简介：主持人语：“世有伯乐，然后有千里马。”是指发现人才需有“伯乐相马”。然而。广东香山衡器集团股份有限公司安全主任石明思却变“伯乐相马”为“伯乐赛马”，将自己的“独门秘籍”——“赛马”机制引入安全管理领域。从而“赛”出安全管理好人才．“赛”出安全生产大环境。

简介：以长期运行的闭合式循环水养殖系统（RecirculatingAquacultureSystem,RAS）中的养殖废水为处理对象,采用序批式厌氧/缺氧/好氧（SBR-A2/O）工艺研究不同碳磷比（COD/ρ（P））对养殖废水脱氮除磷的影响。结果表明：对于TN在50～70mg/L的RAS废水,当COD/ρ（P）〈19.85时,TN和TP去除率较低,随COD/ρ（P）升高,去除率逐渐增加;在COD/ρ（P）≥19.85时,TN和TP去除稳定,平均去除率分别为62.38%±8.33%和62.44%±4.97%。维持COD/ρ（P）在25～30进行试验,RAS废水中各污染物去除稳定,水体中TN、TP、NO-3-N、PO3-4-P、NH_4＋-N和NO-2-N的平均去除率分别为60.61%、62.69%、60.21%、60.46%、45.55%和84.94%。进水为高质量浓度NH_4＋-N（（16.07±1.09）mg/L）废水的条件下,COD/ρ（P）〈22.49时,出水NO-2-N远高于进水,积累明显;COD/ρ（P）≥22.49时,NO-2-N去除率可达100%;NH_4＋-N的平均去除率为87.29%。
