Abstract

The invention which relates to an analogue device for researches on water-deposit interface heavy metal release and form change under high water level conditions belongs to the fields of the environmental science and the environmental engineering. The device can be applied to the construction and deposit pollution after pollution discharge, of reservoirs in northern China, and the device is used for the researches on the influences of the change physical and chemical conditions (DO, ORP and pH) on the deposit-water interface heavy metal release and forms of heavy metals in the deposit under the high water level conditions. The heavy metal release risk under waterlogged conditions can be realized. The change of the forms of the heavy metals in the deposit after pollution under the waterlogged conditions, and influence factors thereof are further analyzed and researched, so influences caused by the basin deposit quality change and the hydrological condition change are subjected to accurate and continuous online monitoring.

Description

Technical field:

[0001] The invention relates to a simulation device suitable for studying the release and form change of heavy metals at the water-sediment interface under high water level conditions, belonging to the fields of environmental science and environmental engineering. Background technique:

[0002] In the northern part of my country, economic development and population increase have caused a large amount of pollutant discharge, causing serious water pollution. At the same time, in order to maximize the use of limited water resources, many artificial gates and dams have been built, which also block the continuity of rivers, weaken the self-purification function of river-type wetlands, and cause the water environment and water ecology to continue to deteriorate. Pollutants in water bodies, especially heavy metals, are easy to accumulate in suspended particles. As suspended particles settle in river wetlands, heavy metals and other pollutants enter the river water ...
