一、深层地下水开采状况及需水量预测 深层地下水开采状况。阜阳市城区面积50平方公里,城市人口24万,工业总产值25亿元,是一个全部用深层地下水为供水水源的城市。随着城市建设和经济的发展,深层地下水的开采量逐年增加。1981年深井93眼,年开采量2440万立方米,合每天6.7万立方米;1990年增加到218眼,年开采量4015万立方米,合每天11万立方米;1994年达到246眼,年用水量4740万立方米,合每天13万立方米。 城市需水量预测。根据阜阳市
First, the status of deep groundwater exploitation and water demand prediction Deep groundwater exploitation. Fuyang City, an urban area of 50 square kilometers, urban population 240,000, industrial output value of 2.5 billion yuan, is a full use of deep groundwater for water supply city. With the urban construction and economic development, the exploitation of deep groundwater has been increasing year by year. In 1981, there were 93 deep wells and the annual extraction volume was 24.4 million cubic meters, 67,000 cubic meters per day. In 1990, it was increased to 218. The annual production was 40.15 million cubic meters, or 110,000 cubic meters per day. In 1994, it reached 246 eyes. 47.4 million cubic meters of water, combined with 130,000 cubic meters a day. Urban water demand forecast. According to Fuyang City
