摘要
近年来我国垃圾分类工作取得积极进展,垃圾分类可以有效改善人居生活环境,促进资源化利用。垃圾渗滤液是垃圾分类和处置过程中产生的二次污染,是一种高浓度有机废水。随着垃圾分类的积极推进,垃圾渗滤液的产生量将会减少,填埋场渗滤液C/N比失调的现象会更加严重,并且促使现有渗滤液处理工艺优化调整。垃圾分类会促使渗滤液处理领域排放标准发生变化,使其更加符合行业的特点和发展需求,并带动预脱氨、短程硝化反硝化和厌氧氨氧化等新的处理工艺在渗滤液处理领域广泛应用。从渗滤液产量、水质、处理工艺、排放标准、浓缩液和新工艺的推广应用等方面,阐述了垃圾分类对垃圾渗滤液处理领域的影响,以期为渗滤液处理行业健康发展提供借鉴和参考。
In recent years, China has made positive progress in waste classification. Waste classification can effectively improve the living environment of human settlements and promote the utilization of resources. Landfill leachate is a kind of high-concentration organic wastewater, which is the secondary pollution in the process of waste classification and disposal. With the active promotion of waste classification, the amount of landfill leachate will be reduced, the phenomenon of imbalance of landfill leachate C/N ratio will be more serious, and the existing leachate treatment process will be optimized and adjusted. Waste classification will change the emission standards in the field of leachate treatment, make it more in line with the characteristics and development needs of the industry. Novel treatment processes such as pre-deamination, short-cut nitrification and denitrification, and anaerobic ammonium oxidation are widely used in the field of leachate treatment. This article describes the impact of waste classification on waste leachate treatment from the aspects of the leachate production, water quality, treatment technique, emission standards, concentrates and the promotion of new technique, which will provide reference for the healthy development of leachate treatment industry.
