Description

Sludge settlement ratio tester

Technical Field

The utility model relates to a sludge settlement ratio tester.

Background

Sludge settling ratio: taking 1000ml of mixed liquor at the tail end of the aeration tank, standing for 30min, and enabling the volume of the precipitated activated sludge to be the proportion of the volume of the whole mixed liquor. In the actual operation process, measurement is usually carried out by using a 100ml measuring cylinder for convenience of operation.

Because graduated flask is for experimental for measuring container in the existing market, its maximum scale is 100ml, and total volume will exceed 100ml, this just leads to measuring at every turn and need getting mixed liquid and get to 100ml, and different measurement personnel are because the operation proficiency is different, lead to the sample constant volume to have the error to cause the measuring result deviation. In the process of using the measuring cylinder for constant volume by a measuring staff, once the operation time is longer, the activated sludge begins to settle in the process of constant volume, so that the timing delay is caused, and the measuring result is influenced.

Measuring cylinders produced by different manufacturers on the market have different wall hanging conditions due to different cross sectional areas, so that the sedimentation speed is too high or too low, and the measuring results of the measuring cylinders of different manufacturers are inconsistent. As the measurement requires outdoor field measurement, the base of the measuring cylinder is light, and the measuring cylinder is easy to topple once wind exists outdoors. When outdoor measurement is carried out, once sunlight irradiates, the gas solubility is easy to reduce, bubbles are separated out, and therefore the measurement result is higher.
