摘要
对长江安庆段进行水质监测。观察指标:色、臭、肉眼可见物、pH值、总硬度、硫酸盐、氯化物、溶解性固体、铁、铜、锌、氰化物、六价铬、砷、汞、镉、铅、总α放射性、总β放射性、总大肠菌群、溶解氧、生化需氧量、氨氮、硫化物、苯胺、石油类和挥发酚类。除石油、挥发酚类、铁、汞和总大肠菌群有超标外,其余均符合我国《生活饮用水卫生标准》或《地面水环境质量标准》第二级或《地面水中有害物质的最高容许浓度》的规定。使用综合水质指数WQI对水质进行评价,A、B、C、D、E 5个断面的WQI分别为0.67、1.164、0.68、1.102、0.565。远离城市的E断面水质较好;B断面水质较差,其原因是受到石油等的污染。
The water of the part of Anqing of Yangzi River was monitored. The investigation indexes inclode color, odour, visible substances, pH, hardness, sulphate, chloride, total dissolved solids, Fe, Cu, Zn, CN^-, Cr^(5+), As, Hg, Cd, Pb, total α radiation, toat1 β radiation, total coliform group, DO, BOD_5, NH_3-N, sulphide, aniline, petroleum and volatile phenols. The results show that except petroleum, volatile phenols, Fe, Hg and coliform group which exceeded the MAC, the other indexes were within the limits of the values of national sanitary standard for drinking water or the second class of national environmental quality standard for surface water or MAC of hazardous materials for surface water. Water quality index (WQI) was used to evaluate the water. WQI of the sectinos A, B, C, D and E were 0.67, 1.164,0.68, 1.102, and 0.565 respectively. The section Elsquality is the beast of all of the five sections, and section B's is the worst due to the petroleum pollution.
