Abstract:

The furfural wastewater is kind of highly concentrated organic wastewater which is difficult to be treated. This process of micro-electrolysis -neutralization -coagulation -UASB -optional anaerobic - biological contact oxidation - biological activated carbon has been used for treating furfural wastewater. The industrial experiments indicate that the effluent water can reach the 2nd grade of discharge standard of “Liaoning Province Wastewater and Gas Discharge Standard”（DB 21—60—1989）. The application of carbide slag reaches the goal that controlling the waste by waste， and the method has a certain economic significance. It can also be a reference for the treatment of other kinds of wastewater.

Key words: furfural wastewater, micro-electrolysis, upflow anaerobic sludge bed, biological contact oxidization

摘要：

糠醛废水属于难处理的高浓度有机废水,工程采用微电解—中和—混凝—UASB—兼性厌氧—生物接触氧化—生物活性炭工艺处理糠醛废水。工业实验表明,出水达到《辽宁省污水与废气排放标准》(DB21—60—1989)二级排放标准。电石渣的应用起到了以废治废的目的,具有一定的经济意义,该工艺对其他废水的处理有一定的借鉴作用。
