摘要
通过建立临界距离数学模型,在满足经济规模的条件下,以集中式再生水厂所在位置为中心,以再生水最大允许输送距离(临界距离)为半径画圆,该区域内的再生水回用区宜采用集中式污水再生回用,区域外则采用分散式污水再生回用。应用该模型建立了坪山河流域综合治理规划临界距离数学模型,并分析了该流域内的11个规划水质净化站分散式布局模式的合理性,为坪山河流域规划或拟建污水厂或水质净化站工艺选择提供参考。
Based on the establishment of a mathematical model of the critical distance,under the condition of meeting the economic scale,a circle is drawn with the location of the centralized reclaimed water plant as the center and the maximum allowable transport distance of reclaimed water(critical distance)as the radius.In the circular area,centralized sewage regeneration and reuse method should be adopted in the reclaimed water reuse area,while decentralized sewage regeneration and reuse method should be adopted outside the circular area.The critical distance mathematical model for the comprehensive treatment plan of the Pingshan River Basin is established,and the rationality of the decentralized layout of 11 planned water purification stations in the basin is analyzed.It can be used as a reference for the planning and construction of sewage plants or water purification stations for the Pingshan River Basin.
