BioDopp工艺在乡镇污水处理厂的应用实例

An application example of BioDopp process in township sewage treatment plant

针对某乡镇污水可生化性一般,碳氮比低的特点,设计采用以水解酸化-BioDopp生化为主体的处理工艺,介绍了该工艺的处理流程、主要设计参数及处理效果。工程运行结果表明,该工艺脱氮除碳效果良好,处理出水能够稳定达到DB 51/2311—2016《四川省岷江、沱江流域水污染物排放标准》中工业集中区污水处理厂排放标准。

In view of the characteristics of township sewage such as general biodegradability,low carbon-nitrogen ratio and so on,a process with hydrolytic acidification-BioDopp biochemical method as the main technology was adopted in the design for its treatment.The flow,main design parameters and treatment effect of the said process were introduced.The project operation results showed that,the said process had good nitrogen and carbon removal performance,the effluent water quality could stably reach the discharge standard of industrial concentration area sewage treatment plant in DB 51/2311—2016 Discharge standard of water pollutants in Minjiang river and Toujiang river basin of Sichuan province.
