摘要
以污水处理厂二级出水加混凝、沉淀、过滤、消毒处理为依据,推导出中水处理系统的费用函数。由费用函数计算,当处理规模控制在150m3/d以上,则包括设备折旧的中水处理成本可降至1.50元/m3以下。中水设施的投入产出比为1∶4.83。
Livelihood drainage that is first biologically treated and then retreated with coagulation,settlement,filtration and disinfection processes can be used as tree and grass planting water or WC flashing water for the neighbouring residential areas.According to the calculation of the cost function,the cost can be reduced to less than 1.50 yuan RMB including equipment depreciation at a scale of 150 m3/d or more.Input output ratio of the treatment facilities is 1∶4.83.
