The thickener clarification layer height detection device comprises a control box, a control module, a cable, a cable reel, a counter wheel, a flange and a detection head are arranged in the control box, the detection head is electrically connected with the cable extending out of the lower end of the control box, and the detection head ascends and descends along with winding and unwinding of the cable. The detection head transmits detected signals to the control module in real time, and the control module judges the boundary position of the clarification layer and the suspension layer according to the received signals and calculates the height of the clarification layer. According to the characteristic that the clarification layer and the suspension layer are different in pressure and turbidity, the demarcation point of the clarification layer and the suspension layer is found through the pressure sensor and the turbidimeter, meanwhile, the height of the position where the sensor is located is measured by usi
