Abstract:
The present invention discloses a device for measuring adsorption/desorption of contaminants onto surface bed sediments and a method of using the device. The measurement device includes a sediment sample disc, a sample holder, a reaction cylinder, a liquid collection cylinder, and a liquid circulating member from inside to outside, the liquid circulating member consisting of rubber pipes and a peristaltic pump. According to the method of using the device for measuring the adsorption/desorption of contaminants onto surface bed sediments, the full contact of bed sediments with pore water and the full exchange of overlying water with pore water are realized through liquid circulation without changing the arrangement modes of the bed sediments; any thickness of bed sediments can be performed on experiments, particularly for thin-layer bed sediments; and natural permeation and accelerated permeation of pore water through bed sediments can be switched simply by adjusting the flow rates of the peristaltic pump and by opening/closing of vent holes. Adsorption characteristic parameters obtained through the device and the method provide, for water quality models, data support which conforms to the natural existing condition of bed sediments and is more scientific and reasonable, and the device and the method achieve significant environmental benefits.

Claim (Index 2):
The device for measuring the adsorption/desorption characteristic of surface bed sediments on contaminants according to  claim 1 , wherein the diameter of an opening on a bottom surface of the reaction cylinder is smaller than the diameter of a bottom surface of the sample holder and the diameter of the bottom surface of the sample holder is smaller than the diameter of an opening on a top surface of the reaction cylinder, such that the bottom of the reaction cylinder supports the sample holder and is closely connected to the bottom of the sample holder, and thereby, the liquid in the reaction cylinder completely permeates into the liquid collection cylinder through a bottom of the sediment sample disc.
