<p>PURPOSE:To provide a novel industrial waste disposal method utilizing a submerged pit as it is without performing drain treatment. CONSTITUTION:A pit 5 is partitioned by a partition wall 3 to form filling sections having predetermined length and a shaft 6 and drain pit 8 are arranged to both ends thereof and a pipe 7 is formed to the shaft 6 and the drain pit 8 up to the filling sections and water is held in the pipe 7 to make the system watertight and a durable spherical capsule 1 with a predetermined diameter having industrial waste 2 hermetically sealed therein is charged in the pipe 7 of the shaft 6 and the water stream due to the piston action caused by the falling motion of the durable spherical capsule 1 in the pipe 7 is utilized to successively fill the pit 5 with the durable spherical capsule. By this constitution, a closed pit subjected to submersion treatment being a land not used as an industrial waste disposal area insufficient at the present time is used as it is and the space being the pit is filled to eliminate the possibility of land subsidence to achieve the effective utilization of a land.</p> |
