城市河流有机物污染监测与评价

The Monitoring and Evaluation of Organic Pollution of the River in Northeast

通过对东北地区四平市城区河流水体中有机污染物监测,以地表水Ⅳ类水质限值为标准分析得出:阴离子表面活性剂不超标,CODCr、CODMn、BOD5和挥发酚超标严重,多个采样点超标率达100%,且有发展趋势;城市活动加重了河流有机物污染程度,北河污染程度大于南河.另外,人工暗河河水转入河流后加重了有机物污染,对下游水体构成了严重威胁,应引起高度重视.

The concentration of anionic surface active agent didn＇ t exceed the standard, but the concentration of CODcr, CODMn, BOD5 and volatilizing phenol had far exceeded water quality Ⅳ standard of surface water（GB3838-2002） ;exceeding standard rate reached 100% in many sampling points, and developing trend; the degree of organic pollution was increased by urban activities, the degree of pollution in north river is more serious than in the south river. In addition, organic pollution was inflected seriously by manual underground fiver water, need to be governed in North-east area, it is stared in the face.
