FIG. 1 is a schematic structural diagram of a micro-nano biofilter dephosphorization and denitrification treatment device.
Detailed Description
The phosphorous and nitrogen removal treatment device for the micro-nano biological filter provided by the embodiment has a structure shown in fig. 1, and comprises a water collecting tank 1 and an adjusting tank 2, wherein the water collecting tank 1 and the adjusting tank 2 are provided with adjusting pumps 3; still include anaerobism pond 4, oxygen deficiency pond 5, oxidation pond 6 and two heavy ponds 7, two heavy pond 7 bottoms are provided with extraction pump 8, and extraction pump 8 passes through pipeline and 4 intercommunications in the anaerobism pond, is provided with elastic filler 9 in oxygen deficiency pond 5 and the oxidation pond 6.
The secondary sedimentation tank 7 is a vertical sedimentation tank used for solid-liquid separation.
The secondary sedimentation tank 7 is communicated with a micro-nano water purifier 10 which generates negative pressure inside, and the micro-nano water purifier 10 enables sewage and air to be mixed and to be cut in a high-speed rotating mode under the action of pressure.
The micro-nano water purifier 10 is communicated with a C filter 11, and activated carbon filler is arranged in the C filter 11.
The C filter 11 is communicated with a disinfection tank 12, the bottom of the disinfection tank 12 is provided with a second extraction pump 13, the second extraction pump 13 is communicated with the C filter 11 through a pipeline, and the opening of the pipeline is close to the bottom of the C filter 11.
In order to make the water flow rapidly to prevent the pollutants in each tank from precipitating too quickly, the treatment device also comprises a fan room 14 with a built-in fan, and the fan room 14 correspondingly inputs air into the regulating tank 2, the anoxic tank 5, the oxidation tank 6 and the C filter 11 through pipelines.
In order to maintain the sterilizing bath 12 to effectively sterilize the water after the treatment, it is necessary to maintain the concentration in the sterilizing bath 12, and therefore, the treatment apparatus further includes a sterilizing device 15, and the sterilizing device 15 supplies the sterilizing water to the sterilizing bath 12 through a pipe.
When the sediment in the secondary sedimentation tank 7 is excessively deposited, the sediment needs to be cleaned, so the processing device also comprises a sludge tank 16, and the sludge tank 16 is communicated with the first extraction pump 8 in the secondary sedimentation tank 7 through a pipeline.
The working process of the processing device is as follows: at first, the domestic sewage in the ballast area is collected to a sewage treatment station through a drainage channel, then enters a water collecting tank 1, and is lifted by an adjusting pump 3 to enter an adjusting tank 2 for adjusting the quality and quantity of the wastewater.
The effluent of the adjusting tank 2 is quantitatively lifted to a certain height by a pump, the water enters an anaerobic tank 4, an anoxic tank 5, an oxidation tank 6 and a secondary sedimentation tank 7, a first extraction pump 8 reversely pumps the phosphorus-containing sludge sewage in the secondary sedimentation tank 7 back to the anaerobic tank 4, the anaerobic tank 4 releases phosphorus, the concentration of P in the sewage is increased, and the concentration of dissolved organic matters is absorbed by microbial cells to reduce the BOD5 concentration in the sewage; in addition, NH3-N was partially removed by cell synthesis, resulting in a decrease in NH3-N concentration in the wastewater, but NO change in NO3-N content. In the anoxic pond 5, the denitrifying bacteria take organic matters in the sewage as a carbon source, carry a large amount of NO3-N and NO2-N into the backflow mixed liquid, reduce the backflow mixed liquid into N2 and release the N2 to the air, so that the BOD5 concentration is reduced, the NO3-N concentration is greatly reduced, and the change of phosphorus is small. The wastewater passing through the anoxic pond 5 enters the contact oxidation pond 6 under the action of gravity flow, and as the elastic fillers 9 are arranged in the contact oxidation pond 6, the functional microorganisms attach to the surfaces of the elastic fillers 9, utilize organic pollutants in the wastewater as a carbon source and an energy source for self growth and propagation, absorb nitrogen and phosphorus in the wastewater as a nutrient source for self growth, and remove the organic pollutants in the wastewater in the process of continuous growth and propagation of the microorganisms.
