铁碳微电解法预处理高浓度有机农药废水研究

摘要

本实验根据高浓度有机农药废水的特点，采用经过两次铁碳微电解，处理该类废水。实验表明，当pH=3.5，停留时间为1h。一次铁碳微电解后水COD去除率20.54%，二次铁碳微电解后去除率为35.31%。废水经处理后的可生化性得到提高。%In this study, according to the characteristics of the experimental water, the experimental treatment was carried out as follows:After two times micro-electrolysis, using biochemical breathing line method to measure the biodegradability change of the wastewater. Experiments showed that when pH=3.5, the residence time is 1 hour. After an iron-carbon microelectrolysis, the COD of wastewater could remove more than 20.54%, and post-secondary micro-electrolysis is 35.31%. The treated biodegradability of wastewater was also improved.
