Abstract:

The experimental result and defect of Fenton technique for treating H₂O₂ wastewater are analysed. It is pointed out that pH and residual H₂O₂ are the most important factors which have influence on the Fenton technique treatment. The following biological treatment experiment indicates that the general biological contact Oxidation effluent COD_Cr is about 150-300 mg/L when the influent COD_Cr is 100-650 mg/L. Under the same condition, by using the HSB ( high solution basteria) microbe, the effluent COD_Cr is less than 150 mg/L. It meets the requirements of the Second Grade of Wastewater Discharging Standard (GB 8978-1996). The study proves that the Fenton technique + HSB microbe is an efficient method for treating H₂O₂ wastewater.

摘要：

分析了Fenton工艺处理过氧化氢生产废水的缺点，经过对实验结果的分析，指出pH和残余H₂O₂是影响Fenton工艺处理效果的重要因素。后一步的生物处理实验结果表明：普通的生物接触氧化法处理物化出水，在进水COD_Cr为100～650mg/L的条件下，出水COD_Cr为150～300mg/L。在相同的进水和实验条件下，采用HSB(highsolutionbacteria)微生物，出水COD_Cr小于150mg/L，达到GB8978-1996二级排放标准。通过实验证明了Fenton+HSB微生物法是处理过氧化氢生产废水行之有效的方法。
