苯酚 废水 混凝 双氧水 协同
针对苯酚废水难降解的问题，采用自制混凝剂协同双氧水对其进行处理。探究了混凝剂投加质量、双氧水用量、苯酚废水pH、混凝处理时间、双氧水氧化时间等因素对苯酚废水处理效果的影响。结果表明，室温、混凝剂投加质量为2.5 g、双氧水用量为1.6 mL、苯酚废水pH为4、混凝处理时间为30 min、双氧水氧化时间为25 min的实验条件下，质量浓度为50.0 mg/L、体积为1 L的苯酚废水经过处理后苯酚去除率可达96.8%。%To solve the problem that phenol-containing wastewater is difficult to degrade,a self-made coagulant combined with hydrogen peroxide is used to treat with phenol-containing wastewater.The influences of factors,such as coagulant dosage,hydrogen peroxide dosage,pH value of phenol-containing wastewater,coagulation treatment time,and hydrogen peroxide oxidation time on the treatment efficiency of phenol-containing wastewater are explored.It is shown by the results that phenol removal rate for 1 L of phenol wastewater with a concentration of 50.0 mg·L-1 can achieve 96.8％under the test conditions that at room temperature,coagulant dosage is 2.5 g,hydrogen peroxide dosage is 1.6 mL,wastewater pH value is 4,coagulation treatment time is 30 min,and hydrogen peroxide oxidation time is 25 min.
