Study on treatment of polytetrahydrofuran wastewater by iron-carbon micro electrolysis

摘要

The wastewater produced from the polytetrahydrofuran (PolyTHF) was treated with iron-carbon micro electrolysis process. This paper had studied the COD removal efficiency influences of primary PH value, reaction time, the quality ratio of the iron-carbon, the quality and volume ratio of Fe-wastewater. The results show that when pH value is 3, the quality ratio of the iron-carbon is 1:1 and the quality and volume ratio of Fe and wastewater is 1:7 with contact time of 90 min, the wastewater COD removal rate can reach as high as 95.0%.
