摘要
利用EGSB-A/O工艺处理高浓度的淀粉废水。EGSB反应器经过了接种污泥、驯化污泥、提高负荷及满负荷运行四个阶段后,完成启动过程,此时其COD负荷达到20kg/(m3.d),同时A/O段处理效果也随之稳定。经过4个多月的调试后,该系统对废水中COD、BOD5、SS和NH3-N去除率分别达99.1%、99.6%、82%和96%,出水水质达到《城市污水综合排放标准》(GB8978—1996)的一级排放标准,并可以回收蛋白与沼气,每年总收益达到84.59万元。
The expanded granular sludge bed （EGSB） reactor-A/O process has been used for treating highly concentrated starch wastewater. Anaerobic process is initiated by four stages, such as sludge inoculating, sludge domesticating, loading increase and full-scale running. The COD volume load of EGSB reaches up to 20 kg/（m^3·d）. The treatment efficiency of A/O process is steady as soon as the initiation of EGSB. After a four-month debugging, the removal rates of COD,BOD3,SS and NH3-N are 99.1% ,99.6% ,82% and 96%, respectively. After being treated by the combined process, the effluent quality is able to satisfy the demands of the first class standard of Integrated Municipal Sewage Discharge （GB 8978-1996）. At the same time, by anaerobic process, protein and biogas can be produced and recovered, and a total profit of RMB 845 900 can be obtained annually.
