Process for treating liquids wastes possessing a strong acidity

摘要

Waste material having a pH not exceeding 2, and which have previously caused a serious disposal problem, are converted into stable, solid, useful, non-polluting products by first mixing the waste material with fly ash using about 30 to 260 parts of weight of ash for 100 parts of waste material, then neutralizing the resultant mixture using lime or calcium carbonate containing materials, next adding a calcium containing binder such as lime or Portland cement, and then solidifying the resultant mixture.
