The preprocess method of the device includes the following steps：
S1：It checks and closes the first normally closed solenoid valve (11), the valve on the second normally closed solenoid valve (24) and blow-off pipe (8), keep away
Exempt from that the phenomenon of leakage occurs；
S2：The valve on water inlet pipe (6) is opened, the water sample that needs detect is made to first pass through filter chamber (3) filtering, in filter chamber (3)
Chamber is equipped with the filter device (7) horizontal by 45 degree, and filter device (7) will need to detect the larger suspension in water sample
Object, silt and impurity are directly stopped in top left, and the water sample detected to needs is tentatively filtered；
S3：Detection water sample after preliminary filtering flows into sampler chamber in filter chamber's (3) intracavity bottom and by ceramic filter plate (5)
(4) in, ceramic filter plate (5) filters the fine impurities in the water sample for needing to detect again, avoids influencing testing result；
S4：Synchronous with S3 steps is the valve opened on blow-off pipe (8), and discharge in time accumulates in filter device (7) top left
Larger suspended matter, the impurity such as silt at end, avoid filter device (7) from being blocked by impurity, effectively improve filter efficiency；
S5：The sampling pipe (18) for being arranged on right end at the top of sampler chamber (4) is acquired the water sample after clarification detection, and sampling pipe
(18) bottom is equipped with filter sheath (19), and further filtering needs the water sample detected, effectively improves the accuracy of detection data；
S6：Control valve (22) and the second normally closed solenoid valve (24) are opened, discharges the water sample in sampler chamber (4), return duct (23)
It is connected with recoil water pipe (9), using the water sample discharged in sampler chamber (4) through rotary nozzle (10) to filter hole (72) and filter chamber
(3) inner wall is rinsed, and is not only improved the filter efficiency of filter hole (72), is also effectively prevented filter chamber (3) inner wall and corroded,
The more efficient utilization rate for improving water resource；
S7：Synchronous with S6 steps is to start motor (12), and motor (12), which drives agitating vane (15) and scrapes miscellaneous device (17), to be turned
Dynamic, agitating vane (15) stirs the solid matter for being deposited on sampler chamber (4) intracavity bottom, and discharges pre- place by drainpipe (21)
It manages case (1) outside, scrapes miscellaneous device (17) removing and stick the impurity on sampler chamber (4) inner wall, not only avoid sticking in sampler chamber (4) inner wall
On impurity caused by detection error, also effectively increase the service life of the device.
