【摘要】 从产水系统的全局出发,综合考虑了系统中混凝、沉淀、过滤等各处理单元的运行状态及相互关系.通过分析水厂产水过程中反冲洗用水、沉淀池排泥、混凝投药率对制水成本的影响,提出产水系统优化运行的费用函数,研究了优化模型的解法,并编制了相应的求解程序.使用实际数据进行考核计算,结果表明该优化计算方案可使制水成本显著降低.更多还原

【Abstract】 Basing on a viewpoint of all sided water producing system,a comprehensive analysis of the operation status and the relationship between each working unit in water producing system,including coagulation,sedimentation and filtration etc.was made.By investigating the influence of backwashing consumption,the amount of sludge ejected from sedimentation tank and coagulant ratio upon the cost,the cost effective function of the system was presented.Afterwards,the solution was found out and the corresponding computer program was developed.When applied with real world data,it proved that this method significantly reduced the water producing cost.更多还原
