Description
Technical field
The utility model relates to a kind of devices of Treatment of Sludge in industrial building and hydraulic engineering.More particularly to a kind of use
It sets in the geotextile tube of the built-in drain bar of sludge dewatering is packed.
Background technique
Sludge includes by the different semisolid of the moisture content generated in sewage disposal process or solid matter (industrial sludge)；
Or the mud (dredging silt) generated by city river, lake dredging dredging engineering and city sewer；Or by wet dressing
The waste (tailings mud) based on fine grained generated.Since Chinese Urbanization is quickly grown, sludge yield increases year by year.
According to related literatures, the cities and towns of China in 2014 industrial sludge yield is about 2801.47 ten thousand tons, increases by 11.57% on a year-on-year basis.Water
Always collection amount surpasses 1 billion cubic meter to the sharp annual dredging silt of engineering.The tailings mud annual output in mine surpasses 300,000,000 tons, and with annual 2% speed
Degree increases.
Treatment of Sludge be exactly above-mentioned sludge is concentrated, is recuperated under medical treatment, is dehydrated, is stablized, the process of desiccation or burning, it is real
The minimizing of existing sludge, stabilisation and innoxious.Due to sludge components complexity, containing sex pheromone, parasitic ovum, toxic have
Harmful heavy metal and a large amount of hard-degraded substance is easy to cause secondary dirt to water body, soil and atmosphere if dealing with improperly
Dye.However, the phenomenon that wastewater treatment in China generally existing " light mud of heavy water ", so that wastewater treatment in China is fast-developing, at sludge
Reason is but stagnated, and Treatment of Sludge notch is huge.By the sewage sludge harmlessness disposing that the end of the year 2014, national sewage treatment plant generate
Rate is only 56%, and main disposal options are sanitary landfills, burning, system fertilizer, manufacture building materials.In remaining sludge, about one third
It is disposed using " expedient ", excess sludge whereabouts unknown.
Hesperian extensive modernization Treatment of Sludge is about since the late sixties.The European Community passed through in 1986
" European Parliament's environmental protection, particularly agricultural sludge land protection criterion ", passed through " at European Community's municipal wastewater in 1992
Logos enables ", and European Union's Sludge landfill guideline has been promulgated in 1999.U.S.EPA also proposes life at the beginning of 1989
Sewage plant sludge handles and utilizes rule, and volume 503 sewage sludges processing rule was disclosed in 1993.Although Japan is without list
Sludge treatment regulation is solely worked out, but is present in the relevant regulations of soil, underground water, landfill, fertilizer etc. to the limitation that sludge uses
In.Due to being influenced by a series of environmental protection policies, Treatment of Sludge is just gradually being typically canonicalized in the whole world.
The Chinese government has issued " urban sewage treatment plant sludge disposition-blended landfill shale " standard (CJ/ in 2007
T249-2007), wherein 60% should be lower than for the moisture percentage in sewage sludge of blended landfill by defining, undrained shear strength need to be greater than
25kPa.In 2010, " People's Republic of China's state environment protecting standard (HJ564-2010): house refuse was filled out for publication
Bury percolate processing engineering legislation (tentative) ".
China's currently used heap mud field sunning processing, easily pollutes the secondary pollutions things such as object leakage, migration, fugitive dust
Therefore and dewatering time it is long, effect is unobvious, there are still sludge storage and reprocessing the problems such as.According to mechanical dehydration method
(such as plate compression) handles sludge, and since mud granule is tiny, waterpower osmosis performance is very poor, and there are still efficiency to compare for current art
It is low, the problems such as processing cost is relatively high.European and American developed countries actively research and develop high-effective sludge dehydration technology, including electric osmose at present
Dehydration technique, freeze thawing treatment technology, ultrasonication technology, membrane separation technique etc., but all there is equipment one-time investment height, build
If plant building, treating capacity are small, at high cost, processing capacity is not able to satisfy of short duration construction period (such as dredging silt of scene improvement
Processing) etc. a series of deficiencies.
In summary, a large amount of sludge for how dealing carefully with fast urbanization in current china generation make it stabilize, is harmless
Change, minimizing, recycling, it has also become urgent problem to be solved in environmental pollution improvement.Using New Type of Sludge Dewatering processing method,
Carry out and accelerates sludge dewatering, reduce soil occupied area, reduce sludge dewatering cost and carry out large-scale engineering applications direction
Research has important engineering significance and application value.
Geotextile tube bag is by geotextile by sewing, the tubulose formed and charging mud, mortar or water
Structure.Under the collective effect of pipe bag restraining force and internal water pressure, free water body is oozed out by the gap of geotextile, and is consolidated
Body particle has then been retained in inside geotextile tube bag.Geotextile tube bag technique is in China, Australia, South Korea, Japan and the U.S.
Equal countries are widely used in the construction works such as seashore protection against erosion dam construction, flood control and dredging.
Sludge dewatering is carried out using geotextile tube bag, at low cost with its, treating capacity is big, it is easy to the advantages such as execute-in-place, by
The attention of environmental protection circle personage has been widely used for the de- of the sludge such as trade effluent, lake river silt, industrial wastewater, tailings mud
Water.Since dewatered mud moisture content can be lowered to 50-60% or so, land transport, recycling can be easily carried out
Using or processing.It is compared with the traditional method compared with using the progress sludge dewatering of geotextile tube bag, process performance is more stable, technique letter
List, excellent result, total investment and processing cost bottom, thus have more the market competitiveness.
But, traditional geotextile tube bag sludge dewatering usually requires 1-2 months spin cycles.At extensive sludge
Reason, this spin cycle are too very long.At present common acceleration mud dewatering method can be with rough segmentation include chemical method and physical method.
Flocculant is the method that the most commonly used chemical method accelerates sludge dewatering.Flocculant be mainly have the group of positive (negative) electrical property with
It is close to each other with negative (just) electrical some particles for being difficult to separate or particle in water, its potential is reduced, is at not
Stable state, and using its aggregation property these particles are concentrated, and divided by subsequent physics or chemical method
From.Stacking is the method that the most commonly used physical method accelerates sludge dehydration process, is accelerated by the weight of top geotextile tube bag
The process of sludge dewatering in the geotextile tube bag of lower part.This method construction is simple can make the sludge moisture content in lower tube bag subtract
Less to 60% or less.But lower layer's geotextile tube bag can generate tension spikes when stacking, and increase the risk of lower layer's pipe bag breakage.
Experimental study shows that, in upper layer geotextile tube bag heap poststack, lower layer's pipe bag warp tension ratio is uprushed before applying up to 140.8%.
Therefore the strength of materials of lower layer's pipe bag is required to increase, that is, increases engineering material cost.In addition, lower layer's pipe bag quilt in stacking
It pushes down in flat, it is not possible to charge again, not give full play to the performance of material.
Summary of the invention
