摘要：

采用Fenton 试剂对实验室模拟高浓度叔丁醇废水进行预处理，探讨了H₂O₂投加量、Fe²⁺投加量、pH 及反应时间等因素对废水COD 去除率的影响。结果表明，在H₂O₂投加量为25 mL，Fe²⁺投加量为0.75 g，pH 为3~5，反应时间为30 min，反应温度为30~35 ℃的条件下处理200 mL 模拟废水，COD 去除率可达90%以上。

Abstract:

Fenton reagent has been used for the pretreatment of laboratorial simulated wastewater containing highly concentrated tetrabutyl alcohol（TBA）. The effects of the factors，such as H₂O₂ dosage，Fe²⁺ dosage，pH and reaction time，etc.，on wastewater COD removing rate are discussed. The results show that when 200 mL of wastewater is treated under the following conditions： H₂O₂ dosage is 25 mL，Fe²⁺dosage 0.75 g，pH=3－5，reaction time 30 min，and reaction temperature 30－35 ℃，the COD removing rate reaches 90%.
