摘要
针对制药废水有机物含量高、可生化性差的特点,利用铁碳微电解作为预处理方法,考察初始pH值、反应时间、铁碳质量比、铁屑投加量等因素对废水处理效果的影响,并考察了该技术对废水可生化性的影响,旨在为高浓度难降解制药废水的处理探索一条经济实用的新途径,并为其工业化应用做出铺垫。
In light of pharmaceutical wastewater features including high organisms content and bad biodegradability,applying ion-carbon internal electrolysis as the pretreatment method,the paper tests the impact of intimal pH value,reflection time,iron-carbon ratio and iron content upon wastewater treatment effect,and survey its impact upon the wastewater biodegradability,with a view to explore a new way of solving high concentration pharmaceutical wastewater treatment and lay a foundation of its chemical application.
