摘　　要：豆制品废水是一种较难处理的高浓度有机废水,而传统的SBR方法仍然有可以改进之处。通过对PAC-SBR系统处理豆制品废水的研究,发现木质PAC对豆制品废水中COD的最大理论吸附量为13.3 g/g,其吸附能力强;SBR中投加木质PAC,可显著提高系统的处理效能,在适宜投加量400 mg/L下,出水COD和TKN浓度较未添加木质PAC的SBR系统分别降低25.12%和17.14%,且污泥的沉降性能还得以改善。Currently,the high organic concentration wastewater from bean production plant is difficult to be treated,but traditional SBR still needs further improvement.Soybean processing wastewater treatment by powder activated carbon-sequencing batch reactor system（PAC-SBR）was investigated.The study showed that maximum theoretical adsorption quantity of PAC for COD reached to 13.3 g/g.In addition,adding PAC into SBR could remarkably improve processing efficiency of the system,the COD and TKN concentration of the effluent of the PAC-SBR decreased by 25.12% and 17.14%,respectively,when the PAC addition was 400 mg/L.Meanwhile the sludge sedimentation was improved too.
