The leachate a that is retained and seeps out of such waste or contains contaminants as rainwater passes through the waste migrates toward the bottom 4,
Since it is blocked by the water-blocking sheet 5, it does not leak into the bottom 4 and penetrate. The leachate a enters the drainage pipe 6a through a plurality of holes of the drainage pipe 6a via the filter material 6c, and after being collected, the leachate is stored through the leachate guide pipe 12. The water is drained and stored in the unit 11, and then discharged by a pump (not shown), and then purified and processed.

In order to prevent the leachate a from leaking, it is important that the leachate a be quickly discharged and that the leachate a be not stored in the waste layer for a long period of time. In collecting and draining water, since the leachate guide pipe 12 has a small diameter and the leachate storage unit 11 is small, the drainage capacity is small, and as a result, leachate stays in the disposal site for a long time, There was a problem in obtaining a safe storage function and a quick purification function.

Function is required. In order to realize safe storage and early stabilization of waste, leachate should not be stored and retained in the landfill, preventing leakage of leachate, suppressing deterioration of leachate quality,
It is important to promote the natural purification action of waste.
However, in conventional disposal sites, the method of temporarily storing leachate in landfills is generally used due to the relationship between the expected safety during maximum precipitation and the scale of water treatment facilities. There was a concern about the effect on each function required for.

Since the leachate was retained for a long period of time, a rapid purification function could not be obtained.

防止されるとともに、景観性が向上する。That is, the following effects can be obtained. a. Since the amount of water spray is adjusted, the amount of leachate can be set extremely small, so that the risk of leakage of leachate is reduced and the treatment capacity of the water treatment equipment is reduced. b. By setting the most effective watering amount and chemical for each target waste, the purification action of the waste using water as a medium is stably promoted. It is also possible to respond flexibly to future changes in the composition of waste. c. The circulation system that reuses the treated water for watering can suppress the discharge of treated water to the outside of the system and reduce the load on the surrounding environment. d. Even in the event of an unexpected event, such as a large amount of rainwater entering a landfill site due to a storm or the like, it is safe because a water treatment facility is provided. e. The cover during reclamation prevents the reclamation work from being affected by the weather, prevents dust and the like from being scattered around the reclamation work, and improves the landscape.

Alternatively, the leachate may be guided to the water treatment facility 36.
According to this, the pump 34a can be made unnecessary. The water from the water treatment facility 36 is discharged to the water storage tank 90d by the pump 36f.

According to this, the durability of the leaching water accommodating portion 32 is increased with respect to the pressure from above, and the leaching water is accommodated in the resin pipe 70, so that the accommodation capacity is not reduced. In this case, the reinforcing plate 32f and the lid plate 32e may be removed.

能が期待できる。According to the first aspect, since leachate is obtained by sprinkling an appropriate amount of water onto waste while covering the waste disposal site with a roof, a large amount of leachate is disposed. Since the water does not stay in the site and large water pressure is not generated by the leachate, the leachate can be prevented from leaking and a safe storage function can be obtained.Moreover, since the leachate quickly descends to the bottom of the disposal site, The effect of washing out waste can be expected and a quick purification function can be expected.
