Long-distance online detection method and long-distance online measuring device for multiple parameters of underground water

Abstract

The invention discloses a long-distance online detection method and a long-distance online measuring device for multiple parameters of underground water. A control signal is sent to an on-site measuring instrument through a remote control instrument to rouse the on-site measuring instrument; in the on-site measuring instrument, an underground water sample drawing and cleaning device is used for drawing underground water to be tested, an underground water quality multiparameter detection device is used for detecting the underground water to be tested, detection data are sent back to the remote control instrument through GSM (global system for mobile communication), finally, the underground water sample drawing and cleaning device is used for cleaning a water sample passage therein so as to perform detection of the underground water to be tested for next time, thereby realizing long-distance online detection for the multiple parameters of the underground water. The method and device can be used for performing long-distance detection on chemical oxygen demand in the underground water quality and on substances such as nitrate ions and chromium ions as well as turbidity degree in the underground water, the disadvantage that traditional chemical detection causes secondary pollution to the environment is avoided, the period of underground water quality detection is shortened, the technological process of the underground water quality detection is simplified, and the fast and efficient detection requirement is met.

Description

technical field [0001] The invention relates to a parameter detection method and device, in particular to a remote groundwater multi-parameter online detection method and a measurement device. technical background [0002] With the rapid economic development and the acceleration of urbanization, groundwater pollution incidents occur frequently. How to quickly and effectively detect and judge the status of groundwater pollution has become the key to solving this problem. Among them, groundwater quality detection technology is the guarantee to solve this problem. . At present, in the field of groundwater quality testing in my country, manual on-site sampling and laboratory instrument analysis are mostly used as the main methods. There are defects such as large sampling errors, long testing cycles, complicated operations, and inability to reflect changes in water pollution in a timely manner. The detection and evaluation of groundwater pollution needs. Contents of the inventi...
