In the anaerobic system of the utility model embodiment, in reactor 1, establish the packing layer 7 of porous, every layer of packing layer 7 is to cover the circular porous spherical particles thing of one deck at a skeleton, and porous spherical particles has huge surface-area, and porous surface provides growing carrier for anaerobe; Anaerobic bacteria flora has generated one deck anaerobe film at filler, namely at reactor 1 interior formation anaerobe bed, is made by porous material because of packing layer 7, and the anaerobe film of formation also has huge surface.The thickness of every layer of packing layer is (thickness of every layer of packing layer also can be decided according to organic pollutant content in the sewage) between 1~3m.
The protruded packing layer 7 of establishing in the reactor 1 of above-mentioned anaerobic system has following effect:
(1) packing layer 7 provides carrier for anaerobe group's growth, anaerobic bacteria flora generates one deck anaerobe film at packing layer 7, namely at reactor 1 interior formation anaerobe bed, made by porous material because of packing layer 7, the anaerobe film of formation also has huge surface.When sewage passes through, increased the chance that organic pollutants contacts with the anaerobe film, so that anaerobic reaction is more abundant, the clearance of organic pollutant is higher.
(2) anaerobe is attached on the packing layer 7 with biomembranous form, thereby has reduced the anaerobic sludge in the sewage.Anaerobic treatment of the prior art is not high because of the separation efficiency of mud, water, and the sludge stream vector is more.Reactor 1 has increased after the packing layer, and reactor 1 interior anaerobe reservation amount is improved.The mud that anaerobic treatment produces mainly is the mud that comes off from packing layer 7, these mud that come off from packing layer 7 are under action of gravitation, be deposited to reactor 1 bottom downwards, discharged by the device for discharging sludge 5 that is arranged on reactor 1 bottom, this just greatly improved mud in the reactor, moisture from efficient.
The device for discharging sludge 5 that the utility model arranges in reactor 1 bottom is conical hopper shape, and the unnecessary mud that produces like this is because gravity can be conveniently through 5 discharges of conical hopper shape device for discharging sludge.Device for discharging sludge 5 has following effect:
(1) moisture percentage in sewage sludge is low, and sludge volume can drop to minimum, because conical hopper bottom is less, and is not subjected to water currents away from whipping appts, institute's mud that produces is in " static " state in device for discharging sludge 5 bottoms, moisture percentage in sewage sludge reduction, sludge volume reduction;
(2) mud homogeneous is beneficial to follow-up sludge dewatering treatment, is in mud " static " state so that the Sludge Property stable homogeneous that precipitates;
(3) spoil disposal is thorough, avoids dirty stifled.Under the conical hopper state, mud emits successively, the situation that can not cause peripheral mud to discharge.The mud homogeneous, discharging is stable, causes dirty stifled probability extremely low.
The anaerobic system of the utility model embodiment can adopt the anaeration in normal temperature reaction, generally can adopt 27 ℃~37 ℃ anaeration in normal temperature reaction, the most reasonable from technology and economic aspect, the technical process that utilizes anaerobic system that the utility model embodiment provides that percolate is processed is as follows:
(1) sewage flow process: percolate is sent in the reactor 1 from the water-in 6 of reactor 1 bottom by sump pump, behind water distributor 4 water distribution uniformities, through packing layer 7 and whipping appts 2, rises to water outlet 8 and discharges, and enters next treatment process;
(2) mud flow process: the mud (mainly being the mud that comes off by on the packing layer 7) that reactor 1 interior anaerobic treatment produces is collected by the device for discharging sludge 5 that is located at reactor 1 bottom conical hopper shape, regularly discharges;
(3) biogas flow process: the gases such as biogas that reactor 1 interior anaerobe produces in digestion organic pollutant process, overflow from liquid level, discharge through the biogas drainage device 10 that is arranged on the conical head 9.
The above; it only is the better embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
