procedure for the production of resources for the creation of an artificial sediment for coverage of polluted sediment

摘要

Formation of artificial sediment comprises mixing precipitation solution with reagent to form precipitate via a chemical reaction. During this reaction a carrier material and a reinforcing material are added to increase sedimentation speed and to bind together the flock formed in order to create an erosion-resistant, stable sediment with the same properties as natural sediment. An artificial sediment can be prepared by flocking an aluminum/silica based precipitation solution with sodium hydroxide whilst adding fine particles of sand and cellulose fibres.
