| 摘 要： | 采用转鼓铁碳微电解法预处理液晶生产废水，优化了工艺参数，并进行了装置连续运行试验。结果表明：保持转鼓转速2 r/min，在废水pH=2.0、铁碳比（m（铸铁屑）∶m（活性炭））1∶1.5、填料装填率（填料体积与反应器有效容积之比）1∶10、HRT=3 h的优化工艺条件下，废水BOD5/COD由处理前的0.181提高到0.265；电解装置连续运行30 d，COD去除率稳定在40.1%~43.2%之间，且填料未出现板结现象。

| Abstract: | Liquid crystal wastewater was pretreated by rotary drum iron-carbon microelectrolysis process. The process parameters were optimized,and the continuous running test was carried out. Under the optimum process conditions of drum rotation rate 2 r/min,wastewater pH 2.0,m(cast-iron scrap)∶m(activated carbon)=1∶1.5,packing loading ratio (ratio of packing volume to reactor effective volume) 1∶10 and HRT=3 h,BOD5/COD of the wastewater is increased from 0.181 to 0.265. During 30 d of continuous running,the COD removal rate is 40.1%-43.2%,and there is no phenomenon of hardening and agglutination in the packing layer. |
