Bottom sediment pollutant release rate measuring device

Abstract

The invention belongs to a bottom sediment pollutant release rate measuring device in the field of municipal engineering. According to the technical scheme, the bottom sediment pollutant release ratemeasuring device comprises an experimental device and a bottom sediment sampling device, the main structure of the experimental device is a cylinder body, a plurality of bottom sediment storage tanksare arranged below a bottom platform at the lower part of the cylinder body, and the size of the bottom sediment storage tanks is matched with the bottom of the bottom sediment sampling device; the cylinder body is provided with a circulating water loop for discharging water and feeding water; an upper-layer curtain and a lower-layer curtain which can be stretched and rolled up in the horizontal direction are respectively arranged above the bottom sediment storage tank in the tank body; the bottom sediment sampling device can be vertically inserted into the bottom sediment storage tank, and the bottom sediment sampling tank is provided with a movable sealing inclined bottom plate. According to the method, the problems existing in the current bottom sediment pollutant release rate measurement are better solved, and the on-site bottom sediment pollutant release rate of the water body is reduced. The bottom sediment sampling device matched with the experimental device is arranged, the protection work on the existing hierarchical structure of bottom mud in the bottom sediment placing process and a device water filling process is emphasized, and the release rate of water body on-site bottom sediment pollutants is well reduced.

Description

Technical field[0001]The invention belongs to the field of municipal engineering, and specifically relates to a device for measuring the release rate of sediment pollutants.Background technique[0002]In the comprehensive improvement of urban water environment, the release of sediment pollutants in black and smelly water bodies and large areas of lakes occupy a large proportion of the pollution load. A reasonable assessment of the release rate of sediment pollutants and the main influencing factors of the release rate can provide reasonable and evidence-based suggestions for the treatment of sediment in the water environment.[0003]However, in the process of measuring the release rate of sediment pollutants, no attention was paid to the protection and restoration of the hierarchical structure of the sediment. The repeated mixing and agitation of the sampled sediments made the laboratory sediment pollutant release rate determination work. , Pore layer, overlying water layer and other hi...
