When SVI is low, the sedimentation performance is good, but the adsorption performance is poor. When SVI is high, the sedimentation performance is not good, even if it has good adsorption performance, it can not control sludge water separation well, it is generally believed that:
SVI〈100 sludge has good sedimentation performance
100〈SVI〈200 sludge settlement performance is generally SVI〉200 sludge settlement performance is not good
Under normal circumstances, the SVI value of urban sewage is between 50~150. |
