摘要
以DO作为水体的污染指标来判定水质类别存在一定的缺陷,北方缓流水体在不同季节常存在不同的DO分层现象,现设在河床底以上0.5米处的自动监测采样口设计缺少科学性。在叙述缓流水体DO特点的同时,介绍一种新的水质在线自动监测采样口的方案,便于类似水体水质自动监测设计中借鉴。
There is some limitation if we classify water quality using DO as pollution indication of water, in Northern area, different layered DO in slow-moving water body often exists in different season, there is a lack of science if we set auto-monitoring sampling place on or above 0.5 meter distance from river bed. The article introduce DO attribute in slow-moving water, at the same time, introduce a new idea about on-line monitoring sampling place of water so as to provide reference for water-quality auto-monitoring design of similar water body.
