Abstract

The invention discloses a built-in block anaerobic reactor for organic wastewater, which belongs to the technical field of water treatment. It includes a reactor and a circulation pipeline. One end of the reactor is provided with a water inlet, and the other end is provided with a water outlet. In the reactor, a flocculent sludge area for filling flocculent sludge is arranged sequentially from the water inlet to the water outlet. The transition area for containing flocculent sludge and granular sludge and the granular sludge area for filling granular sludge; the granular sludge area and the transition area are equipped with a three-phase separation system; the reactor effluent passes through the circulation pipeline Return to the flocculent sludge area or the flocculent sludge area and the transition area; or, the effluent from the reactor flows back to the flocculent sludge area or the flocculent sludge area and the transition area through a circulation pipeline equipped with a metering pump.

Description

technical field

[0001] The invention belongs to water treatment technology, and more specifically relates to an anaerobic reactor device for fermenting high-concentration and large-volume organic waste water. Background technique

[0002] Anaerobic fermentation is a common treatment process for high-concentration organic wastewater. It converts organic matter in wastewater into methane through the action of anaerobic microorganisms. Methane can be burned to generate electricity and incorporated into the national grid. Therefore, the use of anaerobic reactors to treat high-concentration organic wastewater with good biochemical properties has irreplaceable advantages. While solving environmental problems, it has realized the resource utilization of high-concentration organic wastewater and achieved a win-win environment, economy and social benefits. .

[0003] The process of anaerobic fermentation of high-concentration organic wastewater to remove organic matter mainly includ...
