Abstract
The invention belongs to the field of sludge treatment technology for spinning industry, and relates to a sludge treatment method, in particular to a spinning sludge treatment method. The spinning sludge treatment method comprises the three steps in sequence: A. drying; B. preparing mud cake; and C. producing oil and the like. According to the spinning sludge treatment method provided by the invention, oil in sludge can be effectively processed, especially the spinning sludge with rich oil has good application value in processing; the defect in the prior art that the sludge is generated in sewage treatment can be overcome, only two treatment methods are available, namely embedding and burning which both have secondary contamination to the environment, especially the defect more difficult to treat, namely the oil substance in the sludge; and the method can carry out advanced treatment on the spinning sludge, improves the water recovery rate, reduces the total discharge amount of sludge and pollutant, and has good application prospect in the field of sludge treatment technology for the spinning industry.
Description
Technical field
The invention belongs to textile industry technical field of sludge treatment, relate to a kind of method for sludge treatment, relate in particular to a kind of weaving method for sludge treatment.
Background technology
The features such as textile industry waste water has that the water yield is large, complicated component, environmental pollution are serious.The domestic improvement to such waste water at present, mostly still take qualified discharge as object.Increasing of the sustainable growth of the scarcity of water resources, economy, population, will cause the relatively in short supply of water resources.Concerning this class water rich and influential family of textile industry, water resources is recycled, be not only the needs that promote economy, environment, society's coordinated development, be also the needs of textile industry Sustainable development.
Pollutent in textile waste is mainly dirt, salt and the lipid on the textile fibress such as cotton wool, and the various slurries that add in the course of processing, dyestuff, tensio-active agent, dyeing and finishing processing aid, acid, alkali etc.Because textile process process is various, cause on the one hand sewage complicated component, difficult treatment, also improved on the other hand the requirement to water water quality, the result of comprehensive two aspects is to make the difficulty of textile sewage reuse large, and cost is high, is difficult in industry generally apply.
Textile industry generally adopts the sewage producing in biochemical treatment process processing production process at present, need to be aided with necessary pre-treatment and physical chemistry treatment process simultaneously, textile sewage is processed after meeting the standard of < < GB/T4287-92 > > and discharged.But the mud for producing after disposing of sewage, only has two kinds of methods to process substantially in prior art, the one, landfill, the 2nd, to burn, these two kinds of methods, all to naturally producing in secondary pollution, particularly mud and contain oil substances, are difficult to process more.
Summary of the invention
The present invention is directed in prior art for the mud producing after disposing of sewage, substantially only have two kinds of methods to process, the one, landfill, the 2nd, to burn, these two kinds of methods are all to naturally producing in secondary pollution, particularly mud and contain oil substances, more reluctant defect, object is to provide a kind of weaving method for sludge treatment, and effectively the grease in lignin-sludge, special in having fine using value in the processing containing the more weaving mud of grease.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals:
A weaving method for sludge treatment, is comprised of following step successively,
A. dry: with steam, weaving mud is carried out to heating, drying, reduce the water content of weaving mud, form weaving sludge slurry;
B. mud cake processed: weaving sludge slurry is rolled into mud cake with filter cloth, and filter cloth used is the macromolecular filtering cloth that has ventilation property;
C. fuel-displaced: with pressing machine, mud cake to be pressurizeed, make it fuel-displaced, then discharge.
Weaving mud is carried out to heating, drying, after reduction water content, go out oil treatment again, fuel-displaced effect is more remarkable.Macromolecular filtering cloth has different specific aims and selectivity to the various pollutents and the water that contain in weaving sludge slurry, more easily make the pollutents such as grease carry out separated with water, make oil yield higher, mud oleaginousness is after treatment lower, improve recycle-water rate, reduce the total emission volumn of sewage and pollutent.
As preferably, the vapor temperature in steps A is 200～1000 ℃.Can be as required and the oleaginousness of mud, and according to the consideration of economic benefit, vapor temperature is regulated.
As preferably, in steps A, in heating, drying process, weaving mud is stirred simultaneously.Whipping process is except making drying course accelerate, and can be so that the weaving sludge slurry arriving is more even, is conducive to follow-up fully fuel-displaced.
As preferably, the water content of the weaving mud in steps A is reduced to 30～50%.
As preferably, the macromolecular filtering cloth in step B is terylene filter cloth, polypropylene fibre filter cloth, polyamide fibre filter cloth or polyvinyl filter cloth.Can select according to the contained fat type of weaving mud and the difference of oleaginousness.
As preferably, the moulding pressure of the pressing machine in step C is 60～100t.
The invention provides a kind of weaving method for sludge treatment, the effective grease in lignin-sludge, especially for having fine using value in the processing containing the more weaving mud of grease, overcome in prior art for the mud producing after disposing of sewage, substantially only have two kinds of methods to process, the one, landfill, the 2nd, burn, these two kinds of methods are all to naturally producing secondary pollution, particularly in mud, contain oil substances, more reluctant defect, weaving mud is carried out to advanced treatment, improve recycle-water rate, reduce the total emission volumn of mud and pollutent, in textile industry technical field of sludge treatment, have a good application prospect.
Embodiment
Below in conjunction with embodiment, the present invention is described in further detail.
Embodiment
A weaving method for sludge treatment, is comprised of following step successively:
A. dry: with steam, weaving mud is carried out to heating, drying, reduce the water content of weaving mud, form weaving sludge slurry;
B. mud cake processed: weaving sludge slurry is rolled into mud cake with filter cloth, and filter cloth used is the macromolecular filtering cloth that has ventilation property;
C. fuel-displaced: with pressing machine, mud cake to be pressurizeed, make it fuel-displaced, then discharge.
Wherein, the vapor temperature in steps A is 200～1000 ℃.In the present embodiment, select 800 ℃.
In steps A, in heating, drying process, weaving mud is stirred simultaneously.
The water content of the weaving mud in steps A is reduced to 30～50%.In the present embodiment, select the water content of weaving mud to be reduced to 40%.
Macromolecular filtering cloth in step B is terylene filter cloth, polypropylene fibre filter cloth, polyamide fibre filter cloth or polyvinyl filter cloth.In the present embodiment, selecting macromolecular filtering cloth is polypropylene fibre filter cloth.
The moulding pressure of the pressing machine in step C is 60～100t.In the present embodiment, the moulding pressure of selective pressure machine is 80t.
The landfill of prior art or the method for burning, the pollutent of lipid is still discharged in physical environment in a large number, environment is caused to secondary pollution, and with respect to prior art, the present invention just can carry out advanced treatment to weaving mud, improve recycle-water rate, reduce the total emission volumn of mud and pollutent, in textile industry technical field of sludge treatment, have a good application prospect.
