The residence time distribution in W-SFCW system experiments was studied using the reactor theory, from chemical engineering.
运用化学工程中反应器理论，试验分析波式潜流人工湿地（W-SFCW）中的停留时间分布。
DASB can remove the organic particle by its short-time anaerobic technology, thus preventing W-SFCW from jamming and affording enough carbon for denitrification.
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。
W-SFCW system, which provides more interaction surfaces for wastewater to react with soil, oval stone and small-sized stone layers, showed higher chances to form insoluble phosphate than SFCW.
SFCW由于使所有水流不断与土壤层、砾石层和豆石层反复接触，生成难溶性磷酸盐的几率大大高于SFCW，能够比SFCW更加显著地促进磷沉积。
