摘要
采用硫酸亚铁与高锰酸钾联合氧化深度处理酵母废水,分别研究了在曝气条件下硫酸亚铁投加量、pH值、反应时间对COD去除率的影响,以及联合高锰酸钾情况下高锰酸钾投加量、pH值、反应时间对COD去除率的影响。结果表明,在曝气条件下,硫酸亚铁投加量为5.0 g.L-1、pH值为7.0、反应时间为50 min时,COD去除率可达60%~65%;在联合高锰酸钾条件下,高锰酸钾投加量为1.0 g.L-1、pH值为8.0、反应时间为10 min时,COD去除率可达75%左右。处理废水达到排放标准。
The advanced treatment of yeast wastewater was carried out by combined oxidation of ferrous sulphate and potassium permanganate.The effects of influential factors on the COD removal rate were studied.Results showed that the COD removal rate reached 60%~65% with 5.0 g·L-1 of ferrous sulphate,7.0 of pH value,50 min of reaction time under aeration condition,and the COD removal rate reached 75% or so with 1.0 g·L-1 of potassium permanganate,8.0 of pH value,10 min of reaction time.The treated wastewater met the requirement of discharge standard.
