In-situ monitor device for synchronously analyzing physico-chemical property of hyporheic zone and using method thereof

Abstract

The invention discloses an in-situ monitor device for synchronously analyzing the physico-chemical property of a hyporheic zone and a using method thereof. The device mainly comprises a cuboid main body, wherein a tip part for inserting into the hyporheic zone is arranged at the lower end of the main body, a plurality of interstitial water passive sampling chambers are distributed inside the mainbody along the height direction, and sampling openings communicated with the interstitial water passive sampling chambers are respectively formed in front and rear surfaces of the main body; the sampling openings are covered with dialysis membranes which are compressed through a grating plate; a plurality of sensor fixing grooves are arranged above the interstitial water passive sampling chambers,monitoring sensors are embedded in the sensor fixing grooves, sensing probes of the monitoring sensors extend into the interstitial water passive sampling chambers, and signal cables are connected with a data processing module through cable slots; and a storage battery module is used for supplying electricity to the data processing module and the monitoring sensors, and the data processing moduleand the storage battery module are positioned at the top inside the main body. The device can be used for synchronously and nondestructively monitoring physical and chemical properties of the hyporheic zone, and has the advantages of accurate monitor and convenience in use.

Description

Technical field [0001] The invention relates to an in-situ monitoring device for synchronously analyzing the physical and chemical properties of an undercurrent zone and a use method thereof, belonging to the field of in-situ monitoring of water environment. Background technique [0002] The undercurrent zone is a transition zone where the river surface water and groundwater dynamically interact with each other. Undercurrent exchanges are frequent and material circulation is active. It is the main place for the exchange, metabolism and storage of particulates and solutes in the river. It is known as the "liver" of the river and is in the river ecosystem. It plays an indispensable role in the process of balance and stability. At present, the underflow area of ​​rivers has become a hot area of ​​research at home and abroad. [0003] The environment of river surface water and groundwater is very different, and the physical and chemical properties of the underflow zone often show grad...
