Abstract
The urban sludge dewatering and solidifying method is for solving the secondary pollution, reducing sludge transporting cost and saving resouce. The technological scheme includes setting sludge inside dewatering chamber; heating sludge to make water contained converted into aqueous vapour and the organic contained gasify; leading out aqueous vapour and waste gas from the dewatering chamber to condensator; condensing aqueous vapour in the condensator into hot water; and leading waste gas from the condensator to the combustion chamber. The treated sludge may be replace available soil source, and this can save transportation cost, save soil and reduce secondary pollution.
Description
Technical field:
The invention belongs to environmental technology field, particularly relate to a kind of treatment process of urban sludge.
Background technology:
Urban sludge refers to the mud attitude waste that produces in urban construction and the communal facility maintenance processes, this type of refuse directly enters municipal drainage piping and river course, to have a strong impact on the drain function in city because of the deposition of solid phase particles, and endanger urban environment because of the release of pollutent wherein.Common outward transport pushes away puts, and has then both caused the waste of land resources also to influence the quality of surrounding environment.
Technology contents:
In order to address the above problem, to the invention provides the municipal pipeline of a kind of reasonable utilization, and reduce the urban sludge dewatering and solidifying method of the wasting of resources.
Technical scheme of the present invention is: at first mud is positioned in the dewatering station; Mud is heated, thereby make the moisture content in the mud be transformed into water vapor, and make the mud gasification; Sucking-off water vapor and waste gas and deliver in the condenser in the dewatering station again, water vapor obtains hot water after the condensation in condenser; Waste gas in the sucking-off condenser is also delivered in the burner.
Advantage of the present invention is: the mud after the processing can substitute existing Tu Yuan, and saves transportation cost, avoids land wastage and restriction secondary pollution diffusion.
Embodiment:
The present invention at first is positioned over mud in the dewatering station.Mud is heated, thereby make the moisture content in the mud be transformed into water vapor, and make the mud gasification.Sucking-off water vapor and waste gas and deliver in the condenser in the dewatering station again, water vapor obtains hot water after the condensation in condenser.Waste gas in the sucking-off condenser is also delivered in the burner.
