A purification device for removing phosphorus from sewage comprises a sedimentation tank 1, a phosphorus removal tank 2 and a water delivery pipe 3, wherein a first water inlet 11 and a first water outlet 12 are arranged at the upper part of the sedimentation tank 1, a trash rack 4 is arranged at the first water inlet 11 of the sedimentation tank 1, the phosphorus removal tank 2 is provided with a second water inlet 21 and a second water outlet 22, the second water inlet 21 is arranged at the top of the phosphorus removal tank 2, the second water outlet 22 is arranged at the bottom of the phosphorus removal tank 2, two ends of the water delivery pipe 3 are respectively connected with the first water outlet 12 of the sedimentation tank 1 and the second water inlet 21 of the phosphorus removal tank 2, quartz sand 5, water hyacinth biological carbon 6 and zeolite 7 are sequentially paved in the phosphorus removal tank 2 from bottom to top, and the mass ratio of the water hyacinth biological carbon 6 to the quartz sand 5 is 1-2: 100.
The utility model discloses a set up sedimentation tank 1 and dephosphorization pond 2, the sewage deposits in the sedimentation tank 1 through the first water inlet 11 entering sedimentation tank 1 earlier during concrete during operation, make mud impurity etc. in the sewage deposit to sedimentation tank 1 bottom under self action of gravity, then the clear solution on sedimentation tank 1 upper portion rethread first delivery port 12 and raceway 3 flow in dephosphorization pond 2, then loop through zeolite 7 inside dephosphorization pond 2, discharge from the second delivery port 22 of bottom behind the filtration purification of water hyacinth biological carbon 6 and quartz sand 5. The utility model discloses a purifier simple structure, purifying effect is good. Wherein, the trash rack 4 is used for intercepting the impurity with larger volume in the sewage and primarily filtering the sewage. Tests show that when the mass ratio of the water hyacinth biochar 6 to the quartz sand 5 is 1-2:100, preferably 1.5:100, the phosphorus removal effect of the purification device is better.
The specific water hyacinth biochar 6 is prepared by cutting dried water hyacinth into blocks, putting the water hyacinth blocks into a vacuum closed container, putting the container into a vacuum calcining furnace for anaerobic pyrolysis, keeping the constant temperature pyrolysis for two hours after the temperature in the vacuum calcining furnace rises to 500 ℃, finally closing the vacuum calcining furnace, taking out the container containing the water hyacinth blocks after the temperature in the furnace is cooled to room temperature, and grinding the water hyacinth blocks to obtain the water hyacinth biochar 6, wherein the prepared water hyacinth biochar 6 has a good phosphorus removal effect.
Wherein, in order to improve the sludge settling speed of sedimentation tank 1, improve sewage purification efficiency, add the flocculating agent in sedimentation tank 1, the flocculating agent can make the quick flocculation agglomeration of particulate matter in the sewage, more is favorable to particulate matter's quick settlement.
The particle size of the zeolite 7 is smaller than 8mm, the zeolite 7 has a large specific surface area and good ion exchange performance, and molecules with a certain size are allowed to move freely, so that the zeolite 7 has good adsorption performance on liquid, and partial impurities in the sewage can be absorbed through the zeolite 7 layer by arranging the zeolite 7 layer in the phosphorus removal tank 2, so that the sewage is purified for one time. When the particle size of the zeolite 7 is larger than 8mm, the gap between the zeolite 7 and the zeolite 7 is too large, which is not beneficial to the primary purification treatment of the sewage by the zeolite 7 layer. On the other hand, the gaps between the zeolites 7 are too large, so that the sewage can rapidly flow through the zeolite 7 layer, the contact time of the zeolite 7 layer and the sewage is shortened, the impurities in the sewage cannot be fully absorbed by the zeolites 7, and the purification effect is further influenced.
The particle size of the quartz sand 5 is smaller than 6mm, when the particle size of the quartz sand 5 is larger than 6mm, gaps between the quartz sand 5 are too large, so that the water hyacinth biological carbon 6 on the upper part of the quartz sand 5 is easily mixed with the quartz sand 5 through the gaps between the quartz sand 5, and the flowing speed of sewage is easily too large due to the too large gaps between the quartz sand 5, so that the contact time of the sewage and the water hyacinth biological carbon 6 is too short, and the phosphorus removal effect of the water hyacinth biological carbon 6 is further influenced. On the other hand, the overlarge gaps between the quartz sand 5 are not beneficial to the absorption or separation of impurities in the sewage by the quartz sand 5 layer, and the purification effect of the sewage can be affected as well.
The water conveying pipe 3 is connected with a water pump 8 used for conveying the water pump 8 in the sedimentation tank 1 to the dephosphorization tank 2, so that a worker can convey supernatant in the sedimentation tank 1 to the dephosphorization tank 2 conveniently, and the purification efficiency is improved.
Wherein, the bottom of sedimentation tank 1 is equipped with drain 13, drain 13 department is equipped with the blowoff valve 14 that is used for controlling the opening and closing of drain 13, through setting up drain 13 and blowoff valve 14, makes the mud in the sedimentation tank 1 can discharge through the drain 13 of sedimentation tank 1 bottom, and during the mud in the staff clearance sedimentation tank 1, need not get into sedimentation tank 1 and transport out mud, only need open drain 13 and cooperate suitable clear water and can clear away the mud of sedimentation tank 1 inside, and it is convenient to wash, and is efficient.
The bottom of the sedimentation tank 1 is provided with a guide surface 15, the guide surface 15 is gradually inclined downwards from one side far away from the sewage draining outlet 13 to one side close to the sewage draining outlet 13, and the sewage draining outlet 13 is communicated with the bottommost end of the guide surface 15. The inclined guide surface 15 ensures that when the sludge in the sedimentation tank 1 is discharged, the sludge can flow to the sewage discharge outlet 13 along the inclined direction of the guide surface 15 and is discharged, so that the sewage discharge efficiency can be improved, and the residual sludge amount in the sedimentation tank 1 after cleaning can be reduced.
Wherein, in order to further improve the discharge efficiency of mud, drain 13 is connected with and is used for taking the mud in the sedimentation tank 1 out of mud pump 9 outside the sedimentation tank 1.
The first filter screen 16 is arranged at the first water outlet 12, so that water precipitated and purified in the sedimentation tank 1 is filtered by the first filter screen 16 and then flows into the dephosphorization tank 2, and the dephosphorization efficiency is improved.
The second filter screen 23 is arranged at the second water outlet 22, the second filter screen 23 can perform filtering and purifying functions, and meanwhile, the quartz sand 5 in the dephosphorization tank 2 can not flow out of the second water outlet 22 along with running water.
While the preferred embodiments of the present invention have been described, the present invention is not limited to the above embodiments, and those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and such equivalent modifications or substitutions are intended to be included within the scope of the present invention as defined by the appended claims.
