摘　　要：以聚乙烯醇(PVA)凝胶颗粒作为微生物固定化载体,进行UASB反应器处理化学合成制药废水的试验研究。现场试验结果表明:经过17 d的培养得到PVA颗粒污泥初成体;接种PVA颗粒污泥初成体后,UASB反应器30 d完成污泥驯化,容积负荷由1.2 kg[CODCr]/(m3·d)提升至5 kg[CODCr]/(m^3·d);在进水水质波动较大情的况下(CODCr的质量浓度为2 540~5 210 mg/L),稳定运行期以容积负荷7 kg[CODCr]/(m3·d)运行,去除率稳定在70%左右;运行结束后,得到沉降性能优良的PVA颗粒污泥,沉降速度在120~140 m/h之间。A test of chemical synthesis pharmaceutical wastewater treatment by UASB reactor was carried out with PVA-gel beads as the microbial immobilization carrier. The field test results showed that, over 17 days cultivation, the PVA granular sludge has been initially formed and then was inoculated in an UASB reactor. After 30 days continuous operation, sludge acclimatization was completed, the volume loading was promoted from 1.2 to 5 kg[CODcr]/（m3·d）. Under the condition that the influent water quality fluctuated strongly（the mass concentration of CODcr was 2 540 - 5 210 mg/L）, during the stable operation period with volume loading of 7 kg[CODcr]/ （m3 ·d）, the removal rate of CODcr was maintained at about 70%. At the end of the operation, PVA granular sludge with good sedimentation performance was gotten, and the sedimentation velocity was 120 - 140 m/h.
