Method for realizing low-carbon harmlessness of titanium gypsum and producing porous matrix
The invention belongs to the technical field of titanium gypsum utilization, and particularly relates to a method for realizing low-carbon harmlessness of titanium gypsum and producing a porous matrix, and the porous matrix is obtained by carrying out flash evaporation drying treatment on the titanium gypsum added with ethanol. The treated titanium gypsum crystals are damaged and disintegrated to form porous matrixes with different sizes, and active substances harmful to the environment in the original titanium gypsum in the matrixes are greatly reduced, so that the original alkaline condition of the titanium gypsum is changed into the condition with the pH value close to neutral; the obtained porous matrix provides a rich inhabiting site for microorganisms, the inhabiting microorganisms can keep active for a long time, as time goes on, microorganisms beneficial to plant growth in the matrix are gradually increased, and microorganisms beneficial to plant growth are reduced; according to the method, low-carbon harmlessness and stabilization of the titanium gypsum are achieved through the one-step method, the whole process is low in carbon and free of secondary pollution, and the field of utilization of the titanium gypsum is expanded.
本发明属于钛石膏利用技术领域，具体涉及一种实现钛石膏低碳无害化及生产多孔基质的方法，通过对加入乙醇的钛石膏进行闪蒸干燥处理即得。处理后的钛石膏晶体破损、崩解，形成大小不一的具有多孔的基质，基质内原钛石膏中的对环境有害的活性物质大大减少，使钛石膏由原来的碱性条件转为pH值接近中性的条件；获得的多孔基质为微生物提供了丰富的栖息场地，且使得栖息的微生物能够长时间保持活性，随着时间的推移，基质中对植物生长有益的微生物逐渐增多，而无益的微生物减少；本发明采用一步法实现了钛石膏的低碳无害化、稳定化，整个过程低碳、无二次污染，为钛石膏的利用拓展了领域。
