Abstract:
The combined process of physiochemical pretreatment, anoxic/aerobic and improved high-density aerated biological fluidized bed is adopted to treat waste lubricating oil reclaimed wastewater, with treatment capacity of 150 m3/d. The operation results show that the average removal rates of COD, ammonia nitrogen, and total nitrogen are 98.7%, 99.9%, and 94.7%, respectively. The effluent quality can meet the criteria of the third level in the Integrated Wastewater Discharge Standard (GB 8978-1996) and the treatment plant compliance standards for the second urban sewage plant in Xuyi County. By merits of strong resistance to impact load and convenience to maintain, this efficient and stable process is also cost?effective with a direct operating cost of 21.68 yuan/m3.
