Method for constructing lake and reservoir water ecosystem

Abstract

The invention relates to a method for constructing a lake and reservoir water ecological system. The method comprises the following steps: S1, constructing water ecological basic conditions and improving water quality, wherein in water ecological basic condition construction, a nano hydrogen storage-oxygen storage material and a catalytic material are placed in a slow release box, the slow release box is placed in a lake and reservoir bottom layer area and carries hydroxide ions in the natural environment to an underlying water body and a bottom layer, and the slow-release box is also filled with a catalytic material, so that the enzyme activity and the microbial activity in the water body are activated; and S2, constructing a water ecological system, wherein a vertical structure is formed through aquatic plant construction, aquatic animal construction and microorganism construction, so that an aquatic plant community, an aquatic animal community and a microorganism community are formed, and the aquatic plant construction comprises submerged plant construction, emergent aquatic plant construction and floating-leaved plant construction. The method has the advantages that sludge degradation is promoted, accelerated conversion of nutritive salt substances is promoted, and natural purification can be achieved.

Description

technical field [0001] The utility model relates to the technical field of lake and reservoir ecology, in particular to a method for constructing a lake and reservoir water ecosystem. Background technique [0002] As a unique resource closely related to human survival and development, lakes play a huge role in water supply, flood control, shipping, breeding, tourism and maintaining regional ecological balance. At present, due to the super-intensive development of river basins and the super-intensive utilization of lake resources, a series of problems have been caused, such as deterioration of water environment, shortage of water resources, and frequent occurrence of water disasters. [0003] The specific realization is: the technology of water quality improvement and treatment mainly focuses on the research and application of single technologies such as dredging, water diversion and flushing, aeration and oxygenation, chemical flocculation, and biological purification.
