Optimization and research of membrane filter press procedure on dehydration of sludge
摘要
Abstract
In order to study filterability of membrane filter press in each work stage, the filter processes were simulated to find the regulation between the filter volume and the work time by software Fluent. And the algorithm was fitted by the least square method. According to the simulation results, a conception named virtual filter volume that can describe the regulation between the filter volume and work time in the stage of inflating membrane was put forward by mathematical method. Then the efficiency formula of filter press was derived. The results show that pressure filter time is the key factor to the efficiency formula of filter press, and the work efficiency of a certain sludge treatment plant is increased by 37.7% using this mathematical method. The optimum work cycle time of filter press is obtained, and its work efficiency is improved greatly.关键词
