The Technology Of Circulating Cooling Water Reclamation

In this paper, D113weakly acidic ion exchange resin as the carrier, load zinc and aluminum ions as treatment material of circulating cooling water; explore its processing simulationthe effectiveness of the cooling water and into the dirt, corrosion the ion removal mechanisms and response factors through out the monitoring of the water sample conductivity, pH value, hardness, chloride ion content changes.Circulating cooling water treatment technology and hydrotalcite generation technology for the integrated.Hydrotalcite-like through the exchange process to improve the formation of ion-exchange process of treatment efficacy only to extend the breakthrough curves, giving the cation exchange resin to remove part of the anion function, in order to achieve the cooling water and the removal of ions synchronization resource, the water treatment process of product diversification; and by scanning electron microscopy and X-ray diffraction (XRD) analysis the product of the hydrotalcite-like crystal structure and surface elements. Research and zinc aluminum resin anion exchange resin to form a collaborative desalination capacity in the mixed bed.The results show that the influence of water flow rate and inlet temperature resin desalination capacity,6L/h better than the flow of2L/h desalination, the conductivity minimum can be reduced when the water flow for6L/h to400μs/cm, the pH value of6.21, hardness0.26mmol/L,33.78mg/L chlorine ion content. Order to improve the desalination capacity of the resin increased the temperature of the water, the results show that when the water temperature is40℃water treatment is stronger than the water temperature of15℃, when the water temperature is40℃, the lowest conductivity can be reduced to350μs/cm,pH value of5.03, a hardness of0.56mmol/L,42.54mg/L chlorine ion content. This process is the best operating conditions for the water flow6L/h, the water temperature of40℃.The transformation of zinc-aluminum resin not only have the water treatment capacity, and exchange column with well water (analog circulating cooling water) ion complexation reactions, by scanning electron microscopy and X-ray diffraction (XRD) analysis the product crystal structure and surface elements, which determine the product of a hydrotalcite-like.The article also explored the zinc-aluminum resin and strongly alkaline anion exchange resin mixed bed desalination capacity. The results showed that the lowest conductivity could be reduced to0.73μ s/cm, reaching the standards of deionized water.
