Algae-controlling and water-purifying biocenosis

Abstract

The invention discloses an algae-controlling and water-purifying biocenosis, relates to a composition, types and an action method of an algae-controlling and water-purifying biotechnological product and belongs to the field of blue-algae governance of environmental-friendly water treatment. The algae-controlling and water-purifying biocenosis comprises one or more marine fishes and one or more freshwater aquatic animals and is constructed in an inland freshwater area environment by virtue of an artificial method. The algae-controlling and water-purifying biocenosis comprises algae-controlling and water-purifying key biological specie adopting marine fishes as a characteristic and a key biological chain adopting marine fishes as a characteristic is constructed, the algae-controlling and water-purifying effects are compounded and the problem of blue-algae inundation is solved in an in-situ manner, so that no risk of biological invasion is caused, the diversities of aquatic organisms in a freshwater area can be increased, detritus substances in the sediment can be recycled, the water can be purified, the high-class aquatic protein can be increased and the economic and social values are also increased; the algae-controlling and water-purifying biocenosis has the advantages of high purification treatment efficiency and good, lasting and stable algae-controlling effect; the method has the advantages of low cost, simplicity in operation and no secondary pollution and is suitable for being widely applied in eutrophicated freshwater and brackish water areas.

Description

technical field [0001] The invention relates to a biological technology product for algae control and water purification, in particular to the composition, type and action method of a biological community for algae control and water purification. The product can efficiently utilize the algae control characteristics and compound benefits of seawater fish and freshwater aquatic animals , let the cyanobacteria problem in the water be solved in situ in the water area, and serve for the efficient control of algae in the eutrophic freshwater body. Background technique [0002] With the rapid economic development and rapid population expansion, the total amount of pollutants received by natural water bodies has increased year by year, especially in the middle and lower reaches of the Yangtze River where the urbanization process is rapid, and almost all shallow lakes are eutrophic. Lakes distributed in the middle and lower reaches of the Yangtze River are often one of the main sourc...

Problems solved by technology

Practice has shown that it is impossible to plant aquatic plants in the whole water area with the common plant method, and plants can only absorb small molecular substances, and cannot reduce the amount of granular eutrophication substances. Planting aquatic plants in shallow water areas around the water area cannot solve the eutrophication of the entire water area The problem of material deposition and accumulation; stocking silver carp to filter-feed plankton in the water area is difficult to directly transform and utilize the organic matter deposited in the water area, and it cannot quickly and effectively solve the problems of cyanobacteria and eutrophication

In recent years, Academician Meng Wei, President of the Chinese Academy of Environmental Sciences, has predicted that the technical solution to the problem of cyanobacteria flooding is the "key biological chain", but at present, all R&D teams have not yet found the key elements of the "key biological chain", nor have they built a new and efficient one. Algae control biological chain, there is no key algae control water purification biological community
