引言 在以去除悬浮物为目的的水处理工程中,“混凝沉淀——过滤”是常采用的工艺流程。它由投药、混合、反应、沉淀及过滤等单元组成。在各单元的设计能力、容量及参数间存在着相互制约和相互影响的关系。如果把诸单元组合成的整体看作为一个系统,在流程和单元的设计中,不只是求其某一单元的合理化,而是对单元组合成的整体进行系统的优化分析,就可达到使系统最优化这一目标。 本文试以投药混凝、水平沉淀池、重力式无阀滤池为主要设施的系统作为示例,选择适宜的决策变量,识别“混凝沉淀——过滤”过程的数学模型,并对它进行参数估值。同时,
Introduction In the water treatment project for the purpose of removing suspended solids, “coagulation sedimentation - filtration” is a commonly used process. It consists of units for administration, mixing, reaction, precipitation and filtration. There are mutual restrictions and mutual influences among the design capabilities, capacity and parameters of each unit. If the whole unit is considered as a system, in the design of processes and units, not only the rationalization of a certain unit, but the systematic optimization analysis of the whole unit composition can be achieved. Optimize this goal. In this paper, we use the system of chemical coagulation, horizontal settling tank and gravity-type valveless filter as the main facilities as an example, select the appropriate decision variables, identify the mathematical model of the “coagulation and sedimentation-filtration” process, and carry out parameters for it.
