TOC is a set of management concepts and principles about making improvements and how to best implement them. It can help companies identify the constraints that exist in the process of achieving their goals, which TOC refers to as "constraints", and further point out how to implement necessary improvements to eliminate these constraints one by one, in order to more effectively achieve their corporate goals.
The nature or quality of wastewater is a comprehensive characteristic exhibited by a complex system composed of water and various impurities, which is important in engineering practice The unit of acute toxicity is usually expressed as the half lethal concentration (LD50) of the toxic substance or wastewater that causes 50% death of the test organism within a specific exposure time.

从理论上对化工污水TOC与COD_a的相关性进行了分析,对在实际工作中测得的TOC和COD_a数据进行了回归分析。结果表明,化工污水的TOC和COD_a之间有着良好的相关性。在一定条件下,利用回归方程可以从测得的TOC值推算出COD_a值,或者从COD_a值推算出TOC值。因此,TOC值可以用来表示有机废水的污染程度,也可做为有机污染物的一个控制指标。

Theoretical analysis was conducted on the correlation between TOC and COD_a in chemical wastewater, and regression analysis was performed on the TOC and COD_a data measured in practical work. The results indicate a good correlation between TOC and COD_a in chemical wastewater. Under certain conditions, the COD_a value can be calculated from the measured TOC value using regression equations, or the TOC value can be calculated from the COD_a value. Therefore, TOC value can be used to indicate the degree of pollution in organic wastewater and can also be used as a control indicator for organic pollutants.
There is a good correlation [Z, 31]. Preface: In the same wastewater sample, if there is no other interference and the oxidation is complete, the measured TOC value is directly proportional to the COD value. For a long time, the degree of organic matter decay in water bodies has been evaluated as COD-KTOC. Since C Oz-CO is calculated, the classic methods are used to determine COD and BOD. BOD/5-32/12=2.667.
Application scope

工作原理
水样通过进样口进入仪器后由分流器分成相等的两份,其中一份通过延迟线圈4,进入二氧化碳传感器3检测TIC,另一份通过镀有二氧化钛的螺旋石英玻璃管1,并在紫外灯2的照射下将水中有机物催化分解为二氧化碳,进入电导率传感器3检测 TC。总有机碳可通过这个差值计算得到:TOC = TC–TIC,最后废液通过蠕动泵5,从排液管流出。
离线检测
离线检测时,仪器可从样品瓶或其它没有压力的容器直接取样。仪器管路冲洗和仪器校准应在离线状态操作。若样品中有不可溶性微粒,应经过滤膜(孔径60μm或更小)过滤后进入仪器,以防止样品中的微粒阻塞仪器。仪器的进样管为1/16英寸的Teflon管,经蠕动泵抽进管路中的水样流速约为0.5 ml/min。
系统组成
TOC分析仪的组成包括以下7个主要部分:
① 在线检测装置(在线型仪器配备)
② 样品蠕动泵
③ 分流器
④ 氧化反应器
⑤ 二氧化碳传感器
⑥ 微处理控制器和电子线路板
⑦ 输出接口
分流器
水样进入仪器后分成相同流量的两路,其中一路通过延迟线圈进入二氧化碳传感器,检测TIC,另一路通过氧化反应器利用紫外灯(UV灯)加二氧化钛薄膜光催化氧化作用将有机物分解为二氧化碳,进入二氧化碳传感器检测TC。总有机碳可通过这个差值计算得到:TOC = TC–TIC。
working principle
After entering the instrument through the injection port, the water sample is divided into two equal parts by the splitter. One part passes through the delay coil 4 and enters the carbon dioxide sensor 3 to detect TIC, while the other part passes through the spiral quartz glass tube 1 coated with titanium dioxide and catalyzes the decomposition of organic matter in the water into carbon dioxide under the irradiation of the ultraviolet lamp 2, and enters the conductivity sensor 3 to detect TC. The total organic carbon can be calculated by this difference: TOC=TC-TIC. Finally, the waste liquid flows out of the discharge pipe through peristaltic pump 5.
Offline detection
When conducting offline testing, the instrument can directly sample from sample bottles or other containers without pressure. Instrument pipeline flushing and instrument calibration should be operated offline. If there are insoluble particles in the sample, they should be filtered through a filter membrane (with a pore size of 60μm or smaller) before entering the instrument to prevent particles from blocking the instrument. The injection tube of the instrument is a 1/16 inch Teflon tube, and the flow rate of the water sample drawn into the pipeline by a peristaltic pump is about 0.5 ml/min.
system composition
The composition of TOC analyzer includes the following 7 main parts:
①Online detection device (equipped with online instruments)
②Sample peristaltic pump
③Diverter
④Oxidation reactor
⑤Carbon dioxide sensor
⑥Microprocessor controllers and electronic circuit boards
⑦Output interface
Diverter
After entering the instrument, the water sample is divided into two equal flow paths. One path enters the carbon dioxide sensor through a delay coil to detect TIC, while the other path uses an oxidation reactor to decompose organic matter into carbon dioxide through the photocatalytic oxidation of a titanium dioxide film using a ultraviolet lamp (UV lamp), and enters the carbon dioxide sensor to detect TC. The total organic carbon can be calculated by this difference: TOC=TC–TIC.
