The method for knitting printing and dyeing sludge.
Background technique
A large amount of sludge can be generated in sewage disposal process, volume is big, and moisture content is high, typically up to 98-99%, therefore
The dehydration of sludge is always global problem.It is mechanical when being carried out using plate and frame filter press, belt type dewaterer or centrifugal dehydrator etc.
Rate of water loss is slow when the solid-liquid separating methods such as dehydration or vacuum dehydration are dehydrated, and dewatering time is long.
The minimizing of sludge volume is one of vital task of Treatment of Sludge, therefore usually requires first to carry out before sludge dewatering
Concentration to reduce sludge volume, but usually contains a large amount of organic matter in textile printing and dyeing sludge, such as starch, modified shallow lake
Powder, polyvinyl alcohol, sodium alginate, adhesive etc., hydrophily is strong, and viscosity is big, dense using conventional sludge in conjunction with water content height
Contracting technology such as precipitation concentration, floatation thickening are difficult to reach good concentrated effect.It is low that there are cycles of concentration, reduction difference etc.
Problem, sludge volume is still huge after concentration, and some sludge, which even is difficult to be concentrated, is unable to muddy water layering, and sludge dewatering is difficult.

Sub- copolymer Tg reverts to glassy state hereinafter, copolymer molecule chain is made to change physical state, and three-dimensional framework support is formed after hardening
Hole between mud granule reduces sludge specific resistance, and then sludge removes filtering means dehydration.
The utility model has the advantages that
A. in water phase acid out formed glass transition temperature temperature above room temperature responsiveness aqueous high molecular copolymer by pair
The variation that physical state occurs above and below glass transition temperature for the response of temperature realizes that sludge-heat preservation drilling-hardening is cohered in softening
Permeable pore canal role is supported, the sludge for being difficult to be concentrated is concentrated further, reduction is obvious, and sludge volume can be reduced to
30% hereinafter, cycles of concentration improves 4 times or more than conventional precipitation concentration method, than conventional floatation thickening method raising 2 times or more.
B. the effect of rolling up of temperature-responsive aqueous high molecular copolymer molecule chain, can drive mud granule height after being heated
Reunion and deformation retract, make sludge condensation and form hole between mud granule, constitute dehydration duct when filtering means dehydration.
C. the carboxyl in temperature-responsive copolymer being precipitated can be acted on the hydrophilic group of mud granule, reduce sludge
Active force between grain and water, while the hydrophobic groupings such as methyl, ethyl, ester group in copolymer further increase mud granule
Hydrophobicity, and by the surface property of gas-liquid-solid three-phase interface change sludge, the content for combining water in thickened sludge is reduced, is conducive to
Sludge condensation.
D. temperature-responsive aqueous high molecular copolymer is converted to hole between glassy state after-hardening support mud granule, can subtract
Sludge pore deformation, collapsing when few filtering means dehydration, sludge specific resistance can be reduced to original 10% hereinafter, dirty by sad filter after concentration
Mud is transformed into easy filter sludge, and filtering velocity is accelerated, and shortens filtration time.
E. the microbubble of inorganic solid particle reaction release forms gas, liquid, solid three on mud granule surface and is in contact boundary
Face is reduced solid-liquid contact, and is risen with temperature, and microbubble release is accelerated, and concentration water outlet is made easily to sink to forming water layer by gravity,
Improve concentrated effect.
