摘要
随着我国近年城镇化进程加快,城市排水管网建设日趋完善,污水处理量逐渐加大,随之带来的污泥量与日俱增.结合国内外研究现状,对管渠污泥主要的几种处理手段进行对比,并从无机质和有机质资源化利用的角度出发,对管渠污泥的无害化和资源化处置进行深入剖析.现阶段的主要处理手段并不能完全解决市政管渠污泥无害化和资源化处置问题.基于当前的"双碳"战略和减污降碳规划,提出一种管渠污泥与园林绿化垃圾协同处置的好氧发酵堆肥生产绿化基质的闭环资源化治理思路.
Abstract
As the rapid development of urbanization in China in recent years,the construction of urban drainage networks is becoming increasingly perfect,and the amount of sewage treatment is gradually increasing,resulting in an increasing amount of sludge.Based on the current research status at home and abroad,this article compares the advantages and disadvantages of several main treatment methods for pipeline sludge,and analyzes the harmless and resourceful disposal of pipeline sludge from the perspective of resource utilization of inorganic and organic matter.At present,the main treatment methods cannot fully solve the problem of harmless and resourceful disposal of municipal canal sludge.Based on the current dual carbon strategy and pollution reduction and carbon reduction plan,a closed-loop resource management approach for the production of green substrates through aerobic fermentation composting for the collaborative disposal of pipeline sludge and landscaping waste is proposed.
