中文摘要:
      摘要:对植物油精炼污水处理工艺进行新增预处理工艺改造。实践表明:相比原工艺,新增静置分离隔油、三级斜板隔油、硫酸亚铁絮凝后气浮、芬顿氧化预处理工艺后,精炼污水CODCr平均下降78.41%,含磷量平均下降78.57%,污泥量平均降低了65.04%,排放出水水质100%达到国家一级排放标准,同时副产品皂脚量增长36.84%,增加了经济效益。该工艺过程操作简单,可适用于植物油精炼污水的净化处理。
英文摘要:
      Abstract:The treatment technology of wastewater from vegetable oil refining was improved by adding pretreatment process. The practice showed that compared with the original process, adding static settlement to separate oil, three-stage inclined plate oil separation, air flotation after ferrous sulfate flocculation and Fenton oxidation pretreatment processes could reduce the CODCr and phosphate content in discharge wastewater by 78.41% and 78.57% on average respectively, reduce the sludge content by 65.04% on average, and the discharge water quality reached the national first-level standard. In addition, the amount of byproduct soap increased by 36.84%, which increasing the economic benefits. The new process was easy to operate and was suitable for the treatment of vegetable oil refining wastewater.
