A kind of high-concentration organic wastewater treatment system
Technical field
The present invention relates to a kind of water treatment system, and in particular to a kind of high-concentration organic wastewater treatment system.
Background technology
At present, the organic wastewater treatment process such as sanitary sewage is mainly formed by precipitating and being aerated twice technique(It is corresponding useless Water treatment system includes sedimentation basin and aeration tank), this technique and system are organic in high concentration of the processing with certain solid holdup Waste water(The life organic wastewater concentrated such as pasture, the waste water of feed lot or personnel)When because sludge yield is big, organic loading is high So that wastewater treatment is extremely difficult, processing cost is very high;And waste water processing station odor pollution especially severe.
The content of the invention
A kind of high-concentration organic wastewater treatment system is provided the invention aims to overcome the deficiencies in the prior art.
To reach above-mentioned purpose, the technical solution adopted in the present invention is:A kind of high-concentration organic wastewater treatment system, it It is mixed including adjusting adsorption tank, the solid-liquid separating machine being connected with the regulation adsorption tank, being connected with the solid-liquid separating machine Solidifying precipitation reactor, the fixed interval (FI) filter being connected with the coagulating sedimentation reactor and the fixed interval (FI) filter The facultative aerobic membrane bioreactor that is connected, the UASB reactors being connected with the facultative aerobic membrane bioreactor, with the UASB Contact oxidation reactor that reactor is connected, the more medium filter being connected with the contact oxidation reactor, with it is described Anti-pollution reverse-osmosis machine that more medium filter is connected, respectively with the facultative aerobic membrane bioreactor and the UASB reactors The sludge homogeneous pond that is connected and respectively with the coagulating sedimentation reactor, the facultative aerobic membrane bioreactor and described contacting Oxidation reactor is connected for the blower fan divulged information to it.
Optimally, the regulation adsorption tank is also connected with the sludge homogeneous pond and the more medium filter respectively.
Because above-mentioned technical proposal is used, the present invention has following advantages compared with prior art:High concentration of the present invention has Machine Waste Water Treatment, by will regulation adsorption tank, solid-liquid separating machine, fixed interval (FI) filter, facultative aerobic membrane bioreactor and UASB reactors etc. are sequentially communicated setting, and whole technique can be caused to omit biological sludge processing system, and each unit volume is born Lotus anti-impact force is strong, reduces equipment to greatest extent and builds investment;Designed suitable for high concentrated organic wastewater, water inlet allows COD high Up to 20000-100000mg/l.
Brief description of the drawings
Fig. 1 is the schematic flow sheet of high-concentration organic wastewater treatment system of the present invention.
Embodiment
The preferred embodiment of the invention is described in detail below in conjunction with accompanying drawing:
High-concentration organic wastewater treatment system as shown in Figure 1, main regulation adsorption tank 1, solid-liquid separating machine 2, the coagulation of including sink Shallow lake reactor 3, fixed interval (FI) filter 4, facultative aerobic membrane bioreactor 5 and UASB reactors 6 etc..
Wherein, regulation adsorption tank 1 is mainly used in the organic wastewater of input being adjusted absorption, and larger grain is removed with initial filter The debris such as footpath thing or big fibre object.Solid-liquid separating machine 2(Or use sludge dewatering equipment)It is connected with regulation adsorption tank 1, so Organic wastewater can be delivered in solid-liquid separating machine 2 by regulation adsorption tank 1 using suction pump, while to solid-liquid separating machine 2 PAM is added in waste water(Polyacrylamide), the slag charge outward transport desiccation obtained by separation of solid and liquid stacks, the muddy aqueous isolated Then downstream transport.Coagulating sedimentation reactor 3 is connected with solid-liquid separating machine 2, for accepting above-mentioned isolated muddy water Liquid;Treat that above-mentioned isolated muddy aqueous is entered in coagulating sedimentation reactor 3, add PAC thereto(Aluminium polychloride), So that PAC and the abundant coagulating sedimentation of muddy aqueous.Fixed interval (FI) filter 4(It is different from Varied clearance filter)It is anti-with coagulating sedimentation Answer device 3 to be connected, for accepting the organic wastewater of above-mentioned fully coagulating sedimentation, and it is fully filtered.And oxygen film biology Reactor 5 is connected with fixed interval (FI) filter 4, and it receives the aqueous that fixed interval (FI) filter 4 exports(That is waste water), so that The aqueous of reception is reacted with the characteristic biology in facultative aerobic membrane bioreactor 5, is dioxy by the contaminant degradation in waste water Change the inorganic substances such as carbon and water, while nutrient source of the thalline to become feeble and die again as other bacteriums is decomposed metabolism, up to whole generations Thank and reach dynamic equilibrium for inorganic matter.UASB reactors 6 are connected with facultative aerobic membrane bioreactor 5, for by simultaneous oxygen film life The sewage that thing reactor 5 inputs carries out anaerobic reaction with further decomposing organic matter, the water discharge UASB reactors 6 after clarification. Contact oxidation reactor 7 is connected with UASB reactors 6, and the sewage for being inputted to UASB reactors 65 carries out biodegradation, The pollutants such as CODcr, BOD5, NH3-N in sewage can be effectively removed in contact oxidation reactor 7, while can also be taken off Oxygen, dephosphorization etc..More medium filter 8(It is preferred that use high flux more medium filter)It is connected with contact oxidation reactor 7, it Filtered for the water outlet to contact oxidation reactor 7;Anti-pollution reverse-osmosis machine 9 is then connected with more medium filter 8, from And the water outlet after above-mentioned filtering is enabled to obtain the standard of discharge purified water.Sludge homogeneous pond 10 respectively with and oxygen membrane biological reaction Device 5 is connected with UASB reactors 6, and is also connected with regulation adsorption tank 1, for collecting the He of facultative aerobic membrane bioreactor 5 Caused a small amount of dirt is to reach the concentration for also being expected to flow back in UASB reactors 6, so as to be back to regulation adsorption tank 1 In, be so advantageous to improve the treatment effect to sewage.Blower fan 11 respectively with coagulating sedimentation reactor 3 and oxygen membrane biological reaction Device 5 is connected with contact oxidation reactor 7, for be aerated to it with promote the oxidation of the growth of microorganism and pollutant drop Solution.In the present embodiment, more medium filter 8 is also connected with regulation adsorption tank 1, so as to obtain the filtering of the fruit of more medium filter 8 Caused dirt can be back in regulation adsorption tank 1, to improve the treatment effect to sewage.
Such high-concentration organic wastewater treatment system water inlet allows COD to be up to 20000 ~ 100000mg/l;It is preferred that use High load capacity is multistage and reaction designing is matched somebody with somebody in the anti-device of oxygen, the high volumetric loadings of 10kg/m2, remarkable pole, and system possesses superpower shock resistance Load-bearing capacity;It is preferred that using efficient UASB reactors, biogas effectively caused by collection reative cell, sludge in reative cell is sufficiently separated Particle, volumetric loading are up to 7kg/m2;Sludge dewatering efficiency high, moving plate spiral type sludge dehydrator, coordinate the spy selected meticulously Kind flocculant, substantially reduces moisture percentage in sewage sludge to less than 70%;System refines, and integrated level is high:Whole technique can omit biological sludge Processing system, each unit volumetric loading anti-impact force is strong, reduces equipment to greatest extent and builds investment.
