摘要
本文研究了微电解工艺对某化工园区综合废水进行预处理的有机物去除效果。试验结果表明:铁碳微电解处理农药化工废水,可以大幅提高废水的可生化性,强化后续生物法处理废水的效果,使出水稳定达标。确定最佳工艺条件为:pH=3,微电解反应时间为2~3h,COD_(Cr)去除率达20%~30%。
The paper investigated the effectiveness of organics removal from the integrated wastewater of a certain chemical industrial park through pretreatment by the micro-electrolysis process.Experimental results indicated that treating pesticide chemical wastewater with the iron-carbon micro-electrolysis process can significantly enhance the biodegradability of the wastewater and strengthen the effects of the subsequent biological treatment,ensuring the effluent consistently meets the required standards.The optimal process conditions were determined as follows:pH=3,micro-electrolysis reaction time of 2~3 hours,the removal rate of COD_(Cr) reached 20%~30%.
