Problems solved by technology

The specific structure is composed of tower body, water distribution system, sludge bed, biological carrier area, three-phase separator, scum quick discharge device and reflux system, etc.; but it has the following defects: anaerobic microorganisms proliferate slowly, so anaerobic equipment starts And the treatment time is longer than that of aerobic equipment; the effluent often needs further treatment, so the aerobic treatment is generally connected in series after anaerobic treatment; the operation control factors of anaerobic treatment system are more complicated
Although it is a dynamic continuous fermentation method, the dynamic continuous fermentation method is an aerobic fermentation method
[0010] Traditional biogas digesters have no industrial value and can only be used in households, and the biogas produced can only be used as a supplementary energy source

Abstract

The invention relates to a multistage serially-connected biochemical reaction device and a flow type anaerobic fermentation method. The device at least comprises two reaction areas, a biological support is arranged in each reaction area, special microorganisms are adhered to the biological supports, an inlet and an outlet are respectively arranged at the lower portion and the upper portion of each reaction area, and the outlet of the front reaction area is connected with the inlet of the rear reaction area through a pipeline. The anaerobic fermentation method is that raw materials are pumped into at least two reaction areas in a sealed reaction device continuously and sequentially through a pump, and under the action of the special microorganisms adhered to the biological supports in the reaction areas, the raw materials achieve anaerobic fermentation and flow out of the last reaction area. The multistage serially-connected biochemical reaction device is used for treating human and animal excreta, crops such as straws, sewage sludge and other fermentable raw materials, solves the problems of environmental degradation caused by urbanization, large-scale breeding and the like and energy shortage, greatly improves the ecological environment, and facilitates sustainable development of the human society.
