         The biodegradation of the IC reactor is divided into two stages. The first reaction zone at the bottom is at high load, and the second reaction zone at the top is at low load. The influent enters the first reaction zone from the bottom and is fully mixed with anaerobic activated sludge. Most of the organic matter is degraded into biogas in this zone, and the generated biogas is collected by the gas collection hood of the three-phase separator and rises along the biogas riser, At the same time as it rises, it also lifts the mixed liquid in the first reaction zone to the gas-liquid separator at the top.

       The biogas is discharged from the top, and the separated mud water mixture returns to the bottom of the first reaction zone along the mud water return pipe. It is fully mixed with the granular sludge and influent at the bottom, achieving internal circulation of the sludge. The result of internal circulation not only makes the first reaction zone have a high microbial biomass, a long sludge age, and a high upflow rate, It is generally 10-20m/h, allowing the granular sludge to fully reach a fluidized state, greatly improving the organic matter degradation rate
       The reaction process in the second reaction zone is basically the same as that in the first reaction zone, except that the flow rate is greatly reduced, usually 2-10m/h

        The main components of the UASB reactor include: inlet water distribution system, reaction zone, three-phase separator, outlet system, gas chamber, scum collection system, and sludge discharge system.
Advantages:
1. Double layer reaction bed, high volumetric load, high sludge concentration in the reactor, large microbial biomass, and internal circulation, good mass transfer effect, and influent load up to three times that of a regular reactor;
2. The reactor has a large aspect ratio (usually 4-8) and a small footprint;
3. Strong anti impact load capacity, a large amount of circulating water and influent water are fully mixed to fully dilute the harmful substances and concentration in the raw water, reducing the impact of harmful substances on anaerobic reactions;
4. Internal automatic circulation, without the need for external pump circulation, reduces energy consumption;
5. Short start-up cycle, high sludge activity in the reactor, and fast biological proliferationApplicable scope:
Suitable for high concentration organic wastewater, such as alcohol, molasses, citric acid and other wastewater;
Medium concentration wastewater, such as wastewater from beer, slaughtering, soft drinks, etc
Low concentration wastewater, such as domestic wastewater
