Description

Dehydrating apparatus for treating wastewater suitable for separating sludge from wastewater}

The present invention relates to a treatment device for separating sludge (solid material, eg sediments, flakes) from wastewater generated in industrial or livestock farms, and in particular, sludge separation in wastewater to dewater sludge of solids separated from the wastewater. It relates to a wastewater treatment dehydrator suitable for.

Wastewater treatment, which occurs at various industrial sites or livestock farms, for example, pigs, barns, and poultry farms, is often used as a precipitation method using sedimentation basins. In such a sedimentation method, sediment (sludge) is inevitably occurring in the sedimentation basin and is treated separately.

However, in such a precipitation method, there is a problem in that the precipitate of the large solid particles is degraded in efficiency and manageability of the sedimentation basin.

Thus, in recent years, a separator is installed at the front of the sedimentation basin to filter out the sediment of a large particle, and it is not easy to treat the sediment of the solid separated therefrom. More specifically, in order to dry the solids separated from the wastewater and use them as incineration or organic fertilizers, the water must be dehydrated. Various dehydrators have been developed and used to dehydrate water contained in the sediments. However, the dehydration is not done efficiently.

The present invention has been made in consideration of the above circumstances, and an object thereof is to provide a dehydrator for wastewater treatment suitable for sludge separation, which can effectively dehydrate the water of the sediment by using a natural dripping method and a compression method.

The purpose of the present invention is achieved by providing a dehydrator for wastewater treatment occurring in industrial or livestock farms, such that the dewaterer overflows the overflow by pouring the wastewater through an inlet installed near the bottom. Temporary water tank is installed in a suitable position in the upper to flow by using; A first temporary catchment unit configured to receive waste water falling through the metal net under the separating means and to supply the stored waste water to the sedimentation basin through a drain hole installed near the bottom surface; Separation means for separating the solid sediment and water in the wastewater by using a metal mesh that is installed on one side of the temporary storage tank and has a suitable gradient extending downward in a certain length; And installed continuously at the end of the separating means, forcing the dewatered solid precipitate first through the separating means by a screwing method using a screw shaft, and allowing the dewatered wastewater to be supplied to the sedimentation basin through a second temporary collection tank. The dehydrated solid precipitate includes a dewatering means for discharging through the discharge port. Here, the wastewater is forced to be pumped to the temporary reservoir using a pump to flow the primary solid sediment and the waste water into the separation means by an overflow method. It is to be separated, and the first dewatered wastewater is dewatered completely using a second dewatering means of the compression method using a screw.

Next, embodiments of the present invention will be described in detail with reference to the drawings. 1 and 2 shows a wastewater treatment dehydrator structure suitable for sludge separation according to the present invention. Such a dehydrator mounts a cavity 20 having an enclosure shape on a frame 10 woven into a rectangular parallelepiped using roughly shaped steel, and installs wastewater for dewatering at an appropriate position on the upper side of the cavity 20 close to the floor. It is provided with a temporary reservoir 24 for allowing the water to flow through the inlet 22 to be temporarily stored.

And the waste water stored by using the upper one side edge of the temporary reservoir 24 is configured to overflow.

The metal mesh 26 is extended from the upper one side edge of the temporary reservoir 24, that is, the edge of which the waste water overflows, and extends a predetermined length downward with an appropriate gradient. The metal mesh 26 serves to separate the solid deposits contained in the wastewater while smoothly flowing down the wastewater flowing out from the temporary reservoir 24 by using a gradient surface to form the separating means 28. .

Solid sediment (sludge, shaft) separated using the metal mesh 26 of the separating means 28 slides down to the lower end of the separating means 28 and the waste water is disposed at the lower portion of the first de-seal means 20. Falling to the first temporary collection tank (30) provided is configured to flow through the outlet 32 to the sedimentation basin.

In addition, a dewatering means 34 is provided directly below the end of the separating means 28. The dewatering means 34 is provided with a width equal to the full length of the separating means 28 and a hopper 33 serving as an inflow guide for receiving solid precipitate falling from the separating means 28, and the separating means 28. The cylindrical tube body 36 has a length extending from the left end to the right end of the end of the tube and extends outward from the right end thereof, and has a discharge port 35 below the right end side. The drive shaft 38 is provided over the full length of the internal body, and the screw 40 is fixed to the drive shaft 38 at a fixed length. At this time, the screw 40 is not installed in the full length of the drive shaft 38, but is installed only a predetermined distance, that is, a position away from the outlet 35 by a predetermined distance, and the screw shaft is installed by the separate drive motor 42. The solid precipitate which is rotated at an appropriate speed and separated by the separating means 28 will be decompressed by a compression method.

In addition, the cylindrical tube 36 of the dewatering means 34 enters and exits from the inner circumferential wall of the cylindrical tube 36 to the central side of the cylindrical tube 36 at a position before reaching the outlet 35. It is provided with a discharge control means 44 that gives a load on the progress of the compressed product passed through) and controls the discharge speed. This discharge control means 44 can be used in a number of ways, as one embodiment in the present invention by using the length of the bolt as shown in Figure 3 to obtain the desired discharge control. Such emission control means has a great influence on the dehydration performance.

Moreover, the screw shaft 38 is provided with the stripping blade 46 which shakes off the solid precipitate which carried out dehydration. This stripping blade 46 is located directly above the outlet 35 to help discharge the precipitate.

In the main wall of the cylindrical pipe body 36 of the dewatering means 34, the metal mesh board 48 is installed from the main wall to the bottom side over a predetermined period in which the screw 40 is installed. ) Was discharged out of the cylindrical tube (36).

The compressed water squeezed out in this way is temporarily collected in the second temporary collection tank 50 installed in the lower portion of the cylindrical tube 36 to the sedimentation basin through an outlet 52 installed in one side of the second temporary collection tank 50. To be supplied.

The present invention is to separate the solid sediment and waste water in the waste water by using the separating means first, and the first separated sediment by the dehydration means using a screw method to dehydrate the solid precipitate completely.

In addition, the dehydration state of the solid precipitate is controlled by the discharge control means, and the dehydration is efficiently performed.

In addition, the sediment formed in the dehydration process is smoothly discharged by the stripping day.

As described above, an embodiment of the present invention has been described, but the present invention is not limited thereto and may be changed within the scope of the claims.
