| 摘 要： | 为了保证城市的可持续发展,科学准确地预测废水排放量是十分必要的。因为它是城市排水系统规划和管理的基础,也关系到城市的污水系统及污水处理厂的合理规划。文章基于天津市1990—2009年工业废水排放量的历史数据,采用投影寻踪回归法,对天津市2010—2015年工业废水排放量进行了预测研究。结果表明,在＂十二五＂期间,天津市的经济继续保持快速发展,但由于加强了＂减排＂工作的力度和对废水的治理,＂十二五＂期间的工业废水排放量整体趋向于平稳,相比＂十一五＂期间还有小幅降低。

| Abstract: | In order to ensure the sustainable development of cities,scientific and accurate forecast of urban waste water is critical in drainage system planning and management,and is also related to the rational planning of sewage system and sewage treatment plants.Based on the historical data of industrial wastewater in Tianjin from 1990 to 2009,using projection pursuit regression algorithm,the industrial wastewater in Tianjin during 2010—2015 is predicted.Results show that during "the twelfth five year" period,the economic growth of Tianjin will maintain a rapid speed,but the industrial wastewater in Tianjin as a whole tends to remain stable and slightly reduced compared to the previous "five-year" period due to the reduction and treatment of the waster water. |
