The second power pump 130 then pumps the supernatant, which is fed into the filter housing 141 from the inlet, filtered by the filter 142, and finally a sample is obtained at the outlet for analysis and detection by the analysis device 150. According to the water quality detection analysis system 100 disclosed by the embodiment of the application, the precipitation device 120 is used for carrying out primary precipitation treatment on the water sample, so that the content of pollutants and the like in the sewage is effectively reduced, the filter device 140 is prevented from being blocked by the pollutants in the sewage to a certain extent, meanwhile, the water sample subjected to primary treatment by the precipitation device 120 is subjected to secondary treatment by the filter part 142 of the filter device 140, the impurity content in the sewage is further reduced, the interference influence of the pollutants in the sewage on analysis and test is effectively reduced, and the accuracy of water quality detection is improved.

The second liquid level sensor is arranged in the sedimentation shell 121 and is used for triggering the first power pump 110 to stop working when the water sample in the sedimentation shell 121 reaches a set height. Thus, in the process that the first power pump 110 pumps the water sample into the precipitation shell 121, the liquid level of the water sample in the precipitation shell 121 can continuously rise, and when the liquid level of the water sample rises to a set height, the second liquid level sensor can send a trigger signal to the background control end so as to control the first power pump 110 to stop pumping the water sample into the precipitation shell 121.
