Embodiment
Below with reference to accompanying drawing 1, the technical scheme of the present invention is described in detail.
Embodiment 1
In this embodiment, the mud dewatering method of flocculation amendment coupling ultrasonic oxidation utilizes cationic-type polyacrylamide and flaxen fiber powder to be conditioning medicament, and concrete Opsonizing method comprises the steps:
Step 1, flaxen fiber is crushed in crusher the flaxen fiber powder that granularity is below 3mm;
Flaxen fiber granularity is excessive, easily precipitates, and evenly can not disperse in mud, thus causes flaxen fiber evenly can not disperse in sludge filter cake, and sludge filter cake dehydrating effect is not good. Meanwhile, flaxen fiber granularity crosses conference increases its consumption, and researchist surprisingly finds, time flaxen fiber powder is the mixture of 0-3mm, effect is more effective than Monosized powder, therefore, present invention employs the flaxen fiber of different globule sizes.
Step 2, being soaked in the dilution heat of sulfuric acid of concentration 1.5-2.0g/L by flaxen fiber powder, flaxen fiber powder and dilution heat of sulfuric acid mass ratio are 1:10-1:15, temperature 40-60 DEG C, time 1-2h, rinse post-drying with water;
Step 3, flaxen fiber powder is soaked in the sodium hydroxide solution of concentration 15-80g/L, adding auxiliary agent S-WAT and make its concentration be 1-5g/L, flaxen fiber powder and sodium hydroxide solution mass ratio are 1:10-1:15, temperature 100-120 DEG C, time 1-2h, rinse post-drying with water;
Single flaxen fiber condenses together in pencil owing to there is the impurity such as colloid, xylogen on surface. It is ultimate fibre that removal colloid and xylogen can make fibrous bundle loose, can reduce the consumption of flaxen fiber.
Step 4, flaxen fiber powder at room temperature put into diesel oil soak 0.5-2h after take out, the mass ratio of flaxen fiber powder and diesel oil is 1:10-1:15;
Flaxen fiber powder diesel oil soaks, and can significantly improve the combustionproperty of formed filter cake.
Step 5, being added water by cationic-type polyacrylamide is mixed with the solution that mass percent is 0.05%-0.5%;
Cationic-type polyacrylamide can be caught by electrical counteract, adsorption bridging, net and volume the effect such as is swept and made mud granule form agglomerate, shortens filtration time, reduces the moisture of sludge filter cake.
In addition, cationic-type polyacrylamide belongs to organic polymer, does not generate residue and toxic gas completely, the burning of sludge filter cake is not had negative effect after burning.
Step 6, mud using the ultrasonication 0.2-2h that frequency is 28kHz-120kHz, energy input is 1-9 �� 106KJ/t mud does matrix amount;
1-9��106The dry base quality representation ultrasonic wave of kJ/t mud, to mud institute work, converts according to the dry matrix amount of kJ/t mud.
Step 7, in mud, lead to the O into the dry matrix amount of 10-50kg/t mud3, process 0.2-0.5h;
The dry base quality representation of 10-50kg/t (kg/ton) mud is led in mud and is participated in the O of mud oxidizing reaction3Total amount, convert according to the dry matrix amount of kg/t mud.
Ultrasonic wave, oxidation pre-treatment can take off except mud extracellular polymeric, it is to increase sludge dewatering effect.

As shown in Figure 1, flaxen fiber is made up of 6-30 unicellular fiber, and these unicellular fibers are connected by middle lamella, and unicellular fiber comprises nascent layer, secondary layer, inside have duct, it is possible to as draining passage.
Flaxen fiber powder has certain physical strength, can form the structure of hypertonicity with mud granule, reduce the compressibility of sludge filter cake, it is to increase the perviousness of sludge filter cake. The more important thing is, owing to flaxen fiber powder has hollow structure, these ducts as the drainage pipeline in sludge filter cake, can increase the water draining pass in sludge filter cake, improve the dehydrating effect of sludge filter cake.
As shown in Figure 1, the cross section of flaxen fiber distributes relatively porous, illustrates that flaxen fiber has hollow structure, and these ducts as the drainage pipeline in sludge filter cake, can increase the water draining pass in sludge filter cake, improve the dehydrating effect of sludge filter cake. This is that currently available technology has found the outstanding advantage that material does not possess, and this characteristic brings the unexpected technique effect of the application.
Step 9, continuing to add cationic-type polyacrylamide, stir evenly, dosage is the 0.05%-0.4% of the dry matrix amount of mud;
First add flaxen fiber powder, after add in the agglomerate that cationic-type polyacrylamide can make flaxen fiber powder be formed at mud and be uniformly distributed, thus be uniformly distributed in sludge filter cake, improve sludge filter cake dehydrating effect better.
Studying discovery through for a long time, when first adding cationic-type polyacrylamide, cannot ensure flaxen fiber powder being uniformly distributed in sludge filter cake, in filter-press dehydration process, being uniformly distributed dehydrating effect impact of flaxen fiber powder is very big.
Step 10, by mixed mud send into plate-and-frame filter press dehydration, by dehydration after mud dry or warehouse ventilate stack after obtain biodiversity lower than 60% sludge filter cake.
Due in these examples of implementation, sludge filter cake meet burning boiler enter to expect requirement, and comprise the flaxen fiber powder of certain content because of sludge filter cake, sludge filter cake thermal value increases, do not produce during burning burning boiler is run disadvantageous slag, do not discharge toxic and harmful, environment is not polluted.
