摘要
通过 4种催化剂对废水中有机物降解活性的比较 ,得出Ni2 O3/TiO2 催化活性最好 ,考察了用该催化剂光催化氧化处理蓖酸甲酯裂解废水时 ,催化剂用量、pH值、通气量、H2 O2 加入量与加入方式及紫外光照射时间对废水中有机物去除的最佳条件 .经该方法处理后 ,废水的CODCr去除率达 98.5% .
Making a compa ri son among organism degradation activities of the four catalyzers in waste water, Ni 2O 3/TiO 2 is the best, by investigation, when this catalyzer is used to process methyl splitting decomposition waste water by photocatalysis oxidation, the dosage of it, pH, the amount of air pumped, the additional amount of H 2O 2 and the time of ultraviolet light are optimum conditions for removing organism in waste water, after such a treatment, the removal percentage of COD Cr i s 98.5%.
