Title:
METHOD FOR PROCESSING WASTE INCINERATION FLY ASH BY USING BIOGAS RESIDUES
Document Type and Number:
WIPO Patent Application WO/2018/233613
Kind Code:
A1
Abstract:
In the present disclosure, a method for processing waste incineration fly ash by using biogas residues is designed. The method for processing waste incineration fly ash by using biogas residues comprises: digging out fly ash at a polluted site, and transferring the fly ash to a storage yard; laying an impermeable layer in the storage yard, laying a flow guide material at the bottom, laying a mixture layer comprising biogas residues, a carbon source, sulfate, nutritional additives and fly ash on the upper part thereof, and placing a mixture layer comprising a titanium material and a nano-iron material on the upper part of the mixture layer; and in the operating process, irregularly injecting a carbon source solution from the upper part of the storage yard, irregularly collecting leachate into a leachate collection system by means of a flow guide material on the bottom, and then making the leachate flow back to the top of the storage yard for spraying and recharging. By processing the fly ash by using the method, heavy metals are fixed on the storage yard, and dioxin in the fly ash is rapidly degraded.
