Urban non-point pollutant treatment device using ecological trench

摘要

The present invention relates to a municipal non-point pollutant treatment facility for purifying the initial rainwater containing non-point pollutants deposited on the road while rainwater flows through roads, parking lots, and the like, and in particular, non-point pollutants from initial rainwater through microbial treatment and filtration. It relates to an urban non-point pollutant treatment device using an ecological ditch capable of completely removing and separating the oil. The configuration of the present invention in the initial rainwater non-point pollutant treatment apparatus, allowing the passage of sunlight and air to allow vegetation plants (grass, buttercup, clover, etc.) to grow, soil layer, vegetation plant for non-point pollutant treatment And an upper protective grating for protecting the processing apparatus body; A treatment apparatus body composed of concrete or synthetic resin and forming an urban non-point pollutant treatment apparatus structure; An artificial trench formed in the processing apparatus main body in the longitudinal direction of the processing apparatus main body, and a filtration outlet formed in a tunnel shape along the longitudinal direction of the artificial trench on the inner surface of the artificial trench, and filled with Masato and volcanic stone on the upper part of the filtration outlet. An ecological trench comprising a filter soil layer in which adsorption and microbial decomposition occur, and a planting part in which vegetation plants are planted in the filter soil layer; A rainwater wall having a height higher than an upper end of the planting part so that the initial rainwater formed in the longitudinal direction to one side of the ecological trench and containing nonpoint pollutants is guided to the ecological trench, and the rainwater after the initial rainwater is overflowed; A treated water outlet formed at a lower end of the overflow wall and in communication with the filtration outlet of the ecological trench to discharge the treated water; The rainwater partitioned in the longitudinal direction by the overflow wall and containing the non-point pollutant is discharged to the treated water purified by the ecological trench to the bottom and the rainwater after the initial rainwater is flowed out from the top of the ecological trench to discharge Characterized in the configuration of the municipal non-point pollutant treatment apparatus using an ecological ditch characterized in that it comprises a.
