Technical field
The present invention relates to a kind of industrial waste water purifying field, a kind of water purification installation using immobilized microorganism plate.
Background technology
Industrial wastewater generally uses biological treatment.But, temperature is to importants such as growth, breeding, metabolism, species distribution and the population quantities of microorganism, and then affects sewage treating efficiency.Additionally, the flocculation viscosity of activated sludge performance and waste water is had a great impact by temperature.
Along with the increasingly stringent of effluent-disposal standard, traditional process for treating industrial waste water cannot meet requirement.The most under cryogenic, the metabolic capacity of microorganism reduces, and chemical reaction rate also can reduce.Therefore, the efficiency of biological treatment waste water also can reduce.
Traditional activated sludge process is applied widely in sewage disposal, it is primarily due in activated sludge containing substantial amounts of active microorganism, the Organic substance in sewage can be fast and effeciently removed in these microorganisms, and have good Nitrogen/Phosphorus Removal, but traditional activated sludge process mud is blended in sewage and is in a kind of fluidised form.At present, obtain immobilized microorganism technology paying close attention to widely, such as Patent No. both at home and abroad: 200910056687.X patent specification describes a kind of immobilized microorganism preparation method;Immobilized microorganism is mainly characterized by Microorganism incubation and becomes a kind of solid-state, is placed in sewage and has fixing shape, and microorganism not loss of activity, has good wastewater treatment efficiency.
Immobilized microorganism and magnetic field are mainly applied in sewage disposal by the present invention simultaneously, under cryogenic, increasing the action effect of microorganism, microorganism has aerobic and anaerobism alternate environment, simultaneously because microorganism is in immobilized state, therefore can effectively prevent fouling membrane.
Summary of the invention
It is an object of the invention to, it is provided that a kind of water purification installation using immobilized microorganism plate, immobilized microorganism, the aerobic-anaerobic of microorganism and magnetic field are combined.
For achieving the above object, the present invention provides following technical scheme: a kind of water purification installation using immobilized microorganism plate, including apparatus for treating sewage, immobilized microorganism system and membrane module, described apparatus for treating sewage upper end is provided with water inlet, immobilized microorganism system it is provided with in apparatus for treating sewage, described immobilized microorganism system is divided into three layers, being followed successively by the first immobilized microorganism layer, the second immobilized microorganism layer and the 3rd immobilized microorganism layer from outside to inside, described first immobilized microorganism layer is connected by polylith immobilized microorganism plate and forms;nullDescribed immobilized microorganism plate uses the mixture composition of activated sludge and gravel,Activated sludge and gravel are mixed into pasty mixture according to the ratio of 1:3 by chemical reagent,Again pasty mixture is fixed by template,Template is taken off after pasty mixture is dry,Activated sludge after drying and gravel mixture are wound around spiral winding again and form described immobilized microorganism plate,Described immobilized microorganism plate thickness is 3-5cm,The manufacture method of described second immobilized microorganism layer and the 3rd immobilized microorganism layer is identical with described first immobilized microorganism layer manufacturing method thereof,First immobilized microorganism layer、Second immobilized microorganism layer and the 3rd immobilized microorganism layer are all combined closely with bottom apparatus for treating sewage,Described spiral winding is connected with transformator,Transformator is connected with power supply,It is provided with aerator e inside apparatus for treating sewage and between the first immobilized microorganism layer,It is provided with membrane module inside the 3rd immobilized microorganism layer,It is provided with aerator f between described membrane module and the 3rd immobilized microorganism layer,It is provided with outlet in described membrane module,Described outlet connects outlet pipe,Magnetic field tester it is additionally provided with in apparatus for treating sewage,Power supply controls current intensity and the direction of spiral winding by transformator,Thus control the size and Orientation in magnetic field,A variable magnetic field is defined in apparatus for treating sewage,This action of a magnetic field is in immobilized microorganism system,Magnetic field produces magnetic bio effect to the microorganism in immobilized microorganism system,Magnetic field tester detects magnetic field intensity in apparatus for treating sewage,Sewage enters from water inlet and sequentially passes through the first immobilized microorganism layer、Second immobilized microorganism layer、3rd immobilized microorganism layer and membrane module,Discharged by the outlet conduit on membrane module.
Preferably, described spiral winding is made up of one layer of plastics of parcel outside iron wire.
Preferably, described membrane module is made up of hollow-fibre membrane.
Compared with prior art, the invention has the beneficial effects as follows: these apparatus and method use magnetic field microbe consolidation system, improve microbial activity by magnetic bio effect.Therefore, overcome the shortcoming that under cryogenic conditions, Conventional waste water processes the unstable and low degradation rate of Organic substance, immobilized microorganism and magnetic field are applied in sewage disposal simultaneously, increasing the action effect of microorganism, microorganism has aerobic and anaerobism alternate environment, simultaneously because microorganism is in immobilized state, therefore fouling membrane can effectively be prevented, the present invention is effectively increased sewage treating efficiency, and floor space is little, and cost of investment is low.
