摘　　要：处理高浓度变性淀粉生产废水由原来的好氧处理改为厌氧 (EGSB) 好氧处理 ,整套工艺只是在增加了厌氧反应器后 ,处理出水COD值可由改造前的 2 0 0 0mg/L变为改造后的10 0mg/L ,低于国家污水综合排放一级标准 ,并且运行费用比改造前相比明显降低。工程实践表明 。In this paper the aerobic biological process (activated sludge) was replaced by anaerobic biological process (EGSB) aerobic biological process (activated sludge) to treat the high COD metamorphotic amylum production wastewater, and only EGSB reactor was added and the final effluent can drop from former 2000 mg/L COD to current 100 mg/L COD, which is lower then The National Wastewater Discharge Standard Grade Ⅰand the charge of running was reduced So this process has much value of being popularized
