The present invention relates to an upflow filter equipped with a disinfection facility and developed for multi-purpose use, and more particularly, to a polypropylene-based (EPP) hydrophobic foamed polymer filter medium having a unique shape and material, or a flotethylene-based porous floating polymer filter medium.

Filtration is a typical process for removing particulate contaminants present in water in a water purification process for producing domestic and industrial water and a water treatment process for treating sewage and wastewater.

For example, in a water purification plant, contaminants (phosphate, etc.) contained in raw water are reacted with the coagulant to precipitate in the form of solids (floc) while mixing (mixing) and stirring chemicals (coagulant) with raw water. It is transferred to a sedimentation process, and the water finally purified through a filtration process in a sand filter is used as water.

In the case of sewage and wastewater treatment plants, water that has undergone biological treatment and chemical treatment is usually sent to a sand filter, but the filter media layer is easily clogged with contaminants, so it takes a lot of time and money to backwash it.

In addition, more rotational force may be generated by attaching a wing having a smaller size than that of the rotary wing by screwing or welding to the end of the rotary wing.

The filter medium layer is a material having excellent chemical stability such as acid resistance and alkali resistance as a hydrophobic expanded polypropylene (EPP) floating filter medium in which a filter medium having a thickness of 2.5 mm to 5 mm is disposed.

Hereinafter, a method for removing phosphorus and treating recycled water using an upflow filter for the practice of the present invention will be described in detail.

First, the PAC unit 100 aggregates the water to be treated with a polymer coagulant.

And the number of treatment targets from the PAC unit 100 is primarily filtered.

In addition, the treated water tank 200 secondarily filters the firstly filtered treatment target water.

Subsequently, the line mixer 310 is coupled to mix the pretreated sludge and the coagulant.

In addition, the impeller 320 is rotatably built into the casing of the line mixer, and bounces the sucked foreign matter back into the cyclone airflow.

In addition, the upflow filter 10 filters the foreign matter received from the impeller 320 using a fiber filter medium.

In addition, the stirrer 500 stirs the fiber filter medium and foreign matter through the impeller in the upflow filter 10.

In addition, the flow control tank 400 controls the flow rate discharged from the upflow filter 10 .

In addition, the ultraviolet sterilizer 600 sterilizes the filtered water discharged from the upflow filter 10 with ultraviolet rays.

In addition, the treated water tank 800 stores the filtered water discharged from the upflow filter 10 .

In addition, the reaction coagulation tank 330 introduces a chemical for removing contaminants between the line mixer 310 and the upflow filter 10 into the wastewater and stirs it.

Finally, the ozone destroyer 900 treats the ozone in the reaction coagulation tank 330 .

At this time, the residual ozone destroyer 900 decomposes the residual ozone discharged from the reaction coagulation tank 330 and the residual ozone destroyer 900 according to the pressure of the reaction coagulation tank 330 measured by the pressure sensor. It includes a control unit that regulates the operation.

The fiber filter medium (CFM) of the upflow filter 10 is manufactured using a blend-felt-thermal bonding step.

On the other hand, the above-mentioned floating filter media, floating irregular granular filter media, flotation media, hydrophobic foamed polymer filter media, high-speed hydrophobic foamed polymer filter media, etc. have similar structures to each other, and the present invention may further include an activated carbon filter in addition to this.

In the case of the activated carbon filter, the function of adsorbing turbidity and color causing substances contained in sewage and deodorizing is excellent. In particular, it can effectively adsorb free residual chlorine, trihalomethanes, volatile organic compounds (VOCs) such as chloroform, lead, etc., and also has the ability to remove other amine odors and methyl mercaptan.

The activated carbon filter may be one in which 10 to 50 mesh activated carbon particles are filled with a filter medium and have a thickness of 10 to 150 cm.

At this time, when the activated carbon particle size is less than 50 mesh, the flow rate of the fluid passing through the activated carbon filter may decrease, and when the size exceeds 10 mesh, the deodorization and adsorption function of the activated carbon filter layer may decrease.

In addition, when the activated carbon filter has a thickness of less than 10 cm, adsorption and deodorization functions may be reduced, and when the thickness exceeds 150 cm, the filter unit becomes larger than necessary, and economical efficiency is poor. , it is preferable to use an activated carbon filter in the range described above.

At least one filter selected from the group consisting of sand, garnet, anthracite, zeolite, igneous rock, elvan, garnet, ceramic ball, kaolin clay ball, and ocher ball may be further included at the location where the activated carbon filter is attached.

More specifically, the filter uses an inorganic filter having an excellent function of adsorbing pollutants aggregated in sewage, and a filter having a diameter of 0.5 to 30 mm is used so that the function of adsorbing pollutants is not deteriorated and the size is not larger than necessary. can

Alternatively, an activated carbon filter layer is formed on the filter, and sand particles having an average diameter of 0.5 mm are filled to a thickness of 30 cm to form an inorganic filter material filter layer, and the deoiled horseradish tree (Moringa oleifera Lamarck) seed composite particles to a thickness of 20 cm An organic-inorganic composite filter layer may be formed by filling, and a pre-treatment filter layer may be formed by mounting a synthetic fiber filter made of polypropylene having a thickness of 5 cm.

In addition, the above-mentioned floating filter media, floating irregular granular filter media, floating filter media, hydrophobic foamed polymer filter media, and high-speed hydrophobic foamed polymer filter media are composed of polymer filter plate members coupled to each other through grooves to maintain their geometric structure. In order to do so, a binding member for binding the polymer filter module is further included.

