Description
Technical field
The present invention relates to a kind of sludge treatment equipment, more particularly to a kind of sludge cell wall breakage device and its thin for sludge
The method of born of the same parents' broken wall, belongs to sewage resource technical field of comprehensive utilization.
Background technology
After National Development and Reform Committee in 2007 proposes the bill of energy-saving and emission-reduction, more and more subtract there has been proposed energy-conservation
The gold-idea of row.Plus the natural calamity and the big phenomenon of climate change that occur again and again in recent years, country proposed in 2008 again
The concept of " low-carbon (LC) ", advocates low-carbon (LC) and lives to this year also increasing people.With economic fast development, China
The handling rate of municipal sewage and industrial wastewater is also being improved year by year, while also a large amount of along with also being generated in treatment stain disease
Sludge, it is reported that, 2009, China urban wastewater treatment firm statistics had 1992, and annual sewage load is up to 28,000,000,000 m3,
Doubled compared to " 15 " initial stage, produce about 20,050,000 tons of the sludge of moisture content 80%.Is produced from each municipal sewage plant of China
Raw wet mud up to more than 3,000 ten thousand tons, will account for more than the 5% of China year total solid waste discharge amount.If sludge treatment is not
When, substantial amounts of limited arable land is not only taken, can also serious pollution be caused to ground surface environment and underground water.According to statistics, at this stage
The municipal sludge of China and the treatment utilization rate of industrial sludge less than 10%, away from the treatment utilization rate in such as U.S. of developed country
60%~70% differs greatly.In sewage disposal gross investment, the cost of sludge treatment facilities accounts for 50%~75%.And state
The annual expense for being used for Sludge landfill of family is about 50~100 yuan/ton or so, and by knowing above, China produces 25,000,000 within 2009
The sludge of ton, then total cost is about 125000~2,500,000,000 yuan, counts 1,200,000,000~2,500,000,000 yuan.So exploitation is new, advanced
Technology, effectively process sludge disposal, be allowed to turn waste into wealth, and not damage to the environment, be detrimental to health, open up environment friend
Good road, it is target that we persevere to go on the track of sound progress.
Activated sludge process is current dirty water living creature processing technique most widely used in the world, but its drawback is to produce greatly
Activated sludge more than the Retained of amount.These residual active sludges usually contain a certain amount of poisonous and harmful substance (such as parasitic ovum, cause of disease
Microorganism, heavy metal) and not stabilized organic matter, if not carrying out appropriate treatment with disposal, it will environment is caused directly
Connect or potentially pollute.Activated sludge is micropopulation and organic substance that they are depended on and the general name of inorganic substances.It is micro-
Biocenose mainly includes bacterium, protozoan and algae etc..Wherein, bacterium and protozoan are two main major classes.Activity
Sludge from the appearance, like wadding suede particle, is referred to as biological floes, and its particle diameter is typically in the range of between 0.02-0.2MM.City is dirty
The treatment and disposal of aquatic organism treatment plant excess sludge are a more stubborn problems.Its processing cost accounts for sewage treatment plant
The 25%~40% of overall running cost, even as high as 60%；The sludge mesophilic anaerobic digestion technique for generally using, has reaction
Speed is slow, and residence time of the sludge in pond is long, and tank volume is huge, and operational administrative is complicated, and methane content is low in aerogenesis
Shortcoming.During anaerobic sludge digestion, sludge hydrolytic is rate-limiting step.Using certain pretreatment mode, cell membrane can be made
Rupture, cell inclusion dissolution accelerates the hydrolytic process of sludge.So as to reach shortening digestion time, digestion pool volume is reduced, carried
The purpose of methane production high.At present, the method both at home and abroad on sludge cell wall breakage technology has Physical and chemical method, Physical
There are heat treating process, high-pressure injection method, ultrasonication method, freezing processing method, irradiation method；Chemical method has alkali process method, ozone oxygen
Change method etc..Using different broken wall skill wood, the decomposition of cell in sludge and the release of intracellular organic matter can be promoted, improve sludge
Digestic property, accelerate digestion rate, improve gas production.In engineer applied, according to actual needs, new residue is developed dirty
Mud cell wall breaking technology is still the direction of primary study from now on.However, sludge moisture content is big, dried carbon high cost, sludge money
Sourceization still faces huge problem.
