The utility model relates to the technical field of sewage treatment, in particular to a multi-path water sample orthophosphate on-line detection system for a sewage plant, which realizes sampling detection of a plurality of process units of the sewage plant by one orthophosphate on-line analyzer through switching of sampling pipes, greatly reduces the cost of purchasing a plurality of orthophosphate on-line analyzers, and improves the detection efficiency of the orthophosphate on-line analyzers. The two-stage pretreater arranged on the sampling pipeline can effectively remove particulate matters in sewage, the influence of impurities on a detection system of the orthophosphate online analyzer is avoided, the service life of the orthophosphate online analyzer is remarkably prolonged, the measurement precision of the orthophosphate online analyzer is remarkably improved, in addition, water samples are always in a flowing state due to the arrangement of the water sample overflow pipeline, and the sampling effic
