摘要

斑節蝦（Penaeus japonicus Bate）養殖水常需以1:1之海水:地下水混成含鹽度1.5~2.0%，以增加其生長與繁殖力。密集養殖之結果，其所產生之廢水中常含高濃度之COD，氮與磷，除造成環境惡化外，還引出病毒Monodon baculovivus (MBV)之感染問題。本研究成功地應用A_2O生物反應器馴化而發展出一協同微生態系統(Synergistic microecosystem)，其去除COD、氮、磷之能力極佳，去除率各別可達55.0%，88.9%，以及100%，證明此一微生態系統極適用於海水或半海水養殖廢水之處理

The shrimp aqua culture pond water normally requires a salinity of 1.5~2.0% in order to retain survival and fertility of the shrimps, the excretions in such dense shrimp culture may contain much of Nand P-contaminations, which could cause severe environmental deterioration and terrible pathogenecity, Monodon baculovivus (MBV). We investigated that the N- and P- removals were accomplished successfully by using an A_2O bioreactor that consisted of several species of chloride-tolerant microorganisms in a well balanced synergistic microecosystem interacting synergistically. The overall COD, N- and P-eliminations reached 55.0%, 88.9%, and 100%, respectively. Results imply that this chloride-tolerant micro-ecosystem (CTM) is pertinently feasible for treatment of seawater- or high chloride containing aqua culture wastewaters.
