Problems solved by technology

Common physical methods are water injection, bottom mud digging, etc., but this method requires a lot of manpower and material resources, and the effect is relatively short-term, and cannot fundamentally solve the problem of cyanobacteria blooms
The use of chemical agents such as copper sulfate can achieve a certain effect of algae removal, but frequent use of chemical agents is likely to damage the ecosystem population structure in the aquaculture water, and is toxic to the environment
Biological methods mainly include microbial control and food chain control, etc., but this method is slow to take effect, and it is not easy to establish a dynamic ecological balance system in the water body

Abstract

The invention discloses a plaster-base cyanobacteria treating agent. The plaster-base cyanobacteria treating agent of the invention is characterized by comprising the following raw materials in parts by weight: 10-15 parts of semi-hydrated gypsum, 10-15 parts of palygouskite, 5-10 parts of water hemp peel powder, 3-5 parts of lithium magnesium silicate, 3-5 parts of potato starch, 2-4 parts of aluminium chloride, 1-2 parts of malic acid, 3-5 parts of balloonflower powder, 1-2 parts of xanthan gum, 1-2 parts of magnesium chloride, 1-2 parts of aluminium sulfate and 10-15 parts of modifying adjuvant. The cyanobacteria treating agent can not only effectively adsorb and remove cyanobacteria in water, but also eliminate organic substances, nitrogen, phosphorus and heavy metals. The treating agent is characterized by abundant raw material source, low cost, good economical efficiency as well as excellent environment compatibility. The plaster-base cyanobacteria treating agent of the invention is free of environment pollution and is capable of effectively cleaning up water and river sediment so that the treating agent has strong practicality.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a gypsum-based cyanobacteria treatment agent and a preparation method thereof. Background technique [0002] Cyanobacteria bloom is a phenomenon in which cyanobacteria rapidly proliferate in large numbers in water bodies to form cyanobacteria colonies visible to the naked eye or cause changes in the color of water bodies. In recent years, environmental pollution has become increasingly serious, especially the aggravation of eutrophication in water bodies, resulting in frequent outbreaks of cyanobacteria blooms in water bodies, which brings great inconvenience to the lives of local residents and poses a serious threat to economic production and people's health. . [0003] At present, the prevention and control measures for cyanobacteria mainly include physical methods, chemical methods and biological methods. Common physical methods are water injection, bottom mud digging, etc., b...
