Description
Technical field：
The present invention relates to algicide, particularly a kind of Compositional type that can quickly remove microcystic aeruginosa and water silk floss is except algae
Agent.
Background technology：
Body eutrophication is the common problem that countries in the world face caused by water pollution, and the water body in China is rich
Nutrient laden is fast-developing in the past 30 years, the waters such as lake, river, coastal waters eutrophication getting worse.Occur therefrom
Wawter bloom, red tide phenomenon also more and more frequently, caused by endanger it is also increasing, it has also become the research hotspot of field of water pollution control
One of with problem, wherein harmful algae control is important topic therein.Triggering the algae of wawter bloom has very much, according to algae not
Together, cyanobacterial bloom, green alga wawter bloom and bloom of diatoms etc. are roughly divided into, wherein, cyanobacterial bloom is the most universal in eutrophication water,
Microcystic aeruginosa is then most common sociales.In addition, some filamentous algaes, such as water is continuous, bristle algae is in some waters some seasons
Save amount reproduction, they or be wrapped on submerged plant body or swim in water meter or be covered in the bed mud surface of shallow water bottom,
Water landscape, submerged plant growth etc. are caused to seriously affect, and general algicide is directed to planktonic algae, and to water
The filiform algae killing effect such as silk floss is little, one of the problem of being troubling in current water ecology repair process.
Based on this, China never stops in the research except algae aspect, except the method for algae is also constantly being improved.Current removes
Algae method is broadly divided into Physical, bioanalysis and chemical method.Wherein except algae efficiency highest, effect is best, shortest being of timeliness
Method.The algae of outburst growth is quickly killed using chemical algicide, is to carry out environmental improvement and contaminant water now
The important way that body recovers.Though the chemical algicide species nowadays on domestic market is various, using effect is irregular.
The content of the invention：
The object of the present invention is to provide a kind of Compositional type algicide simple for process, easy to process, using effect is good and its
Preparation method.
The technical scheme is that a kind of compounding algicide, it is characterised in that：The present invention is by chlorine dioxide and dichloro-benzenes
(base) dimethyl urea (DCMU) compounds；The chlorine dioxide removes algae bactericidal agent for commercially available chlorine dioxide, is needed before use
Water is added to be configured to solution.It is described it is algaecide combined in, the mass ratio of chlorine dioxide and dichloro-benzenes (base) dimethyl urea is 1:1.
A kind of processing technology for compounding algicide, its preparation method are：
Chlorine dioxide powder is dissolved in 4 DEG C of distilled water, according to the mass fraction of chlorine dioxide in powder, 1mg/ is finally made
The ClO 2 solution of ml, and refrigerate in refrigerator；
Dichloro-benzenes (base) dimethyl urea is dissolved in acetone, is configured to dichloro-benzenes (base) dimethyl urea-acetone soln of 1mg/ml；
It is shaken up after ClO 2 solution and dichloro-benzenes (base) dimethyl urea of same volume-acetone soln mixing, is sealed in glass
It is placed in 4 DEG C of refrigerators and refrigerates in glass bottle.
According to the different concentration of object different set when this product uses.
Killing microcystic aeruginosa and during chlorella, the concentration for compounding algicide is preferably 0.5mg/L or following；Concentration
For 0.5mg/L~2mg/L when 24 is small interior algaecidal rate reach more than 50%, 96 it is small when more than algaecidal rate reach more than 90%,
And it is not recurred in 15 days；Algaecidal rate reaches more than 95% in 15min when concentration is 5mg/L~10mg/L, is not recurred in 24 days.
Algicide is compounded when killing water silk floss, the concentration for compounding algicide is preferably 2~10mg/L.In 5d, concentration is
The compounding algicide algaecidal rate of 2mg/L reaches 77%, 10mg/L when reaching 75%, 5mg/L and reaches 85%.In 10d, 2~10mg/
The compounding algicide algaecidal rate of L reaches more than 95%.
The technique of the present invention is compounded using chlorine dioxide and dichloro-benzenes (base) dimethyl urea, and what is obtained is algaecide combined,
It can greatly improve to kill algae in the short time and kill algae efficiency, and long period algae can be maintained not recur；And algal control after compounding
Effect during any effect with obvious effects better than in the two under same concentrations, be also significantly better than common a variety of algicide (see
Table 1, table 2, table 3), the concentration of the common algicide such as dichloro-benzenes (base) dimethyl urea can be greatly reduced, reduced to aquatic ecological
The injury of system.The present invention is the highly efficiency compositional algicide that a kind of effect is good, rapid-action.