For example, the binding member may be formed by forming a wire, a band, or a material of the same material as the polymer filter plate member in the form of a thread to bind the binding member.

As the sewage passes between the polymer filter plate member of the geometric structure filled inside the filter medium and the polymer filter plate member, the oil component of the fine particles contained in the sewage is deposited on the surface of the polymer filter (i.e., cell-unit polymer filter plate member). Friction is generated while moving in close contact, and the oil components of the fine particles are coalesced, so that the oil components whose size has increased are lifted to the upper part of the treatment tank and removed.

In addition, as the sewage passes through the polymer filter, the solids of fine particles contained in the sewage are closely moved to the surface of the polymer filter (ie, the cell-unit polymer filter plate member), causing friction to cause the solids of fine particles to coalesce. As a result, the solids whose particle size has increased are precipitated to the lower part of the treatment tank and removed.

As described above, the polymer filter of the present invention has a geometric structure having a sewage pipe and a passage therebetween, and the polymer filter plate member of the cell unit expands the surface area due to the geometric structure of the polymer filter plate member to increase the coalescence performance of fine oil components contained in sewage. It improves the removal efficiency of fine oil components by improving the removal efficiency of fine solids by improving the coalescence performance of fine solids contained in sewage.

The above-mentioned filter media or filters are formed through polyester fibers, and have tensile strength and flexibility at the same time by constructing a three-dimensional network structure by self-fusion of cellulose (polyester), and have sound absorption, heat insulation, and light weight by having pores connected to the inside. It has excellent moisture stability, which is a unique characteristic of polyester fiber, so sewage can be easily drained and the strength of the original state can be maintained even after drainage.

Alternatively, the above-described filter media or filters are formed as spring-type or cylindrical filters to further prevent deformation of the cylindrical filter in the process of washing the filter by spraying high-pressure air or water. In other words, by further forming a spring-type restoring part on the outer circumferential surface of the cylindrical filter having a spiral cutout as described above, by spraying high-pressure air or water to increase the restoring force of the cylindrical filter in the process of washing the filter, It is also possible to further prevent damage caused by permanent deformation of the cylindrical filter due to air or water.

On the other hand, a cutout portion spirally cut in the longitudinal direction of the cylindrical body of the cylindrical filter is formed.

The cutout has a function of elastically deforming the outer shape of the cylindrical body when an external force due to the flow pressure of a fluid or an adhesive force between adjacent polymer filters acts on the cylindrical body, and elastically restoring the outer shape of the cylindrical body when the external force is removed. carry out

The elastic deformation of the cylindrical body causes bending or bending deformation with respect to the central axis in the direction of the external force.

In addition, the part receiving the external force undergoes eccentric deformation with respect to the central axis according to the direction of application of the external force. This elastic deformation action facilitates the floating of the coalesced oil components while moving between the surface of the cylinder and the space, and minimizes the adhesion of solids by brushing off the solids adhering to the surface of the cylinder. Falling to the bottom of the filter cylinder is made more smooth.

On the other hand, the above-mentioned floating filter medium, floating irregular granular filter medium, floating filter medium, hydrophobic foamed polymer filter medium, and high-speed hydrophobic foamed polymer filter medium may be a cone-shaped suspended polymer filter, and are formed as a hollow cone, thereby minimizing the weight compared to the volume surface area. .

If the size of the polymer filter is formed too large than the above size, the weight is greater than the specific gravity of water, so that it does not float in water and sinks, so that it cannot perform the function of separating sewage and removing solids. Conversely, if the size is too small, the surface area is small, so the sewage separation performance and solids removal performance are reduced.

In one embodiment, the filter includes branched polyether-polyester polyol, filler, silicone oil, fatty acid ester, acrylic copolymer, It can be protected with a coating agent containing zeolite powder and sunscreen.

Therefore, a coating agent having excellent adhesion, water resistance, gloss, abrasion resistance, and chemical resistance, which prevents damage from being easily damaged by external impact during filtering, is added in the ratio described above.

Because polyester polyol has excellent abrasion resistance, tear strength, flexibility, oil resistance, heat resistance, and elasticity, but has a problem of hydrolysis by water, 35 to 60 parts by weight of filler, silicone oil 0.1 to 2 parts by weight, 1 to 10 parts by weight of fatty acid ester, 0.1 to 3 parts by weight of copolymer acrylate, 1 to 5 parts by weight of zeolite powder, 0.1 to 3 parts by weight of sunscreen Include wealth.

In addition, the filter may be coated with a protective layer made of one of polycarbonate, ethylene-tetrafluoroethylene, ethylene vinyl acetate, aluminum foil, polyolefin, polyvinyl butyral, and silicone resin.

According to one embodiment, the hydrophobic expanded polypropylene media (EPP) or floating media or fiber media according to the present invention can easily impart porosity by preparing a polymer by an emulsion polymerization method, and also has chemical resistance to heavy metals. By grafting a thiol compound having bonding ability to the porous polymer at a relatively low temperature, high heavy metal removal efficiency can be achieved even with a small content.

In other words, it is functionalized with a thiol group and chemical adsorption occurs, so that the adsorption process is stable and has strong adsorption power. As a result, it is more efficient and economical than conventional adsorbents for removing heavy metals.

In addition, since the acrylic porous polymer is prepared through a simple method of emulsion polymerization, chemical functionalization is easy.

Through such a simple manufacturing process, it is possible to secure economic feasibility by facilitating mass production of products.

Alternatively, cadmium and the like may be easily removed through the reaction shown in Table 1 below.
