海绵铁预处理香料废水实验研究

Study of Pre-treatment of Perfume Wastewater by Using Sponge Iron

香料废水是一种高浓度、成分复杂、难生物降解的工业废水海绵铁是一种新兴的水处理材料。本实验利用海绵铁的吸附作用及电化学氧化还原作用,对香料废水进行预处理实验结果表明,海绵铁粒径选用0.9～1.6mm,投加量为15g,反应时间为60min,中性环境下,TOC去除率可达52%。

The characteristics of perfume wastewater are of complicated ingredients and of containing many high consistency and multi-ingredients organic pollutants. The experiments proved that the removal rate of TOC is 52% under the condition of the sponge iron of 15 g with a diameter ranging from 0.9 mm to1.6 mm and the reaction time of 60 min under a specific condition.
