Description

A Processing Apparatus for Wastewater Treatment

The present invention relates to a treatment apparatus for recycling water pollutants (waste water) discharged from food waste recycling facilities to compost of animal feed or plants, and more specifically, to recycle the waste water discharged from food waste recycling facilities to the environment It is a low cost eco-friendly food waste wastewater recycling device that can drastically reduce the cost of pollution and discharge treatment, and it relates to a device that removes a certain amount of water contained in wastewater in order to work in low cost and space. .

As announced by the Ministry of Environment and the Korea Environmental Resources Corporation, Korea generates about 233,000 tons of waste annually, of which about 23% of food waste is produced. It is discharged by using a collection container or a dedicated bag, and the municipality collects it by using a food waste collection vehicle directly or by consignment, and the collected food waste is disposed of directly or in a consigned food waste treatment facility.

The food waste treatment facility should have an input facility, a sorting facility, a crushing facility, an odor removal facility, and a water pollutant (wastewater) treatment facility. Of these, the input facility relates to a treatment facility and its surrounding facilities. The facility around which the food waste is to be brought in should be easily and safely carried out by the food waste collection transport vehicle, and in particular, sufficient to prevent the input work from being delayed by the vehicle. The area should be secured, and the structure should be designed in consideration of the angle of repose, corrosion resistance, and abrasion resistance to prevent crosslinking of food waste, and the lower part of the structure is easy to transport food waste. It must be able to be transferred to the facility, and the water pollutants in the lower part can be transferred to the water pollutant storage tank or treatment facility by using natural drainage or power, and work is installed by installing facilities to prevent odor and supply cleaning water. Should be available upon completion or as necessary. Foreign substances such as vinyl, bones, and kitchen utensils contained in food waste vary depending on the collection method such as the use of a dedicated container or a dedicated bag, but contain about 5 to 10% of foreign substances, depending on how efficiently the foreign substances are removed. It greatly affects the quality of the products produced. The sorting facility is divided into the first sorting process to improve the quality by removing the impurities that were not removed in the first sorting process after the pre-treatment process and after the heating or fermentation process to improve the treatment efficiency and process. do.

 The shredding facility has a function of crushing food waste to have a particle size of a desired size, and is used to increase processing efficiency, and a food bag may be used to sack bags when the food waste is brought in a dedicated collection bag. . The smaller the mass of organic matter, the larger the surface area and the slower the treatment time due to the slower heating or microbial action.However, in the case of aerobic composting, the smaller the particles, the lower the porosity. If the particle size is adjusted to 20 ~ 50㎜ to be added to the fermenter, the fermentation period can be shortened.

In the process of collecting and transporting food waste, it is corrupted or fermented to generate nitrogen compounds such as ammonia, methyl sulfide, etc., and the odor resulting therein contaminates working conditions and the surrounding environment. Part. Major odor removal methods include washing, biological treatment, adsorption, and oxidation.

Lastly, water pollutants (wastewater) generated from food waste recycling facilities can be installed within the emission allowance by installing a prevention facility on their own, or they can be treated as influent sewage treatment facilities in consultation with local governments for stable and efficient treatment. .

1 is a method of feeding food waste by the conventional food waste device as described above, by putting the food waste collected by the food waste collection vehicle into the input hopper (A1) to separate foreign substances such as metallic substances and vinyl Step (A2), crushing step (A3) to break it, sterilization step (A4) to sterilize in a steam jacket of high temperature and high pressure by using a boiler, separation step (A5) for separating solids and waste water, separation Drying step (A6) to dry the solids, fermentation step (A7) to ferment the solids, mixing grains in an appropriate proportion to the fermented solids (A8), and finally molding and drying them into pellets (pellets) (A9) packaging and shipping step by step (A10). In some cases, a step (A6) of drying the separated solids and a step (A7) of fermenting the solids may be simultaneously performed.

In the conventional method, the sterilization step (A4) of the plurality of steps is a method of sterilizing at a high temperature and high pressure in the steam jacket, in which case using a diesel boiler, a gas boiler, or an electric boiler as an energy source. It is common. In addition, in the step (A6) of drying the separated solids, a high temperature hot air drying method is used, and light oil or electricity is used as the raw material.

On the other hand, the existing method for manufacturing compost from food waste includes a similar step to the above-described feed manufacturing method, specifically, the food waste collection and input to the hopper (A1), to separate foreign substances such as metallic materials and vinyl Step (A2), crushing step (A3) is the same, the three steps of food waste mixed with sawdust or rice husk as a moisture control agent to the composting step to ripen by microorganisms to complete the compost It is.

However, the food waste according to the conventional feed production method as described above is 70% of the total discharge is waste water. The wastewater was mixed with water and oil and could not be recycled. Conventional wastewater treatment methods are largely divided into three, the first is a method of dumping in the ocean, the second is a method of sewage treatment combined with sewage, and the third is a method of combining the two methods.

