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 liqui

example 1

[0018] Weigh 100g of Scutellaria chinensis and 80g of Scutellaria baicalensis respectively, put them into a mincer and mix them with 1L of absolute ethanol. After mixing, they will ultrasonically extract for 1 hour at a power of 200W. The original volume is 20% to obtain a concentrated solution; add 4g of sodium alginate to the above concentrated solution, stir until the sodium alginate is completely dissolved to obtain a sodium alginate solution, then weigh 3g of chitosan and add it to 60mL of 0.5% hydrochloric acid to dissolve , to obtain chitosan solution, and mix it with sodium alginate solution, stir to obtain viscous liquid, and set aside; take 80g brown sugar and add it to 500mL sterile water, stir until brown sugar dissolves, add 5gEM bacterial powder to brown sugar water, Stir and mix at 35°C for 30 minutes, then incubate for 20 hours, and obtain bacterial solution after cultivation; weigh 120 g of glucose, 5 g of peptone, 2 g of corn flour, 10 g of beef extract, 1 g o...

[0021] Weigh 125g of Scutellaria chinensis and 100g of Scutellaria baicalensis respectively, put them into a grinder and mix them with 1.5L of absolute ethanol. After mixing, ultrasonically extract for 1.5h at a power of 225W. Evaporate to 25% of the original volume to obtain a concentrated solution; add 5g sodium alginate to the above concentrated solution, stir until the sodium alginate is completely dissolved to obtain a sodium alginate solution, then weigh 3-5g chitosan and add 70mL mass fraction 0.5 % hydrochloric acid to obtain chitosan solution, and mix it with sodium alginate solution to obtain viscous solution after stirring evenly, and set aside; weigh 85g brown sugar and add it to 550mL sterile water, stir until brown sugar dissolves, add 6gEM to brown sugar water Bacteria powder, stirred and mixed at 37°C for 40 minutes, incubated for 25 hours, and obtained bacterial liquid after cultivation; weighed 135g glucose, 8g peptone, 2.5g corn flour, 13g beef extract, 1.5g ...

example 3

[0024] Weigh 150g of Scutellaria chinensis and 120g of Scutellaria baicalensis respectively, put them into a mincer and mix them with 2L of absolute ethanol. After mixing, they ultrasonically extract for 2 hours at a power of 250W. The original volume is 30% to obtain a concentrated solution; add 6g of sodium alginate to the above concentrated solution, stir until the sodium alginate is completely dissolved to obtain a sodium alginate solution, then weigh 5g of chitosan and add it to 80mL of 0.5% hydrochloric acid to dissolve , to obtain a chitosan solution, and mix it with a sodium alginate solution, stir evenly to obtain a viscous liquid, and set aside; take 90g brown sugar and add it to 600mL sterile water, stir until the brown sugar dissolves, add 7gEM bacterial powder to the brown sugar water, and Stir and mix at 40°C for 50 minutes, then incubate for 30 hours, and obtain bacterial liquid after cultivation; weigh 150g of glucose, 10g of peptone, 3g of corn flour, 15g of be...

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...
