Several sludge classification cases in water treatment industry
Sludge water treatment industry is a problem that often appears and need to be solved in the process. One of the most used product in sewage treatment is polyacrylamide flocculant, today I'm about to share the several ways of sludge classification with you.
Sludge classified by source of several ways:
The first: waterworks tank or thickener and chemical sludge discharge.
The second: the second pond, the discharge sewage plant of residual activated sludge.
The third: industrial wastewater generated by the expulsion of physicochemical and biochemical sludge thickener, such as paper, dyeing, washer wrinkle fabric factory, petroleum chemical, organic chemical plant, meat and brewery, etc.
Fourth: industrial wastewater generated by the concentrated tank from the physical method and chemical method of materialization of granular sludge, such as electroplating factory, circuit board factory, etc.
Fifth: industrial waste water treatment and chemical precipitation of granular sludge, such as alkali factory salt mud, steel desulfurization dusting features plant, aluminium plant red mud, sludge, sludge ceramics factory sludge, lime neutralization precipitation sludge, etc.
Sixth: industrial waste water treatment and chemical precipitation of coarse granular sludge: such as coal washery tail mud slag, glass, quartz, and so on.
According to the mechanism performance and processing speed of classification:
A, hydrophilic organic sludge, fine particle size, compressible performance is poor, dehydration performance is poor. As the second.
B, granular organic and inorganic hybrid sludge, compressible and dehydration performance in general. If above the first one.
C, the granular sludge mixture, fiber body dehydration performance is good, the rest can be compressed and dehydration performance in general. As the third.
D, granular inorganic sludge, compressible and dehydration performance in general. As the fourth.
E, granularity of hydrophobic inorganic sludge, compressible and dehydration performance is better. If above 5 type
F, coarse-grained hydrophobic inorganic sludge, compressible and dehydration performance is very good. If above 6 types.
