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CODCr为100~650mg/L的条件下,出水CODCr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CODCr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。
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 CODcr is about 150-300 mg/L when the influent CODcr is 100-650 mg/L. Under the same condition, by using the HSB (high solution basteria) microbe, the effluent CODcr 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.
