A kind of circulation efficient bactericidal composite
Technical field
The present invention relates to a kind of water treatment agent, particularly relate to a kind of circulation efficient bactericidal composite.
Background technology
In order to realize the sustainable optimized development of water resource, the process of water for industrial use and to recycle be necessary, and the pollution of industrial circulating water system mainly causes due to microorganism wherein.On the one hand, microorganism causes 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 can produce difference in oxygen concentration corrosion cell on the metal surface, iron is by dissolved corrosion, the gathering of foundry loam easily produces fouling, hinders heat transfer, serious meeting blocking pipe.Therefore control the microorganism in industrial circulating water and process can not only control water quality and degenerate, and can also energy consumption be reduced, extend the service life of instrument and equipment, be the key of circulating water cooling treatment, adopting bactericide to carry out control to the breeding of microorganism is that one is generally taked and effective way.
The oxidizing bactericide chlorine of bactericide, bromine series bactericidal agent that current domestic use is more, 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, more have isothiazolinone, glutaraldehyde, quaternary ammonium salt, wherein isothiazolinone is responsive to sulphide, invalid to sulfatereducting bacteria; Glutaraldehyde synthesis technique is more dangerous; Quaternary ammonium salt toxicity is little, cost is low and be widely used bacterium algae, but it is easy to foaming, and Long-Time Service bacterium easily develops 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 to intractable foundry loam rapid osmotic, sterilization, stripping, and is dispersed in water and discharges system with current.
For achieving the above object, the technical solution used in the present invention is:
A kind of circulation efficient bactericidal composite, it is characterized in that, comprise shitosan N-hydroxypropyl APEO dialkyl halide and fast T, the quality proportioning of each component is:
