摘要
Abstract
On the basis of solid flux theory, the design parameters of secondary sedimentation tank was studied in this article. It is shown that sediment process includes sedimentary deposit stage, transitory stage and compression stage during the measurement. Sludge sedimentation rate is quite fit with Vesilind equation (νd=9.74e-13964c,R2=0.839 4). Critical solid flux is achieved when MLSS is 5.50 g/L. By stepwise of Matlab, it is shown apparent concentration efficiency is not affected by the flow distribution ratio, but notably affected by the influent sludge concentration and influent flow rate.关键词
