水解酸化+两级AO/MBR+臭氧催化氧化+BAF+气浮处理TFT-LCD废水
Gongye shui chuli以某薄膜晶体管液晶显示器（TFT-LCD）企业的废水处理厂为例，对其接纳的废水进行分析。针对废水成分复杂、水质变化大、污染物浓度高、可生化性差以及排放要求高的特点，将废水分为有机废水、酸碱废水和含氟废水进行分类收集、分质预处理，经预处理后的3种废水混合后再进行进一步处理。根据混合废水的水质特性，设计开发了水解酸化+两级AO/MBR+臭氧催化氧化+BAF（DN型）+气浮+次氯酸钠消毒的组合处理工艺。运行结果表明，该组合工艺运行稳定，试运行期间平均出水COD、BOD5、NH3-N、TP、TN、SS、F ...
