  • 摘要: 针对某工业园区混合类化工废水高色度、强酸性、高盐分和难降解且成分复杂的特点,采用以铁碳微电解技术对该混合类化工废水进行预处理。通过正交实验分析得出各因素对微电解出水处理效果的影响程度顺序分别为:铁炭形式>搅拌强度>反应时间。正交实验和单因素实验的结果表明,微电解实验水平中的最佳运行条件为:铁炭形式为铁炭混合填料、搅拌强度为350 r/min、反应时间为6 h、铁炭比为3:1、铁炭总投加量为192 g/L。在优化的运行条件下,出水的色度和COD的去除率分别达到36.0%和22.9%。同时,废水的可生化性也有很大提高,B/C提高了44.4%。
    Abstract: Fe/C micro-electrolysis was applied to pretreat the wastewater, which was sampled from the industrial park with high chroma, strong acid, high salinity, refractory and complex organic components. With the help of orthogonal test, the factors' impacts on micro-electrolysis effluent were listed as the following order: iron carbon form> stirring intensity > reaction time. The orthogonal test and single-factor test results showed that the optimum condition in the test was that the iron carbon was a kind of mixed packing, the stirring intensity was 350 r/min,the reaction time was 6 hours, the mass ratio of ferric to carbon was 3:1 and the iron-carbon dosage was 192 g/L. Under the optimal conditions, the removal rates of chroma and COD were 36.0% and 22.9%, respectively. Meanwhile, the biodegradability of wastewater was improved greatly with the B/C ratio increased by 44.4%.
