Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to the structure of a water purification treatment device.

(b) Conventional technology Conventionally, water purification treatment has been carried out by, for example, configuring an oil and fat separation device and a filtration device in communication, and the oil and fat separation tank has a waste water inlet facing upward and a conical umbrella above it. The oil and fat that floats to the top of the wastewater discharged from the spout are separated from the water that falls, and only the oil and fat is separated to a certain extent while being captured in a conical umbrella body. The sedimentation layer, which was formed in a vertically communicating manner with an inclined partition plate, was used to purify sewage while separating heavy mud, etc., into the lower part, and water, etc., into the upper part.

(c) Problems to be solved by the invention However, in water purification treatment with this structure, the oil separation tank has a similar specific gravity to that of water, so it is difficult to separate the oil from the water. Although mud and the like having different specific gravity can be easily settled, small pieces of dirt and the like cannot be completely settled downward and are discharged while being mixed in the treated water.

(d) Means for solving the problem In this invention, the water inlet of the sewage water injection pipe is arranged in the center so as to face upward, and a substantially conical oil and fat separating umbrella is arranged above it. In a water purification device in which a filtration device 2 having a sediment layer on the side of the device is connected to each other, sloped partition plates are mutually extended inward from the ceiling and bottom of the filtration device. , each partition plate has openings at the top and bottom to form a sediment layer that has a substantially meandering shape when viewed from the side, and a cleaning plate with an uneven surface is attached to the partition plate so that it can be pulled out. It is intended to provide a processing device structure.

(e) Effect In this invention, in the oil and fat separator, oil in the wastewater discharged from the water inlet is separated above the water inlet and moisture is separated below the water inlet due to the difference in specific gravity. Yes, the oil separated above is
The oil and fat separation umbrella located above also accumulates,
The water in the lower part overflows from the separator and flows into the filtration device.

Then, in the filtration device, the sewage from the oil and fat separator is retained in a sedimentation layer that has a generally meandering shape when viewed from the side, and mud, etc., which has a higher specific gravity than water, is settled in the lower part of the sedimentation layer, and the sewage is purified. It is.

At that time, by pressing the floating sewage from above through the plurality of slanted partition plates of the sedimentation layer, the settling action of dirt, etc. in the sewage is promoted, and the particles float to the surface of the cleaning plates of the partition plates. When sewage comes into contact with the cleaning plate, the uneven surface of the cleaning plate captures oil, dirt, etc. that are difficult to separate from the sewage.Furthermore, after the work is finished, the cleaning plate is pulled out from the partition plate and the cleaning plate is removed. This is for cleaning and replacement.

(f) Effects Therefore, according to the present invention, water purification can be effectively performed and wastewater treatment can be easily performed by the capture action of the cleaning plate to remove oil or minute dust mixed in wastewater. By making the cleaning plate removable, it can be easily cleaned and replaced, thereby improving work efficiency.

Furthermore, a sedimentation layer 9 is provided in the filtration device 2, and the sedimentation layer 9 is used to perform sedimentation treatment of mud and the like in the sewage.The detailed structure thereof is as follows.

That is, the sediment layer 9 is formed on the ceiling 2 of the filtration device 2
-1 and the bottom part 2-2, sloped partition plates 10 are mutually extended inwardly, and each partition plate 1
Upper and lower openings 9 - 1 and 9 - 2 are provided at the upper and lower tip portions, and are configured in a substantially meandering shape when viewed from the side.

Note that a is a communication path formed within the precipitate layer 9.

The sedimentation layer 9 having such a structure allows mud, etc. to settle in the vicinity of the lower opening 9-2 of the partition plate 10, and also allows rising sewage to flow through the upper opening 9-1 to each partition plate 1.
By communicating with 0, sewage is purified.

Further, the bottom part 2-2 of the filter device 2 is formed into a number of chevron shapes, and the partition plate 10 is extended from the top part 11-1 of the chevron-shaped part 11, and the troughs of the chevron-shaped part 11 are provided. Precipitate accumulates in 11-2.
