Description
Technical field
The present invention relates to a kind of Biocidal algae-killing agent, in particular to it is cold to belong to industrial cycle for a kind of environment-friendly type Biocidal algae-killing agent
But water-treatment technology field.
Background technique
In general recirculating cooling water system, since water body is recycled for a long time, the equipment such as pipeline and cooling tower are easy
Hyperplasia microorganism and biological clay can be such that reverse osmosis membrane water filtration efficiency reduces, corrosion-mitigation scale-inhibition if handling or dealing with improperly not in time
Agent partial failure, equipment corrosion failure, when serious biological clay can completely plugged pipeline, influence the normal of recirculating cooling water system
Work.How to effectively control bacterium algae growth and breedings in recirculating cooling water system to have become the important content in water treatment technology.
Currently, chemical bactericide is generallyd use to the processing of bacterium algae in cooling water system both at home and abroad, wherein being divided into oxidation again
Property fungicide and non oxidizing bactericide.Though oxidizing bactericide is cheap, usage amount is few, vulnerable to water quality and corrosion-mitigation scale-inhibition
Agent influences, while equipment being easily caused to corrode；Part non-oxidative bactericide not only has bactericidal effect, but also to bactericidal activity
Component has synergistic effect, has the very strong removing effect of falling off to foundry loam.Therefore, processing water system is used currently on the market
It is non-oxidative bactericide mostly.
Chinese invention patent application 200910233377.0 is related to a kind of composite sterilization algicide of slow-release, chief active
Ingredient is bromochloroin and isocyanuric acids oxidant, and it is excellent that this medicament has that easy to use, applicable pH range is wide, stability is good etc.
Point, but isocyanuric acids oxidant therein is influenced vulnerable to Organic substance in water, is used for a long time simultaneously, easily is caused to corrode to equipment.
Chinese invention patent application 201410274544.7 is related to Biocidal algae-killing agent and the application of a kind of suitable industrial water system, mainly
Ingredient is dazomet and quaternary alkylphosphonium salt, but is used for a long time, and microorganism causes drug resistance, but quaternary alkylphosphonium salt conduct used in it to dazomet
Flocculation treatment agent uses, and P elements are just to provide the nutrients of microorganism.
Many Biocidal algae-killing agents are mainly with isothiazolinone and dodecyl dimethyl benzyl ammonium chloride currently on the market
It compounds, although this kind of medicament has a significant effect, pharmacy variety is single, if being used for a long time, in circulation
Microorganism easily cause drug resistance, the advantage in later period is also not obvious.
