摘要
为了解决农村饮水问题,郑州市进行了农村饮水不安全问题的调查与研究。结果表明,农村饮水不安全人口为140万人,占农村总人口的33.64%。水质不安全问题主要是高氟水、苦咸水和污染水,分别占农村总人口的6%、9%和15%,高氟水的形成原因主要是水对含氟矿物的淋溶、山前断陷带氟的大量聚集和工业污染;苦咸地下水的形成是古地理环境、地貌、气候条件、地质构造和积盐作用共同导致的结果;污染水主要由于城市雨污水、工业废水污染河流,进而污染河流周围的地下水。部分县市还存在水源保证率、生活用水量及用水方便程度方面不达标问题。针对上述问题,提出了相应的技术、建设管理、投资、运行管理对策。
For solving potable water problems in villages, unsafe problems in potable water were investigated and studied in Zhengzhou city. It is indicated that population with unsafe potable water is 1 400 thousand, 33.64% of the total village population. Unsafe water quality problems are high fluorine waterbitter and salt water, polluted water, and they respectively take 6 %, 9%and 15 %of total village population. The reason of high fluorine water are solution of fluorine mineral,accumulation of fluorine in fault zone of mountain front and industry pollution. Bitter and salt water is due to ancient geographical environment,geomorphic feature,climate condition,geological structure and salt accumulation. Groundwater is contaminated by rivers which is polluted by urban sewage and industry waste water. Water source,water quantity and water use convenience are not up to the standards in some counties. Countermeasure of technique,construction management,investment and operation management are put forward.
