The role of clogging in intermittent sand filter (ISF) performance in treating rural wastewater retention pond effluent

Popis výsledku v původním jazyce

Although biofilm growth caused clogging is often considered detrimental to the performance of intermittent sand filters (ISF), the presence of biofilm in ISF is indispensable for wastewater treatment. In this study, the role of biofilm growth clogging in ISF performance is studied by pilot experiments and biokinetic simulation. Both the pilot experiments and the simulation demonstrate that biofilm growth is significantly enhanced in the top layers of ISF and is dominantly comprised of heterotrophs. The clogging development zone was responsible for the majority of organic carbon and NH4+-N removal. Simultaneous nitrification and denitrification (SND) also occurred in the clogging development zone. The development of clogging can also enhance the organic carbon and NH4+-N removals as well as SND. Monte Carlo analysis indicated the lifetime of an ISF is negatively related to influent strength and hydraulic loading rate (HLR), and is more sensitive to influent strength than HLR. Although biofilm clogging
