Fig. 1 is the schematic diagram of the embodiment one of the Water Treatment in Circulating Cooling System of ozone cooperative film process of the present invention.
Fig. 2 is the schematic diagram of the embodiment two of the Water Treatment in Circulating Cooling System of ozone cooperative film process of the present invention.
Embodiment
The present invention is further described with specific embodiment below in conjunction with the accompanying drawings.
Ozone is a kind of strong oxidizer, can kill the biological bacteria in water rapidly under finite concentration；What ozone decomposed was produced
Oxygen atom can react with iron ion, iron pipe surface is formed the gamma-iron oxide passivating film of densification, corrosion inhibition is played to system；
Organic matter in ozone energy oxidation Decomposition dirt matrix, makes dirt fluff and come off, reaches anti-scale descaling purpose.Ozone is used as water process
Agent, with simple to operate, sterilizing ability is strong, improves cycles of concentration, water-saving and emission-reducing, the advantages of secondary pollution is not present again, to following
The inhibition of ring water, scale inhibition, kill livestock in terms of have good effect.
Reverse osmosis membrane system is mainly used for removing salinity, colloid and impurity in circulating sewage etc., and clearance is reachable
98%, production water is as supplement water, and fully recovering is into circulation, and concentrated water is through being concentrated by evaporation, and crystalline solid is separated from water synthesis
Using or disposal, distilled water fully recovering fully achieves zero-emission.
Comparative example：
