摘要
经实验比较了UVO3、UVH2O2、UVTiO2H2O2系统对炼油高浓度废碱水的降解。结果表明,3种方法均有较好的效果,在本实验条件下,UVTiO2H2O2法的除油效果明显。在UVO3系统中,紫外光使废水CODCr、油、酚的降解率分别提高24%、31%、28%,特别是将废水BOD5CODCr值平均提高到0.45,有效地改善了废水的可生化性,因此是一种较好的预处理技术,同时该实验也为进一步的动态实验奠定基础。
It is compared that the degradation of refinery organic alkali wastewater with high concentration by UV/O_3,UV/H_2O_2 and UV/TiO_2/H_2O_2 systems.The results show that three methods all have good degradation effect.On condition of the experiment, UV/TiO_2/H_2O_2 process has an obvious effect of oil removal.In the UV/O_3 system ultraviolet light makes the degradation rates of COD_ Cr,oil and phenol in the watewater increase by 24%,31% and 28% respectively,and particularly let the average of BOD/COD_ Cr raise by 0.45.Thus the biodegradability of the wastewater is improved effectively.
