The utility model provides an automatic pretreatment system for analyzing and sampling water quality. The automatic pretreatment system comprises an analysis instrument, a controller, a grit chamber and a water sampling pump, wherein the analysis instrument is connected to the grit chamber, so as to collect a water sample from the grit chamber; the water sampling pump is connected to the grit chamber through a sample inlet pipe, so as to convey the water pumped from a sampling point to the grit chamber via the sample inlet pipe; the grit chamber is also connected with a drainage pipe; the controller is respectively connected with the analysis instrument, the water sampling pump and valves which are respectively arranged on the sample inlet pipe and the drainage pipe, so as to receive a sampling signal emitted by the analysis instrument, control the water sampling point to pump water from the sampling point, and control the valves on the sample inlet pipe and the drainage pipe to open and close. Through the automatic pretreatment system, accurate and reliable analysis water samples can be provided for the analysis instrument; meanwhile, the system is reliable, stable and efficient to run by adopting an information technology; and the operation maintenance quantity is small.
