摘要
污泥资源化不仅可以减少环境污染,还可以实现资源的再利用,促进经济可持续发展。深入探索污泥的高效资源化路径、不断增强污泥资源化利用水平,是污水处理厂践行绿色、循环发展理念的重要举措。根据污泥的理化性质,综述了城镇生活污水处理厂污泥资源化综合利用的不同路径,主要包括污泥还田利用、有机质回收、能量利用、制备建材等方面,并指出要综合考虑成本效益、市场需求、政策支持、环境效益等方面选择适应实际状况的最佳污泥处理处置方案,实现能源与资源的有效利用,促进经济循环发展,减少对环境的负面影响,实现可持续发展。
Sludge recycling not only reduces environmental pollution,but also realizes the reuse of resources and promotes sustainable economic development.It is an important measure for sewage treatment plants to practice the concept of green and circular development to deeply explore the efficient resource utilization path of sludge and con tinuously enhance the level of sludge resource utilization.According to the physical and chemical properties of sludge,this paper summarized various comprehensive utilization approaches for sludge from municipal wastewater treatment plants,including sludge fertilization,organic matter recovery,energy utilization,building materials production.The optimal sludge treatment and disposal strategy should be selected by comprehensively considering costeffectiveness,market demand,policy support,and environmental benefits.This approach could achieve efficient utilization of energy and resources,foster circular economic development,mitigate negative environmental impacts,and promote sustainable development.
