城镇污泥处理技术应用现状及发展趋势

摘要

With the rapid development of Chinese urbanization, the scale of water treatment and sludge increases largely, so sludge problem is imminent.To realize sludge reduction, stabilization, harmless and recycling is the goal of sludge disposal.The current application situation of domestic urban sludge treatment technology were overviewed and showed that sludge concentration, sludge dewatering, sludge digestion were widely used, the existing problems and future development trend were pointed out.It can provide a reference for sludge treatment scheme.%随着城市化进展的迅速发展，污水处理规模不断加大，随之产生的污泥量大幅增加。产生的大量城市污泥给环境带来巨大压力，污泥问题迫在眉睫。如何实现污泥减量化、稳定化、无害化、资源化，是污泥处理处置的目标。概述了目前国内城市广泛采用的污泥处理工艺技术即污泥浓缩、污泥脱水、污泥消化等工艺的应用现状，指出这些工艺存在的问题及未来发展趋势，为污泥处理方案的选择提供参考。
