摘要
由于活性炭再生困难,废弃后造成生态破坏,通过树脂的静态-动态吸附实验,筛选出D730丙烯酸系大孔强碱阴树脂,并优化其吸附-脱附条件。D730树脂代替颗粒活性炭去除水中有机物的小试结果显示,D730树脂较GAC再生容易,抗污染能力强,经济和社会效益高。D730树脂吸附-脱附的稳定性试验表明,各周期出水水质均很好且稳定,CODCr去除率达到80%以上,10个周期后,树脂理化性能仍保持很好,可望在电厂水处理中代替颗粒活性炭实现工业化应用。
Due to the high reclaim cost of granulated activated carbon, which will create environmental problems after inactivation, we screened from two adsorption resin by static and dynamic adsorption experiments and then optimized the adsorption-desorption conditions. In addition, a small-scale comparative test of removing organic matter from water by the resin and GAC was carried out. The results turned out that a macro porous strong base anion resin of acrylic acid-D730 with strong adsorption affinity and good anti-polluting capacity in contrast to GAC can be easily reclaimed by desorption, which also showed better economic and social effect. D730 resin confirmed its excellent adsorption capacity of organic compounds and stable performance in the stable test, more than 80% of CODcr removal efficiency has been obtained. After ten periodic test, physicochemical performance parameter of the resin still retained well-being, indicating an industry application prospect on removing organic substances from water as a substitute for GAC in power plant water treatment.
