改良型氧化沟-Fenton工艺深度处理废水的故障分析及解决措施

Trouble analysis and trouble shooting in pulping and papermaking wastewater treatment by using modified oxidation ditch-Fenton processss

采用改良型氧化沟-Fenton工艺深度处理制浆造纸废水。介绍了废水处理系统的总体概况和系统中各工序的运行参数;分析了运行中出现的故障,并采取有效解决办法,使系统恢复正常运行,出水满足《制浆造纸工业水污染物排放标准》(GB3544-2008)中各项水质指标的规定。

Pulping and papermaking wastewater was treated by using modified oxidation ditch--the advanced treatment of Fenton system. The overall general situation and operation parameters of each section in the wastewater treatment system were introduced; operational failure was analyzed and effective solution was taken, so the system gradually returned to normal, the discharge can be accordance to The Discharge Standard of Water Pollutants for Pulp and Paper Industry （GB 3544-2008）. Key words： modified oxidation ditch; fluidized bed-Fenton; pulping and papermaking wastewater; operation control; trouble analysis; trouble shooting
