Reference numeral 66 is a valve provided on the recovery pipe (64).

The operation and effects of the present invention and the apparatus of the present invention with such a configuration are as follows.

When a contaminant is introduced into the inlet 3 of the main body 2 by a powdered car or livestock wastewater, an optical sensor (not shown) operates to operate the contaminant screen 1 and the contaminant screw press 11.

As the screen 4 is rotated by the motor 6, the sprockets 7, 8, and the chain 9 of the screen of the contaminant 1, and the contaminant is introduced onto the rotated screen 4, a cigarette filter and milk The large sized contaminants such as packs and vinyls are dropped onto the screw 12 by the vanes of the screen 4 and the remaining treated water is stored in the lower primary tank 21.

Here, as the contaminants are introduced into the upper part of the screen 4, foreign substances such as vinyl or cloth pieces included in the contaminant may be caught between the wings of the screen 4, and the wiper screen 5 rotates to This foreign matter, which is caught between the wings is removed to fall to the screw (12).

In this way, when a large contaminant is supplied onto the screw 12, the screw 12 is rotated by the motor 14, the sprocket 15, 16, and the chain 17 of the concave screw press 11, and the contaminant is rotated. It is pressed while transferring upwards.

The desorption liquid generated from the compacted compact is dropped downward through the hole of the cylinder 13 and stored in the primary tank 21, and the compacted material compacted by the screw 12 is the complex transport belt conveyor through the outlet 18. Transported to the bed and discharged.

In this way, when the water level is in a proper state in the primary tank 21, it is supplied to the secondary tank 23 through the transfer pipe 22, and when the water level increases in the secondary tank 23, a sensor (not shown) Sensing and operating the pump 24 to supply the treated water cyclone (25).

As the cyclone 25 operates, a substance that is heavier than the fluid transported by the principle sinks downward, and a light substance floats, and foreign substances such as sand or gravel having a higher specific gravity than waste water sink and sink. Is transferred to the screw screw conveyor 31, foreign matters such as seeds of fruit having a specific gravity smaller than the waste water is overflowed to the separation pipe 41 through the upper pipe (26).

Here, foreign substances having a large specific gravity such as sand or gravel introduced into the lower pipe 27 of the cyclone 25 are transferred to the upper side of the casing 32 by the screw 33 of the screw screw conveyor 31. 33 is rotated by the driving of the motor 36, the sprockets 37, 38 and the chain 39 to compress the foreign matter while conveying the upper portion of the casing (32).

The foreign matter that has passed through the dehydration device 34 is completely detached and then transported to the sacrificial discharge belt conveyor through the discharge hole 35 and discharged, and the desorption liquid flows back into the secondary tank 23.

Meanwhile, as the treated water overflows through the upper pipe 26 of the cyclone 25, it is transferred to the lower side through the inflow space 43 of the separation pipe 41, and the introduced treated water is wastewater and seeds contained therein. Wastewater is introduced into the overflow tank 61 through the outlet space 44 of the separation pipe 41, and the seeds are caught on the filter plate 45 of the separation pipe 41 because the specific gravity of the back is made of foreign matter. The contaminant screw conveyor (51) is gathered under.

Seeds gathered under the contaminant screw conveyor 51 are transferred to the upper side by a screw 53, compressed and completely detached while passing through the dehydrating device 54, and then transported to the contaminant carrying belt conveyor.

The wastewater supplied to the overflow tank 61 is filtered by the partition 63, and foreign matters are discharged to the treated water storage tank through the drain pipe 65 when the state of the wastewater is above an appropriate level.

In this case, when the wastewater stored in the overflow tank 61 contains a foreign substance of an appropriate level or more, the valve 66 is opened to supply the wastewater from the overflow tank 61 to the secondary tank 23 to perform the above-described operation again. .

On the other hand, although not shown, the screen for the contaminant screen (1) and the screw press (11) is further provided with a washing device, respectively, the cleaning device of the screen of the contaminant screen (1) of the present invention, the processing apparatus of the contaminant of the present invention is the body ( 2) It cleans the inside and its parts, and the cleaning device of the confinement screw press 11 plays a role of always supplying water to the contaminants having different concentrations according to the winter season or the summer season so as to have an appropriate level of concentration.

Such a method for treating a contaminant of the present invention and the apparatus thereof, even if foreign matters of various sizes are mixed in the contaminant, can be discharged after being properly separated and compressed according to the size and specific gravity.

That is, the large size of contaminants are discharged primarily by the contaminant screen (1) and the contaminant screw press (11), and the large contaminants are discharged to the yarn screw conveyor (31) through the cyclone (25), the specific gravity is small The contaminants are discharged to the confinement screw conveyor 51 through the cyclone (25).

The wastewater from which the contaminants have been removed in this way can be drained according to the purified state, but it can be introduced again into the secondary tank 23 so that the above-described process can be repeated. I can make it.

According to the method and the apparatus for treating a contaminant according to the present invention as described above, when the contaminant is introduced, the contaminant having a relatively large size is first separated and discharged by the contaminant screen 1 and the contaminant screw press 11, and the cyclone ( 25) is separated and discharged a large specific gravity and a small specific gravity, and the waste water discharged as the contaminant is filtered through the overflow tank 61 and then drained, or the waste water in the overflow tank 61 again. Since the cyclone 25 is circulated and reprocessed, various impurities contained in the wastewater can be reliably removed step by step, thereby improving the reliability of the processing of the impurities.
