Abstract

PURPOSE: Provided is a purified water draw system using sand filter for reusing sewage and wastewater after purifying it. CONSTITUTION: The system comprises a purified water storage tank, a plurality of supporting bars(2) vertically installed at regular intervals at the bottom of the tank, a plurality of water catching blocks(4) installed on the top of the supporting bars(2), a plurality of strainers(5) attached on the water catching blocks(4), a coarse gravel layer installed on the strainers(5), a fine gravel layer on the coarse gravel layer and a sand filter layer on the fine gravel layer, a water inlet(9) provided at one side of the tank, a water outlet(10) installed at the opposite side of the tank, a water draw pipe(3) installed at a lower portion of the tank on the same side with the water outlet(10), and a back washing pipe(4) installed at a lower portion of the tank on same side with the water inlet(9).

Description

Sewage water intake unit {a water sand filter purifier draw system}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heavy water intake apparatus, and more particularly, to collect purified water from waste water and domestic sewage and use it as a heavy water.

Considering the current situation of purifying wastewater and domestic sewage and discharging them into rivers, and considering the environmental degradation caused by the development of water sources and the depletion of water sources, it is desirable to recycle the purified water of waste water and domestic sewage, Most of them are discharged because they are not properly made and some are used for agricultural water, but there is no water intake facility.

However, due to the indiscriminate groundwater development of dam construction that puts enormous budget, the groundwater is gradually being exhausted, and the wastewater is being discharged by purifying sewage, but now it is desirable to recycle such water.

In view of the above, the present invention proposes a heavy water intake device that can be utilized at low cost without damaging the natural environment by providing a facility to supplement and utilize the existing sewage-treated water facilities without depending on water supply or ground water. I would like to.

In consideration of the above-mentioned matters, one embodiment of the present invention will be described below with reference to the accompanying drawings.

1 is a configuration of the water intake apparatus of the present invention.

2 is a cross-sectional view of the filter medium in the water intake tank, which forms a support pillar ② at a predetermined height at the bottom of the outer wall body, installs a collecting block ④ on the upper portion thereof, attaches a strainer ⑤ to the collecting block ④, and has a thick filter on it. ⑥ and thin filter ⑦ filtered ⑧ in order to form inlet ⑨ toward the sewage treatment plant outlet, install the outlet ⑩ on the opposite side, form the intake pipe ③ on the lower side and install the backwash pipe 있도록 to backwash .

In one embodiment of the present invention configured as described above, when raw water flows into the device, it passes through the filter yarn ⑧, passes through the fine filter ⑦ and passes through the coarse filter ⑥ and strainer ⑤, further purifying and discharged from the sewage treatment plant. When the water turns into clear and clean water, it is supplied to the customer by using the intake pipe ③.

On the other hand, if foreign matters such as sludge accumulate in the filter ⑧ thin filter ⑦ thick coarse ⑥, close the intake pipe ③ and backwash with the back-washing tube⑫, and the foreign substances such as sludge are discharged through the discharge port.

As described above, the effect of the present invention is characterized by automatically filtering the purified water of the wastewater once more by the flow of water.

Operation according to the present invention is a useful invention that is capable of unmanned operation, inexpensive equipment costs, maintenance and maintenance costs, and almost no failure rate.

Claims (1)

It is a structure that can install the support pillar at the bottom of the intake device, install the collection block and strainer, fill the filter yarn filter sand, and install the back washing pipe to backwash the foreign substances such as sludge and discharge it out.
