Abstract：
Analyses the operating principle of semi-submerged rotary orifice plate sewage intake machine, and develops the dynamic mathematical model and steady-state mathematical model with position. Based on the steady-state mathematical model, provides the calculation method of the orifice plate filter capacity, the orifice plate filter load and the average blockage coefficient of orifice plate, and illustrates a calculation example. Based on the calculation result, analyses the effect of contaminant concentration on the orifice plate filter capacity, the filter load and the average blockage coefficient of orifice plate. Presents the performance test method and performs the field test of intake machine applied in an actual project.
