膨胀石墨污水净化处理研究
Research on Sewage Water Purification by Expansion Graphite
【摘要】 利用膨胀石墨强大的吸附能力来处理城市生活污水,结果发现用膨胀石墨处理污水的前8h,COD的去除率达43%;处理第5~9d将出现第二个高峰,COD的去除率达48%。分析原因可能是存在物理吸附和微生物絮凝两方面的作用。最后经过20d的处理,膨胀石墨对生活污水的COD和BOD总去除率分别达到86%、78.9%,且除臭能力也很显著。
【Abstract】 Expansion graphite was applied to treat sewage water because of its powerful adsorption.As a result,COD reduced 43% in the first 8h treatment with expansion graphite;then from the 5th day to 9th day,the second peak came,the removal of COD reached 48%.It may be affected by both physical adsorption and flocculation of microbe.After 20d’s treatment with expansion graphite,the BOD and COD of sewage sample had reduced 86.7% and 78.9% respectively.The ability of excluding odour is also notable.
