Description

High concentration organic wastewater treatment system {The Waste disposal system}

The present invention relates to a high concentration organic wastewater treatment system, in particular, a high concentration organic organic wastewater can be treated through a separate additional device, as well as a high concentration of contaminants or sludge contained in the waste water in sequence through a series of devices It relates to a waste water treatment system.

As the current industry is advanced, the seriousness of environmental pollution has threatened human survival. Especially, the reduction of groundwater, rivers and seas as well as soil pollution as home sewage, factory wastewater, and livestock wastewater are becoming more serious. It is becoming a problem, and a lot of research and development and investment are being made to solve the problem.

In order to minimize the above water and soil pollution, it is desirable to reduce the emission of pollutants, but as the society becomes more advanced, the generation of various pollutants that adversely affect the water quality and the soil becomes inevitable, and from the pollutants Proper wastewater treatment measures, such as immediate removal of pollutants or harmless disposal, are essential.

The conventional method of treating the wastewater that is becoming a social problem as described above is a screening process for filtering relatively large contaminants contained in the wastewater into a screen having a hole having a uniform size, and sedimentation separation separating gravity-heavy contaminants by gravity. It is used to remove suspended substances and sediment contained in waste water by applying physical operation such as the first.Secondary flocculation and sedimentation or adsorption of suspended solids using various chemicals such as flocculant, adsorbent and disinfectant. It uses chemical unit processes, such as killing synthetic resin pathogens, and biological unit processes, such as decomposing non-settling biodegradable organics by the action of microorganisms, converting them into gases, or flocculating them with suspended solids. It is mainly configured to remove organic matter.

This process has the advantage of removing the sludge contained in the waste water to some extent, but because the process is not only complicated but requires a system that goes through many processes, it is not widely used or economically burdensome.

In addition, high concentration organic wastewater, such as livestock wastewater, has a limitation in that pollutant load falls even after biological treatment, and contains a substance that does not decompose well. It became.

Accordingly, an object of the present invention has been made in view of the above-mentioned conventional problems, to provide a high concentration organic wastewater treatment system that allows the high concentration of contaminants or sludge contained in the wastewater can be purified through a series of devices in turn. have.

It is another object of the present invention to provide a high concentration organic wastewater treatment system in which a livestock wastewater can be effectively purified by installing a separate additional device, that is, a livestock wastewater device that can separately treat livestock wastewater, in a high concentration organic wastewater system. .

When it is introduced into the interior through the secondary aeration tank is characterized in that the technical configuration consisting of a discharge tank for disinfecting and discharging the discharge to the outside.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a high concentration organic wastewater treatment system according to the present invention.

In the present invention, the anaerobic tank 100, the ozone partial oxidation apparatus 200, the primary aeration tank 400, the desorption tank 500, and the discharge tank 700 are basically used to treat high concentration organic wastewater as shown in FIG. Is mobilized.

Anaerobic tank 100 is a variety of contaminants and solids contained in the waste water is introduced into the state removed through the screen 110, and stays for a certain time, the ozone partial oxidation device 200 is introduced into the anaerobic tank (100) The waste water is pumped and circulated using the ozone contact pump 210 to reduce odor and perform biodegradation of hardly decomposable organic matter.

In the primary aeration tank 400, when wastewater passed through the anaerobic tank 100 flows through the flow adjustment tank 300, the carrier installed therein causes anaerobic oxidation, aerobic oxidation and denitrification to remove nitrogen components contained in the wastewater, and the desorption liquid. The separation tank 500 separates the sludge and water components contained in the waste water when the wastewater passed through the primary aeration tank 400 is transferred to the secondary aeration tank 600, and the sludge anaerobic tank 100 at the same time. The discharge tank 700 is configured to perform a role of disinfecting and discharging it to the outside when it is introduced into the interior through the secondary aeration tank 600.

In the present invention configured as described above, when various contaminants and solids contained in the waste water are introduced into the anaerobic tank 100 while being removed through the screen 110, the anaerobic tank 100 receives wastewater for a predetermined time (about 4 hours). Will stay.

At this time, if the ozone partial pump 200 is introduced into the ozone partial oxidizer 200 while the anaerobic tank 100 is stayed, the ozone partial oxidizer 200 generates ozone to reduce the odor contained in the waste water and is difficult to decompose. Biodegradation of organic matter.

When the wastewater passed through the anaerobic tank 100 enters the primary aeration tank 400 through the flow control tank 300, the carrier 410 installed therein causes anaerobic oxidation, aerobic oxidation, and denitrification to remove nitrogen from the wastewater. Remove Then, when the wastewater passing through the primary aeration tank 400 flows into the desorption liquid separation tank 500, the desorption liquid separation tank 500 separates the sludge and the water component contained in the waste water and the separated water component is the secondary aeration tank 600. The sludge is transferred to the anaerobic tank 100 again.

Wastewater introduced into the discharge tank 700 through the secondary aeration tank 600 is sterilized and purified and discharged to the outside.

On the other hand, if a separate livestock wastewater treatment device is installed in the high concentration organic wastewater treatment system as described above, the livestock wastewater can also be treated.

That is, as shown in FIG. 2, when livestock wastewater is introduced between the screen 110 and the anaerobic tank 100 via the screen 110, the treatment capacity is adjusted by the bypass 820, and when the treatment capacity is adjusted, the pump 810. Collecting tank 800 to transfer to the distribution tank 830, and when the livestock wastewater flows through the distribution tank 830, sludge settled to the bottom is transferred to the dehydrator 850 and the livestock wastewater separated from the sludge The sedimentation tank 840 to be transferred to the anaerobic tank 100 and, after the sludge is introduced into the interior through the distribution tank 830 dehydrator 850 for dewatering the sludge, after the livestock waste water through the screen 110 When introduced to the sump 800, the livestock wastewater treatment capacity is adjusted to the bypass 820, and when the treatment capacity is adjusted, the livestock waste water treatment capacity is controlled and transferred to the distribution tank 830 using the pump 810.

The livestock wastewater transferred to the distribution tank 830 is transferred to the anaerobic tank 100 so that the flow control tank 300, the primary aeration tank 400, the desorption liquid separation tank 500, the secondary aeration tank 600 and the discharge tank 700 are discharged. After passing through the sterilization and purification to be discharged to the outside, the sludge is introduced into the dehydrator 850 is dewatered.

As described above, according to the present invention, the high concentration pollutant or sludge contained in the waste water is purified through a series of devices in turn, as well as the livestock wastewater can be treated through a separate additional device. .
