Description

Sedimentation and floatation apparatus for waste water treatment and treatment equipmentof of livestock and wastewater using it}

The present invention relates to a rapid flotation settling apparatus and a livestock manure and wastewater treatment facility using the same.

In the existing livestock farming house, the manure treatment method introduces a water treatment system in a large-scale farm with more than 5,000 heads, purifies it, and then discharges it, and it is common for farms of 2 to 4 thousand heads to be fertilized or self-discharged.

In general, in order to lower the BOD concentration during livestock manure treatment, it is common to perform liquid fertilization treatment after lowering the load by using an organic coagulant and an inorganic coagulant in raw water.

However, in this process, due to excessive use of coagulant and lack of organic carbon sources, it is difficult to treat nitric acid, and as the alkali concentration of water quality increases, low DO and odor are a problem.

In addition, in the fermentation process of corrosion, the color of recalcitrant decomposition is increased, which causes a complaint problem during discharge.

In addition, in the case of liquid fertilization or introducing a water treatment system for self-discharge, proper operation is often difficult due to the lack of dedicated personnel and the need for advanced treatment knowledge to meet government management standards.

In addition, in the case of the existing water treatment system, various chemical treatment agents and oxidizing agents are abused to meet specific regulations such as BOD, COD, T-N, and T-C, which causes another environmental pollution.

In addition, for the use of chemical treatment agents and oxidizing agents, the economic burden is very high on farmhouses, and illegal discharge is attempted to avoid them, and it is also placed in the blind spot as a non-point source of pollution.

Looking at the conventional technology for the treatment of livestock manure and waste water, "The method for purifying livestock manure using native microorganisms" (Korean Patent Publication No. 10-0336463, Patent Document 1) introduces a specific microorganism material into the manure and ferments. And manure purification treatment method to maintain aerobic conditions according to microbial properties.

However, the conventional technique using only microorganisms, such as Patent Document 1, has a problem that requires a large facility area because it takes a long processing time.

As a way to solve this problem, in the "liquid corrosion method, the method of removing nitrogen and phosphorus in advanced treatment of livestock wastewater or manure" (Korean Registered Patent Publication No. 10-0342667, Patent Document 2) exhalation reaction in a liquid corrosion bath There was an effort to remove nitrogen phosphorus simultaneously in a short time by continuously repeating the anaerobic reaction, inoculating a specific microorganism, and purging the entire treatment system in conjunction with a liquid corrosion bath.

However, the method of treating livestock manure using microorganisms, such as Patent Document 1 or Patent Document 2, has a slower processing speed compared to a physicochemical treatment method, and thus, "a method and apparatus for continuously removing phosphorus and suspended solids in waste water" Physical and chemical treatment methods such as (Korean Patent Registration No. 10-1081302, Patent Document 3) have recently become the mainstream.

Meanwhile, in a water treatment system, a sedimentation tank and a pressurized floatation tank are usually installed to remove contaminants from raw water.

The sedimentation tank is a device for separating and removing contaminants by using the difference in specific gravity between water and contaminants, but it is also settled by using gravity, but most of them form flocs to inject coagulants to accelerate the sedimentation rate and shorten the time.

In addition, the pressurized floatation tank is a device that removes light contaminants by floating them on the surface of the water using the specific gravity difference between the oil component and water, and the pressurized floatation tank is placed in a settling tank to remove pollutants remaining in the wastewater treated first in the precipitation tank. It is installed adjacent.

As such, both sedimentation and flotation processes and equipment are required for physical separation, and thus there is a problem in that the site is wasted and the cost required is increased.

As a technique to solve this problem, in the "water treatment tank having both the flotation and sedimentation function" (Korean Patent Publication No. 10-1587264, Patent Document 4), multiple cylinders are installed, and the raw water is inside the cylinder at the center of the well. Cases have been disclosed in which sedimentation and injury occur sequentially in the process of alternately moving up and down between adjacent cylinders after being supplied to.

In the case of Patent Document 4, compared to the case where the conventional sedimentation tank and floating tank are installed adjacently, there is an advantage that the facility area can be reduced.

However, the processing speed is inevitably slow in a manner in which sedimentation and flotation are sequentially performed.

