有机高分子絮凝剂处理炼油废水的初步研究

用有机高分子絮凝剂聚丙烯酰胺(PAM)与壳聚糖分别处理炼油废水,考察了pH、温度、絮凝剂投加量、沉降时间等因素对絮凝效果的影响。结果表明,壳聚糖的处理效果优于PAM;PAM处理炼油废水的最佳条件为:用量3 mg/L,pH为8,温度30℃,沉降时间40 min,此时石油类物质的去除率达97.96%,COD去除率达90.92%,NH3—N去除率达54.36%;壳聚糖处理炼油废水的最佳条件为:用量100 mg/L,pH为8,温度35℃,沉降时间40 min,此时石油类物质的去除率达98.33%,COD去除率达92.25%,NH3—N去除率达52.60%。

Study on the treatment of refinery wastewater by organic polymer flocculant

The paper has discussed two kinds of organic high polymer flocculant polyacrylamide(PAM) and the shell polyose to refinery wastewater processing.Discussed pH,temperature,flocculant dosage,deposit time on flocculation.We discovered that the shell polyose processing effect is superior to the PAM.The optimum condition of PAM processing refinery wastewater are:amount 3 mg/L,pH 8,temperature 30 ℃,settling time 40 min,then the elimination rate of petroleum class reaches 97.96%,COD elimination rate reach 90.92%,NH3—N elimination rate reach 54.36%.The optimum condition of shell polyose processing refinery wastewater is:amount 100 mg/L,pH 8,temperature 35 ℃,settling time 40 min,then the petroleum class elimination rate reaches 98.33%,COD elimination rate reach 92.25%,NH3—N elimination rate reach 52.60%.
