Description

A kind of production unit of sewage sludge biomass environment-friendly fuel
Technical field
The utility model relates to field of sludge treatment, exactly is meant a kind of production unit of sewage sludge biomass environment-friendly fuel.
Background technology
By in by the end of June, 2010, whole nation accumulative total is built up 2389 of urban wastewater treatment firms, and sewage treatment capacity reached for 1.15 billion cubic meter/days.At present, national town sewage processing project of building reaches 1929, about 4900 ten thousand stere/days of general design ability.Be accompanied by the urbanization process of China and continuing to increase of environment protection dynamics, sewage work can increase in the quite a long time fast.Along with the quick raising of wastewater treatment in China ability, sludge quantity also significantly increases synchronously, and by the end of the year 2010, the wet contracts amount of mud (water ratio 80%) of national urban wastewater treatment firm breaks through 3,200 ten thousand tons.Contain hazardous and noxious substances such as a large amount of pathogenic agent, heavy metal substance in the mud, the mud that does not obtain safety, environmental protection treatment disposal is bigger to the harm of environment, also easy generation of secondary pollution.The environment mud problem that mud produced becomes increasingly conspicuous, and has caused great potential safety hazard, environmental stress and economical load.
At present, the processing of mud is main towards three aspects development: the one, and stabilization through means such as compost, digestion, makes no longer further degraded behind the sludge disposal, avoids secondary pollution; The 2nd, innoxious, remove pathogenic agent, curing, stabilizing heavy metal ensure ecological security; The 3rd, resource utilization is carried out comprehensive utilization of resources when handling mud.
Landfill---sludge digestion is after the mode that landfill is present domestic and international normal employing is carried out in dehydration again.Landfill less investment, big, the instant effect of capacity; But the place should not be sought; Mud transportation and landfill yard construction cost are higher, the landfill finite capacity, and the seepage of objectionable constituent may cause groundwater pollution; The health of landfill yard, foul smell can cause secondary pollution, and the nutritive substance that contains in the mud can make a large amount of pathogenic bacteria procreations etc.If the problem of most critical is mud and directly gets into the engineering accident that landfill yard will cause landfill yard without pre-treatment.In recent years, partly landfill yard has begun to reject the mud entering, so the mode of landfill disposal disposing sludge will be faced with restriction.
The soil utilizes---and utilize plant nutrition nitrogen in the mud, phosphorus, potassium etc., mud is processed fertilizer or soil improvement agent, be used for afforestation, soil improvement, agricultural.Heavy metal in the mud belongs to the pollutant component that can not degrade, and the speed of in soil, moving is extremely slow, though mud through compost, the continuous accumulation that heavy metal wherein also can be in soil.See that from the whole country the disposal options of soil utilization also will face strict restriction day by day.
Material of construction utilizes---and utilize inorganicss such as silicon in the mud, aluminium, iron, calcium to process material of construction such as cement, brick, pottery, substitute existing resources consumption-type building materials.The building materials utilization of mud has system light ceramic, system fusion sytull, produces cement etc.But brick-tile industry is as a kind of sunset industry, and industry integral body will be faced with transition, so, rely on the material of construction mud that is used to dissolve also will face adverse conditions.
Burn---utilize incinerator with the dewatered sludge heat drying, use the organism in the high temperature oxidation mud again, make mud become a small amount of ashes.Burning can realize maximum minimizing with mud; All pathogenic agent all can be killed, and toxic pollutant is oxidized, much lower in the heavy metal specific activity mud in dust and the lime-ash.But the sludge incineration investment is big, processing costs is high, organic compound combustion produces highly toxic substances such as Dioxins.Therefore, sludge incineration disposal options is unsuitable to be promoted on a large scale.
To the present situation that present domestic sludge treatment is disposed, need a kind of production unit of the environment-friendly fuel of sewage sludge biomass cheaply badly, to realize minimizing that sludge treatment disposes, innoxious, stabilization and resource utilization.
The utility model content
To above-mentioned defective; The technical problem that the utility model solves is to provide a kind of production unit of sewage sludge biomass environment-friendly fuel, realizes minimizing that sludge treatment disposes, innoxious, stabilization and resource utilization, solves the mud secondary pollution problem effectively; And obtain biomass environment-friendly fuel; Can replace coal to get into boiler combustion, when remedying the sludge treatment cost of disposal, also can solve the energy starved social concern effectively.
In order to solve above technical problem; The production unit of the sewage sludge biomass environment-friendly fuel that the utility model provides; Comprise pretreatment pool, combined reaction pond, sludge press filtration machine, drying machine and tablets press, said pretreatment pool, combined reaction pond, sludge press filtration machine, drying machine and tablets press are linked in sequence through transport establishment successively.
Preferably, said pretreatment pool is provided with biological deodorizing device.
Preferably, said combined reaction pond is provided with biological deodorizing device.
Preferably, said drying machine is provided with biological deodorizing device.
