Online coliform group detection system

The invention discloses an online coliform group detection system. According to the system, a reagent storage unit is used for storing a cleaning solution, a culture solution and a sample solution respectively, unused disposable sterile hole discs are stored in a hole disc liquid-filling packaging unit, a liquid mixing and transferring unit sucks and transfers a liquid contained in the reagent storage unit to the unused disposable sterile hole discs, the hole disc liquid-filling packaging unit seals the hole discs after the liquid is filled, a hole disc transferring unit holds the sealed holediscs and transmits the hole discs to a culture detection unit, the culture detection unit performs constant-temperature culture on the hole discs, and can perform image recognition on the hole discscultured for a period of time, a control processing module gives a detection result based on the color change of each hole after image recognition and the number of holes with color change, and according to data in a maximum p
