摘 要: 主要采用活性炭吸附法和高锰酸钾预氧化法对某运河水的致嗅物去除工艺进行了研究。研究表明粉末活性炭最佳投加量是50 mg/L,此条件活性炭吸附平衡时间为30 min;高锰酸钾最佳投加量为3 mg/L,这样有助于保持运河水体的平衡,避免对微生物产生影响;两种方法均能有效地去除水中的嗅味,使嗅阀值由42降至23以下,明显改善了水的嗅味问题。 To eliminate the odor in a canal of one city in China, a study is performed on the typical odorant by oxidation and removal process. Results show that oxidation and adsorption can effectively eliminate the odor. The best dosage of carbon is 50 mg/ L, and after 30 rain the adsorption reaches the equilibrium. Potassium oxidation is also used, and the best dostage is 3 mg/L, which would be better to the microscopic organisms and keep the balance in the canal. After dealing with the two methods, odor threshold can decrease from 42 to 23.
