南通北濠新村景观水治理

CREATE_TIME:2019-01-08 VIEWS:479

位于南通北濠新村旁大约700-800m的濠河段,由于周围市民长期将大量的生活垃圾直接丢弃到河里,导致河水流通不畅,水体发黑、发臭,透明度极低,经检测其水质为劣五类。南通美联环保有限公司于2004年8月承接了该河段7000m3的修复工作。有关技术人员在对河水进行了仔细的检测后,制定了投放利蒙LLMO S-1、N-1产品的治理计划。利用兼氧生物菌去除水中氨氮及亚硝酸盐,最终转化为氮气释放,利用异养生物菌分解大分子有机物,将有机碳最终转化为二氧化碳和水,经过两次利蒙LLMO投放后,河水氨氮含量由19.1mg/L降到了7.0mg/L,河水的能见度也上升到了50cm。

如今,河畔杨柳依依,闲暇的市民悠闲的在岸边散步,微风吹起了轻轻的涟漪,鱼儿在湖中嬉戏。周围的市民情不自禁的感慨:“这样的河水才是真正的景观水呀!”
