A regional water environment heavy metal monitoring system and operation method

Abstract

The invention discloses a regional water environment heavy metal monitoring system and an operating method. The regional water environment heavy metal monitoring system comprises a monitoring management system and a plurality of monitoring terminals, wherein the monitoring terminals are connected with the monitoring management system through general packet radio service (GPRS); a central processing unit of the monitoring management system is connected with a data transmitting and receiving module, a data analysis processing module, a database management module and a display or a user terminal; the data transmitting and receiving module is connected with a database storing global positioning system (GPS) information, information geographic information system (GIS) and correlated heavy metal concentration information detected by all the monitoring terminals; a master control module of each monitoring terminal comprises an embedded processor, a clock and a GPRS sub-module; a detection module comprises a temperature sensor and a heavy metal electrochemical sensor array. According to the operating method, the temperature and the heavy metal concentration, monitored by the monitoring terminals, of a water environment are transmitted to the monitoring management system to be stored and displayed, and are compared with standard values and historical data through the data analysis processing module; when the polluted water quality is determined or the concentration of certain heavy metal is suddenly increased to a higher level, an alarm is given. According to the regional water environment heavy metal monitoring system and the operating method, the pollution of a water body is timely found by real-time sampling analysis and dynamic monitoring; the monitoring terminals are simple to network and easy to expand.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and specifically relates to a regional water environment heavy metal monitoring system and an operation method. Background technique [0002] Water environment monitoring is an important means of water resources management and protection. [0003] With the development of society and industry, a large amount of domestic sewage and industrial wastewater are discharged into rivers and lakes, and rivers, lakes and seas in most parts of my country have been polluted by heavy metals to varying degrees. Heavy metal element pollution has become a major problem threatening the human living environment. The traditional water environment monitoring work is mainly based on manual sampling and laboratory instrument analysis, which has low monitoring frequency, small monitoring range, large sampling error, and poor real-time performance. Lack of technical means for real-time collection of he...

Problems solved by technology

The traditional water environment monitoring work is mainly based on manual sampling and laboratory instrument analysis, which has the disadvantages of low monitoring frequency, small monitoring range, large sampling error, and poor real-time performance.

Lack of technical means for real-time collection of heavy metal data in a wide range of water environment, and dynamic and static analysis, it is easy to miss the best time for timely prevention and control in the early stage of pollution
