【Example】

 BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 shown in the drawings is, for example, a main body of a sewage basin which is installed in a sewerage pipeline of a general household. The main body 1 is formed, for example, in a substantially box shape made of concrete, and is installed in a buried state with the opening surface substantially matching the installation ground surface. An inflow pipe 5 connected to the upstream side of the sewer pipe system and an outflow pipe 6 also connected to the downstream side of the sewage pipe line are connected to each other in the front-rear direction, and an opening / closing lid for opening / closing the waste water spill body 1 is provided on the opening surface. 4 is attached and detached by itself.

A bag-shaped filter 11 that is detachably connected to the rear end of the inflow pipe 5 and a groove-shaped drain gutter that supports the filter 11 with a mesh body 16 interposed in the sewage basin body 1. And 13 are provided. In addition, at the bottom of the sewage basin body 1, a settling tank 17 for storing the treated sewage dropped from the draining gutter 13 and a communication to the outflow pipe 6 for treating the treated sewage overflowed from the settling tank 17 with a chemical solution. It forms a partition with the liquid chemical agent tank 18 that is operating.

The filter 11 is formed of, for example, a water-permeable synthetic resin bag or a mesh bag having a mesh degree smaller than the size of impurities or the like to be filtered and removed. The filter 11 itself can be replaced by socks or the like woven from nylon fibers or the like in some cases. This filter 11 is covered by the opening of the filter 11 itself on the rear end of the inflow pipe 5 projecting into the sewage basin body 1 and then through a suitable band, ring or other fastening member 12 to the filter 11. The outer periphery of the opening is fixed.

The drain gutter 13 is made of a synthetic resin such as vinyl chloride resin having a substantially semi-circular cross-section with an upper opening in which a large number of drain holes 14 are opened, and flows from the inflow pipe 5 to the outflow pipe 6. It is installed along the front and rear of the sewage basin body 1 with a downwardly sloping water gradient. The drain gutter 13 itself is fitted and placed in a semicircular concave portion above the support projection 15 formed on the front and rear inner side surfaces of the sewage basin body 1 so that it can be inspected and cleaned. It is provided in the main body 1 of the dirty water tank so as to be detachable.

Further, since the filter 11 is disposed on the curved inner surface of the drain gutter 13, the filter 11 and the drain gutter 13 directly contact each other by the detachable mesh body 16. I try not to. That is, the mesh body 16 has a semicircular spacer portion arranged in the center so as to fit in the drainage gutter 13 and the both sides so as to be supported by abutting the inner surface of the sewage basin body 1 in a substantially stretched manner. It is formed integrally with the arranged holder part and is obtained by bending a metal net made of stainless steel, for example. The spacer portion of the mesh body 16 itself prevents contact with the inner side surface of the drain gutter 13 when the supporting filter 11 is expanded by being filled with dirty water and the like, and the filter 11 and the drain gutter 13 are prevented. A gap through which the treated sewage after filtration flows down is maintained so that the treated sewage smoothly drops below the draining gutter 13 through the draining hole 14. In addition, aeration treatment in contact with air is performed during leaching from the filter 11 and falling from the drain gutter 13 to promote purification of sewage by aerobic bacteria contained in the sewage.

Further, the settling tank 17 is provided as the bottom portion of the wastewater basin body 1 itself, and the treated sewage dropped from the filter 11 through the drainage gutter 13 is temporarily stored therein, and is adjoined while precipitating impurities and the like. The chemical solution tank 18 is made to overflow.

The chemical liquid agent tank 18 is defined on the outflow pipe 6 side at the bottom of the wastewater basin body 1 through a settling tank 17 and a partition wall 19, and various kinds of injected drugs, for example, biomedical agents The disinfectant, etc. can be used to treat the treated sewage. When it overflows from the chemical liquid agent tank 18, it is drained and discharged by the outflow pipe 6.

Next, to explain an example of use of the purifying apparatus of the present invention, for example, it is arranged in a sewage pipe system in an ordinary household, and the inflow pipe 5 is on the upstream side and the outflow pipe 6 is on the downstream side. And the filter 11 is connected and fixed to the rear end of the inflow pipe 5. When the wastewater to be treated is drained and reaches the inside of the filter 11, the filter 11 temporarily blocks the wastewater and expands, and at the same time, the filtered treated water is exuded to the outside of the filter 11. The exuded treated sewage flows down onto the draining gutter 13 through the mesh body 16 which separates the filter 11 and the draining gutter 13 at a predetermined interval, and flows down into the settling tank 17 via the draining hole 14. At this time, while exuding from the filter 11 and falling from the drain gutter 13, it is brought into contact with air to perform an aeration process to promote purification of wastewater. Then, in the settling tank 17, the precipitate contained in the treated wastewater is settled and separated, and after overflowing from the settling tank 17 into the liquid chemical agent tank 18, the liquid chemical is treated and discharged from the outflow pipe 6.

