units of the system, which can show structures at different levels. and functional diversity, self-organization and complexity. Therefore, it is diffic...
