A modified brewer's grain inhibitor for blue-green algae and a preparing method thereof

Abstract

A modified brewer's grain inhibitor for blue-green algae is disclosed. The inhibitor is prepared through 30-40 parts by weight of brewer's grain, 10-20 parts by weight of wollastonite powder, 1-2 parts by weight of magnesium hydroxide, 5-10 parts by weight of bentonite, 3-5 parts by weight of acrylic acid, 0.05-0.1 part by weight of ammonium persulfate, 0.1-0.2 part by weight of sodium dodecyl sulfate, 0.5-1 part by weight of aluminium chloride, 1-2 parts by weight of acrylamide, 0.01-0.02 part by weight of N,N'-methylenebisacrylamide and 10-15 parts by weight of a composite auxiliary agent. The inhibitor is capable of rapidly and efficiently removing blue-green algae and toxins thereof, and effectively decomposing the settled blue-green algae and the toxins thereof, thus achieving objectives of purifying water and improving quality of bottom mud. The inhibitor is capable of inhibiting growth of the blue-green algae and preventing subsequent blue-green algae outbreak, thus achieving an objective of comprehensively and continuously controlling the blue-green algae. The inhibitor is low in cost, green, free of secondary pollution and suitable for application in aquatic water.

Description

technical field [0001] The invention relates to the field of cyanobacteria control, in particular to a modified brewer's grain cyanobacteria inhibitor and a preparation method thereof. Background technique [0002] When the environmental conditions are suitable and the nutrients are rich, blue-green algae will multiply rapidly and in large numbers, and form a layer of blue-green and foul-smelling floating foam on the water surface, which is called "water bloom". The distribution of cyanobacteria is very extensive in our country, and the outbreak of cyanobacteria bloom not only affects the ecosystem of water supply, tourism, landscape and aquaculture waters, but also seriously interferes with people's normal life. Therefore, the control of blue-green algae has become the focus of attention. [0003] Cyanobacteria usually accumulate on the surface of the water body or float in the water body, not only emitting odor, but also producing toxic and harmful substances such as cyan...

Problems solved by technology

However, a single cyanobacterial bloom treatment agent not only has its limitations, it cannot comprehensively and continuously control cyanobacterial blooms and their negative effects, and it will also bring follow-up problems such as secondary pollution
