Problems solved by technology

[0007] Due to the constraints of external conditions, the ecological restoration of various types of water bodies in deep water areas has not been effective. Moreover, because the water body is too deep, higher submerged plants cannot grow, which greatly slows down the process of ecological reconstruction in deep water areas.

Abstract

The invention discloses a method for improving water quality in deepwater areas of lakes and reservoirs and controlling cyanobacterial bloom through artificial biological carriers.The method includes the steps that A, areas are selected, wherein locations where water surface operation is easy and wind and wave avoidance is achieved are selected as construction points; B, a water surface floating platform basic framework is built, wherein a framework of a water surface floating platform is built on the bank; C, the water surface floating platform is fixed, wherein the water surface floating platform is fixed by tying underwater weights through ropes, and the parts, needed during water level raising, of the ropes are reserved; D, biological carrier materials are preprocessed, wherein the biological carrier materials are hung on nylon ropes 20 mm thick at the interval of 16 cm on the bank, and the length of the nylon ropes is the same as the internal length of the water surface floating platform.The method has high ecological benefits, is obvious in effect, free of pollution, high in continuity, good in repeatability and suitable for various kinds of water ecological repair and cyanobacterial bloom control, and provides favorable conditions for ecological reconstruction of eutrophication reservoir bays.

Description

technical field [0001] The invention relates to the technical field of improving water quality in deep water areas of water bodies and controlling cyanobacteria blooms, and more specifically relates to a method for controlling cyanobacteria blooms by using artificial biological carriers to improve water quality in deep water areas of lakes and reservoirs. Artificial closed eutrophic water body. Background technique [0002] With the development of economy and the surge of population, a series of ecological and environmental problems have been caused, which highlights the contradiction between human needs and natural environment. Among them, water pollution has a wide range of impacts, great harm, and difficulty in recovery. In order to utilize natural resources sustainably, it is particularly important to solve water pollution. [0003] Biofilm is an actively growing and developing single or mixed population of microorganisms, such as sessile bacteria, protozoa, fungi and ...
