摘要
针对目前造纸行业废水生化处理工艺运行效果差、不稳定的问题,采用处理工艺为AO-MBBR-MBR的中试设备处理造纸废水,研究中试设备处理造纸废水过程中的污泥量变化、CODCr和TN去除效果.结果表明:MBBR填料为微生物提供良好的聚集场所,有利于形成体积较大的菌胶团,提高了好氧区污泥浓度.系统运行稳定后,CODCr及TN的去除率均在90％以上,出水CODCr和TN满足《地表水环境质量标准》(GB3838-2002)中的Ⅳ标准.
Abstract
In view of the poor and unstable operation effect of wastewater biochemical treatment process in papermaking industry,the pilot equipment of AO-MBBR-MBR process was used to treat papermaking wastewater,and the sludge volume change,CODCr and TN removal effect in the process of wastewater treatment by pilot equipment were studied.The results showed that MBBR fillings provided a good gathering place for microorganisms,which was conducive to the formation of larger bacterial colonies and increased the sludge concentration in the aerobic zone.After a stable operation,the removal rates of CODCr and TN were both above 90％,and the effluent CODCr and TN met the Ⅳ standard of the Surface Water Quality Standard(GB3838-2002).
