摘　　要：针对深圳湾浅水滩涂受污染底泥产生臭味的问题,采用复合铁盐生化试剂进行除臭处理,该技术从底泥中H2S的生成机理入手,针对性地消耗底泥中已产生的H2S和控制H2S的产生源头。处理结果表明:底泥的外观明显改善,修复后底泥呈现与自然健康底泥一致的颜色;修复后底泥不含可溶出H2S,底泥中H2S的释放源得到完全消除;更为重要的是,原底泥较为完好的生态系统得到了保护。该技术被证实为环境友好型底泥修复技术。To address odor emitted from polluted sediments in intertidal zone of Shenzhen Bay,composite ferric salt biochemical reagent was used for odor control. According to the formation mechanism of H2S in the sediment, the method could consume the emitted H2S and control H2S emission. As a re- suit, the appearance of sediment was significantly improved, which was similar to the healthy one. The sediment after treatment did not contain soluble H2S, indicating that H2S emission could be eliminated completely. More importantly, the sediment ecosystem was well preserved. This method for sediment odor control was demonstrated to be environmentally friendly.
