摘要:
径流热污染是水污染的重要方面，也是城市水体生态环境破坏的重要原因，生物滞留是缓解城市雨水径流热污染最有效的措施之一。通过不同填料的生物滞留实验，在人工模拟均匀降雨的条件下，探究了在不同降雨特征下不同填料生物滞留设施对城市雨水径流热污染的削减效果。结果表明，不同填料生物滞留设施热负荷削减效果从大到小依次为：炉渣、石英砂、陶粒、沸石；径流温度越高，所携带的热量越大，生物滞留设施的径流热污染负荷削减率也越高；体积削减对生物滞留设施削减雨水径流热污染的贡献大于热交换。
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.
