TGIC internal circulation anaerobic reactor

First, the process principle

TGIC anaerobic reactor height of up to 16m ~ 28m, higher than the average diameter of 4-8 from five basic components: a mixing zone, expanded granular sludge bed zone, refined handling area, and water area within the circulatory system. Wherein the circulation system is the core of the IC process, the lower three-phase separator, gas riser, the gas-liquid separator and the mud drops tubes. And UASB, significant differences EGSB reactor that "IC anaerobic reactor unique inner loop structure" biogas expansion work under the conditions of no external energy to achieve a circulation return within a large number of the mixture. Strengthen the mass transfer process, greatly improve the efficiency of removal of organic matter.

Second, the process

Wastewater first enters the bottom of the mixing zone of the reactor, and mixed well with the reflux liquid from the slurry drop tube, and then into the expanded granular sludge bed zone biochemical degradation of the region COD volume load is high, most of the COD is degraded here , the biogas produced is collected by the lower three-phase separator, gas bubbles are formed due to the process of expansion work done on the liquid produces a gas lift effect, so that the mixture gas, sludge and water along the riser gas rises to the top of the reactor gas-liquid separator, the gas here and the mud separation and export processing system. Water mixture is returned to the bottom along the drop tube reactor, and after the water mixed into the sludge bed expansion zone, a so-called inner loop. By effluent expanded granular sludge bed zone in addition to a portion of the processing involved in circulation, the remaining residual wastewater COD degradation and biogas production process by the underlying three-phase separator into the polishing zone, to enhance and ensure the water quality. As most of the COD has been degraded, so the lower COD load polishing zone, gas production is also smaller. Where biogas generated by the upper three-phase separator collected by the collecting pipe into the gas-liquid separator and export processing systems. Wastewater treatment after finishing top after the three-phase separator, the supernatant water is discharged outside the tank area.

Third, the process features

1, with high volumetric loading rate

Circulating water flow rate of up to 10 to 20 times the flow rate of the liquid rises more traditional reactor is increased from 8 to 20 times, and strengthen the organic and granular sludge mass transfer process.

Inner loop occurs only in expanded granular sludge bed zone, refined handling area gas load is low, creating a more stable precipitation conditions, granular sludge retention volume, high concentration.

Granular sludge bed zone bulking become fully fluidized state, small mass transfer constraints, much higher than the traditional active sludge reactor, the average sludge removal loading rate.

2, with a stable water effects

IC anaerobic reactor equipped with a sound monitoring system to ensure a uniform and stable water quantity, water quality. Reasonable internal structure design, shock load capability. A sophisticated debugging skills, hold a large amount of granular sludge.

3, shock load capability

Circulating water flow rate of up to 10 to 20 times, and the water circulating reflux next mixed reaction chamber, so that the original wastewater harmful substances are fully diluted and greatly reduce the harmful extent, improve the impact resistance of the reactor load capacity.

4, low operating costs

In appropriate alkalinity in presence of water, the PH value of the reactor water can be less, saving considerable costs cast base. Biogas upgrading generated a lot of internal circulation, reducing the need to improve the flow rate rises by the extra power consumption.

5, debug cycle is short

Under flow conditions with debugging (structures, equipment, piping, instrumentation, sludge inoculation, temperature conditions, etc.), a suitable amount of inoculum, the start-up period of two to four weeks.
