北方缓流水体水质在线自动监测系统采样口的设计思考

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。

Idea of design on sampling place of on-line water quality monitoring system of northern slow-moving water body

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.
