Composition for governing lakes and application thereof

Abstract

The invention discloses a composition for governing lakes and an application thereof, wherein the composition is composed of the following raw materials by the weight percentage: 15-25% of acrylic acid esters, 25-40% of acrylonitrile, and 35-50% of styrene. After microorganisms added into the composition are cured, the cured composition is added into the lakes and performs restoration treatment on the lakes, and a composed ecological revetment effectively enriches N, P and other nutrients and also promotes the growth of the microorganisms; the composition plays significant roles in restoring an aerobic ecological system of rivers and the lakes and improving the self purification capacity, is conducive to breeding habitat of tiny animals, fishes, insects and the like, can meet the requirements of ecological restoration, and is conducive to the increase of water body dissolved oxygen and the growth of aquatic organisms.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a composition for treating lakes and an application thereof. Background technique [0002] Lakes are important surface water resources that can be used in multiple functions. Among them, large lakes also have high functions such as irrigation, flood control, shipping, and breeding, and also play an important role in regulating climate. It can be seen that lakes are closely related to human survival and social development. Rational use of lake resources and protection of lake ecological environment are major issues for social and economic development. [0003] Lakes are closely related to human life and have been affected by human activities, especially in the densely populated eastern areas, where lakes are increasingly polluted. There are seven major problems in the ecological environment of Chinese lakes: sedimentation, water surface shrinkage, swa...

Problems solved by technology

[0004] At present, most urban river (lake) revetments in my country mainly consider their flood storage, flood discharge, and flood discharge functions, and adopt reinforced concrete structures or concrete block linings, which mainly have the following deficiencies: the slope protection is strong, blocking the ecological connection of water and soil, causing the river bank light bald, aquatic plants cannot grow; the river bank has no porous structure, and micro-animals, fish, insects, etc. cannot inhabit and reproduce; the concrete revetment is exposed to direct sunlight, and the surface temperature is higher than the actual temperature, especially the slope revetment makes the water layer on both sides of the river thin , aggravate the rise of water temperature, which is conducive to the growth and reproduction of algae, and is prone to "algae bloom"; the color of concrete revetment is monotonous, the structure is single, and the landscape effect is poor

This method returns the groundwater with good water quality to the upstream of the lake to supplement the lake water intake, improves the self-purification ability of the lake water body, and accelerates the consumption rate of pollutants inside the lake, but the operation is very complicated and requires a large amount of groundwater consumption, which is not conducive to environmental protection.
