A water sample firstly enters a sand setting device through a water inlet pipe, and sand setting filtration is carried out to remove silt and algae in the water sample. After the water got into the sand setting device from the inlet tube, because the volume of sand setting device increases suddenly, the velocity of water reduces suddenly, and great silt particle of quality and alga can sink rapidly at the action of gravity, and the less water of quality then can circle round to rise to sand setting device top entering water inlet tank in, and the water yield can get into leading filter equipment through the pipeline after reaching the take the altitude in the water inlet tank. The water sample filters particle impurities in the water sample through the pre-filter device, then enters the filter blockage monitoring device, can be directly discharged through the first water outlet pipe if the requirement on the water quality of the water sample is not high, and can enter the centrifugal filter device for centrifugal filtration if the requirement on the water quality of the water sample is high, so that insoluble micro particle impurities in the water sample are removed, and then the water sample is discharged through the second water outlet pipe.
Adopt above-mentioned device, through multi-stage filtration, not only can get rid of silt sand, alga and large granule impurity in the water sample, can get rid of miniature granule impurity through centrifugal filter device moreover, not only reduce the consume to the device, guaranteed the quality of treating the monitoring water sample simultaneously, and then guaranteed to satisfy the quality factor and can monitor in the water sample environment that does not have impurity, guarantee monitoring data's accuracy. In addition, the device provided by the embodiment of the invention also comprises a filter blockage monitoring device, so that the blockage condition of the filter screen can be monitored, the blockage of the filter screen can be found in time, the normal work of the water quality monitoring and filtering device is ensured, and the accuracy of water quality monitoring factor data is further ensured.
In addition, the filter equipment that this embodiment provided has sand outlet and slagging-off mouth, and effectual cleaning device in time guarantees filter equipment's effective operation. Moreover, through setting up first outlet pipe and second outlet pipe, can satisfy the water sample filtration demand of different masses. When the requirement on the quality of a water sample is low in the monitoring of the water quality factor and a centrifugal filter device is not needed to remove insoluble micro particles, water can be discharged through the first water outlet pipe; when the requirement on the quality of a water sample is high in the monitoring of the water quality factor and insoluble micro particles need to be removed by using the centrifugal filter device, the water sample needs to enter the centrifugal filter device for centrifugal filtration after passing through the filter blockage monitoring device, and then is drained by the second water outlet pipe.
