“zji zji zji日本”南水北调水源zji zji zji日本地如何确保一泓清水 来看丹江口"空天地水"全方位保护

  湖北zji zji zji日本省丹江口市是南水北调中线工程zji zji zji日本核心水源地,汩汩清水从这里出发,穿越中原,一路向北,直抵京津腹地。千里调水,水质是焦点。丹江口是如何加强水源地保护,确保一泓清水永续北上,来看记者的探访。

  丹江口2313公里长的库岸线,岸线曲折、河汊众多,队员们每天在辖区水域要开展3次以上的巡查。

  湖北省丹江口市农业综合执法大队大队长熊罡:库区面积太大,以前没有科技手段的时候就靠一个中队几个人,一两个星期这个辖区都转不完。

  熊罡告诉记者,过去单靠人力监管,投入大效率也差,但如今在丹江口,这一库碧水已经装起了“智慧大脑”。

  20台返巢式无人机、260个环库岸线高清摄像头和高空卫星织成一张“天网”,把污水偷排、非法垂钓、危化品车辆运输等“风吹草动”看得清清楚楚。地下雨污管网内的监测仪实时保持警惕,一旦出现跑冒滴漏,管道机器人可以精准探查、及时修补。

  记者随机点开了一家重点排污企业,进水量、出水量、排污口酸碱值等信息实时跳动。通过对比数据,算法能够自动研判出企业是否偷排污水,并采取措施整治。

  丹江口市水库水质安全保障指挥中心主任 张岩:这是汉江进入丹阳口水库的国控断面,截至目前Ⅰ类水是148天,从十堰市流出的时候,Ⅰ类水是253天。

  但是只盯着水库还不够,丹江口大小河流、支沟共有320多条,小河清大河才能干净,小流域综合治理让丹江口水库的环境治理把住了根。

  浪河是汇入丹江口水库的最大支流,以前一到夏天,绿油油的蓝藻水华就出现了。

  中国科学院水生生物研究所研究员 张学治:整个水生态的修复是个硬骨头。去年一年和今年一年,我们在浪河住着,跑了整个流域。

  张学治告诉记者,要追溯污染源,他们就要追着雨跑,从地表径流中发现端倪。

  正是基于这脚底板走出来的调研,他和团队完成了《丹江口市浪河小流域水环境综合治理方案》。在这支科研小队的帮助下,蓝藻水华拦截、打捞、沉降、生长抑制等项目同时推进,2024年以来,浪河再没出现过水华现象,平均水质也稳定在了Ⅱ类以上。

  如今,丹江口市重点区域及纳入小流域治理范围内的水冲式厕所改造率达到100%,垃圾和污水收集处理率也达到了100%。今年前三季度,丹江口市水经济相关产业实现产值124.1亿元。一泓清水是保护的结果,更成了发展的动力。
