  • 摘要: 研究了对位酯生产废水的初步处理方案。先将对位酯废水进行中和、冷冻除盐、加CaO沉淀、过滤等预处理（预处理后COD 40.352 mg/L；SO2-4 9.577 mg/L; NH3-N 21 mg/L），再采用纳米光催化降解以及BaCl2进行处理，TiO2浓度为2 g/L时处理效果较好（COD 30.325 mg/L；SO2-4 880 mg/L ；NH3-N 140 mg/L）。废水经铁炭微电解及CaO处理后，再进行光催化降解可以达到更好的处理效果，COD降为 21.224 mg/L。废水经微电解、Fenton氧化和光催化联用处理后，COD降为20.800 mg/L。
    Abstract: Some initial treatment techniques for industrial wastewater from paraester production were investigated. Some pretreatment steps such as neutralization, desalination with freeze, precipitation by adding CaO, filtration were used to treat the paraester wastewater (after pretreatment COD 40.352 mg/L; SO2-4 9.577 mg/L; NH3-N 21 mg/L), then photocatalytic degradation and deposition with BaCl2 were used. When TiO2 concentration was 2 g/L, the better treatment results were observed (COD 30.325 mg/L; SO2-4 880 mg/L; NH3-N 140 mg/L). Alternatively, after the treatment of iron, charcoal, CaO and photocatalysis degradation process, the more effective results (COD 21.224 mg/L) were obtained. After the combined process of minute electrolysis, Fenton’s oxidation and photocatalysis degradation, the value of COD was further decreased to 20.800 mg/L.