Then, for example, the filter 11 is removed once a week, and the contaminants trapped inside are removed to be separately discarded, and the precipitate in the settling tank 17 is the mesh body 16 and the drain gutter 13 It is used while carrying out inspection, maintenance, etc. such as replenishing the chemical liquid agent tank 18 with a predetermined chemical liquid by appropriately removing and removing the same.

[0023]

[Effect of device]

 The present invention is configured as described above, and for this reason, various impurities mainly contained in household wastewater drained from general households, such as food residue, hair, scale, cloth, paper, detergent residue, etc. It can be filtered and removed, and it is discharged after being rendered harmless by chemical treatment such as biotreatment and disinfection, so that it is not necessary to pollute rivers. Moreover, since the captured contaminants are accumulated in the filter 11, the contaminants can be easily removed by cleaning the filter 11, and the maintenance, inspection and the like are easy to handle. Furthermore, it can be installed by changing the sewage basin installed in the existing sewer pipe system, and since the change work is not troublesome, it can be easily replaced with the existing facility and can be installed at extremely low cost. It is a thing.

That is, this is that the present invention is detachably connected to the rear end of the inflow pipe 5 in the main body 1 of the sewage basin which is installed in the sewer system by the inflow pipe 5 and the outflow pipe 6. A bag-shaped filter 11 and a groove-shaped draining gutter 13 for supporting the filter 11 with a mesh body 16 interposed are provided, and the treated wastewater dropped from the draining gutter 13 is stored in the bottom of the drainage basin body 1. This is because the sedimentation tank 17 has been formed, and, although it is a simple device, it is possible to filter and remove various impurities and the like contained in domestic wastewater discharged from general households, for example.

Further, since the bag-shaped filter 11 is connected to the rear end of the inflow pipe 5, various kinds of impurities contained in the inflowing wastewater are surely captured and the treatment for removing the impurities is performed. Only sewage is exuded to the outside. Therefore, for example, the residue of fine foods and the like formed by using the disposer attached to the kitchen equipment can be reliably captured, and the harmful effects of the use of the disposer can be sufficiently removed and prevented. Moreover, at this time, the filter 11 itself is held at a predetermined gap without contacting the inner side surface of the drain gutter 13 by the spacer portion of the filter 11 fitted in the groove-shaped drain gutter 13 having the upper opening. Therefore, the outer surface of the filter 11 can be constantly brought into contact with air. Also, the treated sewage that has flowed down on the draining gutter 13 is diffused by the draining gutter 13 while air is dropped when it is dropped through the draining gutter 13 itself into the settling tank 17 through the draining hole 14. Since it is brought into contact with the sewage, the aeration action during the contact makes it possible to obtain a further purification of sewage by aerobic bacteria.

The drain gutter 13 itself has a water gradient from the inflow pipe 5 to the outflow pipe 6, so that the treated wastewater exuded from the filter 11 can be smoothly drained, and in cooperation with the water drain hole 14, It does not stay on the gutter 13.

Since the mesh body 16 is integrally formed with a spacer portion fitted in the drainage gutter 13 and a holder portion which is abutted and supported on the inner surface of the wastewater basin body 1 in a substantially tensioned manner. It is easy to attach / detach to / from the body of sewage basin 1, and in combination with the drainer gutter 13 which is attached to / detached from the body of sewage basin 1 for cleaning, inspecting inside the body of the sewage basin 1, removing sediment from the settling tank 17, Therefore, it is possible to easily replenish the chemical solution tank 18 with a predetermined chemical solution. Further, the mesh body 16 itself not only prevents the filter 11 held by the mesh body 16 from being damaged, but also keeps a predetermined gap between the draining gutter 13 and the filter 11, so that the water content of the filter 11 may be prevented. It further promotes and assists the separation action from contaminants.

Further, a chemical liquid agent tank 18 for treating the treated wastewater overflowed from the settling tank 17 with a chemical liquid is sectioned and formed at the bottom of the sewage basin body 1, and the chemical liquid agent tank 18 is connected to the outflow pipe 6. Since they are arranged, the treated sewage discharged after the sedimentation treatment in the sedimentation tank 17 can be subjected to various treatments such as biotechnology and disinfection with a predetermined chemical solution.
