水质监测系统选型时应注意的问题!

Time:2020-11-20     Author:北中科技   Read

      随着我国环境保护形势的不断发展和国内在线监测技术的日益成熟,为实现控制污染排放、提高环境质量的目标,各省市普遍开展了排污口在线监测。大大提高了环境管理水平。在这种背景下,国内外大量的在线监测仪器开始进入在线监测领域。如何安装在线监测仪器已成为排污单位关注的问题。本文简要介绍了在线水质仪表安装中的一些常见问题。


  一、特别注意数据传输网络,目前,每个省(市)都有不同程度的污染源在线监测网络,有的以有线传输为主,有的以无线传输为主。以河北省为例,河北省环境监测侧中心站建设的污染源在线监测网络由三部分组成:污染源到各市监测站的无线传输网络;各市监测侧站计算机局域网和河北省环境监测侧vsta卫星通信网。接入端具有模拟和数字两种传输方式。河北省环保厅明确规定,省环境监测中心站对“监测网”实行统一管理,组织区、市环境监测站做好在线监测仪器的比对和网络接入面收集,区、市环境监测站负责本区域污染源监测的网络管理。


  二、因此,用户应优先选用能通过国家计量机构认证的产品,并充分考虑网络仪表的本地监测网技术标准。必要时,可向当地省(市)监测部门咨询,了解政策要求和技术标准,确保安装的水质在线监测侧仪表能顺利接入在线监测网络


      三、对此,我们要特别注意避免在监测系统选择上出现几个误区:一是过分追求低价。为了省钱和处理环境检测,很多单位总是选择价格较低的仪器。然而,低成本的仪器在稳定性等方面往往难以令人满意,给以后的使用和维护带来许多麻烦。


  四、是盲目追求进口仪器。认为进口仪表性能优良,但事实上,进口仪表不一定适合机组的水质,或者没有完整的解决方案,造成不必要的浪费。这只是盲目的选择。一些单位在选型时有求同存异的心理,对仪器性能和自身水质没有详细了解,造成了系统固有的缺陷。


  总而言之,不同厂家的仪器在侧测原理、应用领域、现场测量范围、运行条件和成本、维护难度等方面存在很大差异。企业外的水质也大不相同,场地环境也不一样。用户必须综合考虑自身实际情况,选择适合自身水质和排放特点的在线仪表,不得盲目选择和安装。
