In practice, the main aquatic solids size ranges are less than 60μm in eel pond and larger than 300μm in abalone pond. The solid nitride concentration is two times over than soluble nitride in eel pond, but one third in abalone pond. 15cm inner diameter column,120μm bubble size, 15 to 18 liter per minute air flow rate and 7 to 10 liter per minute water flow rate were set, therefore the water retention time 138 sec in eel pond water and 197 sec in abalone pond water were controlled. The solid removal rate above 80% and the nitride removal rate 50% were get in eel pond, but the same removal rate could not get in abalone pond at the same process. The result that the water treatment design need follow within the different mass characteristics in any fish culture, and the adapt process design will be get in abalone pond in future.application/pdf35220 bytesapplication/pdfzh-TW國立臺灣大學生物環境系統工程學系暨研究所氣泡柱固形物總氮循環水養殖bubble columnsolidnitriderecir culated water culturereporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/10677/1/882313B002103.pdf
