一种处理电镀废水的好氧颗粒污泥培养方法
摘要：
本发明涉及一种处理电镀废水的好氧颗粒污泥培养方法，属于废水处理技术领域。本发明以絮状污泥为接种污泥，将絮状污泥连续曝气24～30h后投加到SBR反应器中；以人工合成模拟污水作为进水，在SBR反应器中对接种污泥进行驯化培养和改性，所述驯化培养和改性包括第一阶段、第二阶段和第三阶段，第一阶段、第二阶段和第三阶段的进水中均包含有微量元素，所述微量元素包括MgSO4、CaCl2、MnCl2、CuSO4、ZnSO4、CoCl2、K2Cr2O4、NiCl2，驯化培养和改性结束，得到好氧颗粒污泥，本发明针对含有多种重金属离子，且COD指标不达标的电镀废水，制得的好氧颗粒污泥可一次性处理以上电镀废水，达到规定排放要求。
摘要（英）：

The invention relates to a method for culturing aerobic granular sludge for treating electroplating wastewater and belongs to the technical field of wastewater treatment. Flocculent sludge used as inoculated sludge is subjected to continuous aeration for 24-30 h and then added to an SBR reactor; artificially synthesized simulative sewage is used as inlet water, the inoculated sludge is subjected to acclimation culture and modification in the SBR, acclimation culture and modification comprise a first stage, a second stage and a third stage, inlet water at the first stage, the second stage and the third stage contains microelements including MgSO4, CaCl2, MnCl2, CuSO4, ZnSO4, CoCl2, K2Cr2O4 and NiCl2, and aerobic granular sludge is obtained after acclimation culture and modification end. The method is targeted at electroplating wastewater with multiple heavy metal ions and with the COD index not reaching the standard, the prepared aerobic granular sludge can treat the electroplating wastewater once, and the specified emission requirement can be met.
