Description

Membrane filtration coupling single chamber swash plate multianode excess sludge microbial fuel cell unit
Technical field
The invention belongs to field of environment engineering technology, relate to excess sludge and process and technology of middle water recycle, particularly shouldSynchronously realize sludge reduction and energy recovery with single chamber swash plate multianode microbiological fuel cell, and complete the residue of membrane filtrationMud and sewage water treatment method.
Background technology
At present, exceed in the world 90% municipal sewage plant Bian activated sludge process or biomembrance process, processingIn process, produce a large amount of excess sludges. Existing sewage treatment plant lignin-sludge practices well is through concentrated, dehydration and stabilisationAfter be used further to fill out sea, burning or soil utilization etc. But sludge of sewage treatment plant amount is large, moisture content is high, complicated component and perishable,Sludge handling process energy consumption is high, have high input, and causes a large amount of undressed mud to be stacked arbitrarily or simple landfill, not only to environmentPollute, also waste the useful resources in mud. Excess sludge content of organics is high, is a kind of potential biomass energy,Can adopt anaerobic digestion process from mud, to extract biomass energy produces after biogas for generating. But digester need to be controlled temperatureScope is at 30-35 DEG C, and energy consumption is higher, and biogas changes into the higher energy loss of existence in electric energy process. So, at normal temperatureUnder condition of normal pressure, directly from mud, utilizing organic electrogenesis, will be a kind of more efficiently energy utilization patterns.
Excess sludge microbiological fuel cell (SMFC) can directly extract biomass energy from excess sludge, single chamber fortuneOK, without PEM, in producing electric energy, complete mud decrement. The anode of SMFC is immersed in conventionally at the bottom of reactorIn the mud of portion, negative electrode is placed in reactor top supernatant. Electrogenesis microorganism produces the organic matter in oxidatesElectronics is delivered to anode, and electronics arrives negative electrode by external circuit, with cathodic region dissolved oxygen be delivered to the matter of negative electrode from anode regionSon combination generates water, thereby organic pollutant removal and energy recovery are synchronously completed. If therefore excess sludge microorganism is firedMaterial battery is combined with sedimentation basin, can, under normal temperature and pressure conditions, reduce excess sludge production and produce electric energy.
The anode of SMFC is placed in bottom conventionally, but also has abundant biomass energy at the middle part of sedimentation basin. Sedimentation basin simultaneouslyMajor function be after sewage treatment plant's biological processing unit for Separation of Solid and Liquid, inclined-plate clarifying basin utilizes shallow pool theory passableImprove solid-liquid separation efficiency and usefulness. If utilize sedimentation basin bottom anaerobic environment, according to excess sludge microbiological fuel cellElectrogenesis principle is transformed sedimentation basin, and at sedimentation basin, swash plate anode is set according to shallow pool theory, can synchronously complete mudSeparation of Solid and Liquid, minimizing also utilize sedimentation basin bottom and the organic production capacity in middle part simultaneously, are expected significantly to reduce excess sludge placeReason complexity, reduces sewage treatment plant's floor space, investment and operating cost.
Second pond effluent quality cannot meet " urban wastewater treatment firm pollutant emission standard " (GB18918-conventionally2002) one-level A standard, municipal sewage plant need separately establish advanced treatment process. Membrane filtration technique can provide reliable good water outletWater quality, reduces product water efficiency but film pollutes meeting, increases operation complexity. At the excess sludge microorganism fuel by Modification of Secondary Settling TankCell cathode arranges membrane module and filters water outlet, will not only can improve effluent quality, can also utilize negative electrode to repel bear electroactiveMud, can effectively alleviate film and pollute, and membrane component and prolong service life, reduces maintenance cost.
Summary of the invention
The present invention seeks to design film separation coupling single chamber swash plate multianode microbiological fuel cell, synchronously complete sewage placeReason factory mud Separation of Solid and Liquid, minimizing production capacity improve effluent quality of sedimentation tank simultaneously. In the mud of sedimentation basin bottom, carbon is setFelt anode, utilizes organic electrogenesis in mud; Sedimentation basin middle part arranges swash plate anode, when improving deposition efficiency, in utilizationThe organic electrogenesis of clear liquid. At sedimentation basin liquid level, negative electrode is set, near negative electrode, settles membrane filtration module, improve sedimentation basin water outlet waterMatter, and the repulsive interaction for bear electropollution thing by negative electrode, and the barrier effect of swash plate, can stop part mudGrain floating, can alleviate film and pollute.
Swash plate multianode microbiological fuel cell is that the inclined-plate clarifying basin being designed by shallow pool theory carries out upgrading. TiltedlyPlate sedimentation basin can significantly improve deposition efficiency, and plate is apart from being the upward flow sloping plate sedimentation basin of 30-50mm, and its theoretical efficiency can reach advectionDoubly, because the current between swash plate are laminar condition, hydraulic radius is little, is more conducive to precipitate and separate for the 7-10 of sedimentation basin. ThisSwash plate anode in bright not only can increase deposition efficiency, can also increase annode area, utilizes sedimentation basin middle part to enrich organicMatter, improves electrogenesis usefulness and effectively stops mud floating, improves effluent quality. Swash plate anode utilizes plate face deposition produce simultaneouslyElectricity, also the synchronous swash plate surface deposition problem that solves, avoids stopping up and hindering current and proton transfer between swash plate.
Effluent quality of sedimentation tank cannot meet more and more stricter water standard. Membrane bioreactor is by membrane filtrationCan obtain reliable effluent quality, but membrane module is placed in activated sludge, film is seriously polluted, need frequently backwash orAeration washes away, and energy consumption is higher. In the application, membrane module is placed near negative electrode position, repels bear by the elecrtonegativity of negative electrodeElectroactive mud, can effectively alleviate film and pollute. The swash plate anode of installing in sedimentation basin can effectively stop mud granule simultaneouslyFloating, also can alleviate film and pollute, and is not therefore increasing under the condition of energy consumption, is expected to obtain reliable and stable effluent quality.
