Description

Blue algae treatment agent prepared by a kind of coconut husk and preparation method thereof

Technical field

The present invention relates to water treatment field, be specifically related to blue algae treatment agent prepared by a kind of coconut husk and preparation method thereof.

Background technology

Blue-green alga bloom is a kind of phenomenon that the blue-green algae rapid, high volume propagation in water body forms macroscopic blue-green algae colony or causes water body color to change, can at the floating algae mat gathering formation one deck green of water surface time serious, even algae slurry.In recent years, being on the rise of environmental pollution, especially the increasing the weight of of body eutrophication, cause blue-green alga bloom frequently to break out in water body, bring great inconvenience to the life of local resident, very serious to the threat of economic production and people ' s health.

At present, physical method, chemical process and biological process etc. are mainly contained to the prevention and control measure of blue-green algae.Physical method is common changes note Xin Shui, dig bed mud etc., but this method needs at substantial manpower and materials, and effectiveness comparison short-term, can not fundamentally solve blue-green alga bloom problem.Use the chemicals such as copper sulfate to play certain for algae effect, but the frequent chemicals etc. that uses easily destroys ecosystem population structure in aquaculture water, and to environment, there is toxicity.Biological method mainly contains microbial control and food chain control etc., and this method still takes effect comparatively slow, not easily in water body, sets up dynamic ecological balanced system.
