LID-Based Ecological Planting Groove for Road Runoff Purification Research
Publication: International Low Impact Development Conference China 2016: LID Applications in Sponge City Projects
ABSTRACT
In order to control road runoff’s impact on adjacent water environment, this paper developed an ecological planting groove with multi-layer structure including planting soil layer, infiltration purification layer, and aquifer layer. In addition, a design method based on initial runoff purification and drainage was proposed. A series of indoor experiments with different sawdust-sand mixing volume ratio in 1:3, 1:4, 1:5 were conducted to analyze the impact of the ratio on nitrogen and phosphorus removal effect. The removal efficiency in this three ratios are 80.71%, 83.40%, 85.63% for NH3-N; 80.13%, 83.87%, 84.38% for TN; and 92.06%, 91.03%, 88.55% for TP. Results show that optimal purification effect of different mixed packing ratio was 1:4 (sawdust: sand). Based on Erhai Lake East Ring Road, a field test showed that water quality purified by ecological planting groove is superior to the value of grade-III standard of surface water.
