【摘要】 本试验从我国国情出发,立足于以空气作为氧源,以哈市城市污水为原污水,对两相及三相两种类型的生物流化床作了比较系统的试验研究,并与活性污泥法作了对比试验,对流化床的净化效果、效率与负荷的关系、温度的影响、载体的选择以及床内的脱膜方法等进行了比较广泛的探讨,取得了大量的数据,并作出了相应的结论。更多还原

【Abstract】 According to the conditions of our country, we used the air as oxygen source and municipal wastewater in Harbin as row waste water and made systematic experimental study of two kinds of biological fluidised beds: one with air—water mixed current, another with separate currents. We compared the results with those of activated sludge prosess and made a wide range of research into the relationship between the purifying efficiencies and the loads,the effect of temperature, the choice of carriers and the method of sloughing film and soon.A large number of data have bean abained, and relevant conclusions have been made.更多还原
