Abstract

PURPOSE:To detoxify the heavy metal contained in dust and sludge, by reacting polyethyleneimine, carbon disulfide and sodium hydroxide with dust and a sludge and further adding sodium diethyldithiocarbamate to the reaction mixture to mix the same therewith. CONSTITUTION:Carbon disulfide is added to and kneaded with ethyleneimine an caustic soda, sodium diethyldithiocarbamate, sodium sulfide and water are subsequently added to the kneaded mixture and sodium thiosulfate is further added thereto to perform stirring. The obtained liquid composition is added to dust and sludge containing noxious heavy metal ions to be kneaded therewith sufficiently. By this method, the heavy metals contained are sealed-up and the re-elution thereof is prevented.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a drug that immobilizes heavy metals eluted from various types of dust sludge and sludge containing toxic heavy metals.

The dust, sludge, and sludge contain heavy metals such as total mercury, lead, cadmium, arsenic, zinc, manganese, and copper. Therefore, at present, these wastes are solidified using a cement-based solidifying agent. However, fixing these heavy metals below the standard value according to the Prime Minister's Office Ordinance J, which stipulates the standards for determining standards for hazardous industrial waste, involves costs that cannot be ignored, and the increase in volume in particular means securing future landfill sites. Increasingly strict measures are required to deal with these problems.The biggest drawback of cement solidification is the problem of re-elution.

Therefore, the present invention aims to minimize the volume of the treated material, scientifically sequester the heavy metals contained therein, and prevent re-elution. This will be explained in detail below.
