The invention discloses a
processing system and
processing technology for removing
river pollution bottom
silt in a central
urban area. The
processing system comprises a multi-functional desilting vessel, a
silt storage and transportation vessel and a
silt dehydrating and
drying vessel, wherein the multi-functional desilting vessel, the silt storage and transportation vessel and the silt dehydrating and
drying vessel are communicated through pipelines. The multi-functional desilting vessel comprises a
machine body, wheel-type supporting legs, a coarse
garbage collection tool /
reamer tool arranged at one end of the
machine body and a first hydraulic
system used for driving the coarse
garbage collection tool /
reamer tool. The silt storage and transportation vessel comprises a storage and transportation vessel body, positioning piles and a silt cabin, wherein a plurality of stirrers are further arranged in the silt cabin, the silt cabin is connected to the silt dehydrating and
drying vessel through a pipeline. The silt dehydrating and drying vessel comprises a dehydrating and drying vessel body, positioning piles, a second hydraulic system, a stirring cabin, a chemical feed device and a drying device. According to the processing technology, a mobile processing
station is adopted, all the devices are arranged aboard for operation, and therefore
land resources are not occupied. Moreover, a processing method is simple, a processing period is short, the silt processing is thorough, and
operability is high.