In order to speed up the treatment, if the amount of water flowing in is increased, it cannot be precipitated or floated for a sufficient time, and floating material may be adsorbed on the sediment, or precipitated material may be adsorbed on the floating material. The water treatment proceeds while being separated from each other, which inevitably causes a load in the following process.

That is, in the case of patent document 4, there is a problem in that the treatment efficiency of sedimentation and suspended matter is lowered.

In addition, since the sedimentation is performed by a simple gravity method, the separation efficiency of the sediment decreases. In particular, there is a problem that the segregation efficiency of the suspended matter remarkably decreases because the suspended matter is collected at the bottom of the filter.

Hereinafter, a rapid floating precipitation apparatus of the present invention and a livestock manure and wastewater treatment facility using the same will be described in detail through the accompanying drawings.

Wastewater treatment facility using the rapid flotation settling apparatus of the present invention, as shown in Figure 7, the water collecting tank 100, the dehydrator 110, the flow control tank 120, the rapid flotation settling device 1, the ion decomposition sterilization reaction tank (130), intermittent aeration tank (140), first sedimentation tank (150), aerobic aeration tank (160) and second sedimentation tank (170).

The water collecting tank 100, which is a component of the present invention, has an empty cylinder shape as disclosed in a conventional water treatment device, and animal husbandry or wastewater is stored therein.

In addition, the water collection tank 100 is connected to the sediment discharge pipe 13 and the floating material discharge pipe 45, the first sedimentation tank 150 and the second sedimentation tank 170 of the rapid floating sedimentation apparatus 10 by pipes or conveyors, etc. It can be configured such that the discharged solids, sediments, suspended solids, etc. are supplied inside.

The dehydrator 110, which is a component of the present invention, is connected to the water collection tank 100 and a pipe provided with a pump or connected to a pipe with a built-in transfer screw to receive livestock manure or waste water stored in the water collection tank 100 and supply Dehydrate the received livestock manure or waste water.

The dehydrated cake separated through the dehydration process is processed separately, and the desalination liquid remaining after the dehydration treatment is stored in the flow control tank 120 through a pipe provided with a pump or a transfer screw.

The flow control tank 120, which is a component of the present invention, is dehydrated in the dehydrator 110 and temporarily stored so that the desorption liquid separated from the dehydration cake is temporarily stored and supplied to the rapid floating precipitation device 1 in a quantitative manner. Is composed of an empty tank, and a pump and piping are installed inside to supply a certain amount to the rapid flotation settling device 1 according to the operation of the pump.

The rapid floating sedimentation device 1 of the present invention is a main component of the present invention, the main body 10, the separation case 20, the raw water supply pipe 30, the floating material treatment tank 40, the separation device 50, sedimentation Consists of a case 60 and a precipitation guide device 70, the suspended matter and the precipitate are rapidly separated at the same time, and are made to oxidize the desorption liquid by ozone and radical ions supplied to the micro bubble ejector 32.

First, the main body 10 has a cylindrical structure having a flat bottom portion 11 and a side wall portion 12 formed to be vertically upward connected to the circumference of the bottom portion 11 as shown in FIGS. Achieve.

In addition, a sediment discharge pipe 13 through which sediment is discharged is connected to the lower side of the side wall part 12.

In addition, at a position spaced apart from the upper end of the side wall portion 12, a horizontal flow bottom portion 14 protruding outward in a horizontal direction is formed, and an external side wall portion 15 is formed at an end of the flow flow bottom portion 14 ) Is connected.

The outer side wall portion 15 is formed to be vertically upward while being connected to the overflow floor portion 14 to form a overflow space 15a between the side wall portions 12.

At this time, the outer side wall part 15 has an upper end higher than the upper end of the side wall part 12.

Accordingly, the raw water in the interior of the main body 10 rises to the top of the side wall portion 12 and then can flow into the overflow space 15a beyond the top of the side wall portion 12, and in this process, the side wall portion 12 The upper part acts as a filter.

On the other hand, as shown, the treatment water discharge pipe 16 is connected to the overflow floor 14, so that the suspended matter and sediment are separated and the remaining desorption liquid is discharged to be supplied to the ionolysis and disinfection reaction tank 130.

