摘要: 为了天然橡胶胶乳加工废水的生产回用，采用EGSB-BF生物膜-混凝组合工艺深度处理该废水，对工艺运行的稳定性和处理效果进行了研究。EGSB的HRT为36 h，pH值为6.8~7.5，温度为（35±1）℃，BF生物膜的HRT为48 h，DO浓度为2~4 mg·L-1，硝化液回流比为150%，混凝沉淀深度处理生化尾水，混凝剂优选为硫酸铁，浓度为80~100 mg·L-1，COD、NH4+-N、TP、色度和SS去除率分别为90%~99.4%、91%~100%、93%~98.5%、92%和96%，其出水达到排放及橡胶生产用水的回用要求。采用该工艺深度处理天然橡胶胶乳加工废水，具有启动时间短、抗冲击能力强、运行稳定等优点，产水达到了橡胶加工生产回用的水质标准。

Abstract: To reuse natural rubber latex production processing wastewater, an EGSB-BF biofilm-coagulation process was used as an advanced treatment step, and the operation stability and treatment ability of the process were analyzed. The HRT of the EGSB was 36 h, the pH was 6.8~7.5, and the temperature was (35±1)℃. Furthermore, the HRT of the BF biofilm was 48 h, the DO concentration was 2~4 mg·L-1, and the nitrifying liquid reflux ratio was 150%. Coagulation sedimentation was used for the advanced processing of the biochemical tail water, with 80~100 mg·L-1 iron sulfate used as the coagulant. Finally, the removal rates of COD, NH4+-N, TP, chromaticity, and SS were 90%~99.4%, 91%~100%, 93%~98.5%, 92%, and 96% respectively, and the effluent satisfied the emission and recycling requirements for natural rubber latex production processing. The process has numerous advantages, such as a short start time, impact resistance, stable operation of the deep processing of natural rubber latex processing wastewater, and the production water satisfied the water quality standard for rubber production reuse.
