Preparation method of composite ceramsite capable of simultaneously preparing biochar and ceramsite
The invention discloses a composite ceramsite preparation method capable of simultaneously preparing biochar and ceramsite, and belongs to the technical field of new materials.The preparation method comprises the steps that industrial solid waste and pretreated wood-based biomass are mixed according to a certain proportion, and the composite ceramsite is fired under a certain atmosphere. The method has the advantages that the cost is low, and the industrial solid waste and the wood-based biomass material are cheap and easy to obtain; (2) the process is simple, the biochar and the ceramsite are simultaneously prepared, the process steps are few, the operation is easy, and the preparation cost is reduced; and (3) the prepared composite ceramsite has the advantages of rich functional groups of biochar and high specific surface area of ceramsite, and can meet the treatment requirements of pollutants in various environments such as wastewater and polluted soil.
本发明公开了一种能同时制得生物炭和陶粒的复合陶粒制备方法，属于新材料技术领域，本发明将工业固废及经预处理的木基生物质按一定比例混合，在一定气氛下烧制复合陶粒。本发明的优点在于①成本低，工业固废及木基生物质材料价廉易得；②工艺简单，生物炭和陶粒同时制备，工艺步骤少，操作容易，降低了制备成本；③制得的复合陶粒同时具备生物炭的丰富官能团和陶粒高比表面积的优势，可以满足废水及污染土壤等多种环境下污染物的处理要求。
