Removal of harmful components from inorganic wastes by tchlorination volatilization method using soil and mixed salts

研究了利用土壤和混合盐的氯化挥发法去除无机废物中有害成分的方法。CaCl 2是理想的氯化剂，因为它能够长时间保持有效反应。当废物含有高浓度的SiO2时，不需要添加土壤。氯化处理的温度为800 ~ 1000℃，温度的高低取决于铅的稳定性。有必要使包含适度水分的载气流动。

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.
