Control strategies for hydrogen sulphide production in stormwater retention ponds

如果不加以管理，雨水蓄水池排放的硫化氢可能会造成水质和水量问题，对财产价值、人类健康和流域健康都是有害的。位于埃德蒙顿市的数百个雨水蓄水池和人工湿地中，有几个会产生高浓度的硫化氢。埃德蒙顿市在这些池塘中使用的硝酸盐产品未能抵消硫化氢的产生。对产生硫化氢的雨水滞留池的特征研究工作很少。由于缺乏关于这些池塘的信息，很难实施有效的硫化氢排放控制战略。因此，对埃德蒙顿雨水化学和微生物学的研究可能会提出一种缓解这一问题的方法。

If not managed, hydrogen sulphide (H2S) emission from stormwater retention ponds can cause water quality and quantity problems that are detrimental to property values, human health, and watershed health. Several of the hundreds of stormwater retention ponds and constructed wetlands located across the City of Edmonton generate high levels of H2S. Nitrate products applied to these ponds by the City of Edmonton failed to counteract H2S production. Little work has been done to characterize the stormwater retention ponds that produce H2S. The lack of information regarding these ponds has made it difficult to implement effective control strategies for the emission of H2S. Therefore, a study of Edmonton's stormwater chemistry and microbiology might suggest a method to alleviate the problem.
