摘要
Waste material is treated by mixing it with an aqueous solution of an alkali metal silicate and a silicate setting agent containing polyvalent metal ions to cause the silicate and setting agent to chemically react with each other and convert the mixture into a consolidated chemically and physically stable earth-like material substantially insoluble in water and with its pollutants entrapped. Landfill material and the treated waste material are disposed in contact with each other on land to be filled and in such relation that the leachate from the landfill material will trickle down through the treated waste material.
