中美水污染物排污许可限值核定技术对比

随着中国大力推广排污许可证制度在全国范围内的实施，排污许可限值作为排污许可证中的关键点，其重要性日益凸显。论文重点从排污许可限值核定技术的法律规范基础、基于技术和基于水质的核定技术3个方面，对比研究中美两国排污许可限值核定实践与科研现状。通过对比美国排污许可限值核定技术的特点与经验，分析总结出我国排污许可限值核定技术存在的法律法规不完善、技术指导文件不详细、基于技术的限值核定技术精确度低和基于水质的限值核定技术缺乏等问题，最终为我国排污许可限值核定技术在上述几个方面的完善提供建议。

A COMPARATIVE STUDY ON ASSESSMENT TECHNOLOGY OF POLLUTANTS DISCHARGE PERMIT LIMITS BETWEEN CHINA AND THE UNITED STATES

As China vigorously promotes the implementation of pollutant discharge permit system nationwide, emission permit limits become increasingly important as the key point of pollutant discharge permit.This paper focused on the comparison of the practice and research status of the pollution permit limit approval technology in China and the United States from three aspects:verification methods based on legal basis, technologies and water quality. Comparing the characteristics and experiences between the US and China technology for the verification of emission permit limits, this paper summarized the problems existing in China's corresponding technologies. Such as the imperfect laws and regulations, the incomplete technical guidance documents, low accuracy of technology-based technology for the verification of emission permit limits, and lack of technology for the verification of emission permit limits based on water quality. Finally, it provided suggestions for the improvement of emission permit limit verification technology in China.
