IC Anaerobic reactor for  high-concentration waste water treatment

IC brief

IC anaerobic reactors is a kind of high efficient circulation within the multistage reactor, is the third generation of anaerobic reactors, and the typical representative of the second generation of anaerobic reactors, it has compared the water even, the volume of high load (up to 15-30 kgCOD/m3 d.) operation is stable, impact resistant load ability, province, covering an area of less investment, etc. Has been successfully applied in the beer, paper, food processing industries of sewage treatment.

Features

1, the water evenly-IC anaerobic reactors because using zoning, multipoint, single feed line flow control, make the water more uniform.

2, the volume of high load-because of IC anaerobic reactors inner circulation in the role of the first anaerobic reaction chamber not only has high biomass, long sludge age, and there is a lot of liters flow speed, so that the indoor granular sludge fully meet the expansion. Fluidized state, have high mass transfer rate, make fully mixing mud, thus greatly improve the biochemical reaction rate and removal organic ability, volume load up to 15-30 kgCOD/m3 d., expansion area flow up at speeds of up to 10, 20 m/h.

3, impact resistant ability, good effect in the water
IC efficient anaerobic reactors is actually from bottom EGSB and the upper part of the reactor overlap a series UASB. Two of the reactor three-phase separator make biomass effectively stranded. Level 1 (bottom) separator separation and water, level 2 biogas separator (top) separation granular sludge and water, since most of methane gas has set up a file in the level of separation, the second get separator anaerobic reaction chamber almost nonexistent turbulence, therefore can not be secondary separator high gas velocity, the influence of can effectively separated the water granular sludge, and the water effect is good.
At the same time IC anaerobic process in the high volume of COD, under load gas ascension principle, utilize methane expansion without doing work in the conditions of the energy and realize circulation within the first reaction to return sludge, the actual water into water, is far greater than the water cycle of water into the 10, 20 times, circulating water dilute the water, improve the reactor impact resistant load ability and acid and alkali adjust ability.

4, capital construction investment province, covering an area of less-in the treatment of the same wastewater, IC anaerobic reactors load is the volume of ordinary 3, 4 times UASB, the only a third of the volume for a quarter-UASB, saving the infrastructure investment.
