A closed monitoring system and method for observation wells of high water level groundwater head and water quality

Abstract

The invention discloses an observation well closed monitoring system and method of the high water level underground water head and quality. The system comprises a wellhead air pressure closing unit, a detection sensing unit and a data transmission unit, wherein the wellhead air pressure closing unit comprises a seal box arranged at an observation wellhead; the seal box is used for isolating air inside the well from air outside the well; the detection sensing unit comprises an air pressure sensing module arranged in the seal box and a water temperature and quality sensing module arranged in the well; the data transmission unit comprises a plurality of data collection modules for collecting the air pressure and water temperature and quality parameters acquired by the detection sensing unit and achieving real-time monitoring of the parameters in the observation well. The system and the method have the beneficial effects that the problem that water continuously gushes from the high water level underground water observation wellhead in the wet season, thus causing water resource waste is solved; meanwhile, closed monitoring plays a positive role in preventing water resource pollution.

Description

technical field [0001] The invention relates to a closed monitoring system and method for observation wells of high water level groundwater head and water quality. Background technique [0002] For areas with high groundwater head, such as Jinan, Jining, Tai'an, Linyi in Shandong, Xingtai in Hebei, Yangquan in Shanxi, Linfen in Shanxi, etc., the groundwater head in these areas is generally higher than the ground, and with the change of seasons, the height of the water head is sometimes high and sometimes low . For the observation of water level and water quality in these special areas, traditional long-term groundwater observation wells are generally used. These observation wells are generally open, and the head height of groundwater, as well as its physical and chemical properties are obtained through manual collection. [0003] For these special areas, the use of this traditional observation method mainly brings three problems: [0004] First of all, for the high water l...

Problems solved by technology

[0008] In order to solve the above problems, the present invention proposes a closed monitoring system and method for observation wells with high water level groundwater head and water quality. Groundwater is not polluted, and the data obtained are continuous, so it is of great significance to apply this method to long-term observation wells of groundwater
