Description

A kind of sewage disposal device
Technical field
The invention belongs to technical field of energy saving and environmental protection, specially a kind of sewage disposal device.
Background technique
The sanitary sewage in city, industrial wastewater etc. can be effectively treated in sewage disposal device, avoid sewage and pollutant direct Waters is flowed into, is of great significance to improving the ecological environment, promoting city taste and promote economic development.Modern sewage handles skill Art is divided by degree for the treatment of, can be divided into level-one, second level and tertiary treatment.Coagulation, main remove is in suspended state in sewage Solid pollution substance, physical treatment process largely can be only done the requirement of coagulation.By the sewage of coagulation, BOD It is general to can remove 30% or so, discharge standard is not achieved.Coagulation belongs to the pretreatment of two stage treatment.Two stage treatment is mainly gone Except the organic pollution materials (BOD, COD substance) in sewage being in colloid and dissolved state, removal rate makes organic up to 90% or more Pollutant reaches discharge standard.Tertiary treatment, being further processed organic matter difficult to degrade, nitrogen and phosphorus etc. can result in water body richness battalion The soluble inorganic matter etc. of feedingization.Main method has a biological carbon and phosphorous removal method, coagulant sedimentation, sand filtration method, active carbon adsorption, Ion-exchange and electric osmose analytic approach etc..
Film-bioreactor (Membrane Bio-Reactor, MBR) is that membrane separation technique and biologic treating technique are organic In conjunction with novel state waste water treatment system.Replace traditional biological processing technique end secondary settling tank with membrane module, in bioreactor Middle holding high activity sludge concentration improves biological treatment organic loading, to reduce sewage treatment facility occupied area, and passes through Low sludge loading is kept to reduce surplus sludge volume.Main activated sludge and macromolecular using in membrane separation plant trap water is organic Object.Activated sludge (MLSS) concentration can be promoted to 8000 ~ 10,000mg/L in membrane bioreactor system, even higher;Sludge Age (SRT) can extend to 30 days or more.It is longer micro- can to retain the generation cycle because of its effective crown_interception for membrane bioreactor Biology is, it can be achieved that Simultaneous Nitrification bacterium can sufficiently breed in system, and nitrification effect is obvious, to depth to deep purification of waste water Dephosphorization denitrogenation provides may.
Summary of the invention
Present invention aims to overcome that deficiency in the prior art, provides a kind of sewage disposal device.
Sewage disposal device of the present invention includes water inlet pipe, be sick of pond, aeration tank, membrane biological reaction pond, membrane module, suction Pump, the membrane biological reaction pond are arranged in the aeration tank;The aeration tank is arranged in the lonely pond, the water inlet pipe Lead to the lonely bottom of pond portion, the membrane module is arranged in the membrane biological reaction pond, and the top of the membrane module passes through company Fishplate bar connects the top in the membrane biological reaction pond, and a vibrating motor is fixed at the top of the membrane module, and the membrane module connects Connect the suction pump;The bottom in the membrane biological reaction pond is provided with lateral filter layer, is connected to institute by the lateral filter layer Aeration tank and the membrane biological reaction pond are stated, the side wall upper part of the aeration tank is provided with longitudinal filter layer, passes through the longitudinal direction Filter layer is connected to the lonely pond and the aeration tank;There is an air blower to connect aeration tube, the aeration tube is horizontally installed on cross To between filter layer and the aeration tank;The longitudinal direction filter layer is made of cellular activated carbon;It is described transverse direction filter layer by grain The zeolite filler that the walnut shell filtering material and partial size that diameter is 1.25-1.60mm are 2-2.5mm is mixed by weight 4:11.It is sick of Pond, aeration tank, membrane biological reaction pond top edge height are identical.
As optimization, Zhengzhou Qi Xin water-purifying material Co., Ltd hole internal diameter 4-5mm is selected, through the water-fast bee of diameter 0.5-0.7mm Nest active carbon;The walnut shell filtering material and partial size that the macro hair active carbon water process Co., Ltd partial size in Wen County is 1.25-1.60mm are 2- The zeolite filler of 2.5mm.Cangzhou Zhongxin Biological Technology Co., Ltd.'s sewage treatment special bacteria bacterium B is added in lonely pond;It exposes Cangzhou Zhongxin Biological Technology Co., Ltd.'s sewage treatment special bacteria bacterium A is added in gas pond and membrane biological reaction pond.Lonely pond Interior sludge concentration remains 18 ~ 19g/L;Sludge concentration remains 15 ~ 16g/L in aeration tank.Sludge is dense in membrane biological reaction pond Degree remains 12 ~ 13g/L.
Sewage disposal device of the present invention, using lonely pond, aeration tank, membrane biological reaction pond nested design knot one by one Structure, intensive optimization take up little area;Lonely pond is connected to aeration tank by longitudinal filter layer simultaneously;By the useless of anaerobic bio-treated Water enters in aeration tank after the filtering of longitudinal filter layer;Aeration tank is connected to membrane biological reaction pond by lateral filter layer; The waste water handled by aeration and biological enters membrane biological reaction pond by lateral filter layer and carries out secondary aeration reaction, passes through film group Filtered waste water is extracted out by suction pump after part filtering.By the way that vibrating motor, vibrating motor band is arranged at the top of membrane module Dynamic membrane module vibration, so that the pollution for reducing membrane module enhances the service life of membrane module;The lateral mistake that the present invention passes through optimization The filtering of filtering layer and longitudinal filter layer and dual aeration reaction;When substantially increasing sewage treatment, sludge concentration in pond Concentration and the efficiency of anaerobic organism reaction and aeration and biological reaction.The intensive design of the present invention, operation control is simple, land occupation Area is small, and reliability and treatment effeciency are high;Especially to TP(total phosphorus) processing there is effect very outstanding, outlet effect is high In higher than GB18918-2002 " urban wastewater treatment firm pollutant emission standard " level-one A standard.
