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 1):
A device for measuring the adsorption/desorption characteristic of surface bed sediments on contaminants, comprising 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, wherein the liquid collection cylinder is a cylinder with the reaction cylinder in an upper part, an upper surface of the reaction cylinder is an opening on an upper surface of the liquid collection cylinder and an outer wall of the reaction cylinder is an inner wall of the liquid collection cylinder; the reaction cylinder has an opening on the bottom and is suspended in the liquid collection cylinder, a distance from the bottom of the reaction cylinder to the bottom of the liquid collection cylinder is greater than a half of the overall height of the liquid collection cylinder, and vent holes are provided on a wall of the reaction cylinder; the sample holder is fitted in the reaction cylinder and has a frame structure, the bottom of the sample holder is hollow-out and is connected to the opening on the bottom of the reaction cylinder; the sediment sample disc is placed on the sample holder, and is a hollow cylinder with its diameter being equal to the diameter of the bottom of the sample holder; two rubber pipes extend from the peristaltic pump, one of the two rubber pipes is connected to the bottom of the liquid collection cylinder, and the other one of the two rubber pipes is connected to the wall of the reaction cylinder and is closely attached to and fixed on the wall; liquid in an upper part of the reaction cylinder passes through a sediment sample and enters a lower part of the liquid collection cylinder, while the liquid in the liquid collection cylinder enters the upper part of the reaction cylinder under the power provided by the peristaltic pump, thus forming a water circulation in the device.
