摘要
农村饮用水水源地一直是水源地保护中的薄弱环节,农村环境管理工作相对滞后,饮用水水源量多面广,情况复杂。通过对吉安市赣江中支吉水县10个典型农村饮用水水源地开展环境质量现状调查,结果表明:吉水县农村供水方式以分散式一家一井为主,地下水埋层浅。农村饮用水主要污染因子为来自生活污染源的阴离子合成洗涤剂、亚硝酸盐、氨氮、总大肠菌群或粪大肠菌群污染,其中细菌学指标污染物超标问题严重。比较不同供水方式水质,其中分散式-筒井受阴离子合成洗涤剂、亚硝酸盐、氨氮、总大肠菌群污染更为严重,污染物总类多,而分散式-手压井、集中式地下水、集中式-引泉污染物种类较少。并因此提出农村饮用水水源地环境保护对策。
Rural drinking water sources have long been a weak link in water source protection for the complexity and the backward situation of rural environment management. Environmental quality status survey of 10 rural drinking water sources in Jishui county typical rural areas was carried out. The results showed that the main rural water supply pattern of Jishui county was the pattern of scattered "one well for one home" from the shallow groundwater. The main pollution factors include anionic detergents, nitrite, ammonia nitrogen, total coliform bacteria or fecal coliforms, bacteriology index pollutants were seriously out of limits. The main limit-exceeding problem was bacteriology. Comparison the water quality of different supply pattern, there were higher anion synthetic detergent, nitrites, ammonia nitrogen, total coliform group in scattered tubular wells, but lower in scattered hand pumping wells, central groundwater wells and central spring sources. Based on the results, the corresponding protection countermeasures were put forward.
