秦淮河:清水能否长驻
日前,随着南京九华山隧道围堰工程的结束,[url=http://www.sg560.com/products/c7688/njxingde_31879786.html]安徽风冷式冷水机[/url],南京市有关部门恢复了对内秦淮河的放水冲洗。每天近20万吨的清水注入,使内秦淮河的水质大为改善。
而用清水冲洗的方式来治污,是不是奢侈了一点?不要说西部还有许多地区因为干旱,一家人每日只能定量用水。北京今年就定下节水计划,有消息说,该市的水价几乎要翻上一倍。即使在水乡江南,每天近20万吨清水也是不小的量。问题还不在这里,[url=http://www.cntrades.com/b2b/njxingdejx/sell/itemid-109120714.html]天津冷水机厂家[/url],如此大规模的清水冲刷后,秦淮河能否保持住清洁度,是个问题。
今年上半年,南京市环保局的检测结果表明,外秦淮河和秦淮新河江宁段水质劣于上年同期,有机污染加重。主要超标指标氨氮、生化需氧量同比上升幅度在145%—275%。今年7月,秦淮河忽然成了“黑水河”,大煞风景的黑水和臭味,让来夫子庙游玩的游客们兴致大减。造成这一情况的主要原因包括:玄武湖隧道施工,中断了内秦淮河引水补水;外秦淮河整治工程包括截污工程尚在实施过程中,污水排放仍存在;城市扩张过程中,城郊结合部的生活污水尚未截流,[url=http://njxdjxgi.cn.makepolo.com/product/100924679296.html]油用电加热器价格[/url],生活污水还在外排。
因此,治理秦淮河是个系统工程,其中,[url=http://www.china.cn/qthuanbaoshebei/4003778507.html]无锡导热油电加热[/url],最重要的是市民的环保意识。目前,沿内秦淮河一带,住宅、餐饮、宾馆林立,他们保护河流生态环境有义不容辞的责任。
