Description
Technical field
The utility model belongs to technical field of sludge treatment, be specifically related to a kind of sludge modification and the dewatering integrated device of steam heating type screw press, this device can realize the conbined usage of the modification of mud medicament and mechanical dehydration, can be used for dispose of sewage factory's mud, riverway sludge, dangerous solid waste etc.
Background technology
Along with the operation of large amount of sewage treatment plant runs, sludge yield will significantly increase.According to the literature, within 2011, China's total amount of sewage discharge reaches 482.4 hundred million tons, produces excess sludge (dry mass) 8,470,000 tons, and the surplus sludge volume of annual discharge is with the speed increase of about average annual 10%.In addition, in biological wastewater treatment process, micropopulation contacts with the organism in sewage, and the composition that picked-up organism in water can be decomposed carries out growth and breeding.The glue plumage of hyperplasia forms extracellular polymeric that bacterium can secrete with self, remaining suspension solid in aqueous phase, thread fungus, fungi, protozoon and divalent calcium, magnesium ion in this process, common gathering connects to the size about mud glue plumage of hundreds of microns, its short texture, water ratio is high, and have huge surface area and highly hydrophilic, with a large amount of Bound moisture, sludge treatment difficulty is caused to increase.Therefore, the process of mud day by day becomes with disposal the important indicator examining sewage work to run performance.
The moisture percentage in sewage sludge that sewage work discharges is up to 95% ~ 99%, and such sludge volume is very huge, can reach the decades of times of solid volume contained by it, and character is very unstable, very easily degenerates, and is unfavorable for transport and disposes.China " household refuse landfill sites Environmental capacity standard " (GB16889-2008) specifies, municipal sewage sludge only has water ratio after treatment to drop to less than 60%, just can enter landfill yard.But China's municipal wastewater treatment plant generally adopts mechanical system to carry out sludge dewatering at present, and dewatered sludge water ratio, generally 75% ~ 85%, obviously can not meet afore mentioned rules.
Chinese patent CN101811814A discloses a kind of mechanical dehydration treatment method for sludge modification.By first to water ratio be add dewatering agent, ferrous sulfate, lime and reodorant in the primary sludge of 80 ~ 85% after carry out stirrings formation primary sludge.Then in primary sludge, add the water accounting for primary sludge weight 30 ~ 50%, continue to stir formation mud mud oar.Then mud mud oar is processed in primary crusher, make the little liquid pearl in mud mud oar assemble the large drop of agglomerating formation and play demulsification, remove the solid impurity in mud mud oar simultaneously.Subsequently the mud mud oar after primary crusher process is exerted pressure in pressure filter, make mud mud oar generation solid-liquid separation form sludge cake.Finally evenly stacked by sludge cake, stacking is highly 30 ~ 50cm, and natural mummification 48 ~ 72 hours, obtain the dewatered sludge mud cake that water content is 20 ~ 30%.This invented technology flow process is complicated, and sludge dewatering needs the longer time (more than 2 ~ 3 days).
Chinese patent CN103332849A discloses a kind of novel deeply dehydrating sludge amendment, first mix the sludge conditioner A made mix by mass ratio 5 ~ 30% active carbon powder, 30% ~ 70% flyash, 5% ~ 30% calcium lime powder with mud, amendment A add-on accounts for 1% ~ 20% of sludge quality, mechanically mixing is carried out with the mud after amendment A nurses one's health again by by adding the solution of 10 ~ 1000g/L that 1% ~ 20% dimerization ferro-aluminum and water is mixed with, then pump into deep dehydration device for sludge with sludge pump, carry out mechanical dehydration.This invention amendment adds complex procedures, and amendment dosage is comparatively large, mud decrement DeGrain.
Chinese patent CN103030258A discloses a kind of sludge deep dehydrator and dewatering.Carrying out pre-treatment by first mud being delivered to concentration basin, then sending in conditioner and carrying out medicament conditioning, then be delivered in diaphragm filter press and carry out press filtration, thus complete deeply dehydrating sludge operation.These invention process structures are more, and laid down cost is larger.
Chinese patent CN202390301U discloses a kind of mechanical type sludge rapid dewatering system.This system is made up of broken stirring system, delivery system and belt filter press, is combined, dewaters to mud by medicament modification with belt press filtration.This invention can realize mud fast dewatering, but structure is not compact, and floor space is larger.
Chinese patent CN101723572A discloses a kind of method for modifying, filter-pressing and dewatering sludge.First in mud, add properties-correcting agent carries out modification to mud, then with pump, mud is sent into special plate-and-frame filter press.After mud is filled, stop charging, start filter-press dehydration.This invention can not continuously feeding, continuous discharge, cause its processing power limited.
Above sludge deep dehydrator and method solve the problem of sludge reduction and stabilization.But sludge deep dehydrator still has following three aspects to need to be improved further.One, deep dehydration system for sludge is arranged compact not, and floor space is large; Its two, partial sludge dewatering unit can not continuously feeding and discharging, and processing power is limited; Its three, deeply dehydrating sludge process is more complicated.
