METHOD OF DETOXIFYING HARMFUL SUBSTANCE, WASTE DISPOSAL SITE, AND PAVED ROAD

摘要

A method of detoxifying harmful substances released from wastes and waste incineration ash or from molten slag, etc., in which the diffusion of the harmful substances can be properly prevented at low cost without imposing any burden on the environment.  Also provided are a waste disposal site and a paved road. A water-permeable clay mineral is disposed so as to be close to and/or in contact with harmful substances, such as heavy metals and organic pollutants, released from wastes and waste incineration ash or from molten slag, etc. so that the harmful substances come into contact with the water-permeable clay mineral and are thereby adsorbed onto the water-permeable clay mineral.  Thus, the harmful substances are adsorbed and fixed.  By mixing and/or kneading a water-permeable clay mineral with wastes or waste incineration ash, harmful substances are more effectively adsorbed and fixed onto the water-permeable clay mineral.
