- 摘要:
- 针对某松香加工厂废水水质成分复杂,含有大量的乳化松香、树脂酸、动植物油、单宁等污染物,色度高,可生化性差等特点,采用隔油+混凝气浮+Fenton氧化预处理工艺去除废水中大量的乳化松香、动植物油类污染物,并降低色度,提高废水可生化性,再通过UASB+生物接触氧化处理工艺降解废水中的有机污染物。工程调试运行结果显示,该组合工艺对COD、BOD5、动植物油、悬浮物、色度的平均去除率分别达到98.8%、98.6%、99.1%、97.0%、99.3%,最终出水COD≤100 mg/L、BOD5 ≤20 mg/L、动植物油≤10 mg/L、悬浮物≤70 mg/L、色度≤50倍,满足《污水综合排放标准》(GB 8978—1996)的一级标准。
- Abstract:
- In view of the complex composition and characteristics of high color and poor biodegradability of wastewater from a rosin processing plant, which contains a lot of pollutants such as emulsified rosin, resin acids, animal and vegetable oils, tannins, the pretreatment process including oil separation, coagulation flotation, and Fenton oxidation is adopted to remove a large amount of emulsified rosin, animal and vegetable oil pollutants in wastewater, and reduce chromaticity, improve wastewater biodegradability, and then the combined process of UASB and biological contact oxidation are used to degrade organic pollutants in wastewater. The results of engineering commissioning operation show that the average COD, BOD5, animal and vegetable oil, suspended solids, and chromaticity, removal rates of the combined process are 98.8%, 98.6%, 99.1%, 97.0%, and 99.3% respectively. The final effluent COD, BOD5, animal and vegetable oil, suspended solids, chromaticity are no more than 100 mg/L, 20 mg/L, 10 mg/L, 70 mg/L, and 50 times, meeting the first-level criteria of Integrated Wastewater Discharge Standard (GB 8978-1996).
