EVALUATION ON A PILOT-SCALE ATTACHED-GROWTH POND SYSTEM TREATING DOMESTIC WASTE-WATER

Pilot-scale experiments on attached-growth ponds (AGP) had been conduc ted to investigate the feasibility of improving waste stabilization po nds (WSP) performance through the incorporation of attached-growth med ia (AGM) or the so-called artificial fibrous carriers in the pond wate r. Better removal efficiencies of COD, BOD5 and NH4-N had been obtaine d in the AGP than in the conventional WSP through the comparative stud ies. On the basis of these results, a pilot-scale AGP system had been built and run, which had shown to have great advantages and stabilitie s with better effluent quality in performance in comparison with conve ntional WSP.
