JPH054081A - Device for removing agricultural chemical in golf course - Google Patents

Abstract

PURPOSE:To effectively decompose and remove the agricultural chemicals in a golf course and to reutilize the water freed of the chemicals. CONSTITUTION:This device for removing the agricultural chemicals in a golf course 1 is provided with a water collecting tank 5 for storing the chemicals sprinkled over the green 2 of the course along with rain water, a treating tank 6 having an appropriate number of the internal UV source 7 and a gas collector 8 for collecting ozone and a water pipe 9 for delivering the water treated by the UV and ozone. The chemicals content in the waste water introduced into the treating tank 6 is reduced below the standard, the treated water is delivered, and then the untreated water in the water collecting tank 5 is introduced into the treating tank.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to improvement of a golf course pesticide removal apparatus.

[0002]

2. Description of the Related Art In recent years, a large amount of insecticides, herbicides, and bactericides have been sprayed on golf courses, and pollution caused by agricultural chemicals has become a social problem. Therefore, in some cases, a method of using a pesticide having a low concentration or an operator weeding without using the pesticide has been implemented in some cases.

[0003]

[Problems to be Solved by the Invention] However, according to the method of using a pesticide having a low concentration, insecticide, sterilization and weeding become insufficient, and the method of weeding by a worker over a wide area requires considerable labor. There are drawbacks.

The present invention has been made in view of the above points, and it is possible to effectively decompose and remove pesticides in a green field on which most of the pesticides in a golf course are sprayed, and the pesticides are decomposed and removed. It is an object of the present invention to provide a pesticide removal device for golf course which can reuse water.

[0005]

The present invention has the following constitution in order to solve the above problems. In other words, a water collecting tank that collects pesticides scattered on the green of the golf course together with rainwater,
A treatment tank having an appropriate number of ultraviolet light sources and a gas collection gas for collecting ozone generated by the ultraviolet light sources, and a water supply pipe for sending out treated water treated with ultraviolet rays and ozone are configured. Then, the pesticide contained in the water sent to the treatment tank is decomposed to below the standard and sent out, and then the untreated water in the water collecting tank is injected into the treatment tank.

[0006]

[Operation] According to the golf course pesticide removal device having the above structure, the pesticides scattered on the green are stored together with rainwater, and the treated water treated with ultraviolet rays and ozone is sent out, and then the untreated water in the water collecting tank is treated. Therefore, the pesticide contained in the water sent to the treatment tank can be reliably decomposed to below the standard, and the treated water can be reused by storing it in the reservoir.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to FIG. In the figure, 1 is a golf course green field, 2 is a green field,
Reference numeral 3 is a floor soil located on the lower surface of the green 2, and 4 is a water-blocking sheet installed on the lower surface of the floor soil 3, and is made of, for example, a rubber material. Reference numeral 5 denotes a water collecting tank for storing water that has penetrated into the floor soil 3 and collected by the water blocking sheet 4, and 6 denotes a treatment tank, into which water from the water collecting tank 15 flows. Reference numeral 7 is an ultraviolet light source arranged inside the processing tank 6, and is constituted by using, for example, 60 high-pressure discharge lamps of 110 watts. Reference numeral 8 denotes a gas collecting gas that collects ozone generated from an ultraviolet light source, and injects the collected ozone into the inside of the processing tank 6 to process the pesticide together with the ultraviolet light. The treated water treated with ultraviolet rays and ozone passes through the water pipe 9 and reaches the reservoir 10.
Sent to. Further, the pesticide contained in the water sent to the treatment tank 6 is decomposed to below a standard and sent out, and then new untreated water is injected into the treatment tank from the water collection tank. According to the ultraviolet rays of 185 nm and 254 nm and ozone, for example, the following insecticides, herbicides and fungicides can be decomposed and removed. Pesticides include MEP (phennitrothion), diazinon and isoxathione, herbicides such as isoprothiolane, iprodione and captan, and fungicides such as simazine (CAT), napropamide and butamifos.

[0008]

EFFECTS OF THE INVENTION Since the present invention is configured as described above, pesticides sprayed on the green are stored in a water collecting tank together with rainwater,
The pesticides are decomposed and removed by ultraviolet rays and ozone, and the treated water is sent out, and then the new untreated water is treated, so the pesticides contained in the water sent to the treatment tank must be below the standard. Can be disassembled. In addition, the treated water is stored in a reservoir and sprayed again on the green, so that the water can be reused.
