摘　　要：研究了用黄铁矿废渣/H2O2体系对造纸废水生化处理出水的处理。该反应为非均相的类芬顿反应,其处理效果良好。通过正交试验得到处理造纸废水各影响因素的影响权重,而后通过单因素试验得到了适宜处理条件,即pH为中性、反应温度为25℃、H2O2用量为15 ml/L、黄铁矿废渣用量为10 g/L、处理时间1 h,COD初始浓度为128 mg/L的造纸废水处理后COD的去除率达到68.06%,出水COD可以达标排放。研究表明,由于多种矿物间的相互作用以及协同催化作用,黄铁矿废渣具有较好的催化活性,pH值影响较小,易于分离沉淀,且能重复利用,可以解决传统反应中pH值调整的问题,黄铁矿废渣利用问题,以及造纸废水达标排放问题。The effluent of papermaking wastewater after biochemical treatment was treated in pyrite slag/H2O2 system,which was Fenton-like reaction,the effluent was well.The influence weights of factors in treating papermarking wastewater were obtained through orthogonal tests,Then the suitable treatment conditions were obtained through single factor tests.That is,pH was neutral,reaction temperature was 25℃,the dosage of H2O2 is 15 ml/L,the dosage of pyrite slag was 10 g/L,the handling time was 1h.When the COD initial concentration was 128 mg/L,68.06% of COD was removed.The effluent COD was less than the wastewater discharge standard.The results show that the pyrite slag has good catalytic activity because of the interaction of various minerals and synergistic catalysis.The influence of pH value on the pyrite slag is small.It is easy to separate and precipitate,and can be reused.It can solve the problems of pH adjustment in traditional reactions,utilization of pyrite slag and discharge of papermaking wastewater up to the standard.
