Equipment for studying pipe network water quality stability under condition of simulating water source switch in situ

The invention provides equipment for studying pipe network water quality stability under the condition of simulating water source switch in situ, wherein the equipment comprises an in-situ test tube section for testing and a movable device. The in-situ test tube section for testing is obtained by separating a selected tube section of a water supply system and performing pre-connection treatment. The movable device comprises a water quality parameter detection device, a water quality regulation device and a running device. The water quality parameter detection device comprises a sampling device and a detection device; the water quality regulation device comprises at least one dosing system; the running device is used for connecting all devices for unified designing and programming to test the required water flow status and provide the power required by water flow. The equipment can realize in-situ simulation, can be connected with other equipment in situ on a place where the tube section is located, can simulate changes of water quality and flow state of a water source in an actual water supply pipe network, so as to obtain simulation data which is more accurate and reliable and closer to the actual status, and is beneficial to perform the reasonable prediction on the change of the pipe network water quality under the condition of water source switch.
