A kind of circulation efficient bactericidal composite
Technical field
The present invention relates to a kind of water treatment agent, relate in particular to a kind of circulation efficient bactericidal composite.
Background technology
In order to realize the sustainable optimized development of water resource, the processing of water for industrial use and to recycle be necessary, and the pollution of industrial circulating water system is mainly because microorganism is wherein caused.On the one hand, microorganism is caused the direct pollution of water body; On the other hand, microorganism in industrial circulating water brings great harm to equipment, a large amount of foundry loams that it produces can cause corrosion in cycle water, foundry loam covers on metal surface can produce difference in oxygen concentration corrosion cell, the dissolved corrosion of iron, the gathering of foundry loam easily produces fouling, hinders and conducts heat, serious meeting blocking pipe.Therefore the microorganism in industrial circulating water is controlled and processed and can not only control water quality and degenerate, and can also reduce energy consumption, extend the service life of instrument and equipment, be the key of circulating cooling water treatment, adopting bactericide to control the breeding of microorganism is that one is generally taked and effective way.
The more bactericide of current domestic use has oxidizing bactericide chlorine, bromine series bactericidal agent, and this germicide series easily produces carcinogen chloroform, and the discharge of bromine class product can cause secondary pollution to water body.Another kind of bactericide is non-oxide class, and use more has isothiazolinone, glutaraldehyde, quaternary ammonium salt, and wherein isothiazolinone is to sulphide sensitivity, invalid to sulfatereducting bacteria; Glutaraldehyde synthesis technique is more dangerous; Quaternary ammonium salt toxicity is little, cost is low and bacterium algae is widely used, but it is easy to foaming, uses for a long time bacterium easily to develop immunity to drugs.
Summary of the invention
The object of this invention is to provide a kind of safety and environmental protection biological degradation, the circulation efficient bactericidal composite that nontoxic, pesticide resistance is little, said composition can be to intractable foundry loam rapid osmotic, sterilization, peel off, and is dispersed in water with current and discharges system.
For achieving the above object, the technical solution used in the present invention is:
A kind of circulation efficient bactericidal composite, is characterized in that, comprises shitosan N-hydroxypropyl APEO dialkyl group halide and fast T, and the quality proportioning of each component is:
