Abstract

The invention discloses a system for removing nitrogen and phosphorus in sewage and an operation method of the system. The system comprises a water inlet, an anaerobic tank, an anoxic tank, an aerobic tank, a sedimentation tank and a water outlet. The operation method comprises the following steps: firstly, opening a container to enable immobilized microbial balls to flow into the system; then collecting the immobilized microbial balls with long service time; finally, remanufacturing the collected immobilized microbial balls. The immobilized microbial balls used in the system for removing nitrogen and phosphorus in sewage and the operation method of the system can not only maintain the activity of microbes but also separate mud from water and have excellent settleability; the diameters of the immobilized microbial balls are appropriately selected, so that suspension can be realized without a relatively large magnetic field, and sewage can be in contact with the microbes in the immobilized microbial balls; the magnetic field acts to enable the immobilized microbial balls to be in the suspended state, and can also improve the microbial activity; the immobilized microbial balls can be recycled, so that microbes in the immobilized microbial balls are always in a high-activity state.

Description

Sewage goes to denitrogenate the system with phosphorus and operational approach thereof
Technical field
The present invention relates to sewage treatment area, specially sewage goes to denitrogenate the system with phosphorus and operational approach thereof.
Background technology
China is the most unbalanced country of distribution of water resources, and the water resource that each place has is the most unbalanced, totally On be a hydropenia country, the whole nation has the city of 70% to be in exsiccosis;China or a with serious pollution state of water simultaneously Family, annual because water pollutes the loss caused accounts for the 2% of GDP, water pollution condition is constantly aggravated so that sewage disposal and regeneration Industry is by unprecedented concern.
Being mainly used in anaerobic pond discharging phosphorus, partial organic substances carries out ammonification simultaneously, also can remove the COD in water, pass through Interior circulation can be by the mixed-liquor return of anoxic pond to anaerobic pond, and the part immobilized microorganism ball in anaerobic pond is by sedimentation tank Backflow comes;Being mainly used in denitrogenation in anoxic pond, nitrate nitrogen is back to anoxic pond by interior circulation by Aerobic Pond;Aerobic Pond is used In removing BOD, ammonia and nitrogen organic and nitrification and absorption phosphorus in water, Organic substance in water is decomposed into inorganic matter;Sedimentation tank is used for Purifying water, the water after sedimentation tank precipitates can be expelled directly out.
The effect of detention tank is mainly mud-water separation, and the conventional method used is free sedimentation, flocculation sediment, collection Group's precipitation and compression precipitating, but the method for each precipitation has respective shortcoming, or the sedimentation time is oversize, or mud-water separation Not thorough, settleability is bad.
Summary of the invention
It is an object of the invention to provide sewage to go to denitrogenate the system with phosphorus and operational approach thereof, to solve above-mentioned background skill The problem proposed in art.
For achieving the above object, the present invention provides following technical scheme: sewage goes to denitrogenate the system with phosphorus, including entering water Mouth, anaerobic pond, anoxic pond, Aerobic Pond, sedimentation tank and outlet;Sewage enters from water inlet, passes sequentially through anaerobic pond, anoxia Pond, Aerobic Pond, sedimentation tank, finally discharge from outlet, and the described mixed liquor in Aerobic Pond can be back to anoxic pond, anoxia Mixed liquor in pond can be back to anaerobic pond, and the immobilized microorganism ball part in described sedimentation tank is back to anaerobism Pond, another part is discharged;
Described anaerobic pond includes outlet pipe, water inlet pipe, container and magnetic field generator;Described anoxic pond and Aerobic Pond are wrapped Include water pipe, water inlet pipe, magnetic field generator, return duct and aerator;Described sedimentation tank include outlet pipe, water inlet pipe, Return duct and collection device;
Described container is used for containing immobilized microorganism ball;The bottom of described sedimentation tank is provided with collection device, is used for collecting Immobilized microorganism ball;The bottom of described sedimentation tank connects back to flow tube, for by the immobilized microorganism ball backflow of a part To anaerobic pond;
Described immobilized microorganism bag includes magnetizing mediums and activated sludge, described magnetizing mediums without magnetic, but can Magnetizing under the influence of a magnetic field, described activated sludge is rich in microorganism;Described activated sludge is wrapped in magnetizing mediums, shape Glomeration;Described magnetic field generator produces magnetic field, and then makes immobilized microorganism ball go to denitrogenate and phosphorus at described sewage System is in suspended state.
Preferably, it is to pass through with recovery that described sewage goes to denitrogenate the preparation with the immobilized microorganism ball in the system of phosphorus Will be enriched in the activated sludge of microorganism by solvent be dissolved into thick after be sufficiently mixed with magnetizing mediums, then mixture is passed through mould Tool be fabricated to bead go forward side by side sector-style do;Bead after air-drying again is placed among magnetic field, and under the active force in magnetic field, inside is contained The bead of magnetizing mediums does not contains the bead of magnetizing mediums and separates with inside, and the internal bead containing magnetizing mediums is immobilized microorganism Ball;Immobilized microorganism ball is used for described sewage go to denitrogenate with in the system of phosphorus, and goes to denitrogenate and phosphorus at described sewage System around by arrange magnetic field generator produce magnetic field, make immobilized microorganism ball go to denitrogenate and phosphorus at described sewage System is in suspended state;Immobilized microorganism ball is in long-time use, and the activated sludge on surface loses activity gradually, stream Enter to surrounding the immobilized microorganism ball being not provided with in the sedimentation tank in magnetic field to sink to bottom by the gravity of self and carry out back Receiving, finally pass through to soak by the immobilized microorganism ball reclaimed, roll, centrifugal mode reclaims magnetizing mediums;To be recovered to again Magnetizing mediums and activated sludge are sufficiently mixed makes immobilized microorganism ball again.
Preferably, a diameter of 2 ~ 8mm of described immobilized microorganism ball.
Preferably, described magnetizing mediums is metallic nickel.
Preferably, described metallic nickel is the metallic nickel after Passivation Treatment.

4th step, sewage are discharged after described sewage goes to denitrogenate and precipitates with the sedimentation tank (5) in the system of phosphorus;Immobilization is micro- Biological ball (7) is not provided with magnetic field around being flowed into after described sewage goes to denitrogenate and use a period of time in the system of phosphorus In sedimentation tank (5), sink to sedimentation tank (5) bottom by the gravity of self, and enter in collection device (14), part immobilization Microorganism ball is back in anaerobic pond (2) by return duct (12).