Comminution technology has the low feature of efficiency high, energy consumption, and the industry such as mine, cement row are mainly used at present.Mill equipment
It is the key equipment in rock processing, rock processing is ore to be extruded using energy, impacted and is ground, makes to have in ore
Mineral monomer cleavage is used, beneficial to the process that the next stage is sorted.Broken is to carry out extruding to ore using mechanical energy to make its broken
Split, ore grinding is to make ore fragmentation using impact, grinding, degrade and reach cleavage.According to theory of comminution, reached by the way of broken
Less than the energy that same granularity is consumed is reached by the way of ore grinding, this is also usual engineering to the energy that a certain granularity is consumed
Employed in " much broken and lessmill " scheme origin, this is considered from the consumption of energy.Semi-autogenous mill is part profit
With ore itself, the equipment of ore grinding is partly carried out as milling medium using steel ball, from the viewpoint of energy effective utilization, using half
Autogenous tumbling mill ore grinding, energy consumption is comparing high.But semi-autogenous mill operation in small, broken bits, screening operation, ore transhipment link in instead of, make
Flow shortens, and reduces dust generation, and generally speaking investment is saved, and operating cost reduction, effect on environment is small.Meanwhile, ore
Degrade grinding mainly by ore itself, steel ball consumption is low, and the chemistry or Electrochemical forces to follow-up flotation operation are small, thus more
Cause the concern of people to get over.Ball mill is the equipment for carrying out ore grinding as milling medium using steel ball, is also most universal, most logical
Grinding attachment, in recent years, with the increase of mine capacity and semi-autogenous mill specification, the specification of ball mill also increases quickly.
Chinese mugwort Sa grinding machine is a kind of fine grinding equipment invented by the MountIsa ore deposits of Australia, for the Pb-Zn separation of the ore deposit.This kind grinds
Machine is to make mineral cleavage using the level principle that agitation grinding is degraded at a high speed, and its product granularity P80 can reach 7 μm.Ai Sa grinds
The power level of machine is very big, and up to 350kW/m3, the milling medium that Chinese mugwort Sa grinding machine is used is ceramics, river sand, slag etc..In the world
First Chinese mugwort Sa grinding machine (M3000) put into operation in 1994 in MountIsa Lead-zinc concentrators, to current, existing nearly 20 Chinese mugworts
Sa grinding machine puts into operation, is respectively used to the recovery of the mineral such as gold, zinc, platinum.When micron or submicron order is crushed to, with meal or
Fine powder is compared, and the specific surface area and specific surface energy of superfines rapidly increase, therefore in Jet Crushing, as granularity subtracts
It is small, subparticle reunite mutually (formed second particle or three particles) trend between increase, in certain pulverization conditions and
Crush under environment, by after certain grinding time, ultra-fine grinding is in the homeostasis process crushed-reunite, in this feelings
Under condition, the speed that Jet Crushing particle diameter reduces tends to slow, even if extension grinding time (continuing to mechanical stress), thing
The granularity of material is likely to no longer reduce, or even the trend of " thicker " (soldering) occurs.This is the topmost spy of Jet Crushing
One of point.The raw meal particle size that Jet Crushing occurs when this crushing-reunion is balanced is referred to as " the crushing limit " of material.
Certainly, the crushing limit of material is relative, its applying mode (or species of size reduction machinery) and efficiency, crushing with mechanical force
The factors such as mode, disintegrating process, crushing environment are relevant.
However, such as granularity, hardness, toughness, elasticity and water content etc. huge with ore properties difference in sludge cell,
Traditional grinding apparatus are difficult to the high-efficiency wall breaking of cell.Therefore, how design is adapted in ripe comminution theoretical foundation
In sludge cell high-efficient broken wall unit, grinding apparatus advantage, reducing energy consumption, reduces cost are given full play to, realize that sludge is given birth to
The high-efficiency wall breaking reduction sludge moisture content of thing component, and realize the high-efficiency comprehensive utilization of sludge resource, for solve China or even
World's water treatment problems are significant.
