摘　　要：本试验采用改良UASB反应器在常温条件下现场处理海藻酸钠废水,试验历时94 d,在絮状污泥为主条件下,容积负荷6.0 kgCOD/(m3.d)时,COD去除率达到85%,出水pH 6.8左右,VFA稳定在400 mg/L左右,设备运行稳定.试验结果表明,常温下利用改良UASB处理海带渣废水是可行的.Improved UASB reactor is applied to treat calcium alginate wastewater under normal temperature in the test. During 94 days, its volumetric loading rate is 6.0 kgCOD/（m3 · d）, COD removal rate is achieved above 85%, effluent pH is about 6.8, VFA is stable at 400 mg/L, and the system runs steadily in the case of flocculent sewage sludge. The results show that the application of improved UASB reactor to treating the highly-concentrated organic calcium alginate wastewater is feasible under normal temperature.
