摘要
采用颗粒污泥和普通絮体污泥SBR反应器对维生素C生产废水进行可生化性对比试验研究，结果表明，在进水CODcr为400—1800mg／L，运行周期为8h，其中曝气时间为5．5h，换水比为80％的条件下，颗粒污泥反应器CODer去除率为75-90％，污泥浓度介于6．11～8．32g／L，污泥指数为20～40mL／g.
The treatment of Vitamin C wastewater by SBR process has been studied. With the concentration of 400 - 1800mg/L of wastewater in the inlet, 8h react period, 5. 5h aeration time and 80% wastewater change rate, the removal rate of CODcr is between 75% -90%, MLSS is between 6. 11% and 8.32% and SVI is between 20 -40mg/g.
