摘要
研究了改性沸石、TiO_2、改性沸石/TiO_2联用协同预处理黄家湖微污染水的效果并进行对比分析。结果表明:改性沸石/TiO_2联用预处理黄家湖水源水效果最好,并且在处理浊度为2.06 NTU,COD质量浓度为74.59 mg/L,氨氮质量浓度为0.316 mg/L的黄家湖微污染水时,改性沸石/TiO_2投量比为20 1,处理时间为1 h预处理效果最佳。浊度、COD、氨氮、UV254去除率分别达到93.4%,81.7%,87.3%,79.1%。
The effects of modified zeolite,TiO2,modified zeolite/TiO2on the treatment of micro-polluted water in Huangjia Lake were studied and compared.The results showed that the pretreatment with modified zeolite/TiO2was effective.And when dealing with Huangjia Lake micro-polluted water for1h,the pretreatment effect was best in conditions of turbidity2.06NTU,COD74.59mg/L,ammonia nitrogen0.316mg/L and the modified zeolite/TiO2dosage ratio201.Under the above conditions,the removal rate of turbidity,COD,ammonia nitrogen and UV254reached93.4%,81.7%,87.3%and79.1%respectively.
