Description
Technical field
This utility model belongs to field of sludge treatment, it is specifically related to the complete processing system of oily sludge dehydration-mummification, in particular for dehydration decrement, resource and innocuity disposal systems such as the oil-containing dross produced in petroleum chemical industry sewage disposal process, pond bed mud, tank bottoms mud, biochemical sludges.
Background technology
In sewage disposal, the effect of microorganism makes polluter transfer to solid phase from aqueous phase, thus creates mud.Mud is the side-product that the volume produced in sewage disposal process is maximum, and moisture content is high, be difficult to dehydration, and content of organics is many, and character is unstable, and easily corruption is smelly, and hazardous contaminant content is high, containing pathogen and parasitic ovum, threatens human health.
Petroleum chemical industry, because containing the Organic substances such as more oil content in sewage, therefore generally can produce substantial amounts of mud in sewage disposal process, mainly include tank bottoms mud, oil interceptor bed mud, oil-containing dross, biochemical sludge etc..At present, oneself oily waste water species (national environmental protection portion, National Development and Reform Committee's the first command in 2008) of being put in " National Hazard refuse catalogue " of the mud that petrochemical industry refinery industry produces, " country's promotion law on cleaner production " and " solid waste environmental pollution prevention and control method " also require that and oily sludge must be carried out harmless treatment.
Along with increasing substantially of sewage load handling rate, mud has become as one of stern reality difficult problem of puzzlement sewage treatment plant, and safe and harmlessization only achieving mud is disposed and can be only achieved the purpose eliminating pollution.In the sewage treatment plant that China has built up, have sludge stabilization treatment facility is less than 1/4, sludge treatment technique and corollary equipment the most perfect be less than 1/10.Major part sewage treatment plant does not all have the auxiliary facility of Treatment of Sludge." 12 " period, China's newly-built specific resistance to filtration scales 5,180,000 tons/year (in terms of dry mud).Visible, that Treatment of Sludge is increasingly subject to great attention.
The final purpose of Treatment of Sludge is to realize specific resistance to filtration to reach minimizing, stabilisation, innoxious, resource.The present stage sludge treating method of sewage treatment plant is broadly divided into quenched sludge dewatering (pretreatment), two stages of sludge drying (deep dehydration):
(1) at sludge dewatering pretreatment stage, generally moisture percentage in sewage sludge can be down to about 80%.Applying more mud dewatering method at present is filter press, belt filter press, centrifuge.The problems such as pressure filter is relatively big due to its actuating pressure, and the minimizing degree of mud is the most obvious, is therefore widely used, but filter press exists discontinuous operation, and treating capacity is less, and operation is complicated；Belt filter press pressure can not reach the degree of filter press, but its work is continuously, management control is simple, stability is preferable, the most a lot of sewage treatment plants all select belt filter press to be dehydrated, pressure filter is because using pressurization filter-cloth filtering mode, therefore the oily sludge produced for petrochemical industry, easily dirty stifled；Currently for oily sludge, especially at petroleum chemical industry, commonly used three-phase separator processes, such as Zhenghai refinery, Luoyang Petrochemical, oil of SPC, Jinan Refinery etc., but dehydrating effect is the most undesirable, main performance: after de-, greasy filth moisture content is still between 75%～85%, after dehydration, in aqueous phase, suspension content is high, and centrifuge operation expense is high.Additionally, be dehydrated greasy filth by centrifugation apparatus, it must also be noted that the centrifugal factor of centrifuge, the balance of the greasy filth time of staying and regulation etc., condition is harsher.
(2) in sludge drying (deep dehydration) stage, generally moisture percentage in sewage sludge can be reduced to less than 30%, be to solve mud finally to process the key link.The main heat drying technology used.Heat drying is a kind of to utilize heat energy by the process technique of moisture rapid evaporation in mud, according to source and the difference of mode of heating of heat energy, fluidized drying, superheat steam drying, partition can be divided into be dried, microwave drying, infrared radiation drying etc..Wherein fluid bed mummification, rotary drum mummification and disc type mummification are more common, but its energy consumption is big, and investment operating cost is high, and operating technology is high.
The final processing mode of mud mainly has: burn (individually burn, steam power plant is collaborative process), security landfill, sanitary landfills, Land_use change, building materials utilize.For urban sewage system mud, owing to its calorific value is low, the most commonly used land-fill method processes, and floor space is big, and easily causes the problems such as pollution arable land during landfill.And for oily sludge, disposal options is preferably burning, secondly for security landfill, other disposal options is all forbidden.
