Method for solidifying calcium arsenate slag cement
The invention relates to a method for solidifying calcium arsenate slag cement, and belongs to the field of solid waste treatment. The method comprises the following steps: mixing calcium arsenate slag with a binder such as asphalt to prepare particles, then mixing the particles with river sand or water disintegrating slag and calcium arsenate particles, and carrying out curing treatment by using cement. The method can realize permanent and stable harmless treatment of the arsenic slag. The method is simple to operate, low in reaction temperature and stable in performance of the generated calcium and arsenic slag, has the advantages of low treatment cost, small dosage, low leaching toxicity and the like, and is very suitable for safe disposal stockpiling and safe landfill of the calcium arsenate slag.
本发明涉及一种砷酸钙渣水泥固化的方法，属于固体废弃物处理领域。本发明通过将砷酸钙渣与沥青等粘结剂混合制成颗粒，再与河沙或水碎渣与砷酸钙颗粒混合，用水泥固化处理。本方法可以实现砷渣的永久、稳定无害化处理。该方法操作简单，反应温度低，生成钙砷渣性能稳定，具有处理成本低、药剂量小、浸出毒性低等优点，非常适用于砷酸钙渣的安全处置堆存和安全填埋。
