摘要
处在快速发展中的新型中小城市其生活污水、工业废水及COD(Chemical Oxygen Demand)的排放量的变化和趋势有其共性,文章以池州市为个案,对池州市2000-2013年生活污水、工业废水及COD的排放量和进行了对比分析。结果显示:池州市2000-2013年城市污水排放总量呈上升趋势,生活污水的排放量上升趋势明显,城镇生活污水及COD的污染控制力度较小,工业废水及COD的控制与削减成效显著;新型中小城市水污染防治的重点急需从工业源为主的控制,快速转变为以城市生活源为主的控制。
In the rapid development of small-medium cities, changes and trends of domestic sewage and industrial waste water and their COD emissions have something in common. Domestic sewage, industrial wastewater and COD discharge of Chizhou city between 2000 and 2013 were analyzed. The tollowing results are shown:The total discharge of waste water between 2000 and 2013 demonstrated overall upward trend, of which the domestic sewage emissions rise significantly. And the control power of Chizhou City on pollution of urban sewage and COD was poor, the effectiveness of control and reduction of the industrial wastewater and COD result was significant.To small-medium city, the focus of prevention and control of urban water pollution should rapidly transformation from mainly control of industrial sources to control of urban life source.
