Study on Characters of More Spots Divisional Influent of Anaerobic Baffled Reactor Running
The anaerobic baffled reactor of four compartments adopted to the manner of divisional influent which was filled with stuffing and inoculated with the activated sludge of the secondary settlement tank for attached bio-film to train anaerobic microorganism. The divisional influent anaerobic baffled reactor (DIABR) was operated with influent ratio of 4∶3∶2∶1 in the four compartments and compared with the single influent anaerobic baffled reactor (SIABR). The examination studied on the way of start-up of DIABR and rernovaled effect of the contaminant under the different conditions of influent manner or hydraulic loading and organic loading. The result showed that the two reactors ran for 15 days under the conditions of HRT=8 h and ORL=0.8 kgCOD/m3.d, then the running parameter was modulated at a HRT of 4 h. At the 23 th day, the COD removal efficiency of the DIABR was higher than SIABR under the same conditions, the average removal rate of COD was 35％ when the reactors ran for 60 days, it can be deemed that the start-up on DIABR was successful. And the capability of treatment wastewater could be improved through properly changing the running manner of ABR for the different water quality and waterpower term.
