険性がある。[Prior Art] Recently, agricultural chemicals (insecticides, herbicides, etc.) used on golf courses have been widely discussed as a pollution problem because they flow into rivers outside the golf course together with rainwater (or golf course drainage) and pollute the environment. ing. As long as the pesticide is sprayed in an appropriate amount, it will achieve its intended effect, and then it will be absorbed by the grass, adsorbed by the underlying dead leaves, bed soil, etc., and decomposed by microorganisms, making it harmless. However, there is a risk that pesticides that are sprayed in a larger amount than the appropriate amount, or even if the pesticide is sprayed in an appropriate amount, may get mixed into extremely small amounts of water after spraying, seepage water from rainfall, or surface water and flow out.

We have developed a ``system manhole'' that allows rainwater containing pesticides flowing on the surface of the lawn to permeate through the water collection trough and efficiently introduce it into the basin, and in the process of introducing the pesticide, removes the pesticides using activated carbon.

However, if individual wastewater treatment devices are scattered throughout the golf course, it cannot be said that the entire wastewater of the golf course can be reliably treated, and there is a concern about the leakage of untreated wastewater. That is, it is important to establish a system that efficiently collects and treats wastewater in a wide range of areas, at least in the water collection area of a golf course. Further, as described above, in order to treat the wastewater of the entire golf course without leaking with each wastewater treatment device, a very large number of devices are required, which is uneconomical. Furthermore, with only wastewater treatment equipment that is limited to before and after the above-mentioned regulating pond, there are problems in setting the quality and amount of discharged water, and there are problems such as the constant need for operating power, and these are issues that need to be resolved. ing.

Rainwater, etc. (seepage water) containing agricultural chemicals that has permeated underground from the ground is collected by an underground water collection pipe 4. This collected water passes through a water collection pipe 4, a main treatment pipe 5, a water collection manhole 6, a drainage main pipe 7, etc., and is finally collected in an underground reservoir 8, and pesticides are removed in the process. In the underground reservoir 8, water is retained in the gaps of the gravel layer 11 inside the pond shell 10, and a considerable amount of water is stored, and a part of the water is used as gray water for water spraying, car washing, etc. Since bed soil is laid on the gravel layer 11 and grass is planted, the ground surface can be used as a general fairway or rough surface. The underground reservoir 8
Since the surplus water (overflow) flows out through the activated carbon layer 13, pesticides are adsorbed and removed in this process as well. As mentioned above, since pesticides are adsorbed and removed by activated carbon or the like during the process of flowing through the main treatment pipe 5, drainage main pipe 7, or manhole 6 leading to the underground reservoir 8, so to speak, each water collection area of the golf course Since the entire area will be treated to prevent agricultural chemicals from running out, there is no need to worry about any leakage. Furthermore, there is a degree of freedom in setting the quality and quantity of discharged water.

のである。Embodiments Next, illustrated embodiments of the present invention will be described. FIG. 1 shows the planar layout of a course design at a certain golf course. In particular, the two-dot chain line 40 on the outer periphery means a so-called watershed, and the area surrounded by the two-dot chain line 40 is one water collection area. . The drainage from this water collection area is configured to be finally led to a regulating pond 9. That is, under the ground of each green 3, fairway 2, and teeing ground 1 belonging to this water collection area, there is a main water collection pipe 4 as shown in detail in FIG.
A net of water collection pipes 4 is installed as a collection of many branch water collection pipes 4b branched like branches from a, so that rainwater containing agricultural chemicals can be collected over a wide area without leaking. The details of the configuration of the main water collection pipe 4a and the branch water collection pipe 4b are as follows:
As an example, as shown in FIG. 3, a groove 45 with a width of about 300 mm and a depth of about 400 mm is dug under the mixed sand 41, river sand only 42, gravel layer 43, and crushed stone No. 4 layer 44 that make up the green 3. A netron pipe 46 with a diameter of about 150 mm for the main line and about 100 mm for the branch line is laid in the lower part of the groove 45, and the surrounding area is also densely filled with crushed stone No. 4 47. Therefore, rainwater that permeates underground from the surface of the green 3 is widely introduced into the groove 45 through the crushed stone layer 44, collected, and guided downstream through the netron pipe 46.

ター管15を直接流れてマンホール6へと落下する。The permeated water collected in the main water collection pipe 4a having the above structure is first guided to the water collection manhole 6 by the main treatment pipe 5. The water is then led from the water conduit 50 to the underground reservoir 8 via the drainage main pipe 7 that connects each relay manhole to the manhole in series. Note that the main treatment pipe 5 and the main drainage pipe 7 may also be installed in the configuration of the water collection pipe 4a or 4b shown in FIG. 3, respectively. Alternatively, as shown in FIGS. 5 and 6, it is also possible to construct an underdrain drainage channel that uses activated carbon to remove pesticides from wastewater. In FIGS. 5 and 6, activated carbon 16 with a relatively large particle size is placed on the lower half side of the cloth filter tube 15, which serves as the main channel, as the core, with a width of 30 cm and a depth of 10 to 20 cm.
They are arranged with a layer thickness of about cm, and a crushed stone layer (or gravel layer) 17 is arranged on the upper half side. Therefore, when the amount of water infiltrating from the fairway 2, etc. is as low as normal, rainwater, etc. infiltrates from the crushed stone layer 17 to the activated carbon layer 16, flows downstream in the activated carbon layer 16 according to the flow gradient, and contacts between them. Pesticides are adsorbed and removed during flow. However, in the vicinity of the manhole 6, the water hits the manhole wall and returns to the cloth filter pipe 15 in an overflowing form, and falls into the manhole 6. When the amount of seepage water is large due to heavy rain, etc., excess water that does not flow through the activated carbon layer 16 flows directly through the cloth filter pipe 15 and falls into the manhole 6.

