Embodiment 1

[0025] A processing technology of compound algicide, its preparation method is:

[0026] Dissolve chlorine dioxide powder in distilled water at 4°C, and finally prepare a 1 mg / ml chlorine dioxide solution according to the mass fraction of chlorine dioxide in the powder, and store it in a refrigerator.

[0027] Dissolve dichlorobenzene (yl) dimethyl urea powder in acetone to prepare a 1 mg / ml dichlorobenzene (yl) dimethyl urea-acetone solution.

[0028] The chlorine dioxide solution of the same volume and the dichlorobenzene (yl) dimethyl urea-acetone solution are mixed, shaken evenly, sealed in a glass bottle and placed in a refrigerator at 4° C. to refrigerate.

[0029] In practical application, if algae killing is aimed at Chlorella or Microcystis aeruginosa in 10L of water body, 5ml of compound algicide should be put into the water body so that the concentration of algicide in the target water body is 0.5mg / L. The ideal algicidal effect can be achieved 5 days after adding....

Embodiment 2

[0031] A processing technology of compound algicide, its preparation method is:

[0032] Dissolve chlorine dioxide powder in distilled water at 4°C, and finally prepare a 1 mg / ml chlorine dioxide solution according to the mass fraction of chlorine dioxide in the powder, and store it in a refrigerator.

[0033] Dissolve dichlorobenzene (yl) dimethyl urea powder in acetone to prepare a 1 mg / ml dichlorobenzene (yl) dimethyl urea-acetone solution.

[0034] The chlorine dioxide solution of the same volume and the dichlorobenzene (yl) dimethyl urea-acetone solution are mixed, shaken evenly, sealed in a glass bottle and placed in a refrigerator at 4° C. to refrigerate.

[0035] In practical application, if algae killing is aimed at Chlorella or Microcystis aeruginosa in 10L of water body, 10ml of compound algicide should be put into the water body so that the concentration of algicide in the target water body is 1mg / L. The ideal algicidal effect can be achieved in the last 5 days. ...

Embodiment 3

[0037] A processing technology of compound algicide, its preparation method is:

[0038] Dissolve chlorine dioxide powder in distilled water at 4°C, and finally prepare a 1 mg / ml chlorine dioxide solution according to the mass fraction of chlorine dioxide in the powder, and store it in a refrigerator.

[0039] Dissolve dichlorobenzene (yl) dimethyl urea powder in acetone to prepare a 1 mg / ml dichlorobenzene (yl) dimethyl urea-acetone solution.

[0040] The chlorine dioxide solution of the same volume and the dichlorobenzene (yl) dimethyl urea-acetone solution are mixed, shaken evenly, sealed in a glass bottle and placed in a refrigerator at 4° C. to refrigerate.

[0041] In practical application, if chlorella, Microcystis aeruginosa or Spirogyra are used to kill algae in a 10L water body, 20ml of compound algicide should be put into the water body so that the algicide concentration in the target water body is 2mg / L After 5 days of dosing, all the chlorella and Microcystis aer...

Abstract

The invention discloses a compounded algicide and a preparation method thereof. The compounded algicide is compounded from chlorine dioxide and DCMU (dichlorobenzene dimethyl urea), wherein chlorine dioxide is an algae-removing chlorine dioxide sterilizing agent sold in the market, water is added before chlorine dioxide is used, and a solution is prepared. The preparation method comprises steps as follows: chlorine dioxide powder is dissolved in distilled water at the temperature of 4 DEG C, and a 1 mg / ml chlorine dioxide solution is finally prepared according to the mass percentage of chlorine dioxide in the powder and refrigerated in a refrigerator; DCMU is dissolved in acetone, and a 1 mg / ml DCMU-acetone solution is prepared; the chlorine dioxide solution and the DCMU-acetone solution which have the same volume are mixed, uniformly shaken and sealed in a glass bottle to be refrigerated in the refrigerator at the temperature of 4 DEG C. The efficient compounded algicide has a good effect and takes effect quickly.

Description

Technical field: [0001] The invention relates to an algaecide, in particular to a compound type algaecide that can quickly remove Microcystis aeruginosa and Spirogyra. 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 diatom blooms. Among them, c...
