在线检测医疗污水中余氯浓度的设计及实现

Measuring the Concentration of Residual Chlorine in hospital Sewage On-line by a Method which Base on the Substantial Absorption Spectrum

国家要求医疗污水需经处理后方可排放,目前国内大部分医院采用二氧化氯处理医疗污水,检查二氧化氯消毒的效果及是否产生二次污染是通过检测处理后的废水中余氯的含量来判定的。由于污水中成分较为复杂,在线检测废水中余氯的问题始终困扰着人们。本文介绍了一种在线检测医疗废水中余氯浓度的设计,该设计是借助试剂发色可见波长范围内光吸收的原理检测医疗废水中的余氯,以单片机为主控制器,控制系统复位机构实现在线连续检测、信息显示及远传、废水达标排放等。该设计已完成,经实验,检测结果与常规检测余氯的结果基本一致。

The article introduces a design about measuring the concentration of chlorine residue in iatrical sewage on-line. The design base on a method of substantial absorption spectrum. The article lays emphasis on the realization of measure and return system along with the design of measure software. Through experimental examination, its result corresponds basically with the result of general chlorine residue detection. The design can solve the problem that the mode of iatrical sewage on-line detection is not deficient.
