INACTIVATION OF LIQUID WASTE MUD AND SOLID WASTE CONTAINING HEAVY METAL DUE TO SULFURIC ACID REDUCING BACTERIA

摘要

Process for the inertization of liquid waste, mud and solid waste, containing sulphates and heavy metals, which comprises a neutralization step of the compounds to be treated and an anaerobic reduction step of the sulphate ion to allow the formation of sulphide ions necessary for the process. A consortium of sulphate-reducing bacteria and lactobacilli is used, with whey as a carbon and nitrogen source.
