Removal of harmful components from inorganic wastes by the chlorination volatilization method using the soil and the mixed salts was developed. CaCl2 was desirable as a chlorination agent because it was able to keep reacting effectively for a long time. The addition of the soil was not necessary when the waste contained high concentration of SiO2. The chlorination treatment was required about 800 to 1000℃, and it depended on the stability of lead in the waste. It is necessary to flow the carrier gas including moderate moisture.

利用土壤和混合盐类，采用氯化挥发法脱除无机废物中的有害成分。CaCl2是一种理想的氯化试剂，因为它能够在较长时间内保持有效反应。当垃圾中含有高浓度的二氧化硅时，不需要添加土壤。氯化处理需要800~1000℃，这取决于废液中铅的稳定性。有必要流动载气，包括中等湿度。
