一、前言炼油厂含油污水的水质随加工原油的性质、加工工艺的不同和企业管理水平而有很大差异,这种差异就引起了采用同一除油处理工艺(隔油、溶气浮选或聚结—过滤)而产生不同的处理效果,甚至同一炼油厂由于水质的变化,处理效果也时好时坏波动较大。为此,从1979～1982年我们对东方红炼油厂各生产车间及总排水的水质进行了较系
I. Foreword The quality of oily wastewater in oil refineries varies greatly with the nature of the crude oil being processed, the different processing technologies and the level of enterprise management. Such discrepancy causes the same oil removal process (oil separation, dissolved air flotation or Coalescence - filtration) and produce different treatment effects, and even the same refinery due to changes in water quality, the treatment effect is also good times and volatility. To this end, from 1979 to 1982, we Dongfanghong refinery production workshop and the total drainage of water quality were more
