Description
Technical field
The present invention relates generally to a kind of sterilization and alga-killing remover and the application in circulating water treatment thereof.
Background technology
The long-term water temperature of recirculated cooling water is in 10～40 ℃ of scopes, and is and sunny, and nutriment is abundant, is the favorable environment of growth of microorganism, breeding.A large amount of breedings of microorganism bring hidden danger to the operation of circulation.
Microorganism in the control cycle water can be taked diverse ways according to their growth conditions.As prevent solar radiation, improve water temperature, adopt bypath filter and supplementing water carried out preliminary treatment etc., be to add biocide but adopt maximum a few days ago.
Can be divided into oxidized form and non-oxide type biocide two big classes by the mechanism of killing livestock, as Cl
2, NaClO, O
3, ClO
2With chloramines etc. be the oxidized form biocide, quaternary ammonium salt, chlorophenol etc. is non-oxide type biocide.Oxidized form biocide poor stability, also bigger to the corrosivity of equipment.Non-oxide type biocide is of a great variety, and the mechanism of killing livestock also has nothing in common with each other.
Single biocide uses for a long time, and biology can develop immunity to drugs, and the effect of killing livestock can reduce gradually.
Summary of the invention
The objective of the invention is to avoid the deficiencies in the prior art that a kind of sterilization and alga-killing remover for circulating water is provided.Little to solve to equipment corrosion, germicidal efficiency is high, consumption is few, mud, the microorganism that sticks to equipment surface had the very strong effect of peeling off.The present invention adopts kill livestock composite the forming of non-oxide type biocide of principle of multiple difference, has solved biological pesticide resistance problem.
For achieving the above object, the technical scheme that the present invention takes is: a kind of sterilization and alga-killing remover for circulating water, its main feature is isothiazolinone 0.5～3%wt by weight percentage, copper sulphate 0.1～0.5%wt, chlorine or bromine dodecylbenzyl ammonium 10～35%wt, glutaraldehyde 0～10%wt, sulfuric acid 0.015～0.025%wt, surplus is a water.
The preparation method: the above-mentioned raw materials of commercially available variable concentrations is converted into pure product, takes by weighing the back according to the above ratio and add in the reactor, copper sulphate needs water dissolving back to add, and slowly stirs, and after waiting to stir, leaves standstill in the plastic containers of packing into to the lather collapse.
Isothiazolinone all has the good ability of killing livestock to algae, fungi and bacterium under low concentration, in the pH value scope of broad, chlorination dodecyl dimethyl benzyl or bromination dodecyl dimethyl hexadecyldimethyl benzyl ammonium are quaternary cationic surfactant, its sterilization instant effect, and can be penetrated into the inside of bacterium dirt layer, the bacterium colony of absorption on the equipment wall killed, make it under current scour, to split away off from the apparatus wall, this characteristic be other Biocidal algae-killing agents can't be obtained.Glutaraldehyde is 7.5～8.5 o'clock in the pH value, acts on the byest force, and the pH value in recirculated cooling water when operation is generally in this scope, but the brood body of kill bacteria and gemma, fungi, virus, the sterilization instant effect.
It is the kill livestock non-oxide type biocides of principle of several differences that isothiazolinone, chlorine (bromine) are changed dodecylbenzyl ammonium, copper sulphate, glutaraldehyde, selects this several composite performance synergistic effects for use, improves germicidal efficiency, and can make biological pesticide resistance senior general low.Find to add stability and the germicidal efficiency that a small amount of sulfuric acid helps improving system in the compound system.This compound system finds that in utilization its bactericide consumption is less than the prescription that only uses isothiazolinone, and thoroughly the required time ratio of sterilization only shortens 2～3 days with the prescription of isothiazolinone, and peels off the effect excellence.
The invention has the beneficial effects as follows: the present invention is non-oxidative bactericide, be used for circulation, promptly have the sterilization algae removal function effect of peeling off algae, dirt from equipment surface is arranged again, adopt the impact type mode to add to have instant effect, sterilization is thorough, characteristics such as biomolecule resistant difference.
