摘要/Abstract

摘要：

本研究介绍了浙江省某垃圾焚烧厂渗滤液反硝化-硝化（Denitrification-Nitrification, DN）系统在高负荷冲击崩溃后，采用“带负荷调试”（Commissioning under load）策略实现快速恢复的工程案例。针对渗滤液处理系统因高氨氮负荷（氨氮浓度600~800 mg/L）冲击导致DN系统崩溃，且不具备外运处理条件的工况约束，本研究实施了渐进式带负荷调试方案，重点监测了水质指标（COD_Cr、NH₃-N、pH值）和环境参数（DO、温度）等关键因素。结果表明：在维持系统内氨氮浓度为600~800 mg/L的条件下，通过该策略，崩溃后的DN系统可在20~30 d内成功恢复功能，并逐步达到稳定运行状态（氨氮去除率>95%）。本研究为同类工况下受高氨氮冲击的生化系统快速恢复提供了可复用的技术参考。

Abstract:

This study presents an engineering case of rapid recovery using the “Commissioning under Load”strategy for a denitrification-nitrification (DN) system treating leachate at a waste incineration plant in Zhejiang Province, China， following system collapse due to high-load shock. Faced with the operational constraints of a DN system failure caused by high ammonia nitrogen load (NH?-N concentration: 600~800 mg/L) in the leachate treatment system and the lack of an off-site transportation option, this research implemented a progressive on-load debugging scheme. Key factors including water quality indicators (COD_Cr，NH₃-N，pH) and environmental parameters (dissolved oxygen - DO, temperature) were intensively monitored. The results demonstrate that under conditions maintaining the ammonia nitrogen concentration within the system at 600~800 mg/L, the collapsed DN system successfully regained functionality within 20~30 days using this strategy and progressively achieved stable operation (NH₃-N removal rate > 95%). This study provides a replicable technical reference for the rapid recovery of biological systems subjected to high ammonia nitrogen shock under similar operating conditions.
