污染源和环境水质监测仪器
Pollution sources and environmental water quality monitoring instruments
(1) 污染源在线监测仪器
(1) Online monitoring instruments for pollution sources
污染物排放的总量监测要求浓度与流量同步连续监测，在线测流和比例采样是总量监测的基本技术手段，对于重点污染源还需要配备在线监测仪器。
The total amount monitoring of pollutant emissions requires synchronous and continuous monitoring of concentration and flow rate. Online flow measurement and proportional sampling are the basic technical means of total amount monitoring. For key pollution sources, online monitoring instruments are also required.
(2) 流量计
(2) Flowmeter
用于规范化的明渠污水排放口流量的在线连续监测仪器。
An online continuous monitoring instrument for the flow rate of standardized open channel sewage discharge outlets.
(3)自动采样器
(3) Automatic sampler
用于污染源排放口具有流量比例和时间比例两种方式的在线自动采样装置。
An online automatic sampling device with two methods of flow ratio and time ratio for pollution source discharge outlets.
(4) 在线监测仪器
(4) Online monitoring instruments
用于工业污染源或污水排放口的在线测分析仪器。监测主要项目有：COD、TOC、UV、NH4、NO3-N、氰化物、挥发酚、矿物油、pH等，应具有自动校正和自动冲洗管路功能。
An online measurement and analysis instrument used for industrial pollution sources or sewage discharge outlets. The main monitoring items include COD, TOC, UV, NH4, NO3-N, cyanide, volatile phenols, mineral oil, pH, etc. It should have automatic calibration and automatic flushing pipeline functions.
(5) 环境水质自动监测仪器
(5) Automatic monitoring instrument for environmental water quality
用于地表水环境质量指标的在线自动监测仪器。水质自动监测项目分为水质常规五参数和其它项目，水质常规五参数包括温度、pH、溶解氧（DO）、电导率和浊度，其它项目包括高锰酸盐指数、总有机碳（TOC）、总氮（TN）、总磷（TP）及氨氮（NH3-N）。
An online automatic monitoring instrument for surface water environmental quality indicators. The automatic water quality monitoring project is divided into five conventional water quality parameters and other projects. The five conventional water quality parameters include temperature, pH, dissolved oxygen (DO), conductivity, and turbidity. Other projects include permanganate index, total organic carbon (TOC), total nitrogen (TN), total phosphorus (TP), and ammonia nitrogen (NH3-N).
(6) 总有机碳（TOC）测定仪
(6) Total organic carbon (TOC) analyzer
总有机碳（TOC）是反应水体有机物含量的指标，可用于污染源或地表水的监测。
Total organic carbon (TOC) is an indicator of the organic matter content in water, which can be used for monitoring pollution sources or surface water.
