An automatic sampling device and sampling method for water treatment adsorption experiments

Abstract

The invention discloses an automatic sampling device and a sampling method for a water treatment adsorption experiment. The device comprises a control system, a base, a fixing bracket, a four-way valve, a peristaltic pump, a three-way valve, a cleaning water bottle, an experiment sampling container and a rotating plate, wherein the cleaning water bottle, the experiment sampling container and the rotating plate are arranged on the base; the cleaning water bottle is connected with a first interface of the four-way valve through a cleaning pipe, a second interface of the four-way valve is connected with the experiment sampling container through a sampling pipe, a third interface of the four-way valve is connected with the first interface of the three-way valve through the peristaltic pump, and a fourth interface of the four-way valve is connected to air through an exhaust pipe; the three-way valve is connected with a waste water outlet pipe and a sampling water outlet pipe, respectively; the waste water outlet pipe is connected to a waste water collecting bottle in the rotating plate; and the sampling water outlet pipe is connected with a sampling bottle in the rotating plate. With the adoption of an actuate positioning technology, an automatic measuring technology, an automatic control technology and a batch-type sampling management system, the timing and quantitative automatic sampling is realized in a water treatment adsorption experiment process.

Description

technical field [0001] The invention relates to the technical field of automatic sampling, in particular to an automatic sampling device and a sampling method for water treatment adsorption experiments. Background technique [0002] With the development of industrialization and the improvement of human material living standards, the pollution of water environment has become a common problem in the world today. With the changes in the composition of water pollutants, the amount of pollutant discharge in some river basins is greater than the self-purification capacity of the environment, the trend of deterioration of the water ecological environment has not been effectively curbed, and the degree of damage to the water ecology in some areas is intensifying. To this end, it is necessary to effectively treat and purify the sewage to achieve a virtuous regeneration cycle of water resources. [0003] When a fluid is in contact with a porous solid, one or more components in the fl...