Separation case 20 takes the form of a tube penetrated up and down as shown in Figures 1 and 2, the outer circumferential surface is spaced apart from the inner circumferential surface of the side wall portion 12 of the main body 10, the main body 10 It is installed inside.

Referring to FIGS. 1 and 2, it can be seen that a frame not marked with a reference numeral interconnects the inner peripheral surface of the side wall portion 12 of the main body 10 and the separation case 20.

The lower end of the separation case 20 is spaced upward from the bottom 11 of the main body 10 as shown in FIG. 1.

Meanwhile, a filter material 21 is installed inside the separation case 20.

At this time, the inner space of the separation case 20 is divided into an upward space 22 above the filter medium 21 and a downward space 23 below the filter medium 21.

The filter medium 21 is installed to be fixed or detached inside the separation case 20 in various fixing methods such as being inserted into a case not shown.

The filter medium 21 can also exhibit a function of filtering the desorption liquid introduced into the separation case 20, and the separation device 50 by delaying the phenomenon that the desorption liquid introduced through the raw water supply pipe 30 moves downward by gravity It also plays a role in allowing the upward movement of suspended solids during operation.

The filter medium 21 for this purpose will form a porous structure. If the size of the pores is too small, a phenomenon in which the downward movement of the desorption liquid may not be well suppressed may occur, and the filter medium 21 is easily blocked, and thus the body 10 The inflow of tally liquid into the interior may not be achieved smoothly.

6 shows another example of the media 21 of the present invention.

In the drawing, the filter media 21 has an opening 21a formed at one side, an opening / closing door 21b for opening and closing the opening 21a, and a driving device 21c for operating the opening / closing door 21b. ) Is installed.

In the example of the drawing, for convenience of understanding, the opening / closing door 21b is hinged to one side of the filter medium 21, and the driving device 21c shows a motor connected to the hinge shaft as an example, and the opening / closing door 21b has an opening ( It will also be possible to configure a sliding installation in 21a).

At this time, the filter medium 21 may have a shielding structure that completely seals the interior of the separation case 20, or may have a network structure similar to a conventional filter medium.

The filter medium 21 in the case of taking the shielding structure does not function as a filtering bar, so it takes a network structure, and the void in this case is small in size because the opening / closing door 21b is opened.

In FIG. 6, a pump 121 is installed in the raw water supply pipe 30, and the driving device 21c and the pump 121 are connected to the control device 180, and the pump ( 121).

At this time, the upper motor 51 is also connected to the control device 180 to operate under the control of the control device 180.

That is, when the desorption liquid is supplied by the operation of the pump 121, the opening / closing door 21b blocks the opening 21a, and then, when the upper motor 180 operates, the desorption liquid is separated up and down.

While maintaining this state for a certain period of time, the control device 180 temporarily stops the operation of the pump 121, and when the opening / closing door 21b is opened, foreign matter (precipitating material or floating material) blocking the opening 21a is removed. The upward or downward movement through the open opening 21a can suppress the clogging of the filter medium 21.

That is, when the area of the individual pores is minimized by maximizing the number of pores while keeping the filter media 21 with a large skeleton area and having a small pore size, for example, 50% of the surface area, the upper portion of the filter media 21 is instantaneous. It is possible to induce a temporary residence phenomenon in a state in which the desorption liquid is supplied, and through this, the floating material can be smoothly moved upward by the operation of the separation device 50, and the opening / closing door 21b has an opening 21a. In the case of opening the precipitate material blocking the pores of the filter medium 21 can be moved to the lower space smoothly.

One side of the raw water supply pipe 30 is connected to the flow control tank 120, and the other side is eccentrically connected to the upper space 22 of the separation case 20.

Therefore, the desorption liquid stored in the flow control tank 120 is supplied to the upward space 22.

At this time, as described above, the piping is eccentrically connected to the outside rather than the center of the upward space 22, and the desorption liquid flowing into the upward space 22 causes spiral flow.

It is preferable that the plasma generator 31 and the micro bubble ejector 32 are connected to the raw water supply pipe 30.

