| 摘 要： | 针对污泥水分高、表面亲水性官能团多、持水性强、难以直接与煤掺混制备水煤浆的特性,进行了添加碱性物质对污泥改性制备污泥水煤浆的研究。结果表明,污泥经NaOH改性后,与煤掺混可以制备出浓度较高、黏度、流动性均好的污泥煤浆。同时发现,选用碱性造纸黑液改性污泥,不仅可以制备出性能好的污泥煤浆,而且可以节约制浆用水、添加剂,减轻了造纸黑液对环境造成的污染。

| Abstract: | The original unmodified sludge can not be mixed with coal to prepare CWM due to its high moisture content,rich surface hydrophilic functional groups and strong water binding capacity. Adopt alkaline matter to modify the sludge. The results show that, modified by NaOH, the sludge can be mixed with coal to prepare high concentration ,favorable viscosity and fluidity sludge CWM. The papermaking wastewater is also an excellent modifier for sludge. It is beneficial to prepare high quality CWM and save water and additive, meanwhile reduce the environmental pollution. |
