Determination of discharge permit limits for indirect discharge enterprises with equivalent mass method: a case study in Changzhou City
-
摘要: 排污许可证制度是实施总量控制和减排任务的重要手段,是改善流域水环境质量的有效措施。间接排放企业是排污许可管理的重要对象,其排污许可限值是排污许可证发放的核心内容,我国关于间接排放企业排污许可限值的核定还没有统一的规定。通过借鉴美国国家污染物排放削减系统(NPDES)预处理机制,提出采用等效质量方法来确定间接排放企业排污许可限值,并以常州市某污水处理厂为研究对象,对该污水处理厂接纳的6家间接排放企业的污染物排污许可限值进行了研究。结果表明:采用等效质量方法计算出6家企业的等效质量负荷限值,结合我国现有排放标准浓度限值,可确定6家纳管企业CODCr的排污许可限值。等效质量方法在新建接管企业、现有企业停止接管和提高水质排放标准等多种情况下,能兼顾纳管企业的个体差异,方便灵活、便于应用。Abstract: The discharge permit system is an important means to control the total pollutant load and improve the watershed environmental quality. The indirect discharge enterprises (IDEs) are also included in the discharge permit system. It is a difficult problem on how to determine the discharge permit limit (DPL) for the IDEs, and there is no such a uniform regulation at the national level at present. By referring to the NPDES of the United States, the Equivalent Mass Method (EMM) was formulated to estimate the DPL for the IDEs. The EMM was successfully used to estimate the DPL for six IDEs, which were located in Changzhou City, Jiangsu Province and with the wastewater being discharged into one wastewater treatment plant. The EMM was used to calculate the equivalent mass load limits for the 6 enterprises and, in combination with the current discharge concentration standards, the CODCr DPLs were determined. Thus, the EMM is an effective method to estimate the discharge permit limits for the IDEs, and can be applied flexibly to the enterprises with different discharge characteristics, including newly built enterprises discharging into the pipeline network, existing enterprises stopping to discharge into the pipeline network, and under the circumstance of enhancing the discharge standards, etc.
