一种纱管纸生产废浆液的处理回收方法
摘要：
本发明公开了一种纱管纸生产废浆液的处理回收方法，属于环境工程技术领域。本发明采用基于好氧颗粒污泥技术的两级纱管纸生产废浆液处理回收工艺具有药剂投加少，占地面积小，运行周期短，运行调控容易的特点。通过吸附段好氧颗粒污泥处理高负荷废浆液，可以实现废浆液中纤维类物质的高效浓缩，回收资源类物质；通过生化段好氧颗粒污泥处理吸附段出水，可以保证出水稳定达标排放。采用本发明方法，吸附段好氧颗粒污泥对纤维类物质和蛋白质类物质的吸附量分别达到710和140mg/gMLSS，生化段出水COD，NH4‑N，TP和SS浓度分别为98，4.1，0.8和100mg/L，COD和SS的去除率分别达到98.8％和96.2％，出水满足相应排放标准。
摘要（英）：

The present invention relates to the technical field of environmental engineering, and particularly relates to a method for treating and recycling waste slurry in bobbin paper production. The present invention employs aerobic granular sludge technology-based two-stage process of treating and recycling waste slurry in bobbin paper production, and has features of low agent feeding, small floor space occupation, a short operating cycle, and easy controllability. By treating a high-load waste slurry in an adsorption section having aerobic granular sludge, fibrous materials in the waste slurry can be concentrated efficiently and resource substances can be recycled. By treating water discharged from the adsorption section with aerobic granular sludge in a biochemistry section, a water release can be guaranteed to stably meet the standard. By employing the method, the amounts of the fibrous materials and proteins adsorbed by the aerobic granular sludge in the adsorption section reach 710 mg/g MLSS and 140 mg/g MLSS respectively, the concentrations of COD, NH4-N, TP and SS of water released from the biochemistry section are 98 mg/L, 4.1 mg/L, 0.8 mg/L and 100mg/L respectively, and the removal rates of COD and SS reach 98.8% and 96.2% respectively, enabling water release to meet a corresponding release standard.