る。However, as a means to avoid the trouble of constructing the above-mentioned culvert drainage channel, the method shown in FIG. 7 or 8 may be used.
It is also possible to remove pesticides using activated carbon only in the part that flows into the manhole 6 as shown in FIG. What is shown in FIG.
A relatively short sub-pipe 20 that detours to the manhole 6 is branched from the bottom of the pipe at a position slightly upstream of the inlet 25a, and a long and narrow bag filled with activated carbon is inserted into the sub-pipe 20 to form a filtration layer. 21 is formed. Further, a filter layer 22 is provided on the upstream end surface of the filter layer 21 . When the amount of waste water flowing through the inflow pipe 25 is normal, all the waste water flows into the sub pipe 20, flows while coming into contact with activated carbon, and agricultural chemicals are adsorbed and removed. If the amount of water that exceeds the allowable value of the secondary pipe 20 flows through the inflow pipe 25 due to heavy rain, etc., the excess water will flow through the secondary pipe 20 and directly from the inlet 25a to the manhole 6.
flowing inward. According to this configuration, the filter layer 22
In addition to being able to easily replace the filter layer 21, it also has the advantage of being structurally inexpensive to construct. The embodiment shown in FIG. 7 shows a structure in which the head difference between the inflow pipe 25 and the outflow pipe 26 can be made sufficiently large. On the contrary, FIG. 8 shows an example in which it is difficult to ensure a sufficiently long effective length of the filtration layer 21 because the head is not large enough. In short, this is a configuration in which the branching point of the secondary pipe 20 is moved far upstream of the inflow pipe 25, and the secondary pipe 20 is installed substantially parallel to the inflow pipe 25 for a sufficiently long length. In the case of this embodiment, the bag filled with activated carbon 21 is inserted and installed into the sub-pipe 20 from the outlet side of the sub-pipe 20.

目詰まりが防止される。[0012] Removal of agricultural chemicals in wastewater can also be carried out in the manhole 6 having the structure shown in FIGS. 9A, B, and C. That is, the main treatment pipe 5 or the main drainage pipe 7 is the inflow pipe 2.
5. The inside of the manhole 6 connected as the outflow pipe 26 is separated from the connection side of the inflow pipe 25 and the outflow pipe 26 by the partition wall 27.
It is divided into two rooms with a connecting side. This manhole 6 is considerably deeper than a normal manhole (especially the outflow pipe 2).
6) with a considerable depth from the location of the outlet 26a. At the bottom of the partition wall 27, there is a communication port 28 of an appropriate size (
Therefore, the two rooms inside the manhole 6 are formed into a U-shaped flow channel. The height position of the top end of the partition wall 27 is approximately the same height as the lower end of the inlet port 25a of the inflow pipe 25. This is because of heavy rain etc. Inflow pipe 2
When the amount of water flowing in from 5 is large, the inflow water directly exceeds the top of the partition wall 27 and overflows to the outlet 26a of the outflow pipe 26, thereby ensuring a sufficiently large amount of water. Granular activated carbon 29 is filled in two rooms in the manhole which are divided into two by the partition wall 27. Activated carbon 29 is filled in a series of flow channels from a position lower than the inlet 25a of the inflow pipe 25 to a position lower than the outlet 26a of the outflow pipe 26. A filter layer 30 is provided on each upper surface of the activated carbon 29. Therefore,
The normal amount of water that has fallen into the manhole 6 from the inflow pipe 25 flows through a U-shaped flow channel that is divided into two by a partition wall 27 and communicated by a communication port 28, while being in contact with the activated carbon 29 filled there for a sufficiently long time. In the process of this contact flow, pesticides in the wastewater are adsorbed and removed by the activated carbon 29. The thus purified waste water exits through the outflow pipe 26. Sediment contained in the wastewater flowing in from the inflow pipe 25 is removed by the filter layer 30, and clogging of the activated carbon layer 29 is prevented.

である。FIG. 12 shows an embodiment in which activated carbon 29 is installed only in a manhole 6 divided into two by a partition wall 27, particularly in a room to which an outflow pipe 26 is connected. In this case, the activated carbon 29 is packed in a cloth bag. A spacer 31 having a water-permeable structure is installed at the manhole bottom 6a, and the cloth bag containing the activated carbon is inserted onto the spacer 31. The activated carbon 29 is filled to a level lower than the outlet 26a of the outlet pipe 26, and a filter layer 30 is installed on the upper surface thereof. In the case of this embodiment, the earth and sand components contained in the wastewater are removed from the inflow pipe 25.
When water falls into the manhole 6, it settles in the room on the inflow side and is separated, thereby preventing clogging of the activated carbon 29.
