Optimal Design Of Sedimentation Tanks

In this paper, the problems of optimal design of sedimentation tanks are studied by adopting theories and methods of system engineering to seek the scheme of the least sedimentation tanks building cost. It is significant to reduce sedimentation tank cost and water and waste water plant cost.The optimal designs of horizontal sedimentation tanks and plated upflow sedimentation tanks are made when sedimentation data is provided or not. By BP neural network perfoming nonlinear mapping and combining regression orthogonal,the sedimentation tank cost functions are set up, the objectives are provided. The sedimentation tank designs are demanded to meet the efficiency and the hydrolic condition ,and the parameters are comfined in the range according to the criterion , so the integrate optimal design models are set up.The Hopfield network optimal computation theory combining simulating annealing is applied in this paper to make caculation. Nonlinear dynamical systems of the nonlinear programming model of the horizontal sedimentation tanks and plated upflow sedimentation tanks are separately constituted and solved by software simulation method which utilized the neural network dynamical evolution property.It is economical and feasible in such method to gain optimal design of sedimentation tanks.
