It is to prevent secondary pollution.

Description

Slow Pollution without Secondary Pollution {Pollution Free Slow Filtering}

The large floor area of buildings, households or simple tap water tanks (= water tanks), which are mostly made of reinforced plastics (= FRP), is suitable for slow filtration. FRP water tanks).

This technology, however, installs a slow filtration tank at the bottom of the tank to supply filtered and unfiltered general water to separate lines, resulting in double piping, thus reducing the practicality of the filtered water. However, due to the characteristics of slow filtration, there is a limit on the amount of purified water supplied, and the practical use is further reduced because it cannot meet the demand for large purified water.

The present invention is to arrange a filtration tank on the top of the tank structure to accommodate a large load, and to install a air compressor for the purpose of promoting slow filtration and pollution prevention by external air by arranging the reservoir tank to store the purified water in the lower part The objective is to provide a tank that can meet the demand for large amounts of water and expect perfect water purification.

The tank body (1) consists of a tank external copper (1A), a tank top plate (1B), a tank bottom plate (1C), a tank top entrance (1D), a tank bottom entrance (1E), and most of the foam polyurethane (= EPU) is made of reinforced plastic (= FRP).

The inner tank 2 is joined to the inside of the tank main body 1, and the plate-shaped footrest 2B with the opening 2C near the upper part of the inner tank 2 is joined.

Near the upper portion of the annular space between the outer copper 1A and the inner copper 2, the filter lower plate 3, which is an annular curved plate slightly convex downward, is firmly joined to the inner and outer copper 1,2.

In this way, the inside of the tank body (1) due to the inner copper (2) and the lower filter plate (3) and the settling tank (4) that is the inside of the inner copper (2)

Filtration tank (5) at the top of the filter tank lower plate (3) between the tank body (1) and the inner cavity (2) 3 parts, such as a reservoir (6) at the bottom of the filter tank lower plate (3) between the tank body (1) and the inner cavity (2) The filter tank 5 is divided into the upper filter air (5A) and the lower filter layer (5B).

Inside the sedimentation tank 4, a rectifier tube 8 connected to the raw water inlet pipe 7 passes through the opening 2C of the scaffold 2B and descends to the lower part of the sedimentation tank 4, and at the lower part of the filtration tank 5, The water pipe 9 is connected to the water flow pipe 10.

The water passage pipe 10 is also in communication with the reservoir 6.

The lower part of the settling tank 4 is connected to the outside and the settling tank discharge pipe 12 and the lower part of the reservoir 6 is connected to the outlet pipe 11 to supply purified water to the outside.

An air compressor 13 is installed on the upper portion of the tank top plate 1B, and the diffuser rod 15 is installed in the upper part of the settling tank 4 and is connected to the air compressor 13 by an air pipe 14.

The air vent 16 also serves as an overflow.

The operation of the present invention is as follows.

The lower part of the filtration tank 3 is convex in order to support the load of the filter medium layer 5B and the filtration atmospheric water 5A, and to collect the filtered water to the porous collection pipe 9 easily.

The porous collecting pipe 9 is provided at the lowermost part of the filter tank lower plate 3 where the filter tank lower plate 3 is most convex downward. Since the load applied to the lower plate of the filtration tank is transferred to the water tank lower plate (1C) and the ground via the outer copper (1A) and the inner copper (2), the outer copper (1A) and the inner copper (2) should be of sufficient thickness to support the load. The ground strength of the ground should also be sufficient.

The lower convex filter basin plate 3 can be subjected to much greater loads than the flat plate case.

The raw water introduced into the raw water inflow pipe (7) descends quietly along the rectifier (8), leaving the sediment at the bottom of the settling tank (4) and rises along the settling tank (4).

The sediment at the bottom of the settling tank sometimes discharges to the outside by opening the settling tank discharge pipe 12.

The raw water that has risen along the settling tank 4 is supplied with oxygen by the minute air bubbles emitted from the acid bar 15 after passing through the opening 2C of the scaffold 2B.

The air discharged from the diffuser 15 is of course supplied from the air compressor 13 via the air pipe 14.

Bacteria in the air are washed, absorbed, and dispersed in this bubble into the water, and when the air rises to the surface of the water, it becomes clean and then is discharged to the outside through the air outlet (= first-class pipe) 16.

The amount of air supplied from the air compressor 13 is designed to be greater than the amount of purified water supplied to the outside through the outlet pipe 11 of the reservoir so that air does not enter the outside of the air outlet.

The water supplied with oxygen is filtered in the filtration layer 5B via the filtration atmospheric water 5A state which is the upper part of the filtration tank 5.

The filtration layer 5B is filled with a thick filter in the lower part and a thin filter in the upper part by a well-known method.

Since filtration is slow filtration, most of the filtration is performed in the filtration membrane formed on the upper surface of the filtration layer 5B. Since the filtration membrane is an aerobic biomembrane, oxygen is required, and this oxygen is supplied by the bubbles supplied from the acidic rods 15.

The filtered water is collected in the porous collection pipe (9) and then stored in the reservoir (6) via the water supply pipe (10) and supplied to the external demand through the outflow pipe (11).

When there is a great demand for purified water, the purified water outflow lowers the water level of the reservoir 6 than the purified water, and the air of the upper portion of the tank flows into the upper portion of the reservoir 6 through the water passage pipe 10.

This air is clean air washed in water in the state of fine bubbles in the upper part of the settling tank 4, so there is no fear of secondary pollution.

External air flows into the air outlet 16 and never reaches the reservoir surface.

Bacteria and the like in the air washed and absorbed and dispersed in water cannot be contaminated because they are filtered out of the filtration tank 5.

Since the electricity required for the air compressor 13 is small, the operation may be continued, but it may be better to operate by detecting the drop of the reservoir level or the operation of the raw water supply pump.

The filtration membrane on the upper surface of the filtration layer 5B is clogged to some extent so that filtration is impossible, so cleaning is necessary. The cleaning is performed by a person stepping on the footrest 2B by opening the upper entrance 1D. If the filter layer is cut about 5 mm and the filter layer becomes too thin, replenishing the filter layer at once is the same as the other slow filtration tank.

The scaffold 2B is not only required for cleaning the filtration tank, but also prevents turbulence due to air bubbles generated from the acidic rods 15 from being transmitted to the bottom of the settling tank and inhibiting the settling action. Therefore, the opening of the footrest (2B) is good, but it is good to make the size of the person can enter and exit to be able to check the inside of the settling tank (4).

The footrest 2B also serves as a reinforcement frame for the compression buckling of the inner race 2.

The present invention, like other slow filtration, has very good filtration performance.

The removal of bacteria is certain, especially the removal of pathogens.

Since the filtration load is reduced by precipitating in the settling tank (4) before filtration, the filtration duration is long and if the water quality of raw water is excellent, it can be cleaned once every few years.

The air supplied through the air compressor not only supplies oxygen necessary for slow filtration but also prevents intrusion of contaminated external air and prevents secondary pollution by contacting only clean air washed on the water tank 6.

In view of the fact that the water purifier water purified by the excellent water purifier is excessively detected as a result of the secondary contamination of the water purifier reservoir, the present invention originally blocked the possibility of such secondary pollution.

Since the reservoir 6 is large, it can not only supply a large amount of purified water if necessary, but also maintain a proper slow filtration speed (about 3 m / day) by keeping the filtration load constant.

The present invention will be suitable for rural waterworks and schools. If activated carbon is used in the media, it can be widely used for urban buildings.
