摘要
采用吸附法,于室温下用活性炭脱除油田废水中的CODCr。结果表明,在吸附时间为30 min,废水pH值为5.9,活性炭用量为2 g的条件下,CODCr去除率大于50%。活性炭对CODCr的吸附过程为Freundlich等温吸附。
The removal of CODcr from oilfield wastewater was investigated at room temperature by using activated carbon. The results showed that the removal rate of CODcr was more than 50% under the conditions of adsorption time 30 min, pH value of wastewater 5.9, amount of activated carbon 2.0 g. The adsorption process of CODcr with activated carbon accorded with Freundlich model.
