Abstract

The invention discloses a combination type anaerobic digestion reactor. The combination type anaerobic digestion reactor comprises a return-flow tank, a reaction tank, a water inlet pipe and a return-flow pipe, the bottom part of the return-flow tank is communicated with the bottom part of the reaction tank through the water inlet pipe, a sludge discharge area, a jet type water distributor, a granule sludge bed, a biological packing area, a three-phase separator and a water outlet are sequentially arranged in a tank body of the reaction tank from bottom to top, one end of the return-flow pipeis communicated with the water outlet, the other end of the return-flow pipe is communicated with the top part of the return-flow tank, and a water inlet is formed in the bottom part of the return-flow pipe. The inner main structure of the traditional UBF (Upflow Blanket Filter) reactor is improved and optimized, the three-phase separator, a return-flow system comprising the return-flow pipe and the return-flow tank, an online pH control device and the jet type water distributor are added, and the combination type anaerobic digestion reactor improves the SS sewage treatment capability, the pollutant load impact resistance and the stability of the traditional anaerobic digestion reactor, and has the characteristics of simpleness in operation, safety, reliability, and high treatment efficiency.

Description

technical field [0001] The invention relates to the field of industrial wastewater treatment, in particular to a composite anaerobic digestion reactor. Background technique [0002] The upflow anaerobic sludge bed-filter anaerobic digestion reactor (UBF) developed by Canadian scholar S.R.Guiot in 1984 combines the advantages of UASB and AF. For example, the upper packing layer of UBF replaces the three upper parts of UASB. Separator, the structure of the whole reactor is simpler; the upper and lower parts of UBF can maintain a high biomass concentration, which increases the total biomass of the whole reactor, thereby improving the processing capacity and the ability to resist shock load. However, due to the cancellation of the three-phase separator in UBF, the concentration of SS in the effluent increases, which affects the quality of the effluent. Hebei Institute of Light and Chemical Industry has developed a UBF reactor with a three-phase separator: fiber-filled upflow an...
