摘要:

为实现某尾矿库淋溶液达标回用,采用A/O与改进型 SBR联合工艺进行处理。结合生物脱氮理论与功能菌驯化工作,通过工艺调试与系统优化,解决了二沉池跑泥、污泥解体等问题,实现了淋溶液中总氰化物、COD和氨氮的高效去除。结果表明,处理后出水中COD、氨氮和总氰化合物可以稳定达到DB 21/1627—2008《污水综合排放标准》要求,为黄金冶炼行业尾矿库淋溶液的达标处理及回用提供了技术参考。

Abstract:

To achieve standard⁃compliant reuse of leachate from a tailings pond, a combined process of A/O andmodified SBR was adopted. Based on biological denitrification theory and acclimation of functional microorganisms,process commissioning and system optimization were carried out to address issues such as sludge washout and disinte⁃gration in Sedimentation Tank No.2. The combined system achieved efficient removal of total cyanide, COD, and ammonianitrogen from the leachate. Results show that the effluent concentrations of COD, ammonia nitrogen, and total cyanideconsistently met the requirements of DB 21/1627— 2008 Integrated Wastewater Discharge Standard. This studyprovides technical reference for the compliant treatment and reuse of leachate from tailings ponds in the gold smeltingindustry.
