The Research On The Utilization In The Treatment Of High Concentrated Sulfate Riboflavin Production Wastewater

The sources,characterstics and present treatment technology of high concentrated sulfate Riboflavin production wastewater were generalized in this paper.By the study of the wastewater characteratics,a sulfate reducing phase+methane producing phase + biodesulrization + CASS process had been detelminated.Meanwhile,the sludge inoculum,start-up,operation and control,efiece factors were investigated.In addition,the abnormal phenomena of operation and economic and technical indices of this project were analysed.The experimentaI restilts demonstrated that:(1)Sulfate redticing phase+methane producing phase+biodestilfurization+CASS process for treating high sulfate content wastewater was feasible,effective and economical,its effluent can meet the required effluent stalldards;(2)By means of controlling the effece factors in anaerobic process,it was feasible to reuse aerobic activated sludge to enforce anaerobic process;(3)Sulfate reducing phase+methane prodticing phase+biodesulfurization+CASS process to treat this wastewater was stabile and high efficient,and this process can generate energy.
