Anaerobic reaction, it is by means of microorganism under anaerobic condition, the process to convert organic pollutant COD into biogas CH4, anaerobic reactor is applied to food, beverage, fermentation, papermaking, landfill leachate, etc. light industry extensively, wherein, IC anaerobic reactor has high treatment load, the floor area is small, the shock resistance is strong, run stably, the high advantage of reliability, mainly used for high concentration organic waste water treatment, SS content is higher or the waste water treatment that is toxic to microorganism, its principle is as follows:
the waste water is fed into the reactor via the water distributor and enters the first reaction area, i.e. the fluidized bed reaction chamber, where most of COD is degraded into marsh gas, the marsh gas generated in the reaction area is collected and separated by the first three-phase separator, and the generated gas enters the riser. The gas is lifted while driving the water and sludge to move upwards through the riser to the gas/liquid separator at the top of the reactor where the biogas is separated from the water and sludge leaving the entire reactor, the water and sludge being mixed and passing through a concentric downcomer to directly slide down to the bottom of the reactor to form an internal circulation flow. The effluent of the first stage reaction zone is deeply treated in the second stage deep purification reaction chamber, residual COD which can be anaerobically and biologically degraded is removed, the marsh gas generated in the upper separation zone is collected by the second three-phase separator at the top and is conveyed to the top spiral-flow type gas/liquid separator by the gas collecting pipe, and the marsh gas separation and collection are realized. Meanwhile, anaerobic effluent leaves the reactor through an effluent weir and automatically flows into the subsequent treatment.
However, the muddy water mixed liquid lifting pipe and the return pipe which are involved in the internal circulation process of the existing IC anaerobic reactor are easy to block, the internal circulation efficiency is affected by a light person, and the internal circulation is paralyzed seriously, so that the normal use of the reactor is affected.
