Description
Technical Field
The invention relates to the technical field related to sewage treatment, in particular to a dephosphorization carrier and a dephosphorization method for sewage treatment equipment.
Background
The nitrogen and phosphorus nutrient elements in the water body are the main causes of water body eutrophication. Wherein the phosphorus in the water body mainly comes from sewage discharged into the water body. Therefore, removing phosphorus from wastewater is an important way to improve the water environment.
At present, the phosphorus removal method for domestic sewage mainly comprises chemical phosphorus removal, electrochemical phosphorus removal and biological phosphorus removal. Wherein, biological phosphorus removal needs to construct alternate anaerobic and aerobic links, phosphorus is excessively taken by phosphorus accumulating bacteria in an aerobic state, and phosphorus in sewage is removed by discharging phosphorus-rich excess sludge. Because the biological phosphorus removal process is controlled complicatedly, the biological phosphorus removal process is generally applied to less sewage treatment equipment.
Chemical phosphorus removal refers to the process of adding a chemical agent to form insoluble phosphate precipitate and then removing phosphorus from sewage through solid-liquid separation. The conventional chemical phosphorus removal needs to be provided with a dosing facility or equipment, including a medicament storage device, a medicament dissolving and dosing device, a medicament mixing and flocculating device and other measures, which undoubtedly can greatly increase the cost.
The chinese patent application No. 201410624036.7 provides a phosphorus removal method for sewage treatment equipment, which adopts a slow-release phosphorus removal agent installed on a return pipe of the sewage treatment equipment, and does not need a specially-assigned person to administer the phosphorus removal agent on duty. But the disadvantages are that in the implementation process:
1. an additional medicament barrel or other modes are needed to store and install the slow-release phosphorus removal agent in the sewage treatment equipment;
2. chemical phosphorus removal generally requires a medicament mixing process, and the slow-release phosphorus removing agent is only dissolved by utilizing the tiny power of gas stripping reflux liquid in a mode of installing the slow-release phosphorus removing agent on a reflux pipe of sewage treatment equipment, so that the phosphorus removing agent is not beneficial to realizing the complete mixing of the phosphorus removing agent and water, and the utilization rate of the phosphorus removing agent is low;
3. the mode of installing the slow-release phosphorus removing agent on the return pipe of the sewage treatment equipment limits the storage amount of the slow-release phosphorus removing agent, and the frequent addition of the phosphorus removing agent is easily caused;
4. the preferable conditions of chemical phosphorus removal are low SS and low DS environments, and the mode of refluxing the phosphorus removing agent and the reflux liquid to the previous process often causes that the investment environment of the phosphorus removing agent is not suitable (high SS and high DS environments) and the waste of the phosphorus removing agent is easily caused.
Electrochemical phosphorus removal adopts an electrolysis mode, iron ions or aluminum ions are generated by utilizing electric energy electrolysis to generate insoluble phosphate precipitate, and then phosphorus is removed from sewage through solid-liquid separation. The method has the defects that the electrolysis polar plate needs to be frequently replaced, and the energy consumption of the electrolysis device is higher.
In addition, the existing phosphorus removal methods are all not suitable for upgrading and modifying existing sewage treatment equipment because additional phosphorus removal devices need to be installed and are limited by installation space, power consumption and the like.
Therefore, how to design a phosphorus removal device which is convenient to be adopted in the existing sewage treatment equipment, has long service time and low maintenance frequency and does not need to modify the sewage treatment equipment is a problem which needs to be solved by the technical personnel in the field.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a dephosphorization carrier for sewage treatment equipment. According to the invention, by designing a brand new structure, the phosphorus removal agent can be suspended in sewage in the process of releasing the phosphorus removal agent, and the phosphorus removal agent floats to the water surface after being used up, so that the existing sewage treatment equipment is not required to be modified, the service cycle is long, and the maintenance is easy.
In order to achieve the purpose, the invention adopts the following technical scheme:
a dephosphorization vector for a sewage treatment plant, comprising:
a shell body, a plurality of first connecting rods and a plurality of second connecting rods,
the inside of the shell is provided with a storage bin for containing a phosphorus removing agent, and the phosphorus removing agent is arranged in the storage bin;
one end of the storage bin is sealed by a bin cover, and the other end of the storage bin is a slow release interface for releasing the phosphorus removing agent;
wherein,
the shell is in a suspension state in the sewage when the phosphorus removing agent is not used up;
the shell is in a floating state in the sewage when the phosphorus removing agent is exhausted.
