Abstract
The invention discloses a composite disinfecting algaecide for circulating water. The composite disinfecting algaecide for the circulating water is made of mixture of isothiazolinone, diacetylmonoxime, acetoxime and water. Weight percentages of the isothiazolinone, the diacetylmonoxime, the acetoxime and the water in the composite disinfecting algaecide for the circulating water are respectively 5-15 percents, 15-25 percents, 15-30 percents and 40-60 percents. Novel materials are compounded so that the composite disinfecting algaecide for the circulating water increases special effects of deoxygenization, anti oxidation and corrosion inhibition on the basis of having performance of sterilization and algae removal of a traditional single disinfecting algaecide. Meanwhile, the composite disinfecting algaecide for the circulating water is low in cost, and does not cause secondary pollution for a cooling circulation system.
Description
Technical field
The present invention relates to a kind of Biocidal algae-killing agent for cooling recirculation system bacterium algae pollution, specifically a kind of highly efficient composite bactericidal algaecide of cooling recirculation system.
Background technology
Under the situation that development that present economy is advanced by leaps and bounds and environmental pollution are on the rise, lack of water phenomenon and water quality deterioration problem are increasingly outstanding, so the task of water treatment seems and becomes more and more important.Along with the continuous propelling of water technology, the application of cooling circulating water is universal, because the equipment of cool cycles mostly is material steel or copper making, wherein for to prevent that cooling system from suffering the infringement of bacterium algae to become the important problem of present water treatment.Bacterium algae in the water all can pollute obstruction to the present conventional cooling-cycle apparatus that uses, the control impact of bacterium algae in water becomes a difficult problem, yet the method for control bacterium algae mainly contains: ultraviolet sterilization, oxidation disinfection, utilize the method such as toxicology killing bacteria; Ultraviolet sterilization wherein generally adopts ultraviolet ray, and bacterium algae moment was killed in effect lower moment of ultraviolet light.The shortcoming of this method is the equipment that needs to drop into ultraviolet radiation preventing, and sometimes also needs to add catalyzer, because the decision of cell self property can not be killed by ultraviolet ray sometimes, causes more serious pollution and can produce variation in addition; Oxidation disinfection has good effect to the bacterium algae, causes the expendable damage of cooling tube but be easy to make oxidant to enter cooling system if any operational issue; But the toxicology sterilization is killed livestock effect very obviously the very difficult degraded of general biocide to the bacterium algae, and its toxicity need to processed and can discharge cycle water environmental hazard is large more by force; The primary raw material of Biocidal algae-killing agent is aldehyde material, quaternary ammonium salt, hydrogen peroxide, hypochlorite etc. at present, in the higher water of temperature, generally adopts the amount of bactericide larger, and the composition of Biocidal algae-killing agent itself causes secondary pollution to cooling recirculation system.
Summary of the invention
For above defective, the invention provides that a kind of consumption is few, cost is lower, effective and can not cause the efficient sterilizing algicide of secondary pollution to cooling recirculation system to sterilization algae removal, thereby can be in effective sterilization algae removal and reach the purpose of good deoxygenation and corrosion mitigating effect, and toxicity be lower.
The composite sterilization algicide of cycle water of the present invention is mixed by isothiazolinone, diacetylmonoxime, acetoxime and water.
In the described composite sterilization algicide, the percentage by weight of isothiazolinone, diacetylmonoxime, acetoxime and water is preferably respectively 5%-15%, 15%-25%, 15%-30% and 40%-60%, more preferably be respectively 8%-12%, 16%-21%, 17%-26% and 50%, most preferably be respectively 10%, 20%, 20% and 50%.
High efficiency composition Biocidal algae-killing agent of the present invention is by making isothiazolinone, diacetylmonoxime, acetoxime and water mixing and stirring.
The beneficial effect of efficient sterilizing algicide of the present invention is: make Biocidal algae-killing agent of the present invention on the basis with the sterilization of traditional single Biocidal algae-killing agent, algae removal performance by the composite of novel material, increased the effect of the anti-oxidation and inhibition of special deoxygenation; Cost is lower, and can not cause secondary pollution to cooling recirculation system.