The plasma generating device 31 is a device for generating ozone and radical ions by using high-frequency plasma by receiving air from the outside, and is known in various documents such as Patent No. 572514, so the description of its structure will be omitted.

Microbubble ejector 32 is also known, one side is connected to the plasma generating device 31, the other side is connected to the raw water supply pipe 30, ozone and radical ions discharged from the plasma generating device 31 It serves to supply the raw water supply pipe 30.

When ozone and radical ions are supplied to the desorption liquid using the plasma generator 31 and the micro bubble ejector 32, the oxidation reaction of organic substances in the desorption liquid is promoted.

In addition, organic substances, heavy metal complex ions, and polar organic molecules can separate the hydration layer.

At this time, the chlorine mixture may be supplied to the desorption liquid stored in the flow rate control tank 120 by piping the chlorine mixture supply tank (not shown) to the flow rate adjustment tank 120. In this case, ozone supplied through the micro bubble ejector 32 As the material is mixed in the raw water supply pipe 30, hypochlorite ions are generated by oxidation of chlorine ions, thereby increasing the solubility of oxygen in the wastewater.

The float treatment tank 40 connects the floor 41 and the ceiling 42 formed on the upper side of the floor 41 and the floor 41 and the ceiling 42 as shown in FIGS. 1 and 2. It consists of a wall (43).

At this time, the separation case 20 is fitted to the bottom 41, and the upper end of the separation case 20 is spaced apart from the ceiling 42.

Accordingly, a floating material retention space 44 is formed inside the floating material processing tank 40 to store floating materials that flow upward and move upward from the upward space 22 of the separation case 20.

On the other hand, one side of the wall 43 is connected to a floating material discharge pipe 45 through which the floating material stored in the floating material space 44 is discharged.

The float discharge pipe 45 is provided with a valve (not shown) as shown in the drawing, and a pump is installed on the pipeline to be configured to forcibly supply the float stored in the float retention space 44 to the water collection tank 100.

Separation device 50 is as shown in Figures 1, 2, 3, the upper motor 51 is installed on the upper portion of the floating treatment tank 40, and the upper portion is connected to the upper motor 51, The lower part is composed of an upper rotating shaft 52 and an upper blade 53 and a downward blade 54 installed on the upper rotating shaft 52 installed inside the separation case 20.

The upper rotation shaft 52 is installed at the lower end through the filter medium 21 as shown in FIG. 1, and rotates by the operation of the upper motor 51.

The upward wing 53 is connected to the upper rotation shaft 52 in the upward space 22 and is configured to move the desorption liquid supplied through the raw water supply pipe 30 upward, and the downward wing 54 is the downward space ( 23) is connected to the upper rotating shaft (52), and is made to accelerate downward movement of the tally liquid passing downward through the filter medium (21).

The shape of the upward wing 53 and the downward wing 54 may be made to take the shape of a cone as shown in FIG. 2, may be made of a screw shape as shown in FIG. 3, or be configured in various known shapes. It might be.

The configuration of the above-described separation device 50, when the upper rotation shaft 52 is rotated in one direction by the driving of the upper motor 51, the upward wing 53 moves the floating material 2 contained in the desorption liquid upward, , The downward wing 54 moves the desorption liquid downward, and forms a state in which the sediment 3 is contained in the desorption liquid.

At this time, the upper wing 53 does not drive completely in close contact with the inner circumferential surface of the separation case 20, but rather is driven away from the inner circumferential surface of the separation case 20, and floating materials such as scum are attached to the upper wing 53. It continues to move upward in a seated state, and the desorption liquid moves downward in the separation case 20 by gravity.

The settling case 60 is composed of a lower spacer plate 61, an upper spacer plate 62, and a settling guide tube 63, as shown in FIGS. 1 and 2.

The lower spacer plate 61 and the upper spacer plate 62 are both circumferentially fixed to the inner circumferential surface of the side wall 12 of the main body 10.

In addition, the lower spacer plate 61 is installed to be spaced apart above the bottom portion 11 of the body 10 to form a sediment storage space 61a between the bottom portion 11.

