摘要/Abstract

摘要： 本研究以宁波某处理规模为1.0×105 m3/d的污水处理厂为依托，通过工程实践评估厨余垃圾湿式氧化产生的氧化液作为外加碳源的技术可行性与经济效益。试验分阶段将氧化液投加量从10 m3/d逐步提升至30 m3/d，替代部分乙酸钠投加至A/O系统反硝化池，考察其对系统处理效果及碳源成本的影响。结果表明，投加氧化液前后出水COD、TN始终稳定达标，未增加污染物排放风险。当氧化液投加量提升至30 m3/d时，系统COD去除率较未投加期提高约3.63个百分点；各投加阶段TN去除率较未投加氧化液时期均有提升。经济性分析显示，2024年实际运行期间投加氧化液节约的碳源成本为127.88元/m3。该研究为有机废弃物资源化与污水处理厂降本增效提供了切实可行的技术路径。

Abstract: ased on a sewage treatment plant in Ningbo with a processing capacity of 1.0×105 m3/d, this study evaluated the technical feasibility and economic benefits of using the oxidation liquid produced from the wet oxidation of kitchen waste as an additional carbon source through engineering practice. The experiment was conducted in stages, gradually increasing the dosage of the oxidation liquid from 10 m3/d to 30 m3/d, replacing part of the sodium acetate added to the denitrification tank of the A/O system, to investigate its impact on the system treatment effect and the carbon sources cost. Results showed that effluent COD and TN consistently met discharge standards before and after dosing oxidation liquid, with no increased risk of pollutant release. When the oxidation liquid dosage reached to 30 m3/d, the COD removal rate increased by approximately 3.63 percentage points compared to the period without oxidation liquid. TN removal also improved during all dosing phases. Economic analysis revealed that the cost of carbon source saved by adding oxidation liquid during the actual operation period in 2024 was 127.88 yuan per cubic meter. This study provided a practical technical pathway for the resource utilization of organic waste and the cost reduction and efficiency improvement of wastewater treatment plants.
