In the present invention, the pretreatment apparatus 200 including the automatic washing screen is operated such that raw water flowing into the bypass tank in a normal natural descent mode forms a water flow by the water head difference in the pretreatment apparatus 200, The raw water flowing through the inflow conduit 210 flows into the treatment device through the drain port formed at one side of the wall separating the bypass tank and the first settling tank. When the flow rate exceeding the treatment capacity is inputted, (Aka raw water bypass line: 220) installed in a high position is bypassed.

The raw water flowing into the primary settling tank through the water outlet formed in the wall dividing the bypass tank and the primary settling tank passes through the first settling tank through the water outlet formed in a slightly lower position for natural descent to the other side wall of the water outlet, As a result, the kinetic energy of the raw water of the raw water plays a role of improving the speed of sedimentation of sedimentary substances or similar heavy particulate matter contained in the raw water, thereby separating and removing precipitating substances.

Since the raw water discharged from the primary settling tank through the water sump is still in the state of floating sludge or sludge, it is necessary to remove the pore through the pretreatment because the pore of the water purification plant of the subsequent treatment apparatus can be blocked.

The raw water flowing from the primary settling tank to the automatic washing filter unit tank 230 through the water outlet still contains a cylindrical screen 236 made of a wedge wire to remove a high concentration SS component containing floating sludge or sludge So that the high-concentration SS component remaining on the filtration surface of the cylindrical wedge wire screen 236 does not obstruct the slot, so that the screen filtration surface and the 0.5 to 5 mm clearance The screen cleaning brush 239 is driven by the power source 235 including a geared motor which is installed on the other side of the raw water into which the raw water flows.

The brush 239 is attached to the brush cleaning rotary shaft 237 so that the rotary shaft 237 rotates in a predetermined direction when the rotary shaft 237 rotates and pushes the sludge in a direction opposite to the direction in which the raw water flows in the cleaning process .

That is, when the raw water is introduced into the wedge wire cylindrical screen, the treated water escapes through the filter surface slots of the screen and the sludge filtered on the screen of the screen is deposited while remaining deposited on the slot, I can not do my function.

Therefore, when the rotating shaft 237 is continuously rotated by applying the automatic cleaning brush 239 using external power, the screen filtration surface 236 is cleaned, and when the sludge is introduced together with a part of the raw water The filtration surface 236 is cleaned while being directed in the opposite direction.

The settled sediment and solid matter including the suspended solids and the wedge wire screen are washed and the generated sludge 262 is discharged to the outside of the pretreatment apparatus through the sludge discharge tank located on one side of the Bypass tank.

At this time, the solid material including the sedimentable substance and the suspended solid is transferred to the sludge discharge tank, and the sludge discharge pump 260 installed in the sludge discharge tank is charged to the suction force of the pump 260, which is periodically or intermittently operated To the sludge discharge tank from the primary settling tank.

Raw water that has undergone a pretreatment process to remove precipitate and sludge contained in raw water still contains nutrients and organic components dissolved in water.

A purified water purification apparatus 300 is installed to remove organic matter and nutrients contained in the raw water.

The purified water purifying apparatus 300 is installed at the lowermost end of the distribution pipe line 350 formed of a pipe for uniformly distributing raw water having undergone the pretreatment process.

The pretreated treated water flowing through the pipe line of the distribution pipe line 350 is distributed through a space between the large crush stone and the large crush stone 340 and then finely divided through the crush stone 330 loaded on the upper crush stone, The pores formed between the sand layers constituting the soil 320 where the planted plant is planted are reached to the roots of the planted pure water plant, and thus the introduced raw water can reach the roots.

The organic matter and nutrients contained in the raw water are absorbed through the root of the purified water plant 370, and the absorbed organic matter and nutrients are consumed as nutrients necessary for the growth of the plant, and the water purification plant 370 grows do.

In addition, the living organisms attached to the roots and stem of the plant are also used for the propagation of bacteria by regulating the organic and nutrients contained in the raw water. This mechanism enables exponential growth of bacteria , And the raw water flowing through it is treated with water.

The method of water treatment using living microorganisms attached to the roots and stem of the purified water plants is similar to the water treatment method using microbial growth in a kind of sewage treatment plant.

The present invention is applied to a region where a sewerage line and a sewerage treatment plant are not installed in a natural village, or where the sewerage is continuously inflowed into the sewerage system to cause civil complaints, can do.

In addition, when the water quality standard of discharged water is exceeded due to the inflow amount exceeding the treatment capacity in the sewage treatment plant or the wastewater treatment plant, it is possible to maintain the water quality standard for the excess capacity with low facility investment cost and operating cost. ㆍ It can be applied to wastewater treatment plant.

In the case of precipitation, the influent quantity of the sewage treatment plant flows into the 3Q, which is three times the treatment capacity (1Q) of the sewage treatment plant, and the sewage treatment plant It is possible to prevent river pollution by processing in connection with wastewater treatment plant.

If sufficient site area is available, the sewage treatment plant and wastewater treatment plant can be replaced by a multistage process in which the water treatment process of the present invention is repeatedly applied.
