摘要
调查了杭州市主城区浅层地下水水质现状。结果表明,杭州市主城区浅层地下水污染较重,"三氮"超标现象普遍,而主要污染项目为NH3-N、NO2--N、IMn和总大肠菌群及细菌总数。指出,农业面源污染和生活污水,是造成杭州市主城区浅层地下水氮污染的主要原因。提出分析了地下水水质污染的成因。指出应加强地下水保护以及地下水资源的质量管理。进行科学、合理地开发利用,实现地下水水资源的可持续利用,支持杭州市国民经济的可持续发展。
The situation of sallow ground water quality in urban area of Hangzhou was investigated.The results indicated agricultural polluting sources and sewage caused heavy pollution of the water.The detecting values of ammonia,nitrate and nitrite had been out of limits of national environmental standard.The pollutant indicators were NH3-N,NO2^--N,IMn,coliforms and total number of bacteria.Priority was given to strengthen the protection of ground water and quality management of ground water resources,to scientifically and reasonably exploit ground water resources,and to realize the sustainable utilization of ground water resources for sustainable development of the national economy.
