摘要：监测的某化机浆厂每吨浆废水发生量在24～55 m3/t之间变动,高浓化机浆废水经过了沉淀—厌氧—好氧生物处理后,化学需氧量(COD)降至500 mg/L左右,去除了废水中90%的污染负荷。对好氧出水进行了催化氧化试验,探讨了主要处理因素对COD去除率的影响,结果表明:最佳工艺条件pH值为3,H2O2和FeSO4.7H2O用量分别为2和3 mmol/L,COD去除率为86.1%,用空气作催化剂在1.2 L/L用量下可使废水COD去除率再提高5.6个百分点,达90%以上。在工程上,曝气可引自好氧处理的风机房,节省了工程投资。在工厂现场完成放大试验后,设计建造了催化氧化工程,工程运行表明:COD在500 mg/L的好氧出水经过氧化处理后排放水COD降至54 mg/L,生化需氧量(BOD)降至17 mg/L,悬浮固形物(SS)降至32 mg/L,色度降至30倍,完全满足新国家排放标准(GB 3544-2008)。
The effluent from a ehem-mechanical pulp mill, with discharge varying from 24 to 55 m^3/t o.d. pulp, was treated by sedimentation-anaerobic-aerobic stages. COD was reduced down to 500 mg/L, and 90% pollutants were removed. Then the effluent was treated by catalytic oxidation as raw wastewater. During the process, different pH values and usages of H2O2、 FeSO4 · 7H2O were used to investigate and evaluate COD removal of the wastewater. The result indicated that the optimum conditions were H2O2 2 mmol/L and FeSO4 .7H2O 3 mmol/L at pH value 3. Under this condition COD removal is 86.1%. COD removal could reach 90 % which was 5.6% higher that the previous treatment, when air was used as catalyst and its rate was I. 2 L/L. In engineering, the air could be got from ventilator room conveniently with low cost. The pilot test was carried out on site. The running results showed ： after catalytic oxidation, the effluent COD drops to 54 mg/L, BOD is down to 17 mg/L, SS is reduced to 32 mg/L, and chromaticity decreased to 30 times. The performance could meet the new discharge standard（ GB3544- 2008）.
