3.d, water inlet COD concentration 2000～30000mg/L, COD clearance 60～70%, height for reactor 10m.
Introduce the working process of CAFT efficient anaerobe reactor down below.
In the CAFT anaerobic biological reactor, anaerobion bacterium in water inlet and the reactor in the convective region 1 is in this district's thorough mixing and reaction, in the convective region 1, the anaerobion bacterium fully contacts with former water mixing, not only can allow the anaerobion bacterium be fit to such waste water, can obviously reduce the toxicity of former water simultaneously.Anaerobion bacterium and water inlet mixture move up with biogas simultaneously, arrive tube settler 5, oarse-grained mud 6 is separated from water, glides along the inclined tube wall, can fully contact mixing again with the current that rise, guarantee that water inlet can continue fully to contact mixing with anaerobion.
Through convective region 1, water quality is cleaned gradually, because fine active mud granule proportion is lighter in tube settler 5 water outlets, can't separate, therefore enter adsorption zone 2 with water, because the fine active mud granule in the water has stickiness and absorption property preferably, can be adsorbed in fully on the filler, this reactor adopts high-density packing, the active sludge that is adsorbed on the filler fully contacts with sewage, owing to intake after convective region 1 is handled, raw water quality is well improved, the growth and the propagation that help adsorption zone 2 active sludge guarantee that the water inlet pollutent obtains enough degradeds at adsorption zone 2.
After adsorption zone 2 is handled; entering organic matter of water is farthest degraded; adsorption zone 2 tops are provided with buffer zone 3; at buffer zone 3; the biogas that convective region 1 and adsorption zone 2 produce aggregates into big bubble, and the trickle active sludge generation throwing out that adsorption zone 2 comes off aggregates into the macrobead active sludge.Biogas, activated sludge particles and water enter triphase separator, and triphase separator adopts special construction, effectively solid-liquid gas are separated again, and biogas is by the sludge gas collecting device collection and treatment; The anaerobion bacterium that proportion is bigger is collected by settler and is back to convective region 1 by external circulating system 9, and the less anaerobion bacterium of proportion is then discharged reactor with water outlet.
This equipment external circulating system 9 mechanical powers adopt the anticorrosion pipeline impeller pump.External circulating system 9 has increased the upflow velocity of convective region 1, and the organism of convective region 1 and anaerobion bacterium contact area are increased, and has accelerated purification of water quality speed; Influent concentration has also been diluted in the water inlet that described external circulating system 9 provides, and has reduced organic acid concentration gradient in the reactor, has improved the living environment of anaerobion bacterium, has improved the degradation rate of anaerobion bacterium.
