摘　　要：油泥是石油化工行业主要的固体废弃物之一,文章利用海水洗涤处理落地油泥,考察表面活性剂的用量、洗涤温度、搅拌速度等操作条件对油泥脱油率的影响,并对比了海水与淡水洗涤油泥的脱油效果.结果表明,与淡水洗涤相比,海水洗涤的脱油效果较好;在表面活性剂TX-10（任基酚聚氧乙烯醚）用量0.75 g/30 g油泥、海水用量150 mL/30g油泥、洗涤温度60℃、搅拌转速为180 r/min、洗水pH 8～9、搅拌30min的操作条件下,油泥的脱油率可达84.9％,在上述实验条件不变下,经两次洗涤处理后油泥含油量为0.17％,达到排放要求.Oily sludge is the one of the main solid wastes in the petrochemical industry, the article adopted the method of the seawater washing. By seawater and freshwater comparative experiments, the result indicates that, the deoiling effect of seawater washing is better; Study the effect of experimental conditions： surfactant concentration, washing temperature, stirring speed and ect, on the removal rate of oily sludge, the removal rate of 30 g oily sludge reached 84.89 % under the operating conditions： 0.75 g of the TX-10 concentration, 60 ~C of the treatment temperature, 8 to 9 of the pH value, 150 mL of the seawater, and 180 r/min stirring speed for 30 minutes. At the optimum experimental conditions, after twice washing treatment, the oil content is reduced to 0.17 % and that can meet the emission requirements.
