摘要
随着经济的进步,水污染问题日益凸显,水资源短缺越来越严重,这不仅制约了城市的经济、社会、环境的可持续发展,更是对人体健康造成了威胁,为了解郑州市近年来污染物排放状况及对其原因进行分析,本文对近几年污染物排放量进行调查,结果表明污水排放总量逐渐上升,这与人口增加、工农业需水量增加有关;主要限排物质COD、氨氮的排放量总体呈下降趋势,但个别年份出现突增现象,这可能与政府的环保政策改变及个别工业偷排有关,对此本研究提出相适应的建议。
With the progress of social economy,water pollution problems have become increasingly prominent and water resource pinched has become more serious. It will not only prevent the economic,social and environmental sustainable development in Zhengzhou city,but also to be a threat to people＇s health.