As described above, the methods of using sewage treatment facilities or dumping in the ocean are not completely purified to the sea or river in spite of a small cost (15,000 ~ 47,000 won / m ³ ) to purify the oil contained in the wastewater. It is dumped and causes environmental pollution.

The accommodation container 155 is preferably formed in a cylindrical shape in order to mix the waste water supported through the stirrer 120 smoothly, but the shape is not limited. In addition, the receiving container 155 should be sealed so that odors and harmful gases are generated in the process of treating wastewater and the supplied heat does not leak out.

The stirrer 120 provided in the accommodation container 155 is driven by an external motor (not shown), so that the waste water in the accommodation container 155 does not burn, so that heat can be evenly transferred to the center of the accommodation container and the waste water of the outer shell. The inside of the container is formed uniformly and rotated.

The oil pipe 125 provided in the first receptor 10 is installed while rotating in a spiral tightly downward from the middle of the first receptor. The inlet of the oil pipe 125 is supplied with the heated oil from the oil heater 130 to be described later, while passing through the oil pipe 125 formed in a spiral tightly inside the receiving container 155, the supplied oil is a container ( Heat is supplied to the wastewater contained in 155). The oil supplied with heat to the wastewater of the receiving container 155 passes through the outlet of the oil pipe 125 and enters the oil heater 130 to be heated again. The container 155 is completely sealed and supplies all the heat of the oil passing through the oil pipe 125 in the container 155 to the wastewater. Preferably, the inlet of the oil pipe 125 is installed at the stop of the receiving container 155, which is to reduce the total amount of the waste water to less than half even if water in the waste water is evaporated by the oil passing through the oil pipe 125. Because it is inefficient.

As the water in the wastewater evaporates, the wastewater becomes more concentrated and requires more heat to evaporate the water. On the other hand, the temperature of the oil supplied from the oil heater 130 is limited to completely evaporate the water in the waste water, usually around 300 ℃, the second receptor after evaporating the water until the amount of waste water is about 50% To remove a certain amount of water or to a wastewater treatment device (see FIGS. 6a and 6b) to completely evaporate the water in the wastewater.

Compression valve 145 provided in the first receptor is bound to the end of the steam discharge pipe 140 to compress the water vapor generated during the waste water treatment at high temperature and high pressure, when the generated water vapor is above a certain pressure , Discharged automatically. The compression valve is preferably driven when the pressure of 5.0kg (70psi). The water vapor discharged from the above configuration may be supplied to a second receptor connected afterwards at about 150 ° C. to supply heat to the wastewater supported on the second receptor.

The waste water quantity detection unit 150 provided in the first receptor detects the amount of the waste water loaded thereon when the amount of the waste water is reduced to about 50% of the amount of the receiving container 155. When the amount of wastewater is sensed by the wastewater detection unit, the operation of the oil pump 135 is stopped, and the wastewater having reduced water through the wastewater discharge unit 115 is discharged to the second receptor.

The window 160 of the first receptor 10 is formed of glass or transparent plastic so that the inside of the receiving container 155 is sealed, and is provided at one side of the receiving container 155.

One side of the first receptor is further provided with a waste oil suction pipe 165 and a waste oil suction pump 170 for discharging the oil component collected in the upper layer of the waste water.

As the oil used in the first receptor, it is preferable to use an oil having a high boiling point so as to effectively supply a large amount of heat to the wastewater contained in the accommodation container 155.

The first receptor may be executed alone or in combination with the second and third receptors described below.

3 is a detailed view of the second receptor of the present invention, and FIG. 4 is a detailed view of the third receptor of the present invention.

Steam discharge unit 235 for discharging the water changed by cooling the water at the same time to the receiver, agitator 240 for mixing the waste water to evenly transfer the heat supplied from the steam to the whole waste water, generated in the heated waste water felled It consists of a steam discharge pipe 245 for discharging the steam to the third receptor and a window 255 for viewing the inside of the sealed container 250 is sealed.

The accommodation containers 250 and 345 of the second receptor 20 and the third receptor 30 are preferably formed in a cylindrical shape to mix the wastewater supported through the stirrers 240 and 340. It is not intended to be limiting. In addition, since the accommodation containers generate odors and harmful gases during the treatment of wastewater, the receiving containers 250 and 345 are sealed during the wastewater treatment to prevent odors and gases from leaking out.

The agitators 240 and 340 provided in the second receptor 20 and the third receptor 30 are driven by a motor (not shown) and are treated with waste water contained in the accommodation containers 250 and 345. The heat supplied at the time can be evenly transferred to the waste water, and the waste water is prevented from sticking inside the accommodation containers 250 and 345.

The second receptor 20 and the third receptor 30 support and heat the wastewater generated in the conventional food waste treatment apparatus, and the steam pipes 230 and 330 are the second receptor 20 and the third receptor. It is evenly installed in the entire spiral portion of the receiving vessel (250) (345) of (30).

The steam moving pipes 230 and 330 provided in the second receptor 20 and the third receptor 30 are provided in the accommodation containers 250 and 345 so that the water vapor inflows 225 and 325 are provided. Heat is supplied to the wastewater supported by the container until it flows into the water vapor discharge part 235 and the water discharge part 335.

