1 and 2, a moving type floating separation pollutant removal device P and a pollutant removal method M using the same according to the present invention are provided with a pump 10 for pumping wastewater, A waste water tank 20 in which wastewater pumped by the waste water tank 20 is stored, a chemical admixture tank 30 for accumulating suspended solids in the wastewater, And a floating tank (40) provided with a bubble supplying unit (41) for supplying bubbles to separate the suspended material.

Float separation is one of the water treatment methods for separating light particles in water by using floating characteristics of micro-bubbles. Especially in the case of particles that are difficult to sink or where particles may sink and cause secondary contamination, float separation is one of the most appropriate alternatives. The floating separation process is widely used as an advanced solid-liquid separation process in order to effectively separate low specific gravity materials such as oil and fine suspended substances from the water. Dissolved air flotation (DAF) in drinking water was first attempted in Finland in the 1920s and was fully applied in Scandinavia, South Africa, and the United Kingdom in the 1960s.

Dissolved Air Flotation (DAF) is a method using the principle that minute bubbles generated are separated from the solids particles when the pressurized water saturated with air is momentarily depressurized.

The size of the bubbles generated at this time is about 30 to 100 mu m. Liquid separation of industrial wastewater and solids generated in water and wastewater treatment processes. The DAF process includes a rapid mixing tank for injecting coagulant into the raw water to induce a reaction, a slow mixing tank for maximizing flocs, a float tank (40) for floatation to the water surface after collision between the microbubbles and the flocs, And an air compressor for injecting air into the saturator. In general, a filter is installed at the rear end to form a single process. To dissolve the compressed air, the water is sent to the Saturator and the filtered water is used in the filter paper. According to the DAF technology development trend, the hydraulic load ratio did not exceed 2 ~ 3m / hr or 5m / hr in 1920, but it gradually increased to 20 ~ 25m / hr in 1996, hr. As the age, the shape of the DAF became closer to the square shape from the rectangle. This was achieved by the development of the hydraulic load ratio and the microbubble generation technique, and the more the microbubble layer, the higher the treatment efficiency.

The dissolved air flotation process was used in the mining industry in the US in the 1920s for the separation of minerals, and has been applied to the separation of paper in German paper industry. Its use in water treatment began in South Africa in the 1960s, and then spread to Europe, including Scandinavia. In the United States, it was first introduced and spread to Lenox in Massachusetts. Until 1990, the dissolved air-lift process was designed mainly based on the experience knowledge of the facility operators, and innovative research and development projects were mainly conducted in the UK. During this period, the overall understanding of the Dissolved Air Injection process has gradually expanded globally, and the need for a large-scale Dissolved Air In-Process facility, such as the Frankly water treatment plant (450,000 m3 / d scale) in the UK, has been raised. In addition, the need for optimal design parameters and operating conditions for dissolved air flotation has been raised. Since then, the researches on each part of the dissolved air flotation process have been carried out, and the CFD, CFD, the optimum design of the inflow nozzle and the pressurized tank for the microbubble and particle attachment process and the flow in the flotation tank (40) A new type of DAF system for the removal of combined flotation - filtration DAF, Cryptosporidium and Giardia, THMFP,

The characteristics of this process are inferior to sedimentation papers for the removal of algae and chromaticity, and studies on this process have been actively conducted mainly in Europe and USA. In the UK, sedimentation basins have been replaced by DAFs in order to overcome the closure of sand filters due to algae in the spring and summer of the Thames. In Germany, DAF is used in the case of raw water containing low turbidity and high concentration of Chlorophyll-a It was reported that the treatment used was significantly better than other treatment. In addition, the efficiency of DAF according to the species of birds was examined, and high treatment efficiency was also shown for diatoms and cyanobacteria. The results of the study using the dissolved air flotation method for Cryptosporidium and Giardia, the microorganisms causing waterborne diseases, showed that the dissolved air flotation method had higher treatment efficiency than the sedimentation.

Recent studies have been carried out on the practical application of the packaging process through the linkage between the flotation process and other processes. The combined process of flotation and lamella was developed by Purac and developed under the trademark LDAF. The combination of flotation process and sand filtration process was developed by Purac, Krofta and Ahlstrom, and was commercialized under the trademark Flofilter, Sandfloat and AhiFloat. Ozone Flotation and Flottazone were commercialized as a combination of ozone and flotation process. . In addition, studies are under way to improve the existing rectangular sedimentation tank to make float tank (40), and research to improve the existing sedimentation tank by combining high turbidity treatment, which is the advantage of sedimentation, . The research on the connection process with other advanced water treatment has also been carried out and it has been applied since 1993 at New Castle, New York.

