Description
Technical field
The utility model is related to a kind of portable and fixed urban pipe network sludge reduction processing unit.
Background technology
According to investigation, the existing municipal routine servicing of China has still quoted the tradition of decades.Workman is conserved except tradition
Bamboo chip, strainer, it is artificial twist outside logical, men hoisting, the frequent Frequent Accidents in each metropolitan routine servicing in the whole nation.Shed,
Water clock, natural desiccation cause 2 pollutions of environment.Aqueous high underground sewage sludge severe contamination underground water source, with manpower into
This increase, existing maintenance pattern has allowed municipal administration cost can't bear the heavy load." sea is seen in city " has been many places
The scape of city one.Serious loss is brought to national economy.
Pipe network sludge refers to urban underground water drainage pipe road clear deposit dragged for up during maintenance dredging.In pipeline
It is not smooth that deposit easily causes municipal drainage, and blocking is easily caused to forebay pump when being transported to sewage treatment plant.Enter river with rainwater
Cause the pollution to water body in road.
Backward sludge collection at present, transport, disposal options are increasingly not suitable with the demand of Ecological Civilization Construction, therefore need
Seek a kind of rational specific resistance to filtration scheme.As cleared up not in time, easily cause impeded drainage, trigger ponding and sewage to emit
Overflow, the pollution to water body is caused into river course with rainwater.In the case of current domestic city drainage pipeline networks water drainage scarce capacity,
Ditch mud is cleared up not in time, can aggravate the influence of urban waterlogging disaster." sea is seen in city " is long-term due to " on important place.Lightly
Under " and cause city morbid state.
The strong rainstorms that extreme climate is brought due to pipe network blocking and impeded drainage.Backward draws means clearly.High intensity
Work.Severe operating environment is to cause pipe network to block arch-criminal.
The sludge treatment device research of China is concentrated mainly on the sludge of sewage treatment plant, mainly have vacuum filtering and dewatering,
Filter-press dehydration, centrifugal dehydration, heat drying, natural desiccation several ways.And for the processing of pipe network sludge, studies in China is rare to be related to
And.
For underground pipe network desilting special equipment, China is blank.For associated machines development also in starting
Stage, existing manual work.And semimechanized operation means can not be met because of urban sprawl, population explodes to buried pipe
The pressure that guipure comes.For a long time " on important place.Under lightly " bills due that causes, " sea is seen in city " is the portrayal of present reality.
Because sludge handled by municipal wastewater treatment plant is homogeneous, centrifuge, band machine filter press, plate and frame machine etc. can be passed through
It is dehydrated, and the drainage pipeline sludge components in city are complicated, and containing substantial amounts of house refuse, sand, debris, conventional dehydration is set
It is standby to wear and tear very serious, or even can not be dehydrated at all, to be at least aided with necessary preprocessing means, certainly will so increase a large amount of
Processing cost.So that limited financial fund is too tired to deal with.
Such as belong to the processing mode of high energy consumption using hot drying and processing, its economy is extremely limited, and in operation process
Produce the living environment air quality that substantial amounts of toxic and harmful gas has a strong impact on periphery.
Such as big using natural air drying processing floor space, and environmental Kuznets Curves are relatively difficult should not build urban district in, sludge turns
Fortune cost is higher, and the scraper difficulty of dewatered sludge is also larger.Airborne dust and rainwater weather have a strong impact on surrounding enviroment,
Because drainage pipeline sludge and municipal sewage sludge composition and characteristic are far from each other, therefore processing method indiscriminately imitates root
This is unworkable.
The conventional process disposal options of current pipe network ditch mud are drawn clearly based on artificial, are directly cleared without dehydration, one
As to refuse landfill landfill disposal.
Its workflow is as follows：
1）Sludge band water after drawing clearly is directly stacked at vacant lot, is together transported with rubbish after desiccation；
2）The company of clearing is contracted out to, final outlet is：It is outer be transported to rural area depression and topple over or together mixed with architecture sediment fill out
Bury；
3）Airing field or sludge storage point are transported to, soot landfill is transported to after natural desiccation.
The shortcoming of the conventional process disposal options of pipe network ditch mud is as follows：
1st, cost of transportation is high --- and it is high to clear cost without dehydration；
2nd, secondary pollution is serious --- because the moisture percentage in sewage sludge for drawing place clearly is high（Average about 85%）, directly clear influence rubbish
Surrounding enviroment are made a very bad impression by the normal operation of rubbish landfill yard if through natural desiccation；
3rd, inefficiency --- many people of sewage pumping station needs, which go into the well, manually to draw clearly；
4th, security is poor --- and there is safety issue in workmen's down-hole operation；
5th, landfill cost is high --- and it is the sludge dewatering and landfill cost height that can not be filled that the sludge for having sewage, which is not handled, is filled out
Bury occupation of land big.
