炼油厂污水处理场活性污泥膨胀原因分析和控制措施
|
摘要
A/O活性污泥法是炼油厂污水生化处理常用工艺,由于受来水水量和水质变化的冲击,会造成活性污泥膨胀,影响污水处理场的正常运行。针对某炼油厂污水处理场几次活性污泥膨胀的过程,分析产生原因,采取措施,并提出改进污水处理场的运行建议。
A/O activated sludge process is a common process of sewage biochemical treatment in refineries.The impact of water quality and quantity will cause sludge bulking and affect the normal operation of sewage treatment works. According to the process of several times of activated sludge bulking in a sewage treatment works of a refinery, the causes were analyzed with the countermeasures adopted; more than that, some suggestions about sewage treatment works operation improvement were pointed out.
