Abstract:

汉江作为长江的最大支流，是湖北省重要的饮用水源和工农业用水水源，同时也是南水北调中线工程的水源地，汉江水环境质量的优劣直接关系到社会经济的可持续发展。然而近年来汉江中下游水质趋于恶化，水体富营养化问题加剧，连年出现较为严重的水华现象，引起了社会的极大关注。本文通过对汉江中下游爆发水华前后部分水质参数监测结果进行对比分析，发现水华前后汉江水质参数变化特征是：pH值明显升高，溶解氧过饱和，叶绿素a大幅升高，硅藻中的小环藻属为优势种群，藻密度增加约3个数量级，氨氮含量有所下降。这将对饮用水源地的供水造成一定影响，需要增加针对水华的水处理措施。
The Hanjiang River as the largest tributary of the Yangtze River, is an important water source of drinking water and industrial and agricultural water in Hubei province, and is also the water source of south-to- north water transfer project; the Hanjiang River water environment quality is directly related to the sustainable development of social economy. However, in recent years, Hanjiang River water quality tends to deteriorate, compounding the problem of eutrophication; year after year more serious water bloom phenomenon has aroused great concern in the community. Based on the water quality parameters monitoring in Hanjiang River before and after the outbreak of algae bloom, the results show that pH value increased significantly, and the dissolved oxygen supersaturation and chlorophyll a increased. In the diatom Cyclotella genus was the dominant species, algae density increased by about 3 orders of magnitude, and ammonia nitrogen content declined. That will influence drinking water sources of water supply to some extent, thus needing to increase the water treatment measures for blooms.
