摘　　要：含油污泥是石化行业的主要污染物,在固体废弃物中占比很大,不经处理排放会危害周边环境,因此,对含油污泥无害化处理非常重要。清洗法是油泥处理成本较低的方法,研究采用化学清洗法,优化影响油泥清洗效率的参数。确定清洗温度、固液比取值范围,考察单独变量作用对含油污泥残油率的影响。单因素变量对含油污泥残油浓度有显著影响。化学法处理含油污泥最佳工艺条件为化学药剂浓度0.84 g/L,测定值与预测值相对误差为2.78%。Oily sludge is the main pollutant in petrochemical industry, accounting for a large proportion of solid waste. Untreated discharge will harm the surrounding environment, so oil sludge harmless treatment is very important. The chemical cleaning method was used to optimize the parameters affecting the sludge cleaning efficiency. Determine the range of cleaning temperature and solidliquid ratio, and the effect of single variable on residual oil percentage of oily sludge was investigated. The single factor variable has significant influence on the residual oil concentration of oily sludge. The optimal process condition of chemical treatment of oily sludge is chemical concentration 0.84 g/L, and the relative error between measured value and predicted value is 2.78%.
