摘要
对合成橡胶废水提出了水解酸化与生物接触氧化相结合的处理工艺。试验研究表明,该工艺对COD和BOD5的平均去除率分别为87.5%和90%。在进水COD和BOD5分别平均为656mg/L和286mg/L的情况下,出水COD和BOD5分别平均为82mg/L和28.6mg/L,达到国家排放标准。水解酸化可将合成橡胶废水的BOD5/COD由0.44提高至0.56。
A study on the treatment of synthetic rubber wastewater by hydrolytic acidification biological contact oxidation process is presented in this paper. Experiment results show that COD can be reduced from 656 mg/L to 82 mg/L and BOD 5 from 286 mg/L to 28.6 mg/L by the process, with 87.5% and 90% of average removal rate respectively, which can meet the national discharge standards. The biodegradability (BOD 5/COD) of synthetic rubber wastewater can be raised from 0.44 to 0.56 via hydrolytic acidification treatment.
