[0029] The preparation method of photosynthetically active additive is:

[0030] S1. Take Rhodopseudomonas palustris and inoculate it into the activation medium at an inoculum size of 7-10%, incubate at a light intensity of 3000lx and 25-28°C for 4-7 days, centrifuge, take the precipitate a, take the precipitate a and press Mass ratio 1~4:10~20 Add Tris-HCl buffer solution with pH 8.0 and concentration of 10mmol / L, shake for 20~30min, centrifuge, take the precipitate b, take the precipitate b according to the mass ratio 1~3:5~8 Add the dissolving solution and mix, keep warm at -30~-20°C for 30~45min, thaw, repeat the warming and thawing process for 2~4 times, and sonicate for 10~15min to obtain the ultrasonic solution;

[0031] S2. Take the ultrasonic liquid and add polyethylene glycol octyl phenyl ether and sodium chloride according to the mass ratio of 100~200:1~3:0.1~0.3, stir and mix at 25~30°C for 1~3h, and then in 1~4 Stand still at ℃ for 12~15h, centrifuge, take the su...

Abstract

The invention discloses a compound algicide and a preparation method thereof and belongs to the technical field of biological environmental protection. In the method, rhodopseudomonas palustris is activated and cultured under light conditions, dissolved pigment protein active substances are extracted, and the pigment protein active substances are converted to glucose by the aid of CO2 or H2S and water in algae photosynthesis for catalytic oxidation. Long-term effect of algae removal can be played by the aid of tetra-butyl titanate, acetic acid and other substances since the addition of the pigment protein active substances can continuous to grow and propagate to promote photocatalytic reaction; rectorite is taken as a raw material added with sodium silicate and ferric sulfate to generate active substances with fluocculation and turbidity removal functions in situ, certain oxidation capacity and electric neutralization effects are achieved, eutrophic substances and algal toxin are removed, good removal effect on algae cells is achieved, and algae removal efficiency is prompted; problems about short maintain time and poor algae removal effect of an existing algicide are solved.

Description

technical field [0001] The invention belongs to the technical field of biological environmental protection, and in particular relates to a compound algicide and a preparation method thereof. Background technique [0002] The algicide has good bactericidal and algae killing ability in different pH ranges, can effectively dig out algae reproduction and slime growth, and has dispersion and osmosis effects, can penetrate and remove slime and peel off attached algae , In addition, it also has the ability to remove oil. It is suitable for the killing of algae and microorganisms in various water systems, such as the treatment of circulating cooling water systems such as fish ponds, ponds, river courses, large central air conditioners, engineering heat exchange, and manufacturing processes. [0003] As we all know, the cause of algae bloom is due to excessive nitrogen and phosphorus pollutants discharged into the lake body, resulting in eutrophication of the lake water. Under suita...
