Equipment Description
IC anaerobic reactor represents the next generation of high-efficiency anaerobic treatment systems. This multi-stage design essentially functions like two stacked UASB reactors working in tandem. Its structure can be divided into five functional zones:
1. Mixed Zone: sewage, granular sludge and sludge-water mixture of reflux pairs are effectively mixed in this area.
2. The First Anaerobic Zone: under the action of high concentration of sludge, most of the organic matter is removed and converted into biogas, and part of the sludge-water mixture is lifted to the gas-liquid separation zone at the top of the reactor.
3. Gas-liquid Separation Zone: the biogas in the mixture is separated and exported, and the sludge-water mixture returns to the mixing zone to realize the internal circulation of the sludge mixture;
4. The Second Anaerobic Zone: The sewage in the first anaerobic zone enters the area through a three-phase separator, and further converts the remaining organic matter into biogas;
5. Precipitation Area: The mud-water mixture achieves solid-liquid separation in this area, and the supernatant is discharged.
- Widely used for high organic wastewater treatment;
- Organic loading can reach 30kg COD/m³.d;
- By-product methane, can be used as energy source;
- Less anaerobic sludge;
- High adjust ability;
- Less costs for equipment, running and maintenance;
- Good heat preservation performance, without heat;
- Preservation equipment, cost-saving.
1. Inlet wastewater flow into IC anaerobic reactor and mix with granular anaerobic biomass in water distributor;
2. Anaerobic biomass mainly works here, convert organic components into biogas(methane);
3. Biogas is collected in lower phase separator, generating a biogas lift;
4. Together with biogas, wastewater flows up in riser;
5. Biogas leaves the reactor in liquid/gas separator;
6. Water flowing down into distribution system, which is a whole internal circulation;
7. The outlet water is polished in second, upper compartment;
8. Biogas from the second compartment is collected in the upper phase separator;
9. Treated water exits the reactor
10. Biogas is collected.
IC anaerobic reactor is widely applied in places with foul odors (e.g. factories, garbage stations and sewage treatment plants).
