摘　　要：我国城镇污水厂普遍存在进水C/N失调的现象,这是制约污水反硝化脱氮的重要因素。外加碳源强化反硝化过程是克服C/N失调的重要措施,但存在成本高、二次污染等问题。有机废弃物中含有丰富的碳源物质,有望替代污水厂使用的化石碳源,这有利于垃圾减量化及资源化,同时也能降低污水处理成本。对近年来国内外利用有机废弃物制备碳源的研究进展进行了归纳,主要是餐厨垃圾和果蔬垃圾;对碳源化过程的关键影响因素进行总结,概述了pH、温度、有机负荷、酶、不同预处理技术对碳源化过程的影响,以及有机废弃物碳源化利用技术在市政污水、垃圾渗滤液、养殖废水及污泥领域的应用现状,并展望有机废弃物碳源化利用技术的未来发展方向。The imbalance of influent C/N is common in urban sewage plants in China,which is an important factor restricting the denitrification of sewage.Adding extra carbon source to enhance denitrification process is an important measure to overcome C/N imbalance,but there were problems such as high cost and secondary pollution.Organic waste contained abundant carbon source substances,which were expected to replace fossil carbon sources used in sewage plants.It was conducive to the reduction and resource utilization of waste,while it could also reduce the cost of sewage treatment.The latest research in utilizing organic waste to produce carbon source both domestically and internationally was reviewed,mainly include food waste and fruit and vegetable waste.The key influencing factors of the carbon source process were summarize.The effects of pH,temperature,organic load,enzymes,and different pre-treatment technologies on the carbon source process were summarized.And the current application status of organic waste carbon source utilization technology in municipal wastewater,landfill leachate,aquaculture wastewater,and sludge fields were generalized,and look forward to the future development direction of organic waste carbon source utilization technology.
