基于先进技术的印染行业企业许可排放量核定方法研究:以太湖流域为例

针对太湖流域水环境质量改善的特殊要求,聚焦太湖流域印染行业,构建了涵盖生产工艺与设备、资源能源利用、污染物产生、经济效益、工艺设备、处理效果以及管理水平等指标的企业先进性评价指标体系,并将印染产品由GB 4287-2012《纺织染整工业水污染物排放标准》中的5大类细化为14类。结果表明:采用企业监测数据、行业标准、环统数据以及排污许可申报数据4种方式计算取严得到的单位产品污染物排放负荷限值,远低于GB 4287-2012的排放限值,并在此基础上形成了完整的技术方案,可为基于先进技术的排污许可限值的确定提供依据,并为排污许可证制度的实施提供技术参考。

VERIFICATION METHOD OF THE PERMITTED EMISSIONS OF PRINTING AND DYEING ENTERPRISES BASED ON ADVANCED TECHNOLOGIES: A CASE STUDY OF THE TAIHU LAKE BASIN

In response to the special requirements for water environment quality improvement in the Taihu Lake Basin, this article focused on the printing and dyeing industry in the Taihu Lake Basin, and built an enterprise advanced in production technology and equipment, resource and energy utilization, pollutant generation, economic benefits, process equipment, treatment effects, and management level. The evaluation index system for performance, and printing and dyeing products were refined into 4 categories from 5 categories in the Water Pollutant Discharge Standard for Textile Dyeing and Finishing Industry (GB 4287-2012). The study found that the pollutants discharge load limit per unit product calculated and strictly obtained using four methods including enterprise monitoring data, industry standards, environmental statistics and pollutant discharge permit declaration data was far lower than the current national emission limit. On this basis, a complete technical plan was formed, which could provide a basis for the determination of pollution permit limits for this industry and other industries based on advanced technologies, and provide technical support for the implementation of the pollution permit system.
