含油污泥调质-三相分离减量化工艺方法研究
|
摘要
为实现对含油污泥进行资源回收的同时降低其产生量与最终处置难度,采用调质-三相分离工艺进行减量化处理。研究了破乳剂与絮凝剂种类与用量,加热温度、离心转速与离心时间3个工艺参数对油田清罐底泥和炼厂污水处理厂底泥的减量化效果。实验结果表明,破乳剂与絮凝剂的最佳组合为P-A(1%)+CPAM(1. 5%),加热温度、离心转速、离心时间分别不低于80℃、4 000 r/min和10 min,分离后出泥中的含固率可超过40%。
In order to realize the recovery of oil sludge and reduce its production and the difficulty of final disposal,the conditioning-three phase separation method could be used for the quantitative reduction processing of oil sludge. The effects of agent type and dosage,heating temperature,centrifugal speed,centrifugal time on the reducing effect of oil sludge were studied in detail. Results showed the best agent combination was P-A( 1%) + CPAM( 1. 5%). Heating temperature,centrifugal speed and centrifugal time should be no less than 80 ℃、4 000 r/min and 10 min. The solid content of sludge after separation could be more than 40%.
