摘　　要：通过动态分配化学一、二期制水系统制水量,合理安排化学制水系统中各阴、阳、混合离子交换器的运行方式和制水周期,使各阴、阳、混合离子交换器尽可能按比例集中再生(即“协同再生”),同时最大化利用废水池的有效容积,使呈酸性、碱性的再生废水在排入水池后达到“自中和”效果,最终仅需对混合后的废水进行pH值微调即可满足排放要求,从而降低了用于中和废水的酸、碱药耗和除盐水综合制水成本。By dynamically allocating the water production capacity of the chemical first and second-stage water systems,and reasonably arranging the operation modes and water production cycles of the cation,anion,and mixed ion exchange units in the chemical water production system,this study ensures that the cation,anion,and mixed ion exchangers regenerate in a proportional,centralized manner(i.e.,"cooperative regeneration").Mean-while,it maximizes the effective volume of the wastewater tank,allowing the acidic and alkaline regeneration wastewater to reach a"self-neutralization"effect after being discharged into the tank.As a result,only slight pH adjustments are needed for the mixed wastewater to meet discharge requirements,thereby reducing the consump-tion of acid and alkali chemicals for neutralizing wastewater and lowering the overall desalinated water production costs.