In Korea, the first phase of the large-scale waterworks was completed in 2003, Various operational strategies such as direct filtration, DAF, and pre-settling according to the change of water source are required. Therefore, Korea Water Resources Corporation has been applying 'DAF' for 3 years to find efficient operation strategy, DAF water treatment technology standard, Water purification technology of advanced water purification technology '. In this study, the preconditioning conditions for optimum DAF process operation were derived by comparing and evaluating the characteristics of flocculation and floatation rate according to coagulant type, coagulation G value condition, and established DAF design guideline through water treatment analysis . The vegetable plaque removal rate was 96.8 ~ 98.8% in the DAF process at the transmission water treatment plant, and the ozone applicability in the water treatment process using DAF was evaluated

In Korea, although the dissolved air floating process has been applied variously as a floating separation method, there is a growing interest in electrolytic flooding in recent years. This is because the electrolytic flotation is more uniform than that of the dissolved air flotation process, and can produce small size bubbles, less bubble loss, and is relatively simple to operate.

Accordingly, the moving type floating separation pollutant removal apparatus P according to the present invention applies this floating separation method. First, the pump for pumping the wastewater (including the wastewater and the wastewater or the water containing various pollutants) The wastewater pumped through the pump 10 is introduced into the storage tank 20 and the water introduced into the storage tank 20 is moved to the chemical mixing tank 30, The wastewater is returned to the floating tank 40 to remove suspended matter (including contaminants such as oil and impurities mixed in water).

(First coagulant) is introduced into the second loading member 313, and a second coagulant that improves the cohesive force of the separated suspended material is introduced into the second loading member 313.

Generally, the drug may be variously selected by the user depending on the kind of the pollution source, and is preferably selectively used based on the conventional experimental data.

In addition, FLOC is a flocculent material that is difficult to sediment when suspended in water. Therefore, it is called floc, which is made up of large and heavy particles made by agglomerating particles by agglomeration and accelerating settling velocity. The better the coagulant is, the more effective it is to adsorb various substances.

The number of flocs formed in the chemical mixing tank 30 flows into the flotation tank 40.

The storage tank is further provided with a water level measuring member,
The level measuring member is composed of a housing Bf, a cover Bc covering the opening of the housing Bf and a link arm Au fixing the housing Bf to the storage tank 20 ,
The link arm Au includes a first link A1 provided in the storage tank 20 and a second link A2 connected to the first link A1 to adjust the length and angle, And a third link (A3) connected to the second link (A2) and coupled to the housing (Bf)
A hook H fixed to the housing supporting portion H4 by the shaft pin Hs is provided under the housing Bf in such a manner as to be elastically supported by the torsion coil spring H5,
The hook H is provided with first and second inclined stopping hooks H1 and H2 formed continuously,
A first latching portion Bf1 is formed on the upper side of the housing Bf and a second latching portion Bf2 is provided on the upper side of the housing Bf,
The cover Bc is provided with an upper first protrusion Bc1 and a lower second protrusion Bc2 coupled to the first or second latching portion Bf1 or Bf2,
When the cover Bc is engaged,
When the lower second projection Bc2 of the cover Bc is pushed toward the housing while the upper first projection Bc1 of the cover Bc extends over the upper inner first latching portion Bf1 of the housing Bf, The projection Bc2 passes the second inclined stopping hook H2 of the hook H to deform the torsion coil spring H5 so that the hook H is rotated upward about the axis pin Hs, The pushing force of the second protrusion is canceled after the pushing force Bc2 passes to the first inclined stopping hook H1 of the hook H so that the hook H is moved in the axial direction by the elastic force of the torsion coil spring H5, The second projection Bc2 and the first inclined stopping hook H1 are staggered to complete the engagement between the cover Bc and the housing Bf,
When the cover Bc is opened,
When the cover Bc is lifted as a whole, the second protrusion Bc2 and the first inclined stopping hook H1 are pressed so that the torsion coil spring H5 is deformed and the hook H is rotated The upper first projection Bc1 of the cover Bc is released from the state of being caught by the upper inner first latching portion Bf1 of the housing Bf and the first projection Bc1 of the cover Bc is released from the housing The second protrusion Bc2 of the cover Bc is located on the second inclined stopping hook H2 of the hook H and thus the second protrusion Bc2 of the torsion coil spring H5 The second projection Bc2 and the second inclined stopping hook H2 are interlocked with each other while being rotated about the axis pin Hs by elasticity,
The hook H is lifted to release the restraint of the second projection Bc2 by the second inclined stopping hook H2. The method according to claim 6,
