Effects of Shock Salinity Loading on Activated Sludge Treatment System
活性污泥处理系统耐含盐废水冲击负荷性能

The shock NaCl loading test was carried out in this experiment.Based on the experimental results obtained,following conclusions were reached:when the shocking influent with NaCl concentration less than 5g/L employed,no big influent on the biological treatment process occurred;but when the salt concentration was greater than 10g/L,oxygen uptake rate (OUR) of the sludge in the system reduced by 35% and total organic carbon(TOC) removal efficiency of the system dropped by 30%,approximately.
