摘　　要：对比好氧污泥-固定化光合细菌和好氧污泥-未固定化光合细菌联合处理皂素废水的处理效果。实验结果表明：固定化光合细菌耐受的COD浓度范围明显增大,耐氯性达到20 000 mg/L,适宜的p H范围变宽为5.0-9.0。对于COD浓度为5 000 mg·L^-1-30 000 mg·L^-1的皂素废水,投加5%V固定光合细菌∶V活性污泥=1 mL·mL^-1∶1 mL·mL^-1的接种量,好氧污泥-固定化光合细菌联合处理其CODcr去除率稳定在97%-99%,光合细菌的流失量大大减少,且固液分离效果好。Compare the aerobic sludge- anaerobic- aerobic sludge- immobilized photosynthetic bacteria immobilized photosynthetic bacteria effect of combined treatment of saponin wastewater treatment. The experimental results show that： COD concentration range of the resistance of immobilized photosynthetic bacteria increased obviously,chlorine resistance up to 20 000 mg / L,the suitable pH range wider 5. 0 - 9. 0. The concentration of COD was 5 000 - 30 000 mg·L^- 1,diosgenin wastewater,adding5% V fixed photosynthetic bacteria inoculum amount of activated sludge in V = 1 ∶1 m · Lm L^- 1,aerobic sludge immobilized photosynthetic bacteria combined treatment the CODcrremoval rate stable at 97 - 99%,loss of photosynthetic bacteria is greatly reduced,and good solid- liquid separation effect.
