摘　　要：通过批次和连续流试验分析了厌氧生物法对聚丙烯酸酯浆料废水的处理效果。批次试验结果表明,当水样稀释40倍(COD浓度为3 980 mg/L)时,对COD的去除率最高,为37.89%,甲烷产率最大,为118.98 m L/g COD。利用螺旋对称流厌氧反应器运行的连续流试验结果表明,在进水COD为4 000 mg/L左右、水力停留时间为3 d、中温(38℃)条件下,COD去除率维持在50%左右,出水p H值在8左右,B/C值由0.086升高至0.312。然而,出水氨氮浓度却由进水时的332.11 mg/L升高至2 189.26 mg/L,后续处理过程应考虑对高浓度氨氮废水的处理。The treatment performance of anaerobic biological process on polyacrylate desizing wastewater was studied in both of batch test and continuous flow test. The batch test results showed that, when the COD concentration was diluted by 40 times （ COD =3 980 mg/L）, the COD removal efficiency and the methane yield reached the maximum, which was 37.89% and 118.98 mL/gCOD, respectively. Based on the batch test results, a continuous flow test was carried out using the spiral symmetry stream anaerobic bioreactor （SSSAB）. The continuous test results suggested that when the influent COD concen- tration was 4 000 mg/L, the hydraulic retention time was 3 d, and the reactor temperature was 38 ℃, the COD removal efficiency of SSSAB reached 50%, the pH value was stable at around 8, and the B/C ratio increased from 0. 086 to 0. 312. This was beneficial to the subsequent aerobic biological treatment or other treatment process. However, the ammonia nitrogen concentration was increased from 332.11 mg/L to 2 189.26 mg/L after the anaerobic treatment, which should be addressed in subsequent treatments.
