河北省农村饮水安全工程供水模式研究

Study on Water Supply Modes of Rural Drinking Water Safety Projects in Hebei Province

河北省的农村饮水不安全类型主要是水质不达标，造成水质不达标的三大主因分别是：高氟、苦咸及水体污染。其次，缺水也是造成全省境内居民饮水困难的重要因素之一。针对以上的问题，河北省主要研发了两大类供水模式：集中供水模式和单村供水模式。目前，集中供水模式中使用率较高的模式有：机井＋集中式水厂＋村外管网＋村内管网＋用水户，地表水＋高位蓄水池＋村外管网＋村内管网＋用水户；单村供水模式中使用率较高的模式有：机井＋泵房＋村内管网十用水户，大口井＋泵房＋村内管网＋用水户，大口井＋泵房＋高位蓄水池＋村内管网＋用水户，截潜流＋泵房＋高位蓄水池＋村内管网＋用水户。

Rural unsafe drinking water type in Hebei province mainly is water quality out of standard with high-fluoride, bitter and salty, and water pollution as three major reasons. Another factor to cause people＇s not access to safe drinking water is water shortage. Hebei province have studied and developed two modes for water supply; centralized water supply mode and separated water supply mode aiming at solving those problems.
