摘要: 以某煤炭机械加工厂的含乳化液废水为研究对象，采用混凝沉淀破乳-芬顿氧化-紫外光照射相组合的工艺进行废水处理，考察3个分工艺主要因素对废水中污染物去除效果的影响.结果表明：在混凝沉淀破乳实验中分别加入质量分数为0.5%的PAC和质量分数为0.05%的PAM时，对含乳化液废水的破乳效果较好；适宜的芬顿氧化反应条件为芬顿试剂的配比n（H₂O₂）：n（FeSO₄）=8：1，0.815 mol/L的FeSO₄投加量8 mL，质量分数为30%的H₂O₂投加量7.41 mL，废水初始pH值2~3；紫外光照射与芬顿试剂协同作用时，能有效提高含乳化液废水中污染物的去除率，反应进行0.5 h即可使废水中COD和NH₄⁺-N的质量浓度分别降低至2.67×10^-4 g/L和1.30×10^-5 g/L，满足企业排放要求.

Abstract: Taking the emulsion wastewater in a coal machinery processing plant as the research object, the coagulation sedimentation demulsification-Fenton oxidation-ultraviolet light irradiation combined process was used to treat the emulsion wastewater, and the effects of the main factors of the three process on the removal of pollutants were investigated.The results showed that the demulsification effect of emulsion wastewater was better when PAC with a mass fraction of 0.5% and PAM with a mass fraction of 0.05% were added in the coagulation sedimentation demulsification experiment; the more suitable Fenton oxidation reaction condition were Fenton reagent ratio n(H₂O₂):n(FeSO₄)=8:1, 0.815 mol/L FeSO₄ dosing amount 8 mL, 30% H₂O₂ dosing amount 7.41 mL, initial pH of wastewater was 2~3; When ultraviolet light irradiation worked in synergy with Fenton's reagent, it could effectively improve the removal rate of pollutants in emulsion wastewater.If the reaction was carried out for 0.5 h, the mass concentration of COD and NH₄⁺-N in the wastewater could be reduced to 2.67×10^-4 g/L and 1.30×10^-5 g/L, respectively, meeting the emission requirements of enterprises.
