Abstract

Abstract:

In order to effectively reduce the content of polymer in polymer-containing oily sludge and reduce the influence of polymer on the subsequent treatment of polymer-containing oily sludge, ultrasonic, depolymerizing agent and cooperative processing technique were adopted to treat the polymer-containing oily sludge. The effects of ultrasonic time, ultrasonic frequency, depolymerizer dosage and other parameters on depolymerizing and deoiling effects were studied. The experimental results show that the amount of polymer-containing oily sludge was reduced by about 60% and the oil removal rate was about 75% after centrifugal separation under the condition of ultrasonic frequency of 20kHz and ultrasonic time of 5min, but the effect of ultrasonic on depolymerization was not obvious, ultrasonic was suitable for the reduction treatment of polymer-containing oily sludge. After depolymerizing agent treatment, the degradation rate of polymer in oily sludge reached up to 96.7%, and the bottom sediment after centrifugal separation was loose and the water phase was clear. After ultrasonic and depolymerizing agent cooperative processing treatment, the degradation rate of polymer in oily sludge reached up to 97.5%, while the oil content of solid residue after pyrolysis was lower than 0.3% under the condition of ultrasonic frequency of 20kHz and ultrasonic time of 5min, depolymerization agent dose of 4000mg/kg and pyrolysis temperature of 550℃. It is shown that the cooperative processing technique of ultrasonic and depolymerizing agent met the requirements of sludge resource treatment.

Key words: ultrasonic, depolymerization, polymer-containing oily sludge, collaborative treatment, pyrolysis, centrifugation, waste treatment

摘要：

为了有效降低含聚油泥中聚合物的含量，减少聚合物对含聚油泥后续处理的影响，采用超声波、解聚剂以及两者协同的方法对含聚油泥进行处理，研究了超声时间、超声频率、解聚剂加量等参数对解聚和除油效果的影响。实验结果表明，含聚油泥在超声频率20kHz、超声时间5min的处理条件下，离心分离后减量60%左右，除油率75%左右，但超声波对聚合物降解效果不明显，适用于含聚油泥的减量化处理；含聚油泥经过解聚剂处理后，聚合物降解率最高可达96.7%，离心分离后底泥疏松，水相澄清；含聚油泥经过超声波与解聚剂协同处理后，聚合物降解率最高达到97.5%，在超声频率20kHz、超声时间5min、解聚剂量4000mg/kg、热解温度550℃的处理条件下，热解后固渣含油率低于0.3%，满足油泥资源化处理的要求。
