    摘要
  • 摘要: 近年来,城镇排水管网的安全运维备受关注,通沟污泥的合理处置已成为重要挑战。为了满足2022 年发布的《城镇排水系统通沟污泥处理处置技术规程》要求,通沟污泥的有机组分须降至5%以下,才能进行安全填埋或回用。其关键在于通沟污泥有机和无机组分有效分离,然而目前相关研究相对不足。综述了通沟污泥的组分特性及其对环境的影响,重点探讨了传统水力淘洗、典型水解方法以及新型离子交换技术在通沟污泥处理中的应用现状,但已有研究仍较为有限。通过对比分析不同处理方法对有机/无机组分分离的效能和机制,评估其优缺点,包括工程实施难度、环境影响和经济效益。结果表明:基于树脂的离子交换处理因其高效分离效果和可持续性,成为未来通沟污泥处理的前沿方向。研究结果为进一步完善通沟污泥有机/无机组分分离理论提供了理论支持和实践指导,促进了新型通沟污泥处理技术的发展与应用。
    Abstract: The safe operation and maintenance of urban drainage networks, especially the proper disposal of sewer sediment, has become an urgent challenge as urbanization accelerates and wastewater treatment processes generate increasing amounts of sediment. In response, the Technical Regulations for the Treatment and Disposal of Sewer Sludge in Urban Drainage Systems, released in 2022, mandates that the organic component of sewer sediment must be reduced to 5% below, before it can be safely landfilled or reused as building materials. This requirement depends on the effective separation of organic and inorganic sewer sediment components, a complex process that has not been deeply studied. Traditional treatment methods, such as multi-stage hydraulic panning, rely on hydraulic forces and material concentration differences to separate the components. However, the methods are inefficient and consume numerous water resources. In contrast, newer technologies, alkaline hydrolysis, thermal hydrolysis, and CER (cation exchange resin), offer promising solutions to improve the separation efficiency. These methods aim to break down biopolymers directly or disrupt ion bridges through CER, thereby promoting the decomposition of sediment. Direct cracking methods focus on the breaking of biopolymers. While indirect approaches, CER, focus on breaking down the bonds that hold the components together. Although the number of research on CER treatment remains limited, it offers a more sustainable solution than traditional methods. This review explored the composition and environmental hazards of sewer sediment, emphasizing the importance of effective separation of organic and inorganic components. The current status of traditional hydraulic panning, typical hydrolysis methods, and CER technology were studied. By comparing the efficiency and mechanisms of those methods, the review evaluated the advantages and disadvantages from the perspective of engineering implementation, environmental impact, and economic benefits. The findings suggested that CER treatment, with high separation efficiency and sustainability, holds great potential in future sewer sediment management. Overall, this review provides both theoretical insights and practical guidance for advancing the understanding of organic/inorganic component separation in sewer sediment and encourages the development of efficient treatment technologies. A new recycling method of CER is also proposed to increase the economic and environmental benefits of sediment treatment.
