Preparation method of ecological and environment-friendly composite biological algaecide

Abstract

The invention discloses a preparation method of an ecological and environment-friendly composite biological algaecide and belongs to the field of algaecide preparation. Active liquor is obtained from tender catchweed bedstraw herb and radix scutellariae through microwave extraction, concentrated liquor is obtained after concentration, sodium alginate is added into the concentrated liquor, a chitosan solution is added after dissolution, viscous liquor is obtained after uniform stirring, EM bacterial powder is firstly activated with brown sugar water, a fermentation culture medium is inoculated with activated bacterial liquor, fermentation liquor is obtained through fermentation culture, dried wormcast and the fermentation liquor are mixed, the mixture is still standing and then mixed with the standby viscous liquor, the materials are mixed, then the mixture is filtered, and filter residues, namely the biological algaecide are obtained. The prepared biological algaecide is free of toxins, good in dispersity, good in algae removal effect and long in algae inhibition acting time.

Description

technical field [0001] The invention discloses a preparation method of an ecological and environment-friendly compound biological algaecide, which belongs to the field of algaecide preparation. Background technique [0002] The eutrophication of water bodies caused by water pollution is a common problem faced by countries all over the world. The eutrophication of water bodies in my country has developed rapidly in the past 30 years, and the phenomenon of eutrophication in lakes, rivers, and coastal waters has become increasingly serious. The resulting algal blooms and red tides are becoming more and more frequent, causing more and more harm, and have become one of the research hotspots and difficult problems in the field of water pollution control, among which the control of harmful algae is an important topic. There are many algae that cause water blooms. According to different algae species, they can be roughly divided into cyanobacteria blooms, green algae blooms, and dia...

Problems solved by technology

[0004] The main technical problem to be solved by the present invention is that the traditional chemical algae removal cannot fundamentally improve the water quality. On the contrary, with the increase of the dosage and the continuous replacement of the types of chemicals, the secondary pollution to the environment is also increasing, thus The problem of causing a serious vicious circle in the water quality environment provides a preparation method of an ecological and environmental protection compound biological algaecide. The present invention first extracts the active liquid from pig scorpion and Scutellaria baicalensis with microwaves, and then concentrates to obtain a concentrated liquid. Add sodium alginate to the liquid, add chitosan solution after dissolving, and get viscous liquid after stirring evenly. Activate the EM bacteria powder with brown sugar water first, inoculate the activated bacteria liquid into the fermentation medium, and ferment and cultivate to obtain the fermentation liquid , mix the dried vermicompost with the fermented liquid, put it aside and mix it with the standby viscous liquid, filter it after mixing, and get the filter residue, which is the biological algaecide. The biological algaecide prepared by the present invention is non-toxic , Good dispersibility, good algae removal effect, long time algae inhibition, no side effects on water quality
