Device for disposing of things same as excretion, waste water, garbage and sewage

The present invention relates to a comprehensive wastewater treatment system for treating manure, livestock wastewater, sewage, and wastewater, and more particularly, to separate sediment solids and flotation solids by introducing a separated liquid filtered through the wastewater into a cyclone, and separating the separated liquid into treated water. It relates to a composite contaminant to be discharged to the.

In general, the removal of contaminants contained in manure, livestock waste water, sewage, and waste water is introduced into the screw press after inputting the contaminants into the inlet, applying various kinds of screens, and removing the coarse contaminants, and filtrate containing fine solids. Stay in the storage tank for a while.

In addition, while the filtrate retained in the storage tank is introduced into the cyclone by using a pump, the solid content of less than 10% of the filtrate falling below the cone by hitting the inner wall of the cylinder at the input pressure of the pump has a high water content. Again, the remaining 90% of the filtrate, which is added to the horizontal centrifuge and dehydrated, cannot rise to the center of the cyclone as a fine solid, so it rises and flows into the collecting reservoir.

In addition, the bottom of the coarse grain remover is installed so that the bottom surface is inclined, and the screw conveyor is inserted and mounted therein to remove only sand having a large particle size.

However, such a conventional contaminant remover does not respond to the sudden load of wastewater contaminants that are instantaneously input, and a large amount of sediment and suspended solids are accumulated in the treatment tank, occupies a lot of facility space, and consumes excessive power. Due to the increase in maintenance costs, there are many problems, such as a lot of restrictions on automatic operation.

In order to solve the above problems, Korean Patent Registration No. 343113 is published.

The Patent No. 343113 relates to a complex removal device and a method for treating a wastewater contaminant for treating wastewater contaminants, and more particularly, to configure the device so that a complete interlocking operation and a collective interlocking action can be performed. Injecting the contaminants removes the coarse contaminants contained in the wastewater contaminants with a ring screen rotor, inflows into the screw press, dehydrates them, and discharges them to the incinerator, and the fine solid filtrate passing through the screen of the ring screen rotor is the filtrate collection chute. It is introduced into the feed pipe of the conical centrifuge, which is linked to and causes the specific gravity separation using centrifugal force to continuously remove and dehydrate fine sediment, transfer it to the hopper tank, collect it, and transfer the separation liquid to the underground storage tank or the next treatment process by chute. Clean treatment plant, initial facility cost reduction and operation maintenance management effectively The present invention provides a method and apparatus for complex removal of wastewater contaminants to provide an automatic operation system.

In the Patent No. 343113, the fine solid filtrate passing through the screen of the ring screen rotor flows into the feed pipe of the conical centrifuge, and the fine grains are continuously removed and dehydrated by the difference in specific gravity using centrifugal force. The separated liquor is transported to the underground storage tank or to the next treatment process.

However, a large amount of fine solid filtrate flows directly into the conical centrifuge in the treatment process, and the phase of the material is separated according to the specific gravity by centrifugal force, thereby increasing the load of the conical centrifuge, thereby using a large centrifuge. The consumption of power increases, and there is a problem that the entire processing apparatus becomes large.

In addition, the floating solids mixed in the fine solid filtrate during the centrifugation process are included in the separation solution and then transferred to the next treatment process, so that the separation solution has to be purified through more processes.

The object of the present invention for solving the above problems is to filter out coarse filth from a contaminant such as manure, livestock wastewater, sewage, wastewater, etc. introduced from the outside, and input the separation liquid filtered coarse filth to the liquid abnormality separation means and floating solids and The sediment solids are separated first to reduce the load of the centrifuge, and the sediment solids are separated to the maximum in order to provide a comprehensive contaminant processor to simplify the purification process of the contaminants.

It looks at the operation and effects of the composite contaminant processor according to an embodiment of the present invention having the configuration as described above.

As shown, in the input of the contaminant in the contaminant processing unit 10 of the supply means (A) according to an embodiment of the present invention, the coarse contaminant of the contaminant is filtered on the rotary screen 14, the coarse contaminant is filtered separation liquid When the separation liquid valve 19 is opened, it is transferred to the transfer part 20 along the separation liquid pipe 17.

In addition, the desorption liquid generated while dewatering the coarse contaminant in the screw press 15 of the contaminant treatment unit 10 flows to the final discharge pipe 90 through the desorption liquid pipe 18 and is separated into the overplug pipe 16. Liquid is also flowed into the final discharge pipe (90).

At this time, the separation liquid flowing into the transfer unit 20 through the separation liquid pipe 17 flows into the processing tank 30 through the transfer pipe 25 by the operation of the transfer pump 21 and the opening of the transfer valve 24. do.

On the other hand, a preliminary transfer pump 22 in which a transfer valve 24 is installed is provided at the side of the transfer pump 21 so as to operate when the transfer pump 21 fails.

In addition, the separation liquid introduced into the treatment tank 30 flows in a tangential direction of the treatment tank 30 so as to follow the first separation passage 31 descending while rotating near the inner circumferential surface of the treatment tank 30. The liquid flows into the guide pipe 42 forming the second separation flow path 32 while descending to the lower portion of the treatment tank 30, and the precipitated solid mixed in the separated liquid sinks to the lower portion of the treatment tank 30 and precipitates. It is discharged to the separator tube 54.

In addition, the separating liquid along the second separation passage 32 formed of the guide tube 42 is the guide tube 42 through the through hole 38a of the flow plate 38 coupled to the inside of the guide tube 42. The flow along the guide pipe 42 of the separation liquid flows to the pressurized water inlet pipe 45 to the rising pressure of the pressurized water generated while flowing in the reverse direction in the flow plate 38, Is caused.

The separation liquid is formed between the guide tube 42 and the first space separation cylinder 35 by the second space separation cylinder 48 while passing through the through hole 38a of the flow plate 38. Pass through the separation passage (32).

That is, the separation liquid moves to the upper portion of the guide tube 42 and flows downward along the space formed between the second space separation cylinder 48 and the guide tube 42, and again the second space separation cylinder 48. And flows to the upper portion of the treatment tank 30 along the space formed between the first space separation cylinder 35.

At this time, the floating solids mixed in the separating liquid flows to the upper portion of the treatment tank 30 due to the difference in specific gravity and is discharged to the floating separation pipe 52, and the separated liquid from which the floating solids are separated is a third separation passage ( 33) to descend through the space formed between the upper portion of the second space separating cylinder 48 and the inlet of the discharge pipe line 50 is discharged to the discharge pipe line (50).

The rising pressure is added to the liquid and the floating solid is attached to the floating solid to more easily separate from the separating liquid, thereby contributing to flow to the top of the treatment tank 30.

In addition, the bubbles separated from the pressurized liquid are discharged to the atmosphere through the air vent 77 installed on the upper portion of the processing tank 30.

At this time, a part of the separation liquid discharged from the treatment tank 30 to the treatment water pipe 56 is circulated to the treatment tank 30 through the pressurizing means (C), so that the floating solids are more easily separated from the separation liquid, Only fine floating solids remain in the separation liquid flowing from the treated water pipe 56 to the final discharge pipe 90.

Then, the precipitated solids discharged from the lower portion of the treatment tank 30 to the sediment separator tube 54 and the floating solids discharged from the upper portion are introduced into the centrifuge 80.

At this time, the centrifuge 80 dehydrates the precipitated solids and flotation solids and discharges them to the dehydration cake and the desorption liquid.
