Abstract

In order to master the rheological properties of temporary sludge, the sludge in Shanghai Laogang temporary storage area was sampled, and the rheological properties test was carried out. The effects of temperature, solid content and other parameters on the rheological properties of sludge were analyzed. Based on the above research and analysis results, the key parameters that affect the rheological properties of sewage sludge were analyzed, and combined with previous research conclusions, the methods such as summary and numerical fitting were used. The sludge function expression of the rheological characteristics of the temporary storage sludge is obtained, which provides theoretical guidance for the transport of sludge in the temporary storage area.
