A kind of ecological matrix of hard bottom shallow water lake and its preparation method and substrate improvement method

Abstract

The invention discloses an ecological substrate of a shallow lake with a hard bottom, a preparation method and a method for improving the substrate, which are made of clay, environment-friendly ceramic filter balls and bentonite. Steps: 1) Select clay, environmentally friendly ceramic filter balls and bentonite as raw materials for substrate improvement; 2) Soak the environmentally friendly ceramic filter balls in dilute hydrochloric acid, wash with water until neutral, and dry; 3) Soak the bentonite in Sodium carbonate solution, stirred, and placed in a muffle furnace for roasting; 4) Mix clay, treated environmental protection ceramic filter balls and bentonite to make a substrate improvement ecological matrix material. A method for improving the substrate of a shallow lake with hard substrate, the steps of: a) setting bamboo sticks in the substrate improvement area of ​​the lake bottom to improve substrate diffusion and loss; b) sprinkling ecological substrate materials on the lake surface into the lake bottom; c) planting submerged plants Manage and maintain submerged plants in the base improvement area. The method is simple and easy to operate, and effectively solves the problems that submerged plants are difficult to root and easy to float in hard-bottom lakes.

Description

technical field [0001] The invention belongs to the technical field of ecological restoration of lakes, and more specifically relates to a substrate-improved ecological matrix material for hard-bottom eutrophic shallow-water lakes, and also relates to a preparation of a substrate-improved ecological matrix material for hard-bottom eutrophic shallow-water lakes The method also relates to a base improvement method for shallow lakes with hard-bottom eutrophication, which can be applied to ecological restoration projects for hard-bottom eutrophic lakes. Background technique [0002] The bioremediation technology of eutrophic shallow lakes is an emerging environmental biotechnology in recent years, and has been applied in lake restoration projects at home and abroad. The planting and restoration technology of submerged plants is the key technology of ecological restoration projects, and the use of aquatic macrophytes to restore water and sediment pollution is one of the effective...

Problems solved by technology

[0006] Another object of the present invention is to provide a substrate improvement method for eutrophic shallow lakes with hard substrates. The method is easy to operate and can improve the living environment of hard substrates in the demonstration area, making it suitable for the growth of submerged plants and effectively Solve the problems of difficult rooting and easy floating of submerged plants in hard-bottomed lakes. At the same time, improving the substrate can in-situ absorb and accelerate the mineralization of pollutants such as sediment organic matter, which is conducive to the restoration of the ecological environment of the water area and accelerates the restoration of the ecosystem. and build
