Description

High-speed settling pond using slope plate

The present invention relates to an inclined plate type high speed sedimentation basin which increases the sedimentation rate by reducing the depth of sedimentation by installing a plurality of inclined plates in the sedimentation basin, and allows each inclined plate to function as an independent sedimentation tank and at the same time without a separate lifting device. It is configured for maintenance.

In the physical or biochemical treatment process of water treatment facilities, such as water purification plants and sewage treatment plants, the treated water is stored for a certain time or flowed at a low flow rate to precipitate solid contaminants generated during the treatment process. The place where precipitation takes place is called sedimentation basin, and the fluid mixture consisting of solid contaminants is called sludge or sludge.

Sedimentation of solid contaminants is inevitably dependent on gravity, so the longer the contaminant moves, the deeper the depth of sedimentation, the longer it takes to settle, and the deeper the depth of sedimentation, the lower the sedimentation efficiency.

However, considering the relationship between sedimentation depth and sedimentation efficiency, if the depth of the sedimentation basin is kept too low, the treatment capacity is not only limited, but the disturbance effect of the sludge layer generated in the process of collecting and discharging sedimented sludge out of the sedimentation basin The problem that extends to the treated water of the will reduce the overall water purification efficiency.

In order to solve this problem, a plurality of inclined plates in the settling tank, such as the utility model registration No. 129346 "Slope plate sedimentation basin" of Figure 1 and Utility Model Registration No. 227423 "Inclined plate settling tank to maximize the settling area" of FIG. Sedimentation facilities have been developed and used to enable high-speed sedimentation by shortening and expanding the sedimentation depth and sedimentation area, respectively.

However, these conventional inclined plate sedimentation basin simply reduces the depth of sedimentation and expands the sedimentation area, and it cannot be said that each inclined plate functions as an independent sedimentation tank. There was an uncomfortable problem.

In particular, since each inclined plate or the settling space formed by each inclined plate is not completely isolated from the raw water before the external treatment, mutual interference may occur. For the replacement or repair of the inclined plate, the entire inclined plate may be separated from a separate equipment such as a crane. There have been many problems in terms of water purification efficiency as well as maintenance, such as lifting by using.

The present invention was devised in view of the above-mentioned problems, and both side ends are bent in a "c" shape, and the lower ends are bent backwards, and by installing a plurality of rectangular inclined plates closely installed inside the sedimentation basin, the upper discharge pipe is installed at the upper end. In addition, shortening the depth of sedimentation, each inclined inclined plate to form a sedimentation space isolated from the outside.

In addition, a sludge suction pipe reciprocating the bottom of the sedimentation basin was installed to discharge the sludge out of the sedimentation basin.

In particular, the side surface of the inclined plate is formed with a plurality of side raw water inlet holes, the center of which is parallel to the vertical line of the inclined plate and located on a straight line biased toward the front side of the inclined plate, so that the flow of raw water flowing into the inclined plate and the gliding flow of the sludge layer Interference between flows is minimized.

In addition, the inner discharge surface of the upper discharge pipe of the inclined plate is formed to be inclined so that the treated water can be discharged more smoothly.

The detailed configuration and operation principle of the present invention will be described with reference to the accompanying drawings.

First, as shown in FIG. 3, the basic structure of the present invention may be said to be a configuration in which a plurality of inclined plates 20 are installed in the sedimentation basin 10 and treated water discharge channels 30 are installed at both sides of the inclined plate 20. 4, the sludge suction pipe 41 reciprocated by the driving rope 18 is installed at the lower portion of the settling basin 10 to suck and discharge the sludge 93 deposited.

The inclined plate 20, which can be said to be a key element of the present invention, is a metal plate in a long direction in which both side ends and bottoms are bent, and both side ends are bent in a "c" shape to have side bends 21. To form, the lower end is bent backward to form the lower bent portion (25).

The side bent portion 21 not only forms the sedimentation space of the sludge 93 independently from the outside, but also increases the cross-sectional coefficient of the inclined plate 20, which is a plate, to effectively bend or twist. The lower bent portion 25 also causes the sludge 93 that slides along the inclined plate 20 to interfere with the upward flow of the raw water 91 introduced into the inclined plate 20 and the bottom of the inclined plate 20. In addition to preventing stagnation in the lateral bent portion 21 serves to increase the cross-sectional coefficient of the inclined plate 20.

Both ends of the inclined plate 20 penetrate the side bent portion 21, and an upper discharge pipe 23 having a plurality of treated water inflow holes 24 is provided on the upper surface thereof, and a plurality of side bent portions 21 are provided. The side raw water inlet hole 22 is formed, while the raw water 91 introduced through the lower side of the inclined plate 20 and the side raw water inlet hole 22 rises, solid contaminants are precipitated to become treated water 92, This treated water 92 is introduced through the treated water inlet 24 and discharged out of the inclined plate 20 along the upper discharge pipe 23.

Each of the inclined plates 20 is installed by mounting the lower portion of the side bent portion 21 and the exposed portion of the upper discharge pipe 23 on the lower support beam 12 and the upper support beam 11, respectively, as shown in FIGS. 4 and 6. 9 and 10, the inner spaces of the inclined plate 20 are separated from the outside by being in close contact with each other in a parallel state.

That is, as the front surface of the side bent portion 21 of the inclined plate 20 and the rear surface of the adjacent inclined plate 20 are in close contact with each other, the space between the front and rear inclined plates 20 is isolated from the outside, and as shown in FIGS. 4 and 9. Likewise, by attaching the order plate 26 to the front of the inclined plate 20 located at the fore, each of the inclined plates 20 can serve as an independent small settling tank.

Therefore, the raw water 91 containing the solid contaminants is introduced into the sedimentation basin 10 through the raw water inlet 13 below the sedimentation basin 10 as shown in FIG. 9, and then the inclined plate 20 as shown in FIG. 10. Inflow through the side raw water inlet hole 22 of the lower side and the inclined plate 20 to rise along the inclined plate 20, the solid contaminants precipitated in this process forms a sludge 93 layer to form the inclined plate 20 Sliding along, the treated water 92 is settled through the treated water inlet hole 24 formed in the upper discharge pipe 23, as in the enlarged portion of the circle of the same figure.

Raw water 91 is introduced into the side water inlet hole 22 is formed in a line, as in the enlarged portion of the garden of Figs. 10 and 12 to be biased toward the front side of the inclined plate 20, the reason is This is to prevent the flow of 91 and the flow of the sludge 93 layer sliding along the surface of the inclined plate 20 from causing interference with each other.
