The slow-release type composite sterilization algicide comprises the following components in percentage by weight: 20 to 50 percent of bromine hydantoins, 20 to 40 percent of isocyanuric acid oxidants, 10 to 20 percent of stabilizer, 10 to 20 percent of bonding agent and 10 to 20 percent of water. The preparation method comprises the following steps of: dissolving the isocyanuric acid oxidants, the stabilizer and the bonding agent into water in proportion; mixing the mixture, adding the bromine hydantoins to the mixture in proportion, and mixing the mixture to obtain the composite sterilization algicide. The composite sterilization algicide has obvious sterilization and algae removal effects on bacteria, algae and the like in a water system.
Description
Technical field
The invention belongs to water treatment agent production and applied technical field, particularly relate to highly efficient composite bactericidal algaecide of a kind of spacetabs type and preparation method thereof, the bacterium in water system, algae etc. are had significant sterilization algae removal effect.
Background technology
In water for industrial use and domestic use of water, body eutrophication has become one of principal element of using of restriction water conservancy.The excessive multiplication of bacterium and algae has a strong impact on the function of water body, pollutes on the one hand waterline, stops up the filter tank, causes the water supply accident; On the other hand, can cause water body smelly, affect view.Industrial, can cause biological clay to stop up heat transmission equipment, corroding metal, affect the safety in production of factory.Therefore, the control of bacterium and algae is become the main water quality deterioration of water quality.
Be these problems that bacterium and algae in solution water bring, be necessary its harm to equipment in water being processed avoid it to enter industrial system with machinery, method chemistry or being controlled industrial process water.
Chemical agent is one of the method for processing the most effective, the most convenient of bacterium and algae in water body.Traditional Biocidal algae-killing agent has chlorine, drift ice, ozone and ClO
2Deng, but under high pH condition and in water body when having more organic pollutant, the effect of chlorine class biocide reduces greatly, ozone and ClO
2Although processing effective, be limited to cost factor and safety factor, be difficult to promote.
Bromine class biocide is a development in recent years class oxidisability biocide comparatively rapidly, as active bromine, BCDMH, organic bromine etc., the speed of killing livestock is faster than chlorine, still can bring into play its efficient sterilization algae removal performance when high pH value and Organic Pollutants In Water exist, and the incomparable superiority of chlorine is arranged.
The main component of the highly efficient composite bactericidal algaecide of spacetabs type is glycolylurea class biocide, usually has following 3 kinds:
1-bromo-3-chloro-5,5-dimethyl hydantion 3-bromo-1-chloro-5,5-dimethyl hydantion 1,3-two bromo-5,5-dimethyl hydantion
Its effect of killing livestock is to generate hypochlorous acid and hypobromous acid is completed by hydrolysis, belongs to a kind of oxidative bactericide.Have that consumption is low, applicable pH range is wide,, the advantages such as excitant little, good stability little to metal equipment corrosion.Bromine class glycolylurea biocide is highly effective bactericide with broad spectrum, and its molecular energy penetrates rapidly the cell membrane of microorganism, and acts on certain albumen group, the normal oxidation of cell-reduction is stopped, thereby cause cell death.Decomposition rate is very fast in alkaline water quality, can be degraded to rapidly innocuous substance after completing bactericidal action, and is favourable to environmental protection, has certain foundry loam and peels off effect.But higher the becoming of its price limited its widely used one of the main reasons.
Summary of the invention
The composite sterilization algicide that the purpose of this invention is to provide a kind of spacetabs type, another object of the present invention are to provide the preparation method of above-mentioned composite sterilization algicide, solve bacterium and the not good problem of algae control with medicament in industry water.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of highly efficient composite bactericidal algaecide of spacetabs type is characterized in that the percentage by weight that its component and each component account for the Biocidal algae-killing agent total amount is respectively: bromine class glycolylurea 20%-50%, isocyanuric acids oxidant 20%-40%, stabilizing agent 10-20%, adhesive 10%-20% and water 10%-20%.
Described bromine class sea is preferably 1-bromo-3-chloro-5,5-dimethyl hydantion, 3-bromo-1-chloro-5,5-dimethyl hydantion or 1,3-, two bromo-5,5-dimethyl hydantion.
