摘　　要：采用“水解酸化＋SBR＋微滤”工艺处理制浆造纸中段废水。试验结果表明，在原废水CODα为1100-1500mg，L、pH为6．8-7．2，水解工艺水温为25-30℃、HRT为6h、碳氮比为60：1，SBR工艺反应时间为8h、温度为34-38℃的条件下，组合工艺对废水COD。氨氮、总磷、SS和TOC的平均去除率分别为91．8％、93．8％、94．7％、100％和91．4％，出水水质达到《制浆造纸工业水污染物排放标准》（GB3544-2008）的要求。微滤膜置于生化反应后，降低了膜污染．同时对污染物质有一定的拦截效果。The “hydrolytic acidification-SBR-microfiltration” combined treating process has been used for treating mid-stage wastewater in pulp and paper industry. The experimental results show that by the combined process,the average removing rates of CODc,, ammonia nitrogen, total phosphorus, SS and TOC are 91.8%, 93.8%, 94.7%, 100% and 91.4%, respectively, when the CODc, of original wastewater is 1 100-1 500 mg/L, pH 6.8-7.2, water temperature in hydrolysis process 25-30 °C, HRT 6 h, C/N ratio 60：1, and SBR process reaction time 8 h, temperature 34-38 °C. The effluent water quality can reach the Water Pollutant Discharge Standard in Pulp and Paper Industry （GB 3544- 2008）. Since the microfiltrating membrane has been placed in the biochemical reaction, its membrane pollution is reduced and has certain interception effect on the polluted materials.
