A Preliminary Analysis of Comprehensive Utilization and Zero Emission of Wastewater from Domestic Waste Incineration Power Plants

Abstract

This article systematically analyzes the water quality characteristics of various types of wastewater generated by domestic waste incineration power plants, including leachate, domestic sewage, circulating cooling wastewater, and workshop cleaning water. Through practical exploration and technological innovation, a disposal mode combining qualitative treatment and comprehensive utilization is adopted: using clear liquid as circulating cooling water replenishment to achieve resource utilization; Centrifuge, dehydrate, dry and incinerate the sludge for disposal; The concentrated solution is then sprayed back into the furnace or used for lime slurry preparation, converted into fly ash, and safely buried after chelation stabilization treatment. As a result, the entire factory's wastewater ultimately achieved the goals of comprehensive utilization and zero discharge. Finally, taking the Chaonan Municipal Solid Waste Incineration Power Plant (hereinafter referred to as "Chaonan Municipal Solid Waste Power Plant") in Shantou City as a case study, the practical application of comprehensive utilization and zero discharge of wastewater from the municipal solid waste incineration power plant is specifically elaborated.