The phosphorus removal carrier can become a carrier of microorganisms when in use, and chemical phosphorus removal can be realized when the phosphorus removal agent is dissolved. According to different choices, the phosphorus removal agent can adopt solid iron salt or aluminum salt.
Preferably, the phosphorus removal agent is solid polymeric ferric sulfate.
Preferably, a floating body is arranged on one side of the shell close to the bin cover.
Preferably, the slow release interface comprises a microporous plate and a water filtering fabric arranged on the outer side of the microporous plate, and the storage bin is sequentially connected with the microporous plate and the water filtering fabric in a sealing manner;
compared with the center of gravity of the dephosphorization carrier, the position of the metallic iron block is closer to the floating center of the dephosphorization carrier;
namely, the distance between the slow release interface and the center of gravity of the dephosphorization carrier is less than the distance between the slow release interface and the floating center of the dephosphorization carrier.
Preferably, the micropore plate is a stainless steel plate with through holes with the hole diameter of 0.3-0.8 mm.
Preferably, the water-filtering fabric is a nonwoven geotextile.
Preferably, the bin cover and/or the storage bin are iron.
Preferably, the bin cover and/or the storage bin contain metal iron blocks. Compared with the center of gravity of the dephosphorization carrier, the position of the metallic iron block is closer to the floating center of the dephosphorization carrier; namely, the distance between the metal iron block and the center of gravity of the dephosphorization carrier is less than the distance between the slow release interface and the floating center of the dephosphorization carrier.
Preferably, a floating body is disposed on the housing.
Preferably, the floating body is positioned at one side close to the bin cover in the shell, and the floating body enables the gravity center and the floating center of the dephosphorization carrier not to coincide.
When the phosphorus removing agent is stored in the shell, the density is 0.94-0.97g/cm3When the phosphorus removing agent is exhausted, the density is 0.80-0.90g/cm3。
The dephosphorization carrier can automatically float to the water surface when the dephosphorization agent is exhausted through the density difference, so that the maintenance personnel can conveniently identify and supplement.
While providing the structural scheme, the invention also provides a method for utilizing the phosphorus removal carrier, which mainly comprises the following steps:
A. opening the bin cover, and adding a phosphorus removing agent into the storage bin;
B. closing the bin cover, and throwing the shell into a sewage treatment tank;
C. the shell is suspended in the sewage, and after the phosphorus removing agent is exhausted, the shell floats on the water surface;
D. and fishing out the shell by using a magnet, and reloading the phosphorus removing agent.
The invention has the beneficial effects that:
(1) can be directly widely applied to sewage treatment equipment to replace or supplement the existing carriers. The sewage treatment equipment without the phosphorus removal function can be improved without great improvement and additional dosing facilities or equipment, so that the sewage treatment equipment without the phosphorus removal function has the phosphorus removal function.
(2) The physical slow release of the phosphorus removing agent is realized by the microporous material and the water-filtering type fabric, and compared with a phosphorus removing agent (such as a slow release phosphorus removing agent) adopting chemical slow release, the phosphorus removing agent capable of being stored has higher purity (the slow release phosphorus removing agent and the like need to be added with additional slow release raw materials, and the phosphorus removing agent is often diluted), so that the capacity is larger, the service time is longer, and the maintenance frequency is lower.
(3) The shell is in a suspension state when containing the phosphorus removing agent, and automatically floats out of the water surface when the phosphorus removing agent is exhausted, so that the content of the phosphorus removing agent in the shell does not need to be frequently observed, and the method is very convenient.
(4) No additional power supply is required for the phosphorus removal process.

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings.
Example (b): a dephosphorization carrier for sewage treatment equipment, the structure of which is shown in fig. 1-3, fig. 6 and fig. 7, comprising:
has a housing 1 for attachment of a biofilm; a storage bin 2 for storing a phosphorus removing agent 4 is arranged in the shell 1;
the shell 1 should be selected as spherical as possible to control the center of gravity and the center of buoyancy.
Two ends of the storage bin 2 are respectively provided with a bin cover 3 and a slow release interface 5;
the bin cover 3 can be opened and closed and is used for supplementing a phosphorus removing agent 4;
the bin cover 3 is made of metal iron, the surface of the bin cover is plated with nickel, and metal iron blocks can be contained inside the bin cover;
the phosphorus removing agent 4 adopts solid high-molecular polymeric ferric sulfate;
the slow release interface 5 is the only contact interface between the phosphorus removing agent 4 in the storage bin 2 and water around the phosphorus removing carrier;
the slow release interface 5 is a 2-layer composite structure consisting of a microporous material 6 and a water-filtering fabric 7;
the microporous material 6 is in contact with the phosphorus removing agent 4 and is a stainless steel microporous plate with the thickness of 0.4-0.6mm and the perforation diameter of 0.3-0.8 mm;
the water-filtering type fabric 7 is contacted with water around the dephosphorization carrier and is a water-filtering type non-woven geotextile with the thickness of 0.5-1.0 mm;
a floating body 8 is arranged on one side of the shell 1 close to the bin cover 3.
