Description
Technical field
The present invention relates to a kind of sewage disposal device and method, especially relate to the sewage that the solids content such as natural pond liquid is lower after sanitary sewage, organic sewage and solid-liquid separation.
Background technology
Pollutant component in sewage is complicated, is main greatly mainly with organic pollutant.Process for treating industrial waste water domestic at present mainly contains chemical method and biological treatment.Chemical method carries out the effect such as electrostatic neutralization, adsorption bridging by coagulating agent, inhibiter, Scale inhibitors, sterilant etc. to colloidal particle makes colloidal particle de-steady, in order to remove suspended substance in sewage and solubility organic pollutant.Depart from from water because organic pollutant is just condensed into bulk, organism itself is not effectively degraded, and causes a large amount of mud flco, make running cost high and produce secondary pollution; Biological treatment utilizes the biochemical action of microorganism, by the organic matter degradation of complexity, conversion, decontamination effect improving is higher than chemical method, avoid secondary pollution simultaneously, it is the most economical effective means of sewage disposal, and biological process is divided into the large class of activated sludge process and biomembrance process two, Activated Sludge Process is ripe, operational management is convenient, application is comparatively extensive, China have an appointment 40% municipal sewage plant adopt Activated Sludge Process.But greatly, easily there is sludge bulking, not high to sewage denitrification and dephosphorization processing efficiency in activated sludge process structures floor space.The immobilized microorganism technique being devoted to improve saprobia method processing efficiency in recent years obtains rapid progress, thus biomembrane process becomes the main flow direction of following biological sewage treatment development, representational bio membrane process has BAF, contact oxidation technology, blodisc and biological fluidized bed, wherein organism fluidization bed process is to solve BAF and contact oxidation technology pond body blockage problem and the New biological membrane method technique developed, it is by sand, gac, polymer carriers etc. are filled in reactor, at filling surface apposition growth microbial film, along with drainage flow or aeration make filler in reactor fluidisation, microbial film on filler contacts with dirty water pollutant and makes contaminant degradation.
Biochemical reactor at present for sewage disposal has anaerobic filter (AF), up-flow anaerobic sludge blanket (UASB), anaerobism floats film expanded bed reactor (AAFEB), anaerobic fluidized bed (AFB), anaerobe rotating disk (ARBCP), expanded granular sludge bed (EGSB), anaerobic internal circulation reactor (IC), anaerobic sequencing batch batch reactor (ASBR), anaerobic baffled reactor (ABR), upflowing segmentation sludge bed reactor (USSB), upflow sludge blanket-strainer reactor (UBF), anaerobic migrating blanket reactor (AMBR), anaerobic membrane bioreactor (AnMBR) etc.These reactors all also exist active sludge skewness in reactor, and need complicated triphase separator or the membrane module of costliness.Magnetic separation technique is a kind of technology of material being carried out magnetic field treatment, utilizes the difference of element or component magnetic susceptibility, by foreign field, material is carried out magnetic field treatment, thus reaches a kind of emerging technology of idetified separation process, belongs to physical partition method.Mainly utilizing magnetic----stress effect, applies magnetic field to waste water, makes the magnetic-particle in waste water magnetize, condense, and forms the flocs unit being easy to be separated, directly separates; For non-magnetic particle, carrying out chemical flocculation by adding magnetic kind, generating magnetic flocs unit thus being separated.Magneto separate water technology have investment little, treatment effect good, take up an area the advantages such as little.
Publication number be 102249404A patent discloses a kind of sewage disposal device containing magnetic carrier and sewage water treatment method, wherein said sewage disposal device comprises biochemical reaction tank, magnetic separator for separating of mud and magneticsubstance, device for dehydrating sladge waste and demoulding equipment.Independent magnetic separating apparatus is needed in this patent.
Publication number be 102070231A patent discloses a kind of combined type wastewater treatment method and device, wherein saidly in sewage, add magnetic kind, coagulating agent, coagulant aids carry out coagulating, now form magnetic flco group in water, by magnetic separation technique, magnetic flco group is separated from water again, now water body has purified up to standard, and isolated magnetic flco group is by the organic pollutant in electrochemical oxidation reactions brute force degraded flco group, its burning conversion is made to be water and carbonic acid gas, kill bacteria.Magnetic kind and nontoxic silt sediment are only contained after electrochemical treatment in magnetic flco group, then reclaim magnetic kind through calutron, continue recycle, and remaining nontoxic mud Direct Dehydration.Physico-chemical process is mainly adopted to carry out sewage disposal in this patent.
Publication number is 1204625 patent discloses a kind of microorganisms-immobilized magnetic carriers and produce the method for this magnetic carrier, and wherein relate in embodiment 9 and arrange dividing plate in reactor, magnetic carrier is adsorbed on permanent magnet, and they is maintained.Carrier in this embodiment is in be fixed but not flowable state.
Summary of the invention
The object of this patent there is active sludge skewness in current sewage-treating reactor, and need the problems such as the membrane module of complicated triphase separator or costliness, a kind of waste disposal plant based on magnetic carrier and method are provided, by making magnetic carrier at reactor internal circulation flow, magnetic carrier can be made fully to contact with sewage on the one hand, avoid follow-up magnetic kind to be in addition separated, be of value to the whole efficiency improving reactor.
For realizing above object, this invention takes following technical scheme: a kind of waste disposal plant containing magnetic carrier, the reactor of magnetic carrier is established in including, reactor is provided with water-in and water outlet, the dividing plate of at least one hollow is established in reactor, forming reactions district between dividing plate and between dividing plate and sidewall of reactor, the built-in magnetic coil that can be energized with the external world of dividing plate, described dividing plate is staggered, the formation water stream channel staggered between the bottom of described adjacent separator respectively and in reactor and top, by changing the order of magnetic coil energising, described magnetic carrier have in this water stream channel with effluent stream to consistent and with effluent stream to contrary state.
Described magnetic carrier is tool one or more materials magnetic.The adsorbable microorganism of described magnetic carrier.
A sewage water treatment method containing magnetic carrier, comprises the steps:
