| 摘 要： | 针对鱼粉加工废水经过混凝处理后仍含有较高浓度的COD（50g／L以上）、氨氮（4g/L以上）、盐分（5g/L以上）的问题，从有机负荷、进水和出水pH、挥发性脂肪酸、氨氮、盐分等方面，研究了常温下UASB的启动特性及其处理效果。结果表明，UASB反应器对鱼粉加工废水具有较好的处理效果，反应器内能形成大量的颗粒污泥，启动迅速、运行稳定，具有较强的酸、碱缓冲能力，未出现氨氮和脂肪酸的积累和抑制微生物活性的现象。当进水COD为15～20．5g／L、容积负荷为8～9kg／（m^3·d）时，出水COD为2500mg／L（对COD的去除率〉85％），产气量为0．46L/gCOD（CH4含量〉80％，具有较高的利用价值）。颗粒污泥呈黑色椭圆状，粒径主要分布在0．315—3mm，污泥浓度为35g／L，MLVSS／MLSS为0．908，颗粒污泥的沉速为52．5～138m／h（沉降性能良好）。

| Abstract: | The wastewater from fishmeal processing factories contains high levels of COD (>50 g/L),NH3-N (>4 g/L) and salinity (>5 g/L) even after coagulation. The performance of treatment by the UASB reactor under normal temperature was investigated,and the impacts of organic load,pH,VFA,NH3-N and salinity were analyzed. The results show that the UASB reactor is capable of removing pollutants from the wastewater. The large amounts of granular sludge are formed in the reactor,the stable operation and strong buffering ... |
