- Abstract:
- With the severe environmental protection accountability situation and the people’s expectations for a better life in recent years, municipal sludge, the by-product of urban sewage treatment, has attracted more and more attention. It is a more urgent task to rationally plan the scale of construction projects, formulate economic and technological routes, and achieve sustained and stable operation. This paper reviews the construction of centralized sludge treatment facilities in the past ten years among 36 of under the central government municipality cities, provincial capital cities, and national plan single cities in China. The technical characteristics and application of the operational projects, projects to be built and operated were analyzed and compared with the similar projects in the world. China’s current sludge treatment center projects are generally in small scale and are facing the challenges of sludge terminal disposal and environmental quality improvement. So it is urgent to be upgraded. The concept of the whole life cycle should be used to summarize the operational experience and operating costs of the completed projects promptly, and provide a reference for the future construction of sludge treatment and disposal projects. The construction of centralized sludge treatment centers should be accelerated, and the advantages of intensification should be brought into compensate for the rigid gap in sludge treatment and disposal. For cities that are constrained by economic conditions, it is recommended to formulate a phased implementation plan, make overall planning and advancement, and rationally arrange in project land occupation and regional planning.
