60%, the expansion rate of fluidized packing material is 100%, the fluidisation that described weak Micro Fluid packing area 4 and strong Micro Fluid packing area 2 are filled
Filler polyethylene is shaped as hollow cylindrical, and cross section is in protruding many pleats structure, and wherein pleat is triangle pleat, and filler external diameter is
1cm, a length of 1cm, bulk density is 0.14g/cm3, wet density is 0.90g/cm3；Described filter packing district 6 fills 100%
Fragment of brick, the outside of described anaerobic filter is additionally provided with water inlet system and circulation water gas system, and described water-locator 1 connects an intake pump
15, intake pump 15 connects a water sample bucket 17 and constitutes water inlet system；Described water-locator 1 is also connected with a water-circulating pump 16, and described water follows
Ring pump 16 connects outlet 10 and gas outlet 11 constitutes circulation water gas system, by controlling water-circulating pump quantity of circulating water size or natural pond
Gas circulating load size makes weak Micro Fluid packing area and produces by force the mutual pass of a kind of disturbance between Micro Fluid packing area and aqueous phase
System, will drive the internal generation in packing area Micro Fluid effect, and described strong Micro Fluid packing area 2 and weak Micro Fluid packing area 4 are filled
The expansion rate of polyethylene also controlled quantity of circulating water by water-circulating pump 16 and biogas recirculation amount realizes.
Above-mentioned anaerobic filter processes chemical engineering sewage PTA waste water CODCrConcentration be 5000mg/L, TA concentration be 2400mg/L,
PH is 4.5.Using this PTA waste water as processing object, table 3 below is result table
The table 3 multistage Micro Fluid collection depth-type filtration modified model anaerobic filter treatment effect to PTA waste water
| Testing index | CODCr(mg/l) | TA(mg/l) |
| Former water | 5000 | 2400 |
| Water outlet | 1000 | 500 |
By upper table 3 it can be seen that the anaerobic filter described in the present embodiment processes chemical engineering sewage PTA waste water CODCrPurifying rate is
80%, TA purifying rate is 79.2%.
Multistage Micro Fluid collection depth-type filtration described in above example 1～3 change type anaerobic filter utilize water-circulating pump to
Upper water distribution or upwards gas distribution, by regulating pondage or the size of biogas recirculation amount so that reach varying strength in different bed districts
Micro Fluid effect.This Micro Fluid effect can improve the internal channel, short of producing of anaerobic filter in tradition anaerobic filter running
The problems such as stream, dead band, improve the waterpower mass transfer effect within anaerobic filter.By the hydraulic disturbance of Micro Fluid, make sewage and stream
The biofilm contact changing filling surface is more abundant；The hydraulic shear effect that Micro Fluid produces simultaneously ensures that microorganism is constantly in
Higher biological activity state.And Micro Fluid bring waterpower flowing effect also can solve in anaerobic processes produce biogas
The problem that bubble is trapped between fluidized packing material, the bubble of upward flow is gradually increased along with current, participates in inner loop more
Increase the waterpower mass transfer effect within anaerobic filter
Sewage is through double-deck Micro Fluid packing area, and clean-up effect is wanted more preferably, and the stream as shown in Figure 2 filled
Changing filler polyethylene, polypropylene or the mixture of other modified class fluidized packing materials, outer surface protrudes many pleats and forms specific surface area greatly,
Bigger attachment space can be provided for the growth of microorganism, and described fluidized packing material has bioaffinity, bio-film colonization
Growth easily, the advantages such as after biofilm microbial activity is high.
Waste water through double-deck Micro Fluid packing area is the most purified, but may suspend anaerobic sludge, passes through
Filter packing district 6 retains anaerobic sludge, it is achieved water, mud and the three phase separation of bulky grain inert filler, it is not necessary to separately arrange
Three-phase diverter, it is ensured that the water outlet quality of anaerobic filter.And in described strong Micro Fluid packing area 2, weak Micro Fluid packing area 4,
Filter packing district 6 and exhalant region 9 are respectively provided with a sample tap, it is simple to monitoring in real time purifies water, and monitors clean-up effect.
In strong Micro Fluid packing area 2, weak Micro Fluid packing area 4, filter packing district 6 and exhalant region 9 be all provided with between any two
Put a homogeneous detachable dividing plate 8 of district's porous, the filter of each district can either be played and separate the effect from work, enable to again each layer
Filtering layer volumetric spaces is suitable, it is simple to form Micro Fluid pattern.
The outlet 10 of exhalant region 9 and the gas outlet 11 of collecting methane system are connected to outside described anaerobic filter 13
Water-circulating pump 16, constitutes circulation water gas system, it is achieved the self-loopa of resource, it is not necessary to additionally arrange water distribution system and gas distribution system
System, more environmentally-friendly, cost-effective.
Those of ordinary skill in the art it should be appreciated that above embodiment be intended merely to illustrate the present invention,
And be not used as limitation of the invention, the change as long as in the spirit of the present invention, to embodiment described above
Change, modification all will fall in scope of the presently claimed invention.
