Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention is useful for concretely and statistically understanding the effects of pesticides, etc. on golf courses and surrounding areas,
Furthermore, the present invention relates to a monitoring device and a monitoring storage tank used therein, which will be extremely useful as a measurement means for providing economical and effective measures for this type of countermeasure in the future.

(Conventional technology) Recently, it has been pointed out that pesticides sprayed on golf courses are causing pollution of the surrounding living environment and destruction of nature, and the national and local governments are considering regulating the types and amounts of pesticides used. It has become.

It goes without saying that the problem of the surrounding environment being contaminated by pesticides sprayed at golf courses should be resolved regardless of the existence of legal regulations.

Therefore, from this perspective, the applicant has already proposed various proposals that outline the use of adsorbents to remove agricultural chemicals used at golf courses when they are contained in seepage water and permeate into the ground. It is carried out. In addition, several proposals have already been made by the present applicant for the purpose of removing agricultural chemicals used in golf courses.

(Part 1 to be solved by the invention) By the way, the problem of contamination caused by the leakage of agricultural chemicals into the surrounding water system, which had been a problem in the past, can be practically solved by the method of removing agricultural chemicals used in golf courses proposed by the present applicant. However, depending on the location, golf courses may have different topography and groundwater systems1.
Even if appropriate removal measures are designed depending on the annual rainfall, etc., over a long period of time, pesticides may actually flow out as designed at the golf course where the measures have been taken. It is desirable to confirm that prevention has been achieved on a case-by-case basis.

Therefore, the present inventors have studied various methods that are effective when periodically checking the removal status of agricultural chemicals used at golf courses and the rate at which the agricultural chemicals used permeate into the ground. Then, by pumping out the water that has permeated into the ground during a predetermined period and chemically analyzing the components in this water, it is possible to easily monitor the presence or absence of pesticides that may be contained in the water that has permeated into the ground. However, the present invention was developed based on the belief that this method is suitable as a method for monitoring sprayed pesticides on golf courses with large areas.

That is, an object of the present invention is to provide a storage tank for monitoring agricultural chemicals, etc. contained in water in the ground of a golf course, which makes it easy to periodically take out ground seepage water at the golf course as sample water for water chamber inspection. It is in.

Another object of the present invention is to create a system that allows sample water to be easily taken out from monitoring and storage tanks that are scattered throughout a wide area, such as a golf course, using a vacuum pump or an eXactor device. An object of the present invention is to provide a storage tank for monitoring having a structure that is similar to the above.

Yet another object of the present invention is to provide the above-mentioned monitoring storage tank, which has a structure in which old water is drained and fresh ground seepage water is always stored in the storage tank.

Another object of the present invention is to use the monitor storage tank described above.
lJ! Our objective is to provide a unique monitoring device.

Means and Effects for Solving Problem I) The characteristics of the storage tank for monitoring pesticides, etc. contained in water in the ground of a golf course of the present invention, which is provided to achieve the above object, is that it is buried in the ground of a golf course. a storage tank having an internal volume capable of storing a predetermined amount of water; a water intake port provided so that water flowing down in the ground flows into the storage tank container; Strainer means such as a net installed near the water intake to prevent lumpy solids in the ground from entering the storage tank container, and a sample water intake installed so that the water in the storage tank container can be collected from the ground. and an outlet.

Storage tanks like the one mentioned above have become a problem in recent years, especially when they are installed on the ground directly under or around greens or teeing grounds, where it is necessary to spray large amounts of pesticides, etc. at golf courses. It can be an important indicator for determining the effectiveness of treatment measures against pesticide pollution, etc., and for implementing even more effective measures.

Furthermore, in order to use the storage tank of the present invention more effectively, a sample water outlet should be provided as a connection port for a means for sucking water from the ground so that the water in the storage tank can be easily collected from the ground. This is preferable, as this reduces the work required to supply samples to testing institutions, which is normally required to detect and confirm the presence of pesticides, etc., which are usually in very small amounts or are not substantially contained. It has the advantage that it can be done quickly and easily.

Moreover, as a particularly preferred embodiment of the present invention, it is preferable that the structure of the storage tank container is provided such that the latest water is always stored inside the storage tank container. Problems such as the accumulation of data diluted by methods such as data with a large dilution amount (data with virtually no value) can be solved by simply allowing a predetermined waiting period. Because it will be. As the structure of such a storage tank container will become more concretely clear from the examples described below, in general, water is supplied from the bottom of the storage tank container at a position below the water intake port where water flows into the storage tank container. This can be achieved by providing a drainage outlet to discharge overflow.

(Example) The present invention will be described below based on embodiments shown in the drawings.

FIG. 1 is a diagram for explaining one embodiment of the monitoring storage tank of the present invention, and in this figure, 2 is the main body of the storage tank 1, which has a cylindrical shape, and is generally buried in the ground. Since it is used for a long period of time, it is constructed using corrosion-resistant materials such as stainless steel, glass, inorganic materials, or plastic materials that do not absorb agricultural chemicals.The bottom part 3 is closed, and the upper part A single layer strainer 4 made of stainless steel is provided on the top surface to prevent dirt and foreign matter from entering and accumulating inside. The size of such a container is not particularly limited, but it can range from several hundred mm in diameter (for example, 300 mm) to several A to several +1 (for example, 20 mm in diameter).
A container having a size of about f) is usually preferably used.
