水解酸化+生物接触氧化法处理屠宰厂废水

Application of Hydrolysis Acidification and Contact Oxidation for Slaughterhouse Wastewater Treatment

采用水解酸化+生物接触氧化工艺处理山东省某屠宰厂废水,处理规模为4 500m^3/d。运行结果表明,系统出水水质均满足修改后的《南水北调沿线水污染物综合排放标准》(DB37/599—2006)的一级标准,具有处理效果好、运行稳定、抗冲击负荷能力强以及操作维护方便等优点,可为同类废水处理工程的设计和运行提供借鉴。

A combined process of hydrolysis acidification and contact oxidation unit was used to treat slaughterhouse wastewater. The treatment capacity was 4 500 m3/d. The operation results showed that the effluent quality could meet the modified I -class criteria in the Comprehensive Water Pollutants Discharge Standards along the South to North Water Diversion Project （ DB 37/599 - 2006 ）. The treat- ment process has advantages of good effluent quality, stable treatment performance, strong resistance to load impaetion, easy management and maintenance. The project could provide reference for design and operation of similar projects.
