Embodiment Construction
[0016] Multi-power internal circulation flow anaerobic reactor, including the internal circulation system composed of the first reaction zone 2 and the second reaction zone 3, as well as the water distribution system 5 and the entire internal circulation system throughout the first reaction zone 3 and the second reaction zone 3 The downpipe 4 is connected with the water inlet pipe 1 of the water distribution system and the downpipe 4 of the internal circulation system by means of a combination device, and the power of the raw water is used to strengthen the return flow of the mud-water mixture in the downpipe to ensure the normal operation of the internal circulation system.
[0017] The device connects the water inlet pipe and the downpipe, and uses the abundant energy in the reactor water as another driving force for the internal circulation of the IC reactor to ensure the normal operation of the internal circulation system. By strengthening the internal circulation process, ...

The invention relates to a multi-power internal circulation flow anaerobic reactor, including an internal circulation system composed of a first reaction zone and a second reaction zone, a water distribution system and the entire internal circulation system running through the first reaction zone and the second reaction zone The downpipe is characterized in that: the inlet pipe of the water distribution system and the downpipe of the internal circulation system are connected by a connecting device, and the power of the raw water is used to strengthen the return of the mud-water mixture in the downpipe to ensure the normal operation of the internal circulation system . The beneficial effect of the present invention is that: the invention of the multi-power internal circulation flow anaerobic reactor changes the source of circulation power of the traditional internal circulation flow reactor and adds a new member to the large family of anaerobic reactors. Even when the gas production in the first reaction zone is low and the internal circulation power is insufficient, the multi-power internal circulation anaerobic reactor can still work normally.
Description
technical field [0001] The invention belongs to the field of sewage treatment, in particular to a multi-power internal circulation flow anaerobic reactor. Background technique [0002] The internal circulation anaerobic reactor (IC) is a high-efficiency anaerobic reactor developed by the Netherlands PAQUE company in the mid-1980s. According to statistics, the market share of this type of reactor has reached 34%. From a macroscopic point of view, the IC reactor is a fully mixed anaerobic reactor (the first reaction zone) and an anaerobic reactor (the second reaction zone) working in a plug-flow state working in series along the longitudinal direction. Composite reactor. From the perspective of application, this reactor has the following advantages: (1) High volume load and small footprint. The sludge concentration in the IC reactor is high, the microbial biomass is large, and the internal circulation makes the mass transfer effect very good. The influent organic load can ...
