摘　　要：制浆中段废水采用生化处理后往往不能达标排放,需要深度处理。本文研究Fe0-H2O2体系深度处理制浆中段废水的影响因素,以期为制浆中段废水的深度处理提供一种经济有效的工艺。研究了反应的初始pH值,铁粉加入量,双氧水的加入量以及反应时间对Fe0-H2O2体系深度处理制浆中段废水的影响,结果表明,初始pH为3,铁粉加入量为1.5g/L,双氧水加入量为0.32mL/L,反应时间为40min时,CODCr去除率可达79.21%。The mid - stage pulping effluent often cannot satisfy the discharge standard after biodegradation, so ad- vanced treatment was needed. In this paper, the influence factors on mid -stage pulping effluent treatment by Fe0 -HEOESystem were studied, expecting to provide an economic and efficient technology for the advanced treatment of mid - stage pulping effluent. Effects of initial pH, iron dosage, hydrogen peroxide dosage and reaction time on mid - stage pulping effluent treatment by Fe0 - H2O2 system were studied. The results indicated that the optimum conditions were： the initial pH was 3, the iron dosage was 1.5g/L, the hydrogen peroxide dosage was about 0.32 mL/L, under which CODCr removal rate was up to 79.21% after 40min.
