Research On Recovery Technology Of Resin By Photovoltaic Micro-electrolysis

Ion exchange resins are pure and ultra-pure water preparation process indispensable material, Suitable for regeneration and recovery device and method of ion exchange water treatment technology is bound to worry about lifting, This article has been contaminated select strong base anion exchange resin regeneration and recovery targets. In the open electrolytic cell self-designed experimental study, DC power-driven and were attempting to direct electrical regeneration process designed to target and regeneration experimental device.Micro-porous filter device using titanium anode, cathode stainless steel housing, First, in order to optimize the DC power-driven recovery resin regeneration conditions, Explore the optimal operating parameters for the regenerative voltage 30V, regeneration time 4h, water flow rate 2.4L/h. It can be reproduced in a single experiment 500ml contaminated strongly basic anion exchange resin, Power consumption of about 0.23kwh, water consumption about 9.6L. Take 40ml and 20ml electrical regeneration chemical resin mixed resin regeneration Yang.60ml water mixed resin can handle 5.6L, Where water is tap water conductivity 380?s ? cm-1, and by mixing the resin treated water conductivity is less than or equal to 100?s?cm-1, the minimum conductivity of the water is 3.7 ?s?cm-1.The article also reduce energy consumption from the perspective of electrical regeneration equipment has been improved, made a number of specific improvements, including the use of changing water-tap water as raw water, use solar power instead of batteries DC power supply, improved experimental device (Add 100mlAl (OH) 3 colloids), In other experiments under the same conditions, while the above improvements,60ml mixed resin can handle water desalination experiments 2.5L, the minimum conductivity of the water is 14.5?s?cm-1; else being equal, the regeneration time of 8h under recovery anion resin, 60ml mixed resin desalination experiments can handle water 3.9L. minimum conductivity of the water is 5.5?s ? cm-1, obtained from the experimental results can be seen in the above improvements is entirely feasible, from reducing energy consumption and improve the efficiency and environmental point of the experiment, these improvements have a great practical significance.
