| 摘 要： | 通过海藻酸钠固定化微生物小球对淡水养殖废水中活性磷、氨态氮、硝态氮、亚硝氮、化学需氧量质量浓度的影响,研究海藻酸钠固定化微生物处理淡水养殖废水的可行性。结果显示,海藻酸钠小球在养殖废水中极易溶解,不仅造成水体浑浊,且原生动物等可能以海藻酸钠为营养基而大量繁殖,进而导致水体缺氧,化学需氧量、氨氮等质量浓度不降反升,固定化微生物对废水的净化作用则难以显现。由此可见,以海藻酸钠为材料进行微生物固定化不适用于淡水养殖废水的净化处理。

| Abstract: | The treatment feasibility of aquaculture effluent with sodium alginate immobilized microorganisms was studied by monitoring the concentrations of ammonia nitrogen,nitrate nitrogen,nitrite,orthophosphate and COD.It was found that the pellets of sodium alginate were dissolved easily in freshwater aquaculture wastewater,and made the test water torridness,leading to oxygen deficiency,and high levels of ammonia nitrogen and COD derived from multiplication of protozoa.In other words,there was no decontamination t... |