The amount of wastewater treatment of the second receptor 20 depends on the first receptor. When the oil pipe 125 of the first receptor 10 is installed from the middle to the lower end of the accommodation container 155, and the amount of the waste water reaches the inlet of the oil pipe 125, the waste water quantity detecting unit 150 is detected. The work of the first receptor is stopped and the wastewater is transferred to the second receptor.

As a result of the experiment, the throughput of the second receptor according to the work of the first receptor 10 was reduced by about 20-30% from the amount of wastewater first introduced.

The windows 255 and 350 formed in the second receptor 20 and the third receptor 30 are formed of glass or transparent plastic so that the interior of the sealed containers 250 and 345 can be seen. It is provided on one side of the accommodation containers (250, 345).

As described above, the water vapor discharged from the first receptor 10 is steam of high temperature and high pressure discharged through the compression valve 145. The high temperature and high pressure steam is supplied to the second receptor through the water vapor inlet 225 of the second receptor 20 to supply heat to the wastewater supported by the second receptor, and is supplied to the steam pipe 230. Some of the water vapor changes to water due to heat loss in the process, is supported in the water tank 40 attached to the water vapor discharge unit 235 formed at the end of the steam pipe (230), the remaining water vapor except for the part changed to water again It is transferred to the steam inlet 325 of the third receptor. The water vapor passing through the steam transfer pipe 330 of the third receptor is deprived of most of the heat to heat the wastewater loaded on the third receptor, so that the water vapor turns into water, and the water is connected to the water outlet 335. Flows into.

The oil component contained in the remaining waste water after evaporating the water contained in the inside of the first receptor 10 is collected in the upper layer of the waste water due to the density difference, and after the treatment is completed, the water contained in the waste water is completely evaporated to be recycled. When the oil component is excessively contained, to compensate for the disadvantages that are not suitable for livestock feed and compost, the oil component collected in the upper part is discharged as described above. The oil component collected in the upper portion of the wastewater is discharged through the waste oil suction pipe 165 and the waste oil suction pump 170, and the wastewater discharged from the oil component is discharged through the legendary wastewater discharge unit 115 and is discharged through the wastewater treatment device. Will be processed.

5 is an external perspective view showing the configuration of the pretreatment apparatus for wastewater treatment of the present invention.

Referring to FIG. 5, the treatment process of the present invention will be described in detail. The pretreatment apparatus for wastewater treatment includes a first receptor 10, a second receptor 20, a third receptor 30, and a bucket 40.

The third receptor carries wastewater generated through the process of sorting, crushing, feeding, and composting, which is a conventional food waste treatment procedure. The supported wastewater is primarily heated by water vapor generated from the second receptor and water vapor generated in the first receptor and passed through the second receptor, and rotates the stirrer 340 to mix the wastewater. At this time, the steam for heating the waste water is converted into water by dissipating heat, the water is changed through the water discharge portion 335, the first heated waste water is discharged through the waste water discharge portion 315 first It is transported to the container, in which the wastewater transfer pump 320 is quickly transferred to reduce heat loss.

The first receptor supports the wastewater heated primarily from the third receptor, and the supported wastewater is heated by the oil heated by the oil heater 130 and heated by the stirrer 120 at the same time. At this time, since the boiling point of the oil is higher than the boiling point of the water, it is possible to heat the supported wastewater at a high temperature. The high temperature oil heated by the oil heater 130 uses an oil pump 135 to minimize heat loss and quickly transfer the oil. Water vapor generated from the waste water treated as described above is compressed to high pressure by the compression valve 145 and discharged when a constant pressure (5 kg (70 psi)) is reached. At this time, since the steam is compressed to a high pressure is a high temperature of 100 ℃ or more, the generated water vapor is transferred to the second receptor to heat the waste water supported on the second receptor.

When the water in the wastewater evaporates due to the heat of the oil and reaches the inlet of the oil pipe 125 in the amount of the wastewater, the oil pump 135 sensed by the wastewater detection unit 150 provided at one side of the receiving container 155 and transferring the oil. Stop the heating of the supported wastewater by stopping the operation of), and discharge the oil components collected in the upper layer of the wastewater through the waste oil suction pipe 165 and the waste oil suction pump 170, the wastewater is wastewater discharge unit 115 It is transferred to the second receptor through the remaining water in the waste water process is processed.

The second receptor carries the waste water heated secondarily in the first receptor. The supported wastewater is heated secondly through high temperature and high pressure steam supplied from the first receptor and mixed by a stirrer. The steam generated in the process is supplied to the third receptor through the steam discharge pipe 245, the water vapor supplied from the first receptor passes through the second receptor to release heat and discharge the changed water, in the second receptor The waste water having reduced water is discharged through the waste water discharge unit 215 after the treatment is completed to be recycled or transferred to the waste water treatment apparatus (see FIGS. 6A and 6B).
