衡水市地表水水质状况分析

Analysis of Surface Water Quality Status of Hengshui City

衡水市地表水水资源贫乏且污染严重，直接影响着衡水市的工农业发展以及居民的生活健康。通过对衡水市地表水进行水化学分类、离子径流量及径流模数、矿化度、总硬度等一系列的分析研究显示，衡水市地表水水化学类型以氯化物钠型水为主，其次为重碳酸钠型水，离子径流量及离子径流模数的年内分配，主要取决于径流量的年内分配，与暴雨发生的时间相对应，矿化度变幅在412-5360mg／L之间，总硬度介于82．4-757mg／L。

The shortage of water resources and the pollution of surface water directly influence the development of industry and agriculture, as well as the healthy life of dtizen＆ A series of analysis-chernical classification for water,ion runoff, runoff modulus salinity, total hardness and so on found that the type of surface water is mainly sodium chloride, followed by sodium bicarbonate The distribution of ion runoff and runoff modulus yearly depends on the distribution of runoff in a year, corresponding to the time of heavy rain. The mineralization amplitude is 412- 5360 mg/L, total hardness ranges from 82.4-757 mg/L. The shortage and pollution of water has constrained the economic development of Hengshui. Coordinated development between the city＇s environment and economy, the pollution emissions must be controlled. The forecast and preventive level for sudden water pollution incidents should be improved. The study for quality prediction should be carried oht to control water pollution
