| 摘 要： | 采用1 m^3/h中试装置高锰酸钾预氧化-微絮凝-超滤组合工艺处理引黄水库水,并考察了对水中污染物的强化去除效能及对膜通量的影响。试验结果表明,高锰酸钾预氧化可有效提高超滤系统对水中污染物的去除,且高锰酸钾投加量在0.5 mg/L时组合工艺运行效果达到最佳。此外,高锰酸钾可以改善膜渗透性能,延缓了跨膜压差增长速率。

| Abstract: | The 1 m^3/h combined process with pre-oxidation of potassium permanganate,microflocculation and ultra-filtration was used to treat reservior water from the Yellow River. The enhanced pollutant removal efficiency and the effect of membrane flux were investigated. The results showed that the pre-oxidation of potassium permanganate could effectively enhance the pollutant removal with the ultra-filtration system. When the dosage of potassium permanganate was 0. 5 mg /L,the operational effect of the combined process could achieve the optimal condition. In addition,potassium permanganate could improve membrane permeability and alleviate increasing rate of trans-membrane pressure. |
