Abstract: The sludge produced by urban drinking water treatment plants has a high yield, low organiccontent, and a high risk of inorganic pollution. Its green and low-carbon treatment, as well as resourceutilization, has become urgent issues in achieving the " dual-carbon" goals in China's water supply in⁃dustry. This paper discusses and analyzes national industry policies and the characteristics of sludgefrom drinking water treatment plants, and summarizes the treatment methods and development trends inresource utilization. Currently, commonly used treatment methods for drinking water treatment plantsludge include water body discharge, municipal sewage discharge, and landfilling, which present envi⁃ronmental risks, facility clogging, land occupation, and significant carbon emissions. Based on thecharacteristics of sludge from urban drinking water treatment plants, potential methods for resource uti⁃lization include the production of synthetic adsorption materials, coagulation / precipitation materials,regenerated salt materials, construction materials, and agroforestry materials. Breaking through theaforementioned key technologies to realize the transformation of drinking water treatment plant sludgefrom " treatment" to " resource utilization" will play a crucial role in promoting the green and low-car⁃bon operation of China's urban water supply industry.
