Secondly, due to the long hydraulic retention time of the traditional anaerobic process, its equipment occupies a large area, which limits its popularization and application. With the continuous increase in the discharge of high-concentration organic wastewater in my country, the development of anaerobic biological wastewater treatment devices and methods with strong shock load resistance, small footprint, stable treatment performance, simple and easy-to-operate equipment and recyclable new energy has the advantages of important meaning.
