Title:
WATER SAMPLE PRETREATMENT DEVICE, WATER SAMPLE PRETREATMENT SYSTEM, AND WATER SAMPLE PRETREATMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2021/254380
Kind Code:
A1
Abstract:
A water sample pretreatment device, a water sample pretreatment system, and a water sample pretreatment method. The water sample pretreatment device comprises a water tank (10) for static settling of source water, wherein the water tank (10) is in communication with a source water supply device (20); the water tank (10) is further in communication with a water distribution device (30), and the water distribution device (30) is used for the distribution of a supernatant from the water tank (10) into a testing instrument (50); and the source water supply device (20) and the water distribution device (30) are respectively connected to a control device. The water tank (10) is internally provided with a turbidity measurement device (60) for real-time measurement of the turbidity of the source water or the turbidity of the supernatant, and the turbidity measurement device (60) is connected to the control device. The water distribution device (30) is in communication with a secondary treatment device (70), wherein the secondary treatment device (70) is used for pretreatment of the supernatant distributed by the water distribution device (30) to allow the supernatant distributed into the testing instrument (50) to have a turbidity value equal to or less than a preset system threshold, and the secondary treatment device (70) is connected to the control device.
