| Abstract: | Under the condition of normal teraperature, the experiment makes a study of the sludge gas circulating UASB reactor treatment efficiency for urban sanitary sewage of low concentration and influence of sludge gas circulating way. The experiment indicates that, under the condition of normal temperature, the reactor can operate stably and the liquid is clear. The CODcr volume load is 5.0 kg/（m3 · d）. The rate of removal CODcr is above 80%. Mean-while, researches also show that the sludge gas circulating time has an important effect on stable operation of UASB reactor. |
