Abstract:
Runoff thermal pollution is an important aspect of water pollution and an important cause of ecological environment destruction of urban water bodies.Bioretention is one of the most effective measures to alleviate urban stormwater runoff thermal pollution. Through soil column bioretention experiments with different fillers under the condition of artificially simulated uniform rainfall, reduction effect of bioretention on urban stormwater runoff thermal pollution under different rainfall characteristics was explored. The thermal load reduction effects of bioretention with different fillers from large to small were as follows: slag, quartz sand, ceramsite and zeolite. The higher the temperature of the runoff, the greater the amount of heat it carried, and the higher the heat reduction rate of the bioretention would be obtained. The contribution of volume reduction to the stormwater runoff thermal pollution reduction was greater than that of heat exchange.