In addition, the upper spacer plate 62 is installed to be spaced apart from the upper side of the lower spacer plate 61, and is also spaced apart from the lower end of the separation case 20 to form a distribution space 62a between the separation case 20.

The sedimentation guide pipe 63 is connected to the lower spacer plate 61 and the upper portion is connected to the upper spacer plate 62, and takes a tubular shape penetrated up and down to form a precipitation guide space 63a therein. have.

At this time, the lower spacer plate 61 and the upper spacer plate 62 are respectively hole-hole-processed to be connected to the settling guide pipe 63, so that the settling guide space 63a is dispersed in the lower sediment storage space 61a and the upper part. It communicates with the space 62a.

At this time, the upper portion of the precipitation guide tube 63 is made to guide the induction of sediment and desorption liquid by taking a tapered shape of the upper and lower ganglia as shown.

Meanwhile, as illustrated in FIG. 5, the lower separation plate 61 and the upper separation plate 62 may be formed into a kind of network structure through which water can pass to maximize physical separation efficiency.

In this way, the separating liquid is introduced into the sedimentation guide pipe 63 by the operation of the sedimentation guide device 70, and the sediment material flows through the space between the sedimentation guide pipes 63 and the upper separating plate 61. ), It is possible to increase the physical separation efficiency by separating the suspended matter contained in the desorbing liquid that has not been separated from the separating device 50 while moving in the order of sediment.

At this time, the upper spacer plate 62 has a very small pore size to minimize the passage of sediment and desorption by the guide of the precipitation guide device 70, and the lower spacer plate 61 has a relatively large pore size to settle the guide. It is preferable to make the upward flow of the desorption liquid smoothly in a space other than the tube 63.

To this end, the lower spacer plate 61 is made of a metal mesh structure having a pore size of 3 to 5 mm, and the upper spacer plate 62 is preferably made of a hollow fiber membrane filter having a pore size of 0.001 to 0.1 μm.

As the upper spacer plate 62 is composed of a hollow fiber membrane filter, the precipitated material by the operation of the precipitation guide device 70 is relatively difficult to pass through the hollow fiber membrane filter and moves smoothly downward through the precipitation guide pipe 63, and conversely, precipitation In the region other than the guide tube 63, the flow of the upstream flow is naturally made smoothly, and floating substances that cannot be filtered are collected and filtered at the bottom of the upper separation plate 62.

At this time, in order to maximize the water treatment effect between the lower spacer plate 61 and the upper spacer plate 62, a filter material such as ocher ball may be filled between the lower spacer plate 61 and the upper spacer plate 62.

Since the ocher ball has a porous structure, the desorption liquid passing through the ocher ball is naturally purified.

At this time, the surface treatment of the pure sheet coating solution may be performed rather than filling the simple ocher ball.

Sunjit is a mineral from Russia's Karelia Shunga region, with silicate and fullerene as the main components, where fullerene means natural fullerene.

Fullerene contained in a large amount of pure paper is called a third carbon allotrope because it has a carbon allotrope such as graphite or diamond or a structural structure different from graphite or diamond.

Fullerenes have carbon rings in which carbon (C) atoms are arranged in a pentagonal or hexagonal shape, and these carbon rings are combined in a substantially spherical (spherical) shape to form a hollow.

After pulverizing such a pure paper, it is mixed with a dispersing solvent such as acetone or methyl alcohol, and then pulverized to prepare a pure resin dispersion. Metal oxide precursors, such as titanium tetraethoxide, and stabilizers, such as triethanolamine and diethanolamine, are added to stabilize the metal oxide precursor and the pure zet coating solution with the metal oxide coated on the surface of the susitite by the hydrophobic interaction force between the susitite. Prepared, it can be coated on the surface of the ocher ball.

As described above, the ocher fire coated with the pure zigzag coating solution is stably coated with a metal oxide precursor, thereby increasing the decomposition effect of organic substances by using the metal oxide.

The magnetic driving member 72b may also be made of the same permanent magnet, and an attractive force and a repulsive force act between the magnetic body 71b and the magnetic driving member 72b, and the magnetic force and the repulsive force are rotated by the rotation of the magnetic driving member 72b. The lower rotating shaft 71 is rotated by the action.
