PRODUCTION OF CULTURE SOIL FOR SEEDLING GROWTH USING DEHYDRATED SLUDGE AS RAW MATERIAL

摘要

PURPOSE:To effectively reuse a sludge by producing a culture soil for seedling growth having high productive value using a dehydrated sludge as a raw material made by dehydrating a sludge, etc., produced in a water purifying plant or accumulated in rivers, lakes, etc. CONSTITUTION:A dehydrated sludge cake is baked at 600-1100 deg.C and a baked product is crushed and added with other culture soil raw materials at need. The baked product or a mixture of the same and other culture soil raw materials is conditioned humidity and granulated to produce this culture soil for seedling growth using the dehydrated sludge as the raw material.
