Research and Application of Distributed Effluent-treatment Systems

摘要：

　　Distributed effluent-treatment systems is selected as the effluent-treatment system for Plant M.Using water-pinch technology for wastewater minimization,a distributed effluent-treatment system segregates the different streams for separate treatments and only combines them if appropriate.For this multiple-contaminant and multiple-treatment process,minimum treatment flow rate of each contaminant is determined first (the true minimum treatment flow rate is the maximum flow rate among the minimum treatment flow rates for all contaminants); next,subnetwork is designed for the treatment of each contaminant; then,merge all the subnetworks and make all possible simplifications to obtain the final optimum treatment network.Distributed effluent-treatment systems present more advantages compared with centralized effluent-treatment systems.In a distributed effluent-treatment system,the streams are segregated and treated separately,reducing both capital and operating costs.The minimum treatment flow rate of Plant M is 114.25t/h,and the overall wastewater flow rate is 148t/h.The wastewater flow rate is reduced by 23%.
