The present invention relates to a sludge removal device of a cross-flow chemical sedimentation basin, and in particular, a water supply pipe having a plurality of injection nozzles is installed at the bottom of the sedimentation basin and sprayed from the spray nozzles of the water supply line, The present invention relates to a sludge removal apparatus of a sulfur type sedimentation basin which allows sedimented sludge to be discharged through a drainage chamber and an accumulation chamber.

In general, the chemical settling basin removes most of the large and heavily grown floc through the step of injection, mixing and floc formation through the mixed paper by sedimentation to reduce the burden on the rapid filtration paper, which is a subsequent filtration process. Has the function of

Therefore, the cross-flow sedimentation basin is the most effective sedimentation function for sedimentation of the turbidity contained in the influent raw water, and the buffer for absorbing the fluctuation of the turbidity according to the variation of the water quality and the quantity of water to keep the burden of the filter paper as possible as possible. The function and the sludge removal function to maintain the sedimentation function sufficiently and constantly at all times should be provided to ensure a normal sedimentation function.

The functions of the cross-flow sedimentation basin as described above have three functions such as sedimentation, buffering, and sludge elimination, which have an annual relationship with each other, but the most important function is the sludge removal function.

In other words, when the sludge is removed in a transverse sedimentation basin in a timely manner, the factor of shortening the residence time in the sedimentation basin or lowering the buffering function does not occur, thereby ensuring the required sedimentation and buffering function at all times. This enables more efficient and effective operation of the settling basin.

Conventional apparatus for the removal of such sludge is known mechanically sediment removal apparatus of various ways and structures that can be installed in the inner water of the sedimentation basin to automatically remove the sediment at a certain time.

However, in the installation of such a conventional automatic automatic sediment removal device, enormous facility costs are incurred, and a lot of difficulties arise in the normal maintenance of the device, and in case of a failure of the device, enormous loss of raw water is required because the influent in the sedimentation basin must be drained. This is followed.

In addition, when the mechanical deposit removal device is installed in the new sedimentation basin, the design and construction are relatively easy. However, in most of the existing sedimentation basins, there are many difficulties in the installation of the mechanical removal apparatus depending on the structure of the sedimentation basin. In the case of the sedimentation basin installed, there were problems and problems such as the inability to establish a mechanical sediment removal device according to the function and structural characteristics of the inclined plate.

Therefore, the main object of the present invention is to provide a sludge removal apparatus of a cross-flow sedimentation basin that does not have the above-mentioned difficulties and problems.

Another object of the present invention is to flow the sludge precipitated in the sedimentation basin by the water pressure of the feed water injected from the injection nozzle of the water supply pipe installed on the bottom of the cross-flow sedimentation basin and discharged through the drainage, without being bound to the new or existing sedimentation basin Various structures can be easily installed and installed in the sedimentation basin, thereby greatly increasing the efficiency of removing the required sediment without installing a separate mechanical removal device, and providing a sludge removal apparatus for the cross-flow sedimentation basin which is easy to maintain.

The present invention for achieving the above object is described in detail by the accompanying drawings as follows.

1 and 2 are a plan view and a longitudinal cross-sectional view showing the overall configuration of the cross-flow sedimentation basin is installed device, the third is the enlarged cross-sectional view of the main portion, as shown therein, the raw water inlet 1 and the supernatant outlet (2) are respectively provided at both ends, and inside both sides are disposed agglomerated paper 4 and a sedimentation basin 5, which are defined as flow process flow walls 3, and an intermediate part of the inclined bottom surface 5a of the sedimentation basin 5 side. In a cross flow sedimentation basin in which a sludge accumulation chamber 8 having a discharge pipe 7 is provided at one end of the drainage basin 6 installed in the drainage basin 6, a plurality of adverbs are provided on both sides of the drainage basin 6 of the slant bottom 5a. The nozzles 11 are not overlapped with each other toward the intermediate drainer 6 and the spraying direction of each of these injection nozzles 11 is directed to the drainer 6.

In the drawings, reference numerals 12 and 13 show the washing water supply pipes for supplying the washing water to the respective water supply pipes 10 and the valves installed in the branch pipes, respectively, and 14 shows the inclined plates installed inside the sedimentation basin 5. 9 shows an outflow trap installed above the outflow side end of the sedimentation basin 5.

Effects of the present invention sludge removal apparatus configured as described above are as follows.

When the sedimentation process of the sludge through the sedimentation basin (5) proceeds to accumulate more than a certain amount of sludge on the bottom surface (5a) to inhibit the normal sedimentation of the sludge, each valve 13 of the washing water supply pipe 12 of the present invention ) And at the same time opening the discharge pipe (7) installed in the sludge accumulation chamber (8), the washing water supplied to each water supply pipe (10) disposed on both sides of the settling basin (5a) through the open valve (13) Since the middle part of the sedimentation basin surface 5a is strongly sprayed toward the drainage basin 6 through the injection nozzles 11 provided in the water supply pipes 10, the sludge accumulated on the bottom surface 5a is strongly fluidized and In this way, the sludge collected in the sludge accumulation chamber 8 through the drainage tank 6 is discharged to the outside together with the water discharged through the discharge pipe 7 so that the sludge bottom surface 5a is discharged. Sludge accumulated in the It is possible to remove.

In addition, in the device of the present invention having the sludge removing effect as described above, the injection nozzles 11 of the water supply pipes 10 arranged in parallel adjacent in the longitudinal direction of the bottom surface 5a of the sedimentation basin 5 are shown in FIG. As shown, since the angles of the washing water sprayed by the drainer 6 are arranged so as not to overlap each other, the washing water sprayed from the respective spray nozzles 11 is evenly sprayed throughout the sedimentation basin surface 5a. As a result, the sludge removal efficiency can be further increased.

The present invention as described above, in removing the sludge accumulated on the bottom surface of the sedimentation basin, the water supply pipe having a plurality of injection nozzles are arranged at equal intervals on both sides of the drainage basin in the middle of the bottom surface of the sedimentation basin It is arranged to alternately toward the drainage, and each of the water supply pipe is configured to supply the washing water through the washing water supply pipe outside the sedimentation basin, can be easily installed in the sedimentation basins of various structures without regard to the existing or new sedimentation basin, It is easy to maintain and maintain the device easily by regularly removing the sludge accumulated on the bottom of the sedimentation basin by a simple method of operating the valve of the washing water supply pipe on the outer surface of the sedimentation basin without installing the mechanical removal device of the sedimentation basin. There is an effect that can greatly improve the precipitation efficiency.
