Treating and curing method before scrapped SCR denitration catalyst burying
The invention provides a treating and curing method before scrapped SCR denitration catalyst burying. The treating and curing method is characterized by comprising the following steps: (1) making a mould for casting concrete through steel plates; (2) smashing scrapped catalyst through a crusher, and then grinding the scrapped catalyst into scrapped catalyst fine powder through a ball mill; (3) mixing the scrapped catalyst fine powder, Portland cement, sand and water, and fully stirring into concrete to be poured into the mould in the step (1); (4) demoulding the concrete after 3-4 h; (5) placing the demoulded concrete cube blocks in single layer, spraying water once every two hours, and covering with a straw mattress to realize moisture retention and maintenance; (6) when the strength of the concrete cube blocks is not less than 30 mpa, conducting plastic package respectively with thick plastic cloth and then burying, wherein the concrete comprises the following ingredients in parts by weight: 10-15 parts of Portland cement, 60-80 parts of sand, 10-15 parts of scrapped catalyst fine powder and 10-15 parts of water. The method is relatively efficient and environment-friendly in treating the scrapped catalyst.
