有色园区工业污水处理厂铊提标改造工程实例

The Example of Thallium Upgrading and Reconstruction Project of Industrial Sewage Treatment Plant in Nonferrous Metals Industrial Park

以某有色工业园区集中式工业污水处理厂为例,为解决园区初期雨水收集和铊排放标准提标存在的问题,进行园区初期雨水收集池建设,并对原有除铊工艺系统进行针对性改造,经过近三个月运行效果证明,初期雨水得到有效收集,铊排放浓度稳定低于《工业废水铊污染物排放标准》(DB 43/968-2021)总铊排放浓度限值。

Taking a centralized industrial sewage treatment plant in a nonferrous Industrial Park as an example,in order to solve the problems existing in the initial rainwater collection and the stricter discharge standard of thallium in the park,the initial rainwater collection tank in the park was constructed,and the original thallium removal process system was modified.The operation effect for nearly three months has proved that the initial rainwater is effectively collected.The thallium emission concentration is steadily lower than the limit of total thallium emission concentration in the《discharge standard of thallium pollutants in industrial wastewater》(DB 43/968-2021).
