采用微波热解技术,通过改变微波功率、热解温度、气体和固体停留时间、添加催化剂,探究印染污泥热解的特性.采用元素分析、扫描电镜(SEM)、BET比表面积仪、X射线荧光光谱仪(XRF)、X射线衍射仪(XRD)和电感耦合等离子体质谱仪(ICP-MS)对印染污泥和泥炭进行了分析.实验结果表明,随着温度的升高,泥炭产率逐渐降低,750℃时降到63.87%(质量);气体产率随温度逐渐增加.添加CaO和Fe,泥炭产率增加,不可凝气体中CO2含量减少,H2、CO和CH4含量增加,最大H2含量达64.17%.随着热解温度的升高,泥炭中C、H、N元素含量逐渐降低,S含量有所升高.热解温度在550℃时,泥炭的比表面积达到最大值91.9 m2·g-1.经微波热解后,污泥中的重金属符合农业排放标准的要求.“,”The paper investigated pyrolysis of textile sludge in a moving bed pyrolyser under microwave irradiation. Microwave power, temperature, gas and solid residence times, and catalysts were studied. Elemental analysis, scanning electron microscopy (SEM), BET surface area analysis, X-ray fluorescence spectroscopy (XRF), X-ray diffraction (XRD) and inductively coupled plasma mass spectrometry (ICP-MS) were conducted and analyzed. It showed that the sludge char (SC) yield decreased and non-condensable gas yield increased as temperature increased. At 750℃, the SC yield was 63.87%(mass). Addition of CaO and Fe increased SC yield, and the H2, CO and CH4 contents, and decreased CO2 content in the non-condensable gas. Maximum H2 content was up to 64.17%. The contents of C, H and O in SC decreased as temperature increased, while S content increased. The BET surface area reached the maximum at 550℃, which was consistent with the SEM observation. The ICP-MS results showed that the heavy metals in SC met the requirements of emissions standards in China. The moving bed pyrolyser under microwave irradiation provided a promising prospect to efficiently treat and dispose TS.
