Abstract

PURPOSE: To capture and remove harmful heavy metals quickly, inexpensively and effectively by adding polyethylene imines (salts) having dithioic acids groups and sulfur compds. to waste water contg. heavy metals.
CONSTITUTION: A flocculating agent prepd. by mixing compds. added with ≥1 piece of dithioic acid groups or their salts and ≥1 kind of sodium sulfide, sodium polysulfide, sodium hydrosulfide, etc. is added to waste water contg. heavy metals under agitation. The amt. of the addition is about 0.3W1.2 times mole equiv. the contents of the heavy metals in the waste water. The use ratios of the polyethylene imine deriv. and the sulfur compds. are about 1:99W99:1. According to this method, the heavy metals in the waste water are captured thoroughly, and the secondary pollution by the redissolution, etc. of formed sludge is prevented.
