含油污泥与污水污泥耦合炭化特性研究
Research on Coupling Carbonization Characteristics of Oil Sludge and Sewage Sludge
摘要
Abstract
From the perspective of realizing comprehensive utilization and collaborative resource utilization of multi-source sludge,using zinc chloride(ZnCl2)as activator,the carbon yield,pore and functional group distribution characteristics of oily sludge,sewage sludge and sludge-based activated carbon obtained by mixing them in different proportions before and after activation were studied,the coupling effect of the two types of sludge was analyzed,and the optimal mixing ratio was selected,guiding the comprehensive utilization of sludge.The results showed that the sludge based activated carbon had certain pore characteristics,and the activation of ZnCl2 on the sludge based activated carbon was better than the micro-pores.According to the pore and function-al characteristics,the mixing of oily sludge and sewage sludge can improve the functional index of activated car-bon,and the mixing ratio of oily sludge and sewage sludge was 6∶4.Infrared characterization showed that there were more peak strong responses of oxygen-containing functional groups from 900 to 1 150 cm-1,and the C=O response was more obvious around 1 610 cm-1.It can be seen from the analysis that ZnCl2 activation and the mixed carbonization process of multi-source sludge can optimize the organic structure of sludge carbonization and increase the types of oxygen-containing functional groups.The activation of ZnCl2 can retain the-OH in activa-ted carbon,improve the function of the carbon product,and have practical guiding significance for the compre-hensive utilization and collaborative resource recovery of oily sludge and sewage sludge.关键词
