| 摘 要： | 通过研究罐底油泥的理化性质,开发了适于处理罐底油泥的系列工艺:先采用调质技术提高罐底油泥流动性;再采用超声破乳降低油泥稳定性,改善油泥分离性能;最后采用卧式离心机对油泥进行离心分离处理.在复合型清洗剂加入量为800 mg/L、超声温度为60℃、超声功率为12 kW、超声时间为25 min、离心温度为60℃、絮凝剂加入量为600 mg/L、离心机转速为2200 r/min的条件下,系统稳定运行9d,离心机出口泥中含油率低于2.00％,水中悬浮固体质量浓度低于170 mg/L,达到了对罐底油泥进行除油的目的. |

| Abstract: | Based on the research of physical and chemical properties of tank bottom oily sludge,a series of processes for tank bottom oily sludge treatment were developed as follows:first,improving the fluidity of tank bottom oily sludge by conditioning technology;second,reducing the oily sludge stability and improving the sludge separation property by ultrasonic demulsification;Finally,separating oil and water from the oily sludge by horizontal centrifuge.Under the conditions of composite cleaning agent dosage 800 mg/L,ultrasonic temperature 60 ℃,ultrasonic power 12 kW,ultrasonic time 25 min,centrifugalization temperature 60 ℃,flocculant dosage 600 mg/L,rotational speed 2 200 r/min and running time 9 d,the oil content of the sludge of the centrifuge export is less than 2.00%,the SS in the outlet water is less than 170 mg/L,and the purpose of oil-removal of the tank bottom oily sludge is achieved. |
| Keywords: | tank bottom oily sludge conditioning ultrasonic emulsion breaking centrifugation solid waste waste treatment |
