Hybrid double effect sludge rapid solidification solidification agent and rapid solidification method of sludge using the same

摘要

Problem solving of conventional waste gypsum and PS ash mixture processing is solved.Construction sludge expected to occur in the futureIt is a drug that rapidly solidifies sludge such as sewage sludge residue sludge and dredging sludgeAqueous solution of silica mixed with silica aqueous solution and dilute sulfuric acid or sulfuric acid bandsTwo kinds of gypsum gypsum containing crystal water of gypsum gypsum without constant quantity were made to be the main agent of the rapid solidification.It is a hybrid double effect sludge quick solidification treatment agent using waste gypsum as PS.In addition, fluorine generation inhibitor is added.OtherwisePhosphate necessary for plant growthPotassiumThe recycled soil solidified with the addition of the nutrient which mixes at least a kind of ammonium sulfateProblem to be solved: to provide a rapid sludge solidification treatment agent capable of reuse and reduction in a simple and efficient natural environment and a rapid sludge solidification method using the same.SludgeOnly the water is discharged from the top and processed.Reduce sludge handling capacitySludge solidifying agent for solidification and solidification of sludgeWaste gypsum and PS ash are used as the side agent.It is a hybrid double effect sludge treatment agent of the hybrid double effect which uses two kinds of silica aqueous solution mixed with sulfate or dilute sulfuric acid in the aqueous solution of silica and the neutral solidifying agent of the semi gypsum gypsum.Add another fluorine inhibitorIn addition, it is phosphoric acid of the large nutrients ofPotassiumA sludge rapid solidifying agent characterized by mixing at least one of a stream of ammonium sulfate.No selection
