水质监测常规参数有哪些?应如何取样?

Time:2020-11-24     Author:北中科技   Read

       随着社会发展的不断进步,环境的污染受到了我们大家的关注!其中水环境为重要关注点之一。因此水质监测就成为了我们的必修课!那么监测的一些常规参数主要有哪些呢?又应该如何去取样呢?本章水质在线监测仪厂家来和大家一起了解相关知识!


  水质监测五参数:pH、温度、溶氧、电导率、浊度。


  各地区应对地下水水质进行定期检测。检验方法,按我国标准执行。


  各地地下水监测部门,应在不同质量类别的地下水域设立监测点进行水质监测,监测频率不得少于每年二次(丰、枯水期)。


  监测项目为:pH、COD、BOD、SS、氨氮、硝酸盐、亚硝酸盐、挥发性酚类、砷、汞、铬(六价)、总硬度、铅、镉、铁、锰、溶解性总固体、高锰酸盐指数、大肠菌群,以及反映本地区主要水质问题的其它项目。


  不同项目涉及到的水质在线监测仪也会有所差异,分别有:COD在线分析仪,氨氮在线监测仪,水中重金属在线监测仪,水质大肠杆菌在线分析仪等等!

       那么在水质监测过程中如何取样?


  仪器内部取样:采用注射泵,注射泵与蠕动泵相比特点是寿命长,不存在像泵管等这样的易老化部件,注射泵使用寿命可伴随仪器终生。


  仪器外部取样:分别提供潜水泵和自吸泵两种方式,一般潜水泵方式用于水样点与地面落差过大(通常超过2米)的情况,自吸泵用于水样点与地面落差少于2米的情况。
