Measurement method for predicting sludge sedimentation ratio of 30-minute sludge sedimentation

The invention relates to a measuring method for predicting sludge settling ratio SV30 after sludge settling for 30 minutes. The experimental device comprises a light source (1), a conical container (2), an industrial camera (3), an upper computer (4), a temperature sensor (5) and a PH sensor (6). The method comprises a sludge feeding stage, a sludge settling stage and a data modeling stage. A model is established through data such as the PH value, the temperature and the concentration of sludge microorganisms in an experiment, so that the sludge sedimentation ratio SV30 can be predicted in a shorter time. The method has the advantages of simplicity in operation and high detection efficiency. 本发明涉及的是一种预测污泥沉降30分钟的污泥沉降比SV30的测量方法。实验装置包括光源(1)、锥形容器(2)、工业相机(3)、上位机(4)、温度传感器(5)和PH传感器(6)组成。本发明包括污泥物进料阶段、污泥沉降阶段和数据建模阶段。实验通过PH值，温度和污泥微生物的浓度等数据建立模型实现更短时间内预测出污泥沉降比SV30。本发明具有操作简单和检测效率高的优点。
