High efficiency non-point pollution abatement device

摘要

The present invention relates to a high-efficiency non-point pollution reduction apparatus comprising: a cylindrical body having an internal space, and comprising an inflow pipe formed on one side to take rainwater containing non-point pollution sources, and a discharge pipe formed on the other side to discharge the rainwater after the removal of the non-point pollution sources; an entirely cylindrical purification unit formed in the center of the body to be floated above the floor of the body, and removing the non-point pollution sources contained in the rainwater taken through the inflow pipe; an eddy groove spirally formed inside the inflow pipe to induce the separation of residual non-point pollution sources in the rainwater by inducing an eddy in the rainwater; and at least one fixing bar connected to the purification unit, and supported by the body to fix the purification unit. Therefore, since the non-point pollution sources remaining in the rainwater flowing into the body are gradually reduced or removed for purification through a filter of the purification unit and the purified rainwater is discharged to the outside, river water can be prevented from being polluted by rainwater containing non-point pollution sources and the death of fish and disturbance of the ecosystem caused by polluted water can be prevented. Moreover, since the filter of the purification unit is conveniently cleaned from the outside and precipitates on the floor of the body are conveniently removed through a precipitate removing unit, the apparatus can be conveniently managed, and also, the permanent use of the apparatus can be induced to secure its universality of use.
