Abstract

The invention discloses a processing method for preparing bricks by utilizing urban domestic sludge, which relates to the processing and the utilization of the urban domestic sludge. The processing method comprises the following steps: granulating and drying the sludge for aging; uniformly mixing aged granular materials with shale or clay or coal slag or building rubbish according to the proportion by weight; after the mixing, adding an amount of water for preparing brick blanks and continuing stirring and mixing; preparing the blanks; sintering the blanks; and preserving heat and cooling the blanks to obtain the bricks. The invention greatly saves resources and provides an active sludge processing and utilizing scheme. Some of the strength indexes of the prepared bricks even exceed those of the bricks prepared by ordinary processes. During roasting, for the condition that tail gas generated in the process of roasting the sludge bricks contain more sulfur and chlorine ingredients, a combined desulphurizing and deodorizing technology inside and outside a furnace is used, namely, the limestone is added in to a burning furnace, and water is sprayed to the tail gas under a sealing condition, thus a desulphurizing reactor does not need to be arranged on a tail part so as to ensure that smoke gas reaches an emission standard.

Description

Utilize the working method of bricks from urban domestic sludge
Technical field
The present invention relates to the processing and the utilization of municipal sludge, relate in particular to city domestic sewage processing toe-in and close, utilize the method for the making brick from sludge of its generation.
Background technology
Along with urban wastewater discharge is increasing, the mud of alluvial is more and more, and sludge treatment is difficulty very.Existing method for sludge treatment adopts buried processing mostly.Because various source of pollution are heavier in the mud, imbed the underground pollution bigger to underground water generates for a long time, the soil of imbedding mud can't plant utilization, causes the land resources waste, and overflowing to local people's life of various foul smell caused bigger influence simultaneously.
Summary of the invention
The present invention is directed to prior art problems, provide a kind of and city domestic sewage processing toe-in to close, utilize the mud of its generation to make the working method of utilizing bricks from urban domestic sludge of the higher brick of intensity.
Technical scheme of the present invention is: it may further comprise the steps:
1), the mud of output in the city domestic sewage treatment system is carried out granulation processing, dry processing, to water content be 25~30%, ageing;
2), with the granular material after the ageing and shale or clay or cinder or the building waste after pulverizing according to 1: 3~4 weight ratio uniform mixing; After the mixing, add the water of brickmaking base amount, continue to mix;
3), base;
4), sintering; Adobe is dropped into tunnel furnace, establish preheating zone, roasting band, insulation belt and cooling zone in the tunnel furnace, wherein roasting band temperature is at 870 ℃~920 ℃, and roasting time is 16~48 hours;
5), the insulation, the cooling, make.
In roasting process, in the incinerator of tunnel furnace, drop into Wingdale.
On the smoke evacuation pipeline of tunnel furnace, be provided with waterworks.
Tradition brickmaking is main raw material with soils such as clay, shale, Mineral resources mainly, need expend a large amount of resources on the one hand, and simultaneously, the mud discharging in the municipal effluent also is insoluble environmental problem.The present invention is one of raw material of brickmaking with the mud in the city domestic sewage, and this has saved resource greatly, has also improved a kind of positive sludge treatment simultaneously, has utilized scheme.The outward appearance basically identical of brick that makes and common brick; Because mud is through having added flocculation agent PAC, so mud has very strong viscosity, its intensity index even some indexs surpass the brick that ordinary process makes.When roasting, to containing the situation of more sulphur and chlorine component in the tail gas that produces in the sludge brick roasting process, use the inside and outside combined desulfurization deodorization technology of stove, promptly in incinerator, add Wingdale, and tail gas sealed water spray, this can save afterbody dress desulphurization reactor, thereby makes flue gas reach emission standard.
Embodiment
The present invention processes according to the following steps:
1), the mud of output in the city domestic sewage treatment system is carried out granulation processing, dry processing, to water content be 25~30%, ageing;
2), with the granular material after the ageing and shale or clay or cinder or the building waste after pulverizing according to 1: 3~4 weight ratio uniform mixing; After the mixing, add the water of brickmaking base amount, continue to mix;
3), base;
4), sintering; Adobe is dropped into tunnel furnace, establish preheating zone, roasting band, insulation belt and cooling zone in the tunnel furnace, wherein roasting band temperature is at 870 ℃~920 ℃, and roasting time is 16~48 hours;
5), the insulation, the cooling, make.
When roasting, to containing the situation of more sulphur and chlorine component in the tail gas that produces in the sludge brick roasting process, use the inside and outside combined desulfurization deodorization technology of stove, main by two technique means realizations once, the one, in roasting process, in the incinerator of tunnel furnace, drop into Wingdale.The 2nd, on the smoke evacuation pipeline of tunnel furnace, be provided with waterworks.
