粉末活性炭去除水中石油类污染物的试验研究

以0#柴油为研究对象,考察了粉末活性炭对水中石油类污染物的吸附性能.结果表明,采用粉末活性炭可有效去除水中的石油类污染物,当柴油初始质量浓度为3 mg/L,吸附时间为30 min,投炭量为20 mg/L时,纯水及原水条件下柴油的去除率均大于70％,且在最大投炭量(80 mg/L)条件下,粉末活性炭可以应对在纯水和原水条...

Removal of oil pollutants in water by powdered activated carbon

The adsorption property of oil pollutants in water by powdered activated carbon （PAC） were investigated using 0# diesel oil as study object. The results indicated that PAC could be used to remove oil pollutants in water. The removal effieiencies of pollutants in pure water and raw water could be all greater than 70% when the initial concentration of diesel oil was 3 rag/L, the adsorption time was 30 rain and dosage of PAC was 20 mg/L. PAC could be used for the treatment of diesel oil 29 and 30 times exceeding the standards in pure water and raw water with maximum PAC dosage of 80 mg/L.
