| 摘 要： | 以江苏宜兴经济开发区为例,基于物质流分析构建了工业园区的氮代谢网络和分析方法,解析了工业园区中产业系统和污水处理系统的氮代谢途径和通量。研究表明,氮物质流系统的源和汇比磷物质流系统多,流通量大且较为集中;氮肥生产、纺织印染和食品加工行业是宜兴经济开发区的主要氮排放源;企业自备处理设施除氮效果较好,去除率约79%,而污水处理厂由于设计和运行等原因氮去除率较低,约57%;生活污水氮去除率低;直接排入水体的降水造成的水体负荷约28%。由此,建议企业继续完善企业内处理设施,对集中污水处理厂进行脱氮除磷提标改造,同时加强对园区内生活污水、生活垃圾和企业固体排放物的管理。

| Abstract: | Being hives of intensive industrial activities,industrial parks become the focus of water pollution control. However,water management at industrial levels is a challenging job because of the diversification of industrial types, complexity of wastewater treatment network,and interactive metabolism of various elements. Industrial metabolism, especially for phosphorus and nitrogen,can present insights for improving water use efficiency and reducing water pollution. Based on previous research of phosphorus meta... |
