以往常采用明渠流量计测回流污泥量，不仅误差大，而且流量系数转换、标定都十分困难。
Traditionally the flowrate of returning activated sludge was measured by open channel flowrate meter with higher error, difficult transform of flowrate coefficients and inconvenient calibration.
并就污泥回流对除磷的影响进行了模拟试验，结果说明污泥回流可以节约药剂投加量。
Moreover, a simulated experiment on the influence of the reflux sludge on the dephosphorization was carried out. The result indicates that the sludge reflux can save the medicaments.
