淤泥到底有没有清走？“两湖”治理最新进展来了……
<p style="text-align: center;" data-mpa-powered-by="yiban.io"><br/></p><p></p><section><p style="margin-bottom: 20px;color: rgb(51, 51, 51);font-size: 18px;letter-spacing: normal;white-space:

2px;"><span style="font-size: 17px;user-select: text !important;">近日，有市民反映，</span><span style="font-size: 17px;font-weight: 700;user-select: text !important;">“两湖”淤泥到底有没有清走？为什么还能看见湖中大片的黑色淤泥？怎么湖中还有许多机器在挖？为什么要用土把湖中的淤泥覆盖住？</span><span style="font-size: 17px;user-select: text !important;">记者通过咨询工程相关负责人，了解到清淤的工艺流程及进度情况。</span></span></p><p style="margin-bottom: 20px;color: rgb(51, 51, 51);font-size: 18px;letter-spacing: normal;white-space: normal;background-color: rgb(255, 255, 255);line-height: 2em;text-indent: 2em;font-family: Helvetica, Arial, sans-serif;user-select: text !important;"><span style="font-size: 17px;letter-spacing: 2px;"><span style="font-size: 17px;text-indent: 2em;user-select: text !important;">“两湖”内淤泥深度达1-2米，技术人员对不同区域进行多次检测，得出“两湖”湖底淤泥约20-40厘米的表层是受到严重污染的，其中磷氮含量严重超标及轻微重金属污染，导致“两湖”水质变差、发臭。</span><span style="font-size: 17px;font-weight: 700;text-indent: 2em;user-select: text !important;">清淤工程就是清除重污染的表层淤泥，首先是采取用水冲的方式稀释淤泥，然后将稀释的淤泥泵抽集中到一处进行脱水处理，最后由渣土车统一运走。</span><span style="font-size: 17px;text-indent: 2em;user-select: text !important;">据了解，两湖共清淤50余万方，对提升两湖的水质发挥了重要的作用。</span></span></p><p style="margin-bottom: 20px;color: rgb(51, 51, 51);font-size: 18px;letter-spacing: normal;white-space: normal;background-color:

17px;font-weight: 700;user-select: text !important;">对于清淤后保留下来的底层淤泥，采用原位修复的方式，</span><span style="font-size: 17px;user-select: text !important;">通过向底泥中添加环保友好型的复合材料，对有害污染物进行降解，降低底泥中营养盐和重金属的污染。与此同时，</span><span style="font-size: 17px;font-weight: 700;user-select: text !important;">为了恢复沿湖周边的水草，对沿湖周边的地形进行塑形，通过覆盖干净土壤，</span><span style="font-size: 17px;user-select: text !important;">将水深控制在3米以内，确保水草覆盖度达到水面的一半面积，同时使“两湖”周边向湖中心底部保持相对平缓，保证湖底不会因清淤和开挖留下坑洼。<br style="user-select: text !important;"/></span></span></p><p

!important;">我们所看见的湖中机器挖掘是在进行底泥原位修复和湖底塑形。</span><span style="letter-spacing: 2px;font-size: 17px;user-select: text !important;">上述工程的实施，将为彻底控制两湖的内外源污染和提升水质、构建“有水有草、有鱼有虾”的良好湖泊提供充足的保障。（刘邓玲 九江日报全媒记者

湖底淤泥原本就有着一种自我修复能力，当全部换成新土之后，至少需要三、五十年才能达到原有的生态平衡状况。
