However, the traditional anaerobic sewage treatment process generally has the problems of long starting time and loss of anaerobic sludge along with reaction, so that the treatment efficiency is low, the effluent effect is poor, and the recycling requirement is difficult to meet. At present, most of rural sewage treatment processes are anaerobic and aerobic processes, so that heavy treatment, light utilization and low resource utilization degree are realized.
At present, the traditional high-efficiency anaerobic process realizes the interception and enrichment of anaerobic microorganisms mainly by methods of forming anaerobic granular sludge or forming a biological film on the surface of a carrier and the like. The traditional anaerobic folded plate reactor has the problems of long starting time, difficult two-phase separation, unstable treatment effect and the like when treating rural sewage; when the anaerobic biofilter is used for treating rural sewage, the filler is easy to block, the treatment efficiency is low, and the anaerobic biofilter is not suitable for treating high organic load sewage.
