摘  要:活性污泥与生活垃圾焚烧飞灰日益增多,其环境无害化处理与处置已成为当前亟待解决的问题。生物炭具有吸附重金属的能力,已实际应用于修复土壤重金属污染。以活性污泥为原材料制备的生物炭协同处理生活垃圾焚烧飞灰,在减少活性污泥及飞灰产量的同时,能大量降低处理成本。本文介绍了污泥活性炭的制备方法及其吸附重金属的原理,分析了污泥活性炭吸附垃圾焚烧飞灰中重金属的可行性。Activated sludge and domestic waste incineration fly ash are increasing,and their environmentally sound treatment and disposal have become an urgent problem to be solved.Biochar has the ability to adsorb heavy metals and has been practically used to repair heavy metal pollution in soil.Biochar prepared with activated sludge as raw material can co-process domestic waste incineration fly ash,which can greatly reduce the processing cost while reducing the output of activated sludge and fly ash.The preparation method of sludge activated carbon and the principle of adsorption of heavy metals were introduced,and the feasibility of sludge activated carbon to adsorb heavy metals in waste incineration fly ash was analyzed.
