Description
Technical field
The present invention relates to a kind of sludge treating system, more particularly, relate to a kind of high-efficiency full-closed sludge treatment system and method thereof.
Background technology
The mud that present mud, especially municipal sewage plant produce adopts landfill, burning, coastal waters to topple at home usually or modes such as composting, burned brick are handled.To be fired into common brick after the sludge treatment drying with after clay mixes as the unique sludge treatment in Guangzhou factory, this is present sludge treatment BOT project the biggest in the world.
Conventional art is not good to the treatment effect of mud at present.Therefore, how to solve sludge treatment, especially sludge of sewage treatment plants is a problem demanding prompt solution.Do not have one at present as yet treatment process be simple, fixed investment is few, take up an area of less, processing cost is cheap, complete deodorization, non-secondary pollution, recycled total system of the material after the processing and method.
Summary of the invention
A technical problem to be solved by this invention provide a kind of high-efficiency full-closed, need not composting, fixed investment few, take up an area of less, processing cost is cheap, complete deodorization, non-secondary pollution and handle after material a kind of high-efficiency full-closed sludge treatment system that can carry out recycle, this a kind of high-efficiency full-closed sludge treatment system has been realized minimizing, stabilization, harmless chemical combination and the resource utilization of mud.
Another technical problem to be solved by this invention provides a kind of method that realizes above-mentioned high-efficiency full-closed sludge treatment system.
In order to solve the problems of the technologies described above, the present invention has adopted following technical scheme:
On the one hand; a kind of high-efficiency full-closed sludge treatment system; it comprises sludge bin, calcium lime powder storehouse, stirrer, worm conveyer, slaking silos, the organic warehouse of powdery, nodulizer and finished bin; the calcium lime powder in the mud of described sludge bin and calcium lime powder storehouse stirs formed mixture through stirrer and flows to slaking silos by worm conveyer, and said mixture in the slaking silos and the powdery organism in the organic warehouse of powdery flow to finished bin by worm conveyer after granulating by nodulizer again after stirrer stirs.
On the other hand, a kind of method that realizes the described system of claim 1, it may further comprise the steps:
2.1 earlier the mud of sludge bin is recently mixed by 2: 1 weight with stirrer with the calcium lime powder in calcium lime powder storehouse, more above-mentioned mixed mixture is delivered in the slaking silos by worm conveyer;
2.2 the mixture in the step 2.1 is when thermopositive reaction takes place in digestion and the water of unslaked lime in said mixture and mud in slaking silos naturally in slaking silos, when the temperature in the slaking silos is elevated to 78 ℃-82 ℃ and pH value rapidly greater than 12 and this pH value when keeping more than 3 hours greater than 12, make the water evaporates and the naturally cooling of mud;
2.3 after the water ratio of the mixture in slaking silos is reduced to 28%-32%; it is above-mentioned water ratio the mixture of 28%-32% and the particulate materials of making water ratio 8%-12% after powdery organism in the organic warehouse of powdery recently mixes by 1: 1 weight with stirrer again with nodulizer; then, above-mentioned particulate materials is delivered to worm conveyer become organic fertilizer in the finished bin and get final product.
As further improvements in methods, in step 2.2,, make the water evaporates and the naturally cooling of mud when temperature in the slaking silos is elevated to 80 ℃ and pH value rapidly greater than 12 and this pH value when keeping more than 3 hours greater than 12 to the technical program; In step 2.3, after the water ratio of the mixture in slaking silos reduced to 30%, being above-mentioned water ratio 30% mixture recently mixed by 1: 1 weight with stirrer with powdery organism in the organic warehouse of powdery.
The present invention is owing to having adopted said system and method thereof, so it has following beneficial effect:
At first, mud is mixed with stirrer in proportion with calcium lime powder, be delivered in the slaking silos by worm conveyer, mixture is digestion naturally in slaking silos, the water generation thermopositive reaction of unslaked lime and mud, the interior temperature of slaking silos is raise rapidly, can reach about 80 ℃, pH value reaches more than 12 and keeps more than 3 hours, make the water evaporates and the naturally cooling of mud, thereby can kill the germ of mud, sick worm's ovum, pathogenic agent, elimination stink, heavy metal-passivated comprehensively, reduce the water ratio of mud;
Secondly, the mixture of slaking silos and the material of the organic warehouse of powdery are mixed in proportion with stirrer, and make particulate materials with nodulizer, and deliver in the finished product warehouse by worm conveyer, become organic fertilizer, can pack or direct sale in bulk, reach the purpose of recycling;
Three, the organic fertilizer main component that the present invention produced is mud, powdery organism, lime etc., can be used as fertilizer, owing to contain a large amount of NPKC in the mud
aAnd it is organic, and N, P are based on organic, the trace element that also has simultaneously many plants institute palpus in the mud, can slowly discharge, have long-lasting, and lime is as the natural insecticide of reported first in the world, various pests such as can prevent eliminating aphis, kill the soil germ, its alkalescence can improve slant acidity soil, filter, heavy metal-passivated, improve groundwater quality, river, river, lake water quality, absorbing carbon dioxide generates lime carbonate simultaneously, so organic fertilizer can improve air ambient, the powdery organism has good effect to soil improvement;
Four, in the present invention, do not need to add any chemical agent owing to just add unslaked lime, powdery organism, and do not need to add a large amount of main equipments such as boiler, water extracter, moisture eliminator, so the present invention had not only reduced investment and processing cost but also can not cause secondary pollution, the material after the processing becomes organic fertilizer can recycle.
In sum, that the present invention has is high-efficiency full-closed, need not composting, fixed investment is few, take up an area of less, processing cost is cheap, complete deodorization, non-secondary pollution and handle after material can carry out advantages such as recycle, the present invention has realized sludge reduction, stabilization, innoxious comprehensive treating process of closing resource utilization, the present invention can be country and enterprise saves substantial contribution, save a large amount of land resourcess and sludge treatment expense, promote the Sustainable development of environmental protection industry and recycling economy.
