Problems solved by technology

[0004] Although the existing technology for the treatment of eutrophication of lake water can achieve certain effects, due to the destruction of the original ecosystem and the lack of biodiversity, the impact of the lake water system on the external environment lacks buffering capacity. Therefore, the lake The treatment effect of the water body is difficult to maintain, and eutrophication pollution is prone to occur again

Embodiment 1

[0033] Example 1: Treatment of Landscape Lake of Dongguan Institute of Technology

[0034] Landscape Lake of Dongguan Institute of Technology, located in Dongguan Institute of Technology, with a total water volume of 3400m 3 , the lake water was yellowish-brown before the treatment, the lake water transparency was low, and had peculiar smell, and some indicators met the V-class standard for surface water inferiority.

[0035] According to the water quality and water quantity characteristics of the lake, after investigation and analysis, the lake water was treated with the technology of compound microbial bacterial agent treatment of lake water starting from May 1, 2008. A large amount of high-concentration composite bacterial agents are added, and the ratio of the composite bacterial agents is: photosynthetic bacteria, Bacillus subtilis, nitrifying bacteria, lactic acid bacteria, and yeast in weight ratios: 20:30:25:15:10 . The feeding ratio of the compound bacterial agent i...

Abstract

The invention provides a method for restoring ecology in a water body in a lake, which comprises the following steps: (1) detecting the pollution indexes of the water body in the lake; (2) putting an additive which is one or a combination of amino acid, minor elements, vitamin, lipids, purine and pyrimidine; (3) putting a composite microbial agent in a water body in an amount of 1 to 9 ppm; (4) allowing the composite microbial agent to transfer, covert and degrade substances in the water body in the lake; (5) putting aquaticanimals and / or planting plants in the lake; and (6) detecting the pollution indexes of the water body in the lake. The composite microbial agent comprises photosynthetic bacteria, bacillus subtilis, nitrobacteria, lactic acid bacteria and yeasts. The method for restoring ecology in water body in lake restores the biological diversification in the water bodies, subjected to eutrophicationin treatment, in the lakes, restore the ecology radically, and has the characteristics of long-lasting effect, low cost and simple use.

Description

technical field [0001] The invention relates to the technical field of ecological treatment, in particular to a lake water ecological restoration method. Background technique [0002] According to relevant data, among the large freshwater lakes in my country, Dianchi Lake, Taihu Lake, Chaohu Lake, and Hongze Lake have reached the level of eutrophication, while Poyang Lake and Dongting Lake are currently in the transition stage to eutrophication. The deterioration of lake water quality is mainly caused by the enrichment of a large number of nutrients imported from the outside world in the water body. [0003] At present, the restoration of ecosystems is mainly through the control of endogenous and exogenous nutrients. The control of endogenous nutrients is mainly divided into engineering measures, chemical methods, bioaugmentation methods, etc. Engineering measures mainly include: water diversion dilution, sediment dredging, sediment covering, etc.; chemical methods mainly ...
