摘要
实施最严格水资源管理制度"三条红线"的管理目标中,水功能区限制纳污是其中之一。限制纳污需要确定水域纳污能力,而现行的《水域纳污能力计算规程(GB/T 25173—2010)》在实际应用中存在较大争议。从设计水文条件的设置、污染源、排污口概化、计算模型与反应参数等方面对当前的纳污能力计算方法进行了详细的分析,指出了目前的处理方式产生争议的原因及相应的解决对策,并结合美国环保局的TMDL思想内涵,探讨TMDL对我国纳污能力计算的借鉴意义,最后提出了开展以水生态系统健康为目标的动态、多指针、综合点源与面源污染生态纳污能力的计算思路。
Restriction of pollution discharge in water function zones is one of the three measures listed in the stringent water resources management system of ＂three redlines＂. In order to define the pollutant carrying capacity of water bodies, the calculation code （GB/T 25173 2010） is adopted in practice but be disputed. A detailed analysis is conducted from five aspects： setting of designed hydrological condition, pollution sources, drainage generalization, index selection and the calculation model with reaction parameters. Potential problems are pointed out when using current method and corresponding provided. The connotation of TMDL by United State EPA is expounded for reference in China. Finally, a carrying capacity aiming at conservation of aquatic ecosystem is suggested by taking dynamic modeling, complex model structure, point source and non-point pollution into full consideration.
