| 摘要 |
The process is compression of the sludge, measurement of the pH thereof and reducing this value by sludge treatment with a coagulant, heating the sludge, treatment thereof with a flocculant, mechanical dewatering and subsequent neutralisation. The pH is reduced in this to the extent that it corresponds to the isoelectric sludge state and heating is carried out up to a temperature of 65 to 75 DEG C. |
