Abstract
The invention relates to a preparation for reducing the viscosity of city life sludge and a method thereof, which is characterized in that a preparation that is 1-2wt% of the rest sludge and is used for reducing the viscosity of city life sludge is added into the sludge and mixed uniformly after the overtreatment of city sewage treatment plants, wherein, the preparation for reducing the viscosity of city life sludge is prepared from one or more of the four pharmaceutical products of sodium carbonate, sodium chloride, sodium hexametaphosphate and sodium metasilicate and one or more of the five pharmaceutical products of naphthalene sulfonic acid formaldehyde condensation product, sodium lignosulphonate, tartrate, potassium ferrate and ferric chloride. Compared with the prior art, the invention has the advantages that the cost is low, after the overtreatment of city sewage treatment plants without secondary pollution, the viscosity of the rest sludge is reduced, thus leading the sludge to have the viscosity of fuel, and the transportation is convenient.
Description
Technical field:
The present invention relates to a kind of treatment process of municipal sludge.
Background technology:
Cross the excess sludge after handling through the municipal sewage plant, main organism by high heating value constitutes, and these mud have the value that acts as a fuel, and still, are subjected to the restriction of the physicals of its too high viscosity, have influenced its flowability, makes it can't trouble-free burning.Though, below several prior aries can both reduce the viscosity of mud, these technology are as described below:
1. alkaline purification method
In mud, add highly basic energy protein hydrolysate and nucleic acid, the enzyme system and the structure of cell are suffered damage, also can decompose the carbohydrate in the thalline, make cell inactivation, destroy cell walls, intracellular organic matter is discharged in the surrounding environment, thereby is converted into dissolved matter by insoluble particulate matter.Shortcoming: can change the chemical constitution of mud, increase the ionic concn in the mud, the follow-up recycling treatment of mud is made troubles, for example acidic substance can corrode transportation equipment.
2. acidic treatment
Contain certain amphiprotic substance in the extracellular polymeric of sludge microbe, these amphiprotic substances can dissolve under acidic conditions, be converted into dissolved matter, thereby the flco structure of mud is had certain destruction.Shortcoming: the mud after the acidifying is too strong to the corrodibility of equipment, and may make sulfide change into sulfurous gas.
3. heat treating process
The thermal treatment meeting causes the structural damage of mud flco, destroys the cell walls of mud cell, causes the fragmentation of mud cell, and intracellular organic matter is discharged in the surrounding environment, and the extracellular polymeric of sludge microbe also can dissolve in heat treatment process.Shortcoming: need the input heat, certain energy consumption is arranged, and small organic molecule can evaporate in the mud, cause the mud stink to strengthen.
4. ozone method
Ozone has stronger oxygenizement to microorganism cells, and causes cytolysis.Shortcoming: the processing cost height, the effluent quality variation, nitrogen and phosphorus content is too high in the water outlet.
5. supersonic method
Ultrasonic wave utilizes cavitation effect can form a kind of extreme environment of High Temperature High Pressure in moment, and the effect of successive high-frequency ultrasonic can the dissolution of bacteria spore, destroys the zoogloea structure, improves the solvability of mud.Shortcoming: ultrasonic power haves much room for improvement to the solute effect of mud, and is present satisfied not enough.
Though above-mentioned technology has reduced the viscosity of mud to a certain extent, owing to limited by the purpose of these technical finesses, all can not satisfy the requirement that sludge treatment is become fuel.
Summary of the invention:
Goal of the invention of the present invention is to provide a kind of viscosity that the excess sludge after handling is crossed by the municipal sewage plant to reduce, make its satisfy the reduction municipal sewage sludge viscosity that becomes the viscosity that fuel has preparation and method.
The preparation of reduction municipal sewage sludge viscosity of the present invention is achieved in that by yellow soda ash NaCO

3One or more chemical contents in two kinds of medicaments are 25-30wt%, and the naphthalene sulfonic acidformaldehyde condensation product chemical content is 22-25wt%, and the sodium lignosulfonate chemical content is 10-15wt%, and the tartrate chemical content is 12-16wt%.During use, preparation is blended into the municipal sewage plant crosses in the processing excess sludge afterwards potassium ferrate K in the preparation
2FeO
4, iron(ic) chloride FeCl
3As residual flocculation agent in the oxygenant degraded mud, eliminate the sewage sludge viscosity influence that causes because of flocculation agent; Yellow soda ash NaCO
3, sodium chloride nacl, Sodium hexametaphosphate 99 (NaPO
3)
6, Starso Na
2SiO
3Be electrolytic salt, eliminate the mud micelle that aggregates into because of charge attraction power, make earth rubber group be converted into non-flocculation state by the flocculation state; Tea sulfonic formaldehyde condensation compound, sodium lignosulfonate, tartrate play dispergation, dissemination as dispersion agent to the mud micelle.Under the effect of above-mentioned preparation, the viscosity that the excess sludge after handling is crossed by the municipal sewage plant descends significantly, thereby has improved the flowing property of mud significantly, makes mud both be convenient to transportation, and reaching again becomes the needed physicals of fluid fuel.
The method of reduction municipal sewage sludge viscosity of the present invention is achieved in that the 1-2wt% that above-mentioned preparation is crossed the excess sludge after handling by the municipal sewage plant adds to mix in the mud and gets final product.
Compared with the prior art the present invention has the viscosity that low cost, non-secondary pollution ground cross the excess sludge after handling with the municipal sewage plant and reduces, and it is satisfied becomes advantage viscosity, that be convenient to transport that fuel has.
Embodiment:
Now in conjunction with the embodiments the present invention is described in further detail:
