METHOD FOR ACCELERATING SOLID-LIQUID SEPARATION OF SLUDGE |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To provide a method for accelerating the solid-liquid separation of sludge capable of obtaining high concentrated sludge for a short time as compared with a conventional gravitational concentration method while reducing the cost required in equipment or chemicals. <P>SOLUTION: In the method for accelerating the solid-liquid separation of sludge for treating an organic substance in sewage using microorganisms and drawing out generated sludge to treat the same, the drawn-out sludge is heated to a degree degenerating the polymeric substance in sludge to reduce the viscosity thereof to accelerate the sedimentation properties of sludge. <P>COPYRIGHT: (C)2003,JPO</p> |
