DASB单元采用短时厌氧技术，去除颗粒有机物和部分溶解有机物，防止W -SFCW堵塞，保证W - SFCW单元脱氮所需的碳源。
DASB can remove the organic particle by its short-time anaerobic technology, thus preventing W-SFCW from jamming and affording enough carbon for denitrification.
当处理有机氨氮废水时固定化硝化污泥颗粒和固定化活性污泥颗粒均可实现一定程度的单级生物脱氮。
When used to treat wastewater composed NH4+-N and organic carbon source, the nitrifying activated sludge pellets and the activated sludge pellets can also produce SND phenomenon in a certain extent.
