摘　　要：采用复合式絮凝床对制浆中段废水进行预处理，探讨了影响CODCr去除率的各种因素，得出了最佳工艺参数；比较了复合式絮凝床处理后生化和深度处理效果及运行费用。结果表明，复合式絮凝床作为预处理时，CODCr去除率高达45．6％；与自然沉降和混凝沉淀相比，废水的生化性分别提高了10．4％和7．5％，高达84．3％；总的运行费用分别节省1．85元／t水和1．16元／t水，仅为2．79元／t水。The factors affecting on the removal of CODCr was investigated in treating the papermaking mideourse wastewater by the Combined Elextr-Floculation Reactor. The optinmal operation condition was obtained. Compared the effects of biochemical treatment and advanced treatment＇ with operating costs after the Combined Elextr-Floeulation Reactor Treatment, the results show that removal rate of CODcr up to 45.6% ; Compared with natural settling and coagulation, wastewater biodegradability is up to 84.3% , increasing 10.4% and 7.5% , respectively ; Total operating costs of a ton of water are only 2.79 % , saving 1.85 % and 1.16 % , respectively.