Wherein, the outer side of the water-filtering type fabric 7 is also provided with a fixing ring 9, and the fixing ring 9 is used for preventing the water-filtering type fabric 7 and the microporous material 6 from falling off.
The floating body 8 is fixed on the shell 1 and is annular. The floating body 8 is used for enabling the gravity center and the floating center of the dephosphorization carrier not to coincide, enabling the bin cover 3 containing the metal iron block (not shown in the figure) to be deviated to the lighter side (namely to the side of the floating center) of the dephosphorization carrier, so that when the dephosphorization agent is exhausted and the dephosphorization carrier automatically floats to the water surface, the dephosphorization carrier is exposed out of the water surface from one side of the bin cover 3 containing the metal iron block, and a maintainer can conveniently utilize the magnet to take out the dephosphorization carrier floating to the water surface from the water.
The slow release interface 5 is positioned on the lighter side (i.e. the side deviated to the center of buoyancy) of the phosphorus removal carrier, when disturbance force such as aeration does not exist in water, the slow release interface 5 is in the direction of facing downwards under the action of buoyancy of the water and the self gravity of the phosphorus removal carrier, and the probability of impurities accumulated on the surface of the slow release interface 5 can be reduced.
The working principle of the invention is as follows: the biofilm carriers are treated with water to store the phosphorous removal agent. The dephosphorization carrier comprises a storage bin 2 for storing a dephosphorization agent. The storage bin 2 can be opened and closed to replenish the phosphorous removal agent 4. The phosphorus removing agent 4 adopts solid iron salt or aluminum salt.
In use, the dephosphorizing agent 4 in the storage bin 2 is in contact with the water around the dephosphorizing carrier only through the slow-release interface 5. The slow release interface 5 is a composite structure of a microporous material and a water-filtering fabric. The microporous material 6 and the drainage fabric 7 allow a slow release of the phosphorous removal agent into the surrounding sewage 10.
The water-filtering fabric 7 also provides a barrier to insoluble impurities in the water, thereby protecting the microporous material 6 from clogging. When the phosphorus removal carrier stores the phosphorus removal agent, the density is close to that of water, when the phosphorus removal agent is exhausted, the density is smaller than that of water, and the phosphorus removal carrier can automatically float to the water surface when the phosphorus removal agent is exhausted so as to be convenient for maintenance personnel to identify and supplement.
Preferably, the position of the floating body 8 is designed to be biased to the side with the metallic iron block (i.e. the upper part of the shell 1) and away from the slow release interface (i.e. the lower part of the shell 1), so that the center of gravity and the center of buoyancy of the phosphorus removal carrier are not coincident. The metal iron block is arranged on the lighter side (i.e. the side deviated to the floating center) of the dephosphorization carrier, so that when the dephosphorization agent is exhausted and the dephosphorization carrier automatically floats to the water surface, the dephosphorization carrier is exposed out of the water surface from one side of the metal iron block, and a maintainer can conveniently utilize the magnet to take out the dephosphorization carrier floating to the water surface from the water.
The slow release interface 5 is arranged on the heavier side (i.e. the side deviated to the gravity center) of the phosphorus removal carrier, and when disturbance force such as aeration does not exist in water, the slow release interface is in the direction of facing downwards under the action of buoyancy and self gravity of the water, so that the probability of impurities accumulated on the surface of the slow release interface can be reduced.
As shown in FIG. 4, when the phosphorus removal carrier is in a suspension state in the use state, i.e. the storage bin stores the phosphorus removal agent 4, the phosphorus removal carrier is in a suspension state.
As shown in FIG. 5, when the phosphorus removal carrier is in a floating state after the phosphorus removal agent stored in the storage bin is exhausted, the phosphorus removal carrier is exposed out of the water surface at one side of the bin cover 3 containing the metal iron blocks, so that maintenance personnel can conveniently take out the phosphorus removal carrier floating on the water surface from the water by using the magnet.
After having adopted above-mentioned structure, this device can directly throw in the sewage treatment pond and carry out the dephosphorization, and need not to reform transform sewage treatment device, also need not to drag for and observes the dephosphorization agent quality, and automatic come-up when the dephosphorization agent exhausts can used repeatedly after replenishing once more.
