から重金属を濾過するようにしている。Conventionally, a hole is dug at the disposal site, the bottom and inner circumference of the hole are covered with an impermeable sheet, and industrial waste is dumped into the hole to prevent heavy metals from escaping. There is. Then, the taisei is lined with cobblestones, and the waste water containing heavy metals that has accumulated in the taisei is collected through a drain hole that has been drilled in advance on the bottom of the taisei, and the heavy metals are filtered out from there. There is.

ようにすることを特徴としている。(Means for Solving the Problems) In order to achieve the above object, the present invention covers the bottom and inner circumferential surfaces of an almost vertical vertical hole that reaches the bedrock with an impermeable sheet. In an industrial waste treatment method, industrial waste is dumped into a vertical hole covered with a sheet, and sewage flowing down to the bottom of the vertical hole is collected from a drain hole drilled near the bottom. After laying branch coral to a predetermined thickness on the bottom, dumping industrial waste on top of the spread coral layer, and laying coral sand or porous material to a predetermined thickness. The method is characterized in that the steps are repeated alternately to fill up the vertical hole while alternately forming layers of industrial waste and layers of coral sand or porous material.

Contains elements such as s, manganese, hupart, and chromium. These elements have been weathered by the life activities of reef-building corals, which are coelenterates. These corals are extremely porous. By the way, when you look at a piece of coral sand with a microscope, you can see that it has an extremely large surface area, with countless small pores of about 10 to 50 microns opening in every corner, just like the holes of a root. .

を介して回収される。(Function) When industrial waste is disposed of according to the method of the present invention, a layer of branch coral is formed on the sheet covering the bottom of the vertical hole, and on top of that, a layer of industrial waste and coral sand are formed. Alternatively, the geological structure consists of alternating layers of porous material. As a result, the sewage flowing down from the earth's surface repeatedly passes through the layer of coral sand or porous material to filter out the heavy metals contained therein and to shift the pH value of the sewage to the alkaline side. In this way, the wastewater with low heavy metal content and low acidity reaches the final stage, and after the heavy metals are further filtered through the layer of branch corals at the bottom, it is collected through the drain hole.

う利点が得られる。(Effects of the Invention) As described above, according to the method of the present invention, the wastewater flowing down to the bottom of the vertical hole has a low content of heavy metals and low acidity. Therefore, the possibility of the sheet being torn due to acidic deterioration is extremely reduced. Further, even if the sheet is torn, the advantage is that the content of heavy metals is small.
