Description
Technical field the present invention relates to a kind of water treatment BCDMH and C5H6Br2N2O2 compound disinfectant and preparation method thereof, and product is applicable to industrial cooling circulating water, waste water treatment, middle water recycling and the disinfection algae removals such as agricultural irrigation water and swimming-pool water.
Background technology
Stable development along with China's economy, the contradiction of supply and demand for the water resource is day by day remarkable, improve the availability of water resource, greatly develop the Industrial Water Saving technology, improve agricultural irrigation water efficient, develop the environment-friendly highly efficient water treatment becomes the present water treatment industry of China with the disinfection algicide the task of top priority.At present water treatment has two kinds of oxidized form and Non-oxidizeds with the disinfection algicide, in oxidized form disinfection algicide, commonly used have chlorine dioxide, Peracetic acid, hydrogen peroxide, clorox (calcium), sodium dichloro cyanurate, sym-closene, two chlordantoins, BCDMH, a C5H6Br2N2O2.Except Peracetic acid and hydrogen peroxide, be chloride and bromine-containing disinfectant in the above-mentioned product.They can be effectively to the water sterilization that carries out disinfection, but in water body Cl
+Ion can corroding metal and contaminated environment, and the product that has therein an environmental-protecting performance only has BCDMH and C5H6Br2N2O2.
BCDMH, full name are 1-bromo-3-chloro-5, and the 5-dimethyl hydantion also claims 1-bromo-3-chloro-5,5-dimethyl-2,4-imidazolidimedione.BCDMH mainly is used as cooling water system, swimming-pool water, agricultural irrigation and house warming system water treatment microbicide commonly used, biocide, extremely slime mould agent, algicide, bactericide and fungicide and uses as novel brominated chloride a oxidizing disinfect.Be used for abroad swimming pool more than 90%, cooling water system unify disinfection and the algae removal of hot spring.BCDMH constantly discharges Br in water when using as the Water Disinfection agent
+Ion and Cl
+Ion forms hypobromous acid and hypochlorous acid with bactericidal action, and the reaction that discharges bromine in water is very fast, and the reaction that discharges chlorine is slower, simultaneously the bromine anion of hypochlorous acid after bactericidal action is oxidized to hypobromous acid again, produces the hypobromous acid of nascent state, further improves the disinfection bath effect of going out.
C5H6Br2N2O2, full name are 1,3-, two bromo-5, and the 5-dimethyl hydantion also claims 1,3-, two bromo-5,5-dimethyl-2,4-mew oxazolidinedione.Use as medication chemistry bromating agent and disinfectant at present.Be mainly used in aquaculture, livestock-raising, daily life disinfection, the disinfection of industrial cooling circulating water, waste water treatment and swimming-pool water and algae removal etc. as new and effective disinfectant.C5H6Br2N2O2 constantly discharges Br in water when using as the Water Disinfection agent
+Ion, the speed that discharges bromine is very fast, and formation has the hypobromous acid of bactericidal action in a large number rapidly, is safety, environmental protection, high-effective disinfecting Biocidal algae-killing agent.
BCDMH discharges Cl in water
+Ion is slower, and the time on the disinfection peak that forms in water relatively lags behind, so use C5H6Br2N2O2 to have than other halogenated hydantoins such as BCDMH and the higher disinfecting/sterilizing efficiency of two chlordantoins under the relative Quick disinfection sterilizing of needs bath condition.C5H6Br2N2O2 is high as the independent use cost of disinfection algicide, is unfavorable for promoting.For this reason, use BCDMH, C5H6Br2N2O2,5,5-dimethyl hydantion, sodium carbonate and anhydrous citric acid are made compound disinfecting tablet, can have the advantage of using DBDMH disinfecting agent, reduced production cost, improve the cost performance of disinfection algicide, use 5 of rear remnants, the 5-dimethyl hydantion is carbon, hydrogen, oxygen compound, biological degradability is good, through light, oxygen and microbial degradation ammonification and carbonic acid gas, noresidue does not pollute water body under field conditions (factors).Therefore it is imperative with BCDMH and C5H6Br2N2O2 compound disinfecting tablet to develop a kind of environment-friendly type water processing.
Summary of the invention the object of the present invention is to provide a kind of environment-friendly type water to process with BCDMH and C5H6Br2N2O2 compound disinfectant, and it can be used for industrial cooling circulating water, waste water treatment, water recycling and agricultural irrigation water and swimming-pool water disinfection and the bath etc. of going out.
Another object of the present invention provides the preparation method that BCDMH and C5H6Br2N2O2 compound disinfectant are used in water treatment.
Purpose of the present invention is achieved through the following technical solutions.
A kind of water treatment is with BCDMH and C5H6Br2N2O2 compound disinfectant, is to be suppressed behind the mixing granulation by mass percentage by following component to form:
Water treatment BCDMH and C5H6Br2N2O2 compound disinfectant preparation method:
At first with above-mentioned BCDMH powder, C5H6Br2N2O2 powder, 5,5-dimethyl hydantion, sodium carbonate and anhydrous citric acid are dried respectively, moisture requirement≤0.3%; Then by each constituent mass percentage weighing, add the mixer mixing and stirring, mixing time is controlled at 30-50 minute; Material after mixing is added comminutor cause 8-35 purpose particle; Again the particle that causes is added tablet press machine and namely be pressed into BCDMH and C5H6Br2N2O2 compound disinfecting tablet.
Described water treatment is with BCDMH and C5H6Br2N2O2 compound disinfectant, is to be suppressed behind the mixing granulation by mass percentage by following component to form:
Described water treatment BCDMH and C5H6Br2N2O2 compound disinfectant, the content that each component is specifically selected materials:
