摘要:
本文采用混凝–超滤工艺处理微污染原水，考察工艺除污性能，并与传统工艺进行比较。试验表明：在最佳工艺组合参数条件下，超滤膜对浊度的去除率为95.61%，对CODMn的去除率为40.42%，对UV254的去除率为37.12%；除在低温低浊期超滤膜出水UV254效果较差外，其他水质期超滤膜各出水水质指标效果均优于传统工艺。This paper investigated the decontamination performances on the treatment of micropolluted raw water by applying coagulation-ultrafiltration technology and compared this technology with the traditional process. The results showed that under the best combination of process parameters, the removal rates of turbidity, CODMn and UV254 by ul- trafiltration were 95.61%, 40.42%, and 37.12% respectively. Water quality index of ultrafiltration was better than that of the traditional process, except that effluent of membrane UV254 effect was poor under low temperature and low turbid-ity.
