摘　　要：为减少西洋河淀粉废水中大量N、P、CODCr进入洋河水库,加剧水库的富营养化,进行了 生物滤池串联工艺处理西洋河淀粉废水的研究。结果表明:系统对淀粉废水中的氨氮、总氮、总磷、 可溶性总磷、正磷酸盐、CODCr均具有较好的去除效果,去除率可分别达到57．7％、58．7％、66．8％、 65．7％、67．4％、75．2％,且对进水浓度变化具有一定的适应性。The treatment of the starch preparation wastewater near the Yanghe Reservoir with submerged bio-filters system was investigated. When the inlet concentrations of NH3 -N, TN, TP, DTP,PO4^3- -P and CODCr are 0.9-31.2 mg/L, 2.5-56.6 mg/L, 1.2-8.3 mg/L, 0.7-4.9 mg/ L, 0.4- 4.0 mg/L and 98.2- 1 235.4 mg/L respectively, removal rates of 57.7 %, 58.7 %, 66.8 %, 65.7%, 67.4% and 75.2% were obtained for NH3 -N, TN, TP, DTP, PO4^3- -P and CODCr respectively. These meant that this system had good purification effects on the starch wastewater and it is resistant to concentration fluctuations of N, P and CODCr of the inlet raw wastewater.
