The Key Impact Factors of the Integrative Biological Reactor(IBR) Treating Urban Wastewater and Cheap Waste and Producing Energy Simultaneously
Urban wastewater and cheap waste had become a troublesome problem in the field of wastewater treatment.In this paper,a novel integrated biological reactor (IBR) was operated for the simultaneous treatment of municipal wastewater,molasses wastewater and cheap wastes,as well as the production of methane.In order to shorten the start-up period,the molasses was firstly used to start the IBR,and the substrate was gradually replaced by corn straw hydrolysate,which is difficult to decompose.The experiment results showed that the start-up period was greatly shortened to only 19 days.While utilizing corn straw hydrolyzate at the higher volume load rate of 10.4 kg-COD/m3-d,the COD concentration of 28800 mg/L.and the HRT of 11.08 h,the IBR reached the highest COD removal rate of 84.2% with the biogas production rate of 1.21 L/L - d.The alkalinity was proportional to the biogas production,and the ORP performed a decrease trend to the increased biogas production.Finally,it can be concluded that the IBR presented a higher stability and large amount of methane production even under higher organic load.The novel IBR system was proved to be a low-cost,stable and convenient way for biogas production from special wastewater and cheap wastes.
