Detailed Description

The following is a detailed description of the structure of the present invention different from the prior art, and the structure substantially the same as the prior art can be implemented completely according to the prior art, which is not repeated herein. For the sake of more precise description, all the drawings are provided with a rectangular spatial coordinate system with a common orientation, so as to accurately describe the orientation consistency of the device and the parts in each drawing.

First embodiment

Referring to fig. 1, the housing 1 of the decentralized high-efficiency water treatment device is a 40-foot standard container with an open upper end, a flocculation tower 2 (see fig. 4), a sieve plate flocculation device 3, a water distribution plate 4 and a water outlet tank 6 which are omitted in the figure are arranged inside, and a sedimentation device 5 (see fig. 5) which is omitted in the figure is arranged in a space formed between the water distribution plate 4 and the water outlet tank 6 in the Y direction. A plurality of sludge discharge pipes 7 are arranged below the reaction zone, a plurality of sludge discharge pipes 8 are also arranged below the sedimentation zone, and a manhole 9 is arranged on the wall of the sedimentation device 5 below the Z direction of the shell 1.

Referring to fig. 2 and 3, the pipe orifice of the water inlet pipe 21 and the pipe orifice of the water outlet pipe 61 are located on the outer surface of the shell, and the pipe orifices of the sludge discharge pipe 7 and the sludge discharge pipe 8 are also located on the outer surface of the shell 1, so that the whole device is convenient to move, the

sludge discharge pipes

7 and 8 can be conveniently connected with a sludge discharge main pipe after being transported to an installation place, and flanges of the pipe orifices and manholes slightly protrude out of the outer surface of the shell 1 for convenience of installation and disassembly, but the moving transportation of the device is not influenced.

Referring to fig. 4, the arrangement of the

sludge discharge pipes

7 and 8 in the housing 1 and the installation position of the flocculation tower 2 can be seen, the water inlet pipe 21 as the whole distributed efficient water treatment device is also the water inlet pipe of the flocculation tower 2, and the pipe orifice flange of the water inlet pipe 21 is also located on the outer surface of the housing 1.

Referring to fig. 5 and 6, the position relationship between the flocculation tower 2, the screen plate flocculation device 3 in the reaction zone, the water outlet pipe 61 and the sludge discharge pipe 7 relative to the shell 1 can be seen.

Referring to fig. 7, raw water enters the flocculation tower 2 from the water inlet pipe 21, flows out of the flocculation tower 2, sequentially flows through the sieve plate flocculation device 3, the water distribution plate 4, the sedimentation device 5 and the water outlet tank 6, and then is output from the water outlet pipe 61. The above flow process can be illustrated by the open arrows in figure 7, where the flow in the sieve plate flocculation apparatus 3 runs in each cell with a cross circle to indicate negative flow to the Z-axis and a dotted circle to indicate positive flow to the Z-axis.

Referring to fig. 8, fig. 8 shows the structural features of the water distribution plate 4 of the present invention are as follows: the water distribution plate 4 is provided with a plurality of rectangular water passing holes 41 with the same shape and size, the coordinates of the rectangular holes 41 on the Z axis are the same, but in the X axis direction, from the right to the left in fig. 8, the distance between the adjacent water passing holes 41 is gradually reduced, namely the rectangular holes are arranged more and more densely, thus, after the water distribution plate is installed in the shell 1, referring back to fig. 7, when the water in the reaction zone flows into the water distribution zone from the outlet 31, the flow velocity is relatively fast at the outlet 31, the flow velocity is gradually reduced along the X direction, and the flow velocity is relatively slowest to the other end 32, thus the water supply to the sedimentation device 5 can be ensured to be uniformly distributed in the X direction. The principle that the flow is equal to the product of the flow velocity and the flow area is mainly used, the water through holes with relatively small flow areas are arranged at the positions with large flow velocities, and the water through holes with relatively large flow areas are arranged at the positions with small flow velocities. The side of the water distribution plate 4 facing the sedimentation device 5 is further provided with a baffle 42, when viewed from the Y direction, the baffle 42 covers the water through holes 41, the baffle 42 is longer than the water through holes 41 in the Z direction, a water through gap is arranged between the two in the Y direction, the baffle 42 has the function as described above, and the size of the water through gap is preferably equal to the area of the water through holes 41, which can be determined by the size of the water through gap. In this embodiment, the baffle 42 is fixed on the water distribution plate 4 as a part, but the water distribution plate 4 may also be a metal plate, and the water through hole 41 and the baffle 42 are directly formed by punching.

Second embodiment

Referring to fig. 9, the difference between this example and the previous example is that the housing 1 is a 20 feet standard container, because the size is smaller than the first example, it has the characteristic of relatively flexible assembling, disassembling and transporting for small load water treatment, because the small size of the housing 1 is adopted, the arrangement direction of the settling device 5 in this example is different from the first example, the overflow is along the X direction, therefore the overflow surface is small, and the water treatment flow is small.

Referring to fig. 10, a height-adjustable weir plate 62 is provided in the outlet tank 6, i.e., the weir plate 62 is adjustable in height in the Z-direction. Of course, the weir plate of the first example may also be adjustable.

Third embodiment

The difference between this embodiment and the previous two embodiments is that the outlet tank 6 is designed as an inner tank 63 and an outer tank 64, the inner tank 63 is inside the housing 1, the outer tank 64 is arranged outside the housing 1 and is adjacent to the inner tank 63, and the inner tank 63 and the outer tank 64 are in fluid communication. The outer case 64 is detachably provided with respect to the housing 1, and if the outer case 64 is not large in the X-direction, it may be fixedly provided in a state where it is not enough to affect the transportation.
