【摘要】：对石化企业污水处理厂含油污泥脱水性能进行研究,首先使用石油醚对其进行油水分离处理,真空抽滤后,测试滤饼的含水率,以含水率作为判别指标.探究生物质、臭氧和超声调理3种方式,单一及复合调理对污泥脱水性能的影响.结果表明:3种方式单一调理最佳参数,先进行臭氧化,臭氧的最佳投加量为0.1g/g,滤饼含水率为82.45%;再进行超声处理,28kHz时间超声波作用最佳为2min,滤饼含水率为74.61%;生物质与污泥干物质量比为2.5%时,滤饼含水率为62.7%;复合调理参数为臭氧投加量0.1g/g,超声波时间2min,生物质与污泥干质比为2%时,滤饼的含水率达到59.76%.复合调理效果优于单一调理,调理后污泥能够自持燃烧.
[Abstract]:The dewatering performance of oily sludge in petrochemical wastewater treatment plant was studied. Firstly, oil and water were treated by petroleum ether. After vacuum filtration, the moisture content of filter cake was measured, and the moisture content was used as the discriminant index. The effects of biomass, ozone and ultrasonic conditioning on sludge dewatering were investigated. The results show that the best parameters of the three ways are single conditioning, and the ozonation is carried out first. The optimum dosage of ozone is 0.1 g / g, the moisture content of filter cake is 82.45; the best time of ultrasonic treatment is 2 minutes, and the moisture content of filter cake is 74.61; when the ratio of biomass to dry sludge is 2.5, The water content of filter cake was 62.7, the compound conditioning parameters were ozone dosage 0.1 g / g, ultrasonic time 2 min, biomass to sludge dry matter ratio 2, the moisture content of filter cake reached 59.76%. The effect of compound conditioning is better than that of single conditioning, and the sludge can burn on its own after conditioning.
