| 摘 要： | 本试验通过对比两种预氧化剂对夏季滦河水的藻类、CODMn、UV254、TOC等指标的去除效果，分析水中分子量的分布情况，研究了高锰酸钾和氯预氧化对有机物的去除效果。结果表明，KMnO4预氧化在去除有机污染物方面的效果要好于预氯化的处理效果；高锰酸钾预氧化的UV254去除率为23．4％，而TOC去除率为7．1％，说明一部分UV吸收性有机物在预氧化过程中转变为UV非吸收陛有机物，低高锰酸钾投量条件下水中有机物不能得到完全去除。 |

| Abstract: | Through comparison of removal effect of.both pre-oxidants on algae,CODNn,UV254TOC etc. indexes in Luanhe River water in summer and analysis of MW distribution in water by HHLC,the effect of potassium permanganate and chlorine pre-oxidation on organics removal was studied. The results showed that the effect of KMnO4 pre-oxidation on the removal of organic pollutants was better than that of chlorine pre-oxidation; UV254 removal rate by KMnO4 pre-oxidation was 23.4%,while TOC removal rate was 7.9%, indicating that partial UV254 adsorbing organics were converted into non-UV254 adsorbing organics in the course ofpre-oxidation; organics could not be removed fully at low dosage of KMnO4. |
| Keywords: | potassium permanganate chlorine pre-oxidation surface water |
