济南2000台水空调三个月耗掉半个大明湖水量
  大量采水将会影响地下水资源,一个抽水井需要更多回灌井才能平衡
  近日,记者在山东省济南市周边采访中发现,当地不少居民为了防暑降温,在室内安装使用了一种叫“水空调”的节能产品。但记者调查发现,在表面上看起来环保、节能的消暑理念,在使用中却暗藏巨大的水资源浪费。
  “这种‘水空调’其工作原理就是把地下水抽上来,输送到水空调机中,经过风机盘管来达到制冷目的后,水经管道排掉。而水空调的售价仅相当于普通空调的三分之一,且更为省电,开一天一宿才用2元~3元的电费,制冷效果也非常理想。”一位使用水空调的居民向记者介绍,只需在自家房前打个井就能免费使用地下水,排出的水还能供周边商店、餐馆冰镇啤酒、西瓜等。
  记者在一位水空调用户家中了解到,一台水空调每分钟耗水35斤,每小时耗水1吨多。按一天开10个小时,一个夏天开3个月,记者进行了初步计算,一台水空调就要耗水900吨。而据水空调产品经销商们透露,济南周边的“水空调”数量不下2000台。如果一个夏天有2000台水空调在使用的话,耗水就高达180万吨。按济南大明湖容积120万立方米(合120万吨)计算,2000台水空调一个夏天要耗掉180万立方米水,相当于济南大明湖一个半的容量。
  济南市水利局水政监察支队负责人告诉记者,对于“水空调”浪费水的情况他们也有所了解,但按照规定只对济南市区城市公共供水管网覆盖范围以内进行监管,对私自打井乱采地表水的有权作出处理决定。而供水管网覆盖范围以外的还没有明确的规定。该负责人还表示,根据掌握的情况,这些“水空调”用户基本上处在城乡接合部,属于供水管网覆盖范围以外。这种水空调的正确使用方法是同时打两个水井,一个取水,一个回灌,但用户为了省下打井的钱,就只打一个水井,这样一来,排出的水只有白白地流掉。“尽管国家、省、市出台了相关的法律法规,但在计划用水、节约用水等方面仍存在规定不详细、操作性不强等问题。就济南市而言,亟须出台相关政策,扩大用水监管的范围和区域,以加强水资源的统一管理、开发与保护,促进水资源的优化配置与高效利用。”
  “如此大量采水将会对地下水资源产生很大的影响。”济南大学资源与环境学院水文水资源工程教授刑立亭说,地质结构的不同,地表水回灌地下水也不一样,有些地方一个抽水井需要两三个甚至更多回灌井才能平衡。如果将用过的水全部排掉,而没有加以回收利用,势必造成水资源的严重浪费,如果地表有垃圾,即使采用地表水回灌,也肯定会对地下水带来影响。(记者丛民 通讯员卢明)
