Problems solved by technology

Rainfall is regional. Researchers cannot accurately know the actual rainfall situation of the polluted site according to the rainfall situation in their own area. The existing rain station is not necessarily within the scope of the polluted site. there is inconsistency
These problems lead to the blindness and cumbersomeness of sampling, and reduce the scientificity and effectiveness of the research on the migration and transformation of pollutants in soil and groundwater.

Abstract

The invention relates to a groundwater resource on-line monitoring system and a detection method of the groundwater resource on-line monitoring system. The main control system, data receiving device and on-line monitor are installed in the groundwater resource monitoring area. Multiple on-line monitors are installed in the groundwater resource monitoring area, at least 3 on-line monitors. The data receiving device receives the data information sent by the on-line monitor. It is transmitted to the main control system, and the main control system processes the received data information, and sends instructions to the online monitor for real-time monitoring. It consists of a transmission device, a measuring instrument, a protective cover, a rainwater metering device, a data transmission device and a groundwater observation well, and an online monitor is installed on each groundwater observation well. The invention has scientific design, reasonable and compact structure, simple and convenient operation, detachable equipment, convenient disassembly and assembly, easy portability, and completes monitoring of groundwater level and water quality after rainfall, which is efficient and real-time, and reduces monitoring errors.

Description

technical field [0001] The invention relates to a system and a detection method for monitoring groundwater resources, in particular to an online monitoring system for groundwater resources and a detection method for the online monitoring system for groundwater resources. Background technique [0002] my country is a country seriously short of water resources. As an important part of water resources, groundwater is an important source of water supply and an important support for ecosystems. According to the survey, 65% of domestic water, 50% of industrial water and 33% of agricultural irrigation water in northern my country come from groundwater. With the rapid development of industrial production and the continuous expansion of urban scale, industrial sewage residues, chemical fertilizers, pesticides and sewage irrigation have caused serious pollution to soil and groundwater. The soil has a certain purification ability for external pollutants, but the purification ability o...
