Pollution source online monitoring alarm system

The utility model relates to the technical field of pollution source monitoring and alarming, and discloses a pollution source online monitoring and alarming system which comprises a waste pool body,a monitoring mechanism used for monitoring the water level of a pollution source is arranged above the waste pool body, two vertical plates are arranged in the monitoring mechanism, and a rotating column is arranged between the two vertical plates. By arranging the warping plate and the rotating plate, when the water level in the waste pool body starts to rise, buoyancy generated by the liquid level of the water level drives the floating plate to rise in a floating mode, so that the floating plate can rise in a floating mode more easily, and the waste pool body is prevented from falling off. At the moment, the left side of the floating plate rotates upwards with the rotating column as the center, and meanwhile the right side of the floating plate descends in the right direction, so that the alarm bell starts alarm
