Embodiment
As shown in Figure 1, full mixing mass transfer anaerobic reactor of the present utility model, mainly comprise pond body 1 and knockout drum 10, knockout drum 10 is arranged on the top of pond body 1, knockout drum 10 is provided with water inlet pipe 12.Pond body 1 adopts steel construction, whole structures are column, upper end is uncovered, bottom gas skirt 3 and upper-part centralized gas hood is provided with in it, the periphery of upper-part centralized gas hood is provided with gutter spout funnel 14, the periphery of bottom gas skirt 3 also can arrange gutter spout funnel, and gutter spout funnel 14 is fixed on pond body 1 inwall, and the up-flow being provided with muddy water between gas skirt current stitches.
The top of upper-part centralized gas hood is provided with sedimentation and filtration district 7, is provided with the filtering layer of polyurethanes in sedimentation and filtration district 7, and the top in sedimentation and filtration district 7 is provided with effluent weir 9, and effluent weir 9 is provided with rising pipe 8.Be provided with stripping tube 5 and Duo Gen downcomer 4 in pond body 1, stripping tube 5 is through each gas skirt 3, and its upper end is stretched in knockout drum 10, and lower end is stretched in the gas skirt 3 of bottom, and the position of stripping tube 5 in upper-part centralized gas hood is provided with extract mouth 6.The upper end of every root downcomer 4 is connected with the bottom of knockout drum 10, and communicates with knockout drum inside, and lower end extend into the top of bottom gas skirt 3.Stripping tube 5 and downcomer 4 are connected and fixed with upper and lower two gas skirts.
The bottom of pond body 1 is provided with shore pipe 2, can be provided with control valve on shore pipe 2, forms sludge drainage system, opens control valve, discharged by self-pressure during spoil disposal.
The operational process of above-mentioned reactor is as described below:
Waste water directly enters in knockout drum 10 by water inlet pipe 13, is dropped down onto the bottom of pond body 1 by each downcomer 4.The biogas produced in pond body 1 makes waste water density reduce, obvious density difference is formed with the external world, so gas-liquid is in the lower port in the gas skirt 3 of bottom by stripping tube 5 and the extract mouth 6 that is in upper-part centralized gas hood upwards promotes along stripping tube 5 under the effect of ambient pressure, enter in knockout drum 10, air release in knockout drum 10 is also discharged by venting port 11.Muddy water mixed solution falls back along downcomer 4 under gravity together with the waste water entered by water inlet pipe 13 bottom of pond body 1, in pond body 1, there is anerobe to organic degraded, produce biogas simultaneously, again form gas-solid-liquid, and be promoted to knockout drum 10 by stripping tube 5, form circulation.
It is external that clear liquid discharges pond through filtrating area, settling region 7 and effluent weir 9 along rising pipe 8, and mud to sedimentation at the bottom of pond, is regularly discharged outside pond through shore pipe 2 under gravity.
In gas-liquid air lift process, gas-liquid rises, make to form negative pressure in gas skirt, (upwards being run by the gap between gas skirt and pond body 1) is supplemented fast from bottom to top by the muddy water mixed solution refluxed bottom the body of pond, gas-liquid cycle is fast, the organic waste water of high density fully contacts with microorganism at short notice, Fast-propagation for particulate matter provides sufficient nutrient material, promote biological self reproducing, simultaneously by high speed shear with wash away, substantially increase mixing efficiency and mass-transfer efficiency, quick formation aerobic particle mud, microorganism and the abundant absorption degradation of organic pollutant, participate in the removal of pollutent.Gas skirt participates in gas-solid-liquid and is separated, and granule sludge retains through the stop of gas skirt, eliminates triphase separator.
The more important thing is, water inlet anaerobic reactor in top of the present utility model adopts top water inlet, entered by knockout drum 10, enter from top to bottom together with air lift to the muddy water mixed solution in knockout drum 10 bottom the body of pond, also mass transfer is participated in, waste water is participated in the overall process mass transfer, and mass transfer is more violent, substantially increases mass-transfer efficiency.Meanwhile, eliminate the water distributor of bottom water intake mode, thoroughly prevent water distributing pore blockage problem, reactor is run continuously.
