Description

一种不断水管道生物膜及生长环采集装置 技术领域
本发明涉及饮用水技术领域，具体为一种不断水管道生物膜及生长环采集装置。
 背景技术
供水管网中的腐蚀老化是一个非常普遍的现象。而管网的老化以及腐蚀往往会在管道内部形成生长环以及生物膜，这些管网运行后的衍生产物严重的影响管道水质，生长环的增长也会降低管道口径减少过水断面增加能耗，因此如何有效的监控这些风险点，采集数据量化其变化机理成为供水行业关注的焦点。
 技术问题
而管道长期埋藏在地下，如果通过截管采集数据，一是无法进行线性监控生长环及生物膜形成过程，二是施工不便且宜破坏样品，需要断管并水平切割采集样品，并重新放管以保障管网顺利运行，三是如果断水采样难免会对一些支状管的供水产生影响。
    因此极需一种装置解决上述采样不便问题，同时又能对单一管道生长环及生物膜的情况进行连续监测。
