Abstract

Abstract:

Slaughtering wastewater is a type of high concentration organic wastewater with large amount and wide range. Based on the engineering experience and experimental research results of similar wastewater treatment, the main process of 'anaerobic reactor+Bardenpho+Fenton oxidation' was used to treat this wastewater. The actual operation results showed that this process had good treatment effect and stable operation, and the final effluent water quality met the first A discharge standard of the Pollutant Discharge Standard for Urban Sewage Treatment Plant(GB 18918-2002).

Key words: slaughter wastewater, anaerobic reactor, Bardenpho process

摘要：

屠宰废水是一种量大面广的高浓度有机废水，结合类似废水处理的工程经验和实验研究结果，本工程采用“厌氧反应器+Bardenpho+Fenton氧化”的主体工艺对此类废水进行处理。实际运行结果表明，该工艺处理效果好，运行稳定，最终出水水质能够达到《城镇污水处理厂污染物排放标准》（GB 18918—2002）中一级A规定的排放标准。
