Self-content turbidity sensor has its own battery and monitors water quality independently. It can be integrated on the water quality meter or buoy. 自容式浊度传感器自带电源,可独立完成浊度值的测量,也可集成在水质监测仪或者浮标上。
This article introduces the design characteristics, test result and applied situation in monitoring injected water quality in oilfield of BG-1 type microporous membrane filtration meter. 介绍了BG-1型微孔薄膜过滤仪的设计特点、测试结果及在油田注入水水质监测中的应用情况。
But there also appeared some problems due to unsoundness, such as lack of emphasis on water quality test resulting in mass criticism, and clashes with end-users dissatisfied with forcing them to install water meter. 但是由于公司的不完善,也出现了一些问题,如对水质化验不重视遭到了人们的批评,强制用户安设水表而导致与用户的冲突。
The water quality indexes, including total nitrogen ( TN ), total phosphorus ( TP ), the chemical oxygen demand ( CODcr ) and pH value, were respectively determined by alkaline potassium persulphate digestion-UV spectrophotometric method, ammonium molybdate spectrophotometric method, dichromate method and pH meter. 分别用碱性过硫酸钾消解紫外分光光度法、比色法、重铬酸盐法测定了灌溉前后灌溉水水质指标总氮、总磷、化学需氧量(CODcr),同时测试pH值。
