摘要:: 采用膜生物反应器（MBR）处理模拟焦化废水，驯化活性污泥，并考察水力停留时间（HRT）和溶解氧（DO）浓度等工艺参数对污染物去除效果的影响，构建互联网监控系统对工艺装置的运行进行监测与控制。结果表明，经过70 d的培养驯化，MBR中的MLSS增长至2.3 g/L，污泥沉降比（SV30）由1%增长至34%并保持稳定，COD、UV₂₅₄等出水指标稳定达标。在进水COD为810 mg/L、UV₂₅₄为5.0 cm-1的条件下，当HRT为10 h、DO为3.0~3.5 mg/L时，COD和UV₂₅₄去除率分别可达到100%和91%。互联网监测数据显示，出水COD与氧化还原电位（ORP）具有较强相关性，为此采用多元线性回归方法提出了ORP预测模型，该模型准确度较高、稳定性较好，可用于该工艺运行过程的管理，实现远程控制。

Abstract:: The membrane bioreactor (MBR) was applied to treat the simulated coking wastewater and domesticate the activated sludge. The effects of the process parameters such as hydraulic retention time (HRT) and dissolved oxygen (DO) on the removal of the pollutants were investigated, and an internet monitoring system was constructed to monitor and control the operation of the equipment. After 70 days of cultivation and domestication, the MLSS in the MBR increased to 2.3 g/L, the sludge volume (SV30) increased from 1% to 34% and then tended to be stable, and the water quality index of the effluent such as COD and UV₂₅₄ were stable and reached the national discharge standard. Under the conditions of influent COD of 810 mg/L and UV254 of 5.0 cm-1, the removal efficiencies of COD and UV₂₅₄ were 100% and 91%, respectively, when the HRT and DO were 10 h and 3.0-3.5 mg/L. The internet monitoring data showed that the COD and oxidation-reduction potential (ORP) in the effluent were strongly correlated with each other. Therefore, a model for predicting ORP was proposed by using multiple linear regression methods. The model had higher accuracy and good stability, and could be used to manage the process and realize remote control.
