FIELD: ecology; environmental management.
SUBSTANCE: method for producing inert soil involves mixing liquid waste with a binding additive and a reagent. The filtrate of a solid municipal waste landfill is used as liquid waste, which is mixed with a reagent, which is aluminum sulfate, in a ratio of 1:0.03, with constant stirring until the resulting foam is destroyed. A binding additive, which is metallurgical slag, is added to the resulting suspension in a ratio of 1:1.2 relative to the initial volume of the filtrate, then stirring is continued for 20 to 30 minutes. The resulting mixture is poured onto a prepared waterproof base and kept until completely dehydrated.
EFFECT: ensuring the joint recycling of two industrial wastes with the production of inert soil.
