1. An automatic measurement system for Sludge settling Velocity, comprising:
a sampling and shooting module, wherein the sampling and shooting module is configured to collect mud-water mixture samples and to obtain test images of the mud-water mixture samples, wherein the sampling and shooting module comprises:
a test container configured to hold the mud-water mixture samples;
a lifting mechanism configured to inject the mud-water mixture samples into the test containers:
a CCD camera configured to obtain the test images of the mud-water mixture samples;
a flushing mechanism configured to clean the test containers; and
a PLC controller configured to control the operation of the lifting mechanism and the flushing mechanism;
a measurement and analysis module configured to:
acquire the test images and to acquire the sedimentation ratios of the mud-water mixture samples according to the test images;
analyze sludge activity according to the Sludge settling Velocity of the mud-water mixed liquid samples during the sedimentation process, and then to judge whether the sludge activity is abnormal according to the result of the sludge activity analysis; and
obtain the process data of the mud-water mixture samples from a data processing module when the sludge activity is abnormal, and then to obtain the data of process analysis according to the process data and the results of sludge activity analysis, wherein the data processing module is configured to collect and store the process data during the operation of the sewage treatment process system; and
a data service module configured to store and manage the data of the test images and the Sludge settling Velocity.