Meanwhile, because the wastewater contains a large amount of nitrifying bacteria, under aerobic conditions, the nitrifying bacteria use oxygen as an electron acceptor to oxidize ammonia nitrogen in the wastewater into nitrite state and nitrate nitrogen. Because the biomembrane attached on the elastic filler 9 has a certain thickness, the microorganism in the innermost part of the biomembrane is in an anoxic or even anaerobic environment because of the influence of oxygen mass transfer efficiency, under the environment condition, the denitrifying bacteria in the biomembrane can utilize the organic pollutants in the wastewater as carbon sources to sequentially reduce the nitrate nitrogen in the wastewater into nitrite nitrogen and release the nitrogen into the atmosphere, thereby achieving the aim of denitrification, finally realizing synchronous nitrification and denitrification in the same reaction tank, saving the treatment structure required by the process and saving the cost. For removing phosphorus in the wastewater, a biological phosphorus removal technology is adopted. Under the condition of good nutrition, the phosphorus-removing bacteria can absorb a large amount of phosphorus in the wastewater and store the phosphorus in the cells so as to achieve the purpose of removing the phosphorus in the wastewater.
After anaerobic, anoxic and secondary contact oxidation degradation, organic pollutants and nitrogen and phosphorus in the wastewater are basically degraded to be below the emission standard. However, since the microorganisms have a certain life cycle, once the life cycle is over, the activity of the microorganisms is reduced and the microorganisms fall off the elastic packing 9 under the scouring action of the water flow and the water flows out of the treatment structure together with the water. Therefore, to ensure that the percentage of the effluent reaches the standard, the effluent of the secondary contact oxidation tank 6 enters the secondary sedimentation tank 7 for further treatment. Under the general condition (the effluent reaches the standard), no medicament is required to be added into the secondary sedimentation tank 7. When the water quality deteriorates, in order to increase the stability of the effluent of the system to reach the standard, the content of phosphorus in the wastewater can be further reduced by adding a proper coagulant, and meanwhile, the colloid in the wastewater is coagulated into large-particle substances, so that the solid-liquid separation is convenient in the precipitation process, the suspended solid in the wastewater is removed, and the standard discharge is ensured. In consideration of the wastewater volume and convenience of operation in the future, the secondary sedimentation tank 7 adopts a vertical flow type secondary sedimentation tank 7 for solid-liquid separation.
After solid-liquid separation is carried out in the secondary sedimentation tank 7, the effluent of the secondary sedimentation tank 7 automatically flows to the micro-nano water purifier 10. The micro-nano water purifier 10 adopts a rotary type mixing and cutting principle, sewage entering the water purifier is mixed with air and subjected to high-speed rotary cutting under the action of pressure, a negative pressure shaft is formed in the middle of a generator, the air in the sewage is concentrated on the negative pressure shaft by utilizing the suction force of the negative pressure shaft, and when the sewage and the air rotating at high speed are instantly sprayed out from a spray opening under proper pressure, high-speed and powerful shearing and high-frequency pressure variation are generated on a gas-liquid contact interface due to the mechanical multiplication effect of the ultrahigh rotating speed of mixed gas-liquid at the spray opening and the gas-liquid density ratio, so that artificial extreme conditions are formed. Under the condition, a large amount of micron-sized and nanometer-sized bubbles are generated, meanwhile, the polymeric molecular groups are broken, the effect of forming small molecular group active water is achieved, free radical ions such as active oxygen, oxygen ions, hydrogen ions and hydroxide ions can be generated in the micron-sized and nanometer-sized bubbles, particularly, the hydroxide radical has ultrahigh reduction potential, the ultra-strong oxidation effect is achieved, residual organic impurities in water can be effectively decomposed, the outlet water of the micro-nano water purifier 10 automatically flows into the C filter 11, organic matters in the water are removed by utilizing the adsorption performance of active carbon and the biodegradation effect of a biological film attached to the surface of active carbon filler, and the purpose of purifying the water quality is achieved, so that the final outlet water can meet the requirement of a discharge standard.
After being treated by the C filter 11, various pollution indexes in the wastewater can completely reach the discharge standard. However, considering that the wastewater may contain certain harmful microorganisms such as pathogenic bacteria, in order to ensure that the hygienic index of the effluent reaches the corresponding discharge standard, the wastewater should be disinfected before being discharged into the receiving water body.
In addition to the above embodiments, the present invention may have other embodiments. All technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope of the claims of the present invention.
