Description
Technical field
The present invention relates to technical field of sludge treatment, specifically disclose a kind of sludge solidifying agent and preparation method thereof and use
Method.
Background technology
Operation with large amount of sewage treatment plant runs, and sludge yield will significantly increase.According to the literature, 2011
China's total amount of sewage discharge reaches 482.4 hundred million tons, produces 8,470,000 tons of excess sludge (dry mass), and the remaining dirt discharged every year
Mud amount is with average annual about 10% speed increase.In addition, the Organic substance in biological wastewater treatment process, in micropopulation and sewage
Contact, picked-up organism in water decompose composition carry out growth and breeding, in this process hypertrophy glue plumage formed bacterium can with from status
Remaining suspension solid in the extracellular polymeric secreted, aqueous phase, filamentous bacteria, funguses, protozoacide and divalent calcium, magnesium ion, altogether
With assembling the mud glue plumage connecting to about hundreds of microns of size, its short texture, moisture content is high, and has huge surface area and height
Degree hydrophilic, with combining water in a large number, leads to Treatment of Sludge difficulty to increase.Therefore, the process of mud is examined with disposing day by day to become
Core sewage treatment plant runs the important indicator of performance.
Moisture in mud is divided into four kinds by its state：1) Interstitial Water, Interstitial Water is the free water that mud granule surrounds
Point, typically constitute from the 70% about of mud total moisture content；2) capillary water, capillary water be between mud granule or in particulate fractures due to
The moisture that capillarity and mud granule are combined together, accounts for the 20% about of total Water；3) adsorb water, absorption water is due to table
The moisture on mud granule surface for the effect absorption of face tension force, because mud granule is little, has extremely strong superficial attractive forces；4) tie
Heshui, is included in the intracellular moisture of sludge microbe in conjunction with water, and the internal structure only changing mud granule could will be tied
Heshui separates；Account for 10% about of total moisture content in mud in conjunction with water and absorption water altogether.
Sludge dewatering actually refers to remove the Interstitial Water in mud.Interstitial Water easily removes in theory, but due to
Mud is to be formed by cotton-shaped colloid set, and granule is very thin and very soft, because soft granule has certain compressibility, works as external force
During increase, granule can be very little " film " in one layer of space of filter media surface formation, so that water is difficult to pass through, dehydration is also
Seem abnormal difficult.
The modifier treatment of mud is key link and the core technology of sludge dewatering.Modifier treatment is exactly the glue destroying mud
State structure, reduces the affinity between muddy water, improves the dewatering of mud.
