Because the magnetic powder stimulate change, the elder brother, so that more than one polymer composition of protein content, there is a more marked increase performance improvement for sludge settlement with Figure 2 - 11, this is the same conclusion.

Because the magnetic powder stimulation changed outside the butcher gathers the composition, enable protein content to have a more distinct enhancement, the promotion sludge subsidence performance enhancement, this the conclusion which 2-11 obtains with Figure is same.

Due to the magnetic stimulus has changed the composition of extracellular polymeric substances, so that the protein content in a more obvious improvement, promoting improvement of sludge settleability, and 2-11 to get the same conclusion.
