Description

[0001] APPARATUS FOR SEPARATING WASTEWATER AND SUDDAGE [0002]

The present invention relates to an apparatus for separating wastewater and sludge, and more particularly, to an apparatus for separating wastewater and sludge from waste water and sludge, The present invention relates to a wastewater and a sludge separation apparatus, which can drain water only into a river, and sludge contained in water is solidified by a squeezing system to be discharged to a treatment plant, so that the efficiency of the operation is excellent and the cost is reduced.

As the industry develops, the severity of environmental pollution is rising. In particular, wastewater, factory wastewater, livestock wastewater discharged from homes, factories, or housing, etc., flows into groundwater and rivers, eventually polluting the sea.

If these wastewaters are treated and discharged without purification, they will cause sub-film phenomena such as rivers due to various organic matter, microorganisms, nitrogen (N) and phosphorus (P), and this will cause not only an aquatic ecosystem but also soil pollution And it threatens the right to live by destroying the food chain of living environment and ecosystem.

Of course, in order to reduce such damages, it is most desirable to reduce wastewater discharge fundamentally, but as the industry develops, it is inevitable to discharge various wastewater.

Typically, sewer pipes are buried in the basement, and wastewater discharged in daily life is all transferred to a certain place through the sewer pipe. In urban areas, which are populated areas, it is sometimes possible to find streams or rivers (hereinafter referred to as "river beds"). If these wastewaters are discharged without being treated separately, the river bed will be contaminated.

Particularly, in the recent development of the Cheonggyecheon development project, it is expected that the pollutants (hereinafter referred to as "sludge") in the wastewater will be removed from the wastewater, Separately filtered and relatively clean

It is urgent to develop a water treatment system capable of supplying the water (hereinafter referred to as "sewage") to the river bed so as to preserve the river bed in a clean state.

As a solution to the above-mentioned problem, Korean Patent No. 10-0610251 water treatment system and method have been proposed.

That is, the present invention relates to a water treatment system having a hollow fiber unit capable of effectively separating activated carbon from an aggregation process to maximize the adsorption capacity of activated carbon and effectively coping with an increase in treatment capacity, and a water treatment method using the system. An activated carbon treatment unit for producing activated carbon treated water by removing organic matter contained in the supernatant water by using activated carbon; And an activated carbon circulating unit circulating the activated carbon contained in the activated carbon treated water flowing into the microfiltration unit to the activated carbon treatment unit, An agitating tank for receiving raw water, and a flocculant for removing suspended solids And a sedimentation tank for precipitating sludge contained in the flocculation treatment water discharged from the flocculation agitating tank, wherein the activated carbon treatment section comprises an activated carbon agitating tank into which the supernatant water is introduced, Wherein the microfiltration unit comprises a storage tank for receiving activated carbon treated water and a hollow fiber unit in which a plurality of hollow fiber modules are unitized, Each of the hollow fiber modules is configured to include a hollow fiber membrane, a pair of head assemblies for fixing both ends of the hollow fiber membrane, and a support frame for supporting both the head assemblies at regular intervals.

However, the water treatment system constructed as described above is characterized in that it comprises an agglomeration agitator, an agglomerant supply pipe for supplying a flocculant for removing suspended matters to the agglomeration agitator, a sedimentation tank for precipitating the sludge contained in the agglomeration treatment water discharged from the agglomeration agitator, The size of the plane is large, so a lot of space is required, which is costly.

In addition, it is inevitable to use a large amount of water in the process of water resin, drainage, drainage, etc. in the industrial plant (steel, petrochemical plant, etc.). In this case, water treatment chemicals (Sludge, iron ore, sludge, sand, etc.) are contained in water and collected in a certain storage tank (water resin, artificial pond, storage tank, etc.) , A great deal of cost is incurred in treating this large amount of wastewater to waste water and there are many problems such as stopping the process in the condition that water can not be used during wastewater treatment.

In other words, most of the current treatment method is to prepare a reservoir to drain the water in the reservoir to be treated, and then to dry the reservoir for a certain period of time, .

This is because not only the process is cut off but also the inefficiency of the work causes a lot of cost. Especially, the wastewater treatment plant such as water resin or artificial pond is a region where harmful substances are contained in the human body and odor is generated, There is a risk of disaster.

1, when the main body 100 is floated on the storage tank 10 and a switch (not shown) is turned on, the underwater motor 160 and the underwater pump 131 are operated .

The rotating force of the submersible motor 160 is repeatedly rotated about 180 degrees in the fixed plate 170 and the sludge filtering device 200, which are integrally formed on the shaft.

The sludge deposited in the storage tank 10 is smoothly floated in the wastewater by the rotation force, and the sludge so floated is sucked by the suction hose 180 through the sieve 210, .

The wastewater and the sludge sent to the wastewater and sludge separating apparatus 300 are separated into wastewater and sludge by the swash plate 321 of the first separating tank 320 so that the sludge falls to the second separating tank 330, And is sent to the water catcher 340 through the catcher 323 through the plurality of small holes 322.

The residue in the sludge filtered by the primary separation tank 320 is sent to the collector 340 through the hole 322 of the secondary separation tank 320 and the sludge flows along the swash plate 321, And is sent to the transfer device 350 through the transfer device 341.

At this time, the wastewater sent to the water collecting unit 340 drains light water through the water discharge pipe 341 due to the specific gravity, and the residual sludge is deposited on the floor.

Then, the sludge which has been continuously immersed for a long time may be separated and cleaned by the water tank body 310 installed in multiple stages by the flange.

At this time, the bottom of the last tank body may be inclined, and a discharge valve may be provided at the bottom so that only fine sludge can be discharged separately.

On the other hand, as described above, the sludge sent to the transfer device 350 is sent to the squeezing device.

Then, in the squeezing apparatus 400, the motor is rotated, and the conveying screw 430 is rotated by the rotation of the motor. The sludge is advanced by the rotational force of the conveying screw, and at the same time, The water in the sludge is drained through the double-walled cylindrical net 420 by the process of being compressed by the high pressure by the unit 440 and the rotational force of the transfer screw.

Therefore, as described above, the solid-liquid separated sludge is collected and processed in a sludge transporting car (not shown).

While the present invention has been described with reference to the preferred embodiments and the accompanying drawings, it is to be understood that the invention may be practiced otherwise than as specifically described. Accordingly, the scope of the present invention is defined by the appended claims, and is not to be construed as limited to the specific embodiments described herein.
