Description
Technical field
The utility model is related to a kind of interim disposal systems of dredged sediment.
Background technology
China is populous nation, and the urbanization process in China has obtained development at full speed since 2000, and in future
Longer period is among Process of Urbanization Construction.With the development of urbanization process, many urban issueses are also brought.In recent years
Come, the urban issueses such as city black and odorous water, urban sewage piping lane impeded drainage emerge in an endless stream.Current governmental is to urban water-body environment
And drainage problem pay attention to day by day, the relevant items such as black and odorous water dredging and the transformation of city piping lane are increasing.Black and odorous water is clear
In the work progress of silt and city piping lane transformation project, substantial amounts of black foul sewage mud will be generated in the short period of time.It is a large amount of black smelly
Sludge concentrates generation in the short period of time, and how quickly, safe, economic the disposal for completing the black foul sewage mud of high-volume is one
Problem.
The processing of sludge at present generally requires dehydration, desiccation minimizing processing, minimizing treated sludge with low moisture content
It burned, filled again, cement mixes the final processing or disposal such as burning.Above-mentioned black smelly moisture percentage in sewage sludge often more than 80%,
Sludge treatment capacity is chiefly used in meeting the processing that itself generates sludge in sewage treatment plant in general city, lacks the production of dredging process
The processing capacity of primary sludge；But more than 80% sludge of moisture content can not also carry out landfill disposal.Sludge reduction processing is carried out to set
It applies or the construction of the conventional sludge treatment facility such as landfill yard can not also be completed within a short period of time, and lack economic feasibility.
The dredged sediment generated in current country's associated construction project lacks effective processing approach, and substantial amounts of sludge " is changed
Whole is zero ", is often discarded in isolated area by all means by construction party, and there are larger safety and environmental hazards.
Using sludge is quenched, is pumped to after mixing in sludge dewatering pipe, sludge dewatering pipe has certain the utility model
Bearing capacity can stack；Sludge dewatering pipe is deposited on the bed course of special designing, on the one hand prevents percolate from passing through osmosis pollution
Underground water, while can also meet the collection of percolate in sludge, is conducive in interim disposal process that sludge oozes in geotechnological cloth bag
The discharge in a organized way and centralized processing of filtrate；It banks up and sets air film canopy closed outside the sludge dewatering pipe of completion, prevent black foul sewage
The foul gas uncontrollable discharge that mud generates；Air film canopy is supported and taken a breath by air blast, efflux gas carries out in a organized way
Fume treatment.
Dredged sediment is disposed temporarily by this way, economical good, it is excellent that construction is fast, and environmental emission is up to standard etc.
Point disclosure satisfy that the standardization for the short time high-volume sludge that the dredgings engineering project such as black and odorous water and piping lane transformation is related to is concentrated
Disposal, it is therefore prevented that related arbitrarily heap abandons the appearance of phenomenon, it is expected to reduce sludge environmental pollution and security risk.
