Abstract

The invention discloses a highway ecological filter ditch infiltration system in the field of highway rainwater pollutant filtration, which has the effect of removing runoff pollutants, comprising a rectangular groove, an ecological filter bed and water outlets arranged at the bottom of the rectangular groove at a certain distance The ecological filter bed includes soil layer, multi-layer filter material layer, purification medium layer and base drainage layer with large gaps from top to bottom, and geotextiles are arranged between each layer. The structural system integrating filtration, ventilation and drainage effects can realize various pollutants in road runoff, especially dissolved nitrogen, high removal efficiency, good operation stability, self-ventilation and other functions without additional construction, and can be used for road sewage Filtering.

Description

technical field [0001] The invention relates to a highway ecological filter ditch, in particular to a percolation system. Background technique [0002] While my country's road industry is booming, the disturbance and damage to the ecosystem are also increasing. Frequent traffic activities, vehicle exhaust emissions, tire and road wear, component corrosion, and oil leakage lead to the accumulation of a large number of suspended particles, heavy metals, nutrients, organic matter and other pollutants on the road surface. When precipitation forms road runoff, these harmful substances are If it is carried into the water or soil, it will cause the water quality of the receiving water to deteriorate, the aquatic ecology to be destroyed, and the surrounding soil to be polluted by heavy metals. [0003] In order to improve the water ecosystem and alleviate the waste of land resources caused by the widely used sink treatment measures, source treatment measures to deal with stormwater...
