Based on the main problems existing in sludge treatment and disposal in China, this paper gave a detailed interpretation of the Implementation Plan for Sludge Harmless Treatment and Resource Utilization jointly issued by the National Development and Reform Commission, the Ministry of Housing and Urban-Rural Development of the Peoples Republic of China and the Ministry of Ecology and the Environment of the Peoples Republic of China. The sludge treatment in China has problems as follow：sludge quality is poor and is difficult to treat; the work starts late, the capital investment is not in place, and the handling capacity is insufficient; the land use is limited, and the sludge outlet has not been completely opened. Under the background of “Carbon Peaking and Carbon Neutrality”, sludge treatment and disposal in China should follow the basic principles of “comprehensive consideration, adaptation to local conditions, government-led, market operation, stable and reliable, green and low-carbon”, standardize sludge treatment methods, actively promote sludge land use, reasonably reduce the landfill scale, orderly promote sludge incineration alone or in coordination, and increase the promotion of sludge energy and material recycling. For sludge treatment facilities, the efficiency of existing facilities should be improved and the incremental construction should be done well, and the process management should be strengthened and the safeguard measures should be improved. For sludge treatment, it is necessary to take harmless treatment as the goal and resource utilization as the means to complement the shortcomings, and gradually form a complete chain of theories, technologies, equipment, policies, standards and price systems for sludge safe treatment and resource utilization, so as to promote the healthy development of the industry.
