泡沫分离法在罗非鱼半咸水循环水系统中的水质净化效果
Water pur ification effect of foam fraction method in a bra cki sh rec irculating aquac ulture system
摘要
Abstract
With the rapid development of recirculating aquaculture system ( RAS ) technology, foam fractionation (also called air stripping) was used widely in sea water aquaculture water treatment , but in fresh water rarely, because of salinity.The changing of water quality for foam fractionation inlet and outlet was measured to study the water purification effect of mechanical air flotation foam fractionation methodology in a brackish RAS.The study results showed that , the combination of mechanical air flotation foam fractionation and dual-drain designing technology could undertake the main physical filtration task in a brackish RAS .The removal efficiencies of TSS, COD, TN, TP and color in mechanical air flotation could reach (37.19 ± 12.04)%, (21.89 ±6.19) %, (30.56 ±3.62)%, (19.38 ±5.27) % and (18.66 ±5.56)%, respectively.Integration of freshwater fish cultured in brackish water and foam fractionation technology is a practical and novel way to resolve the technical problem of removing micro suspended solids in fresh -water RAS.关键词
