Description
Technical field
The invention belongs to black-odor riverway Treatment process fields, are related to a kind of automatic method and device for removing pipeline deposit,
The automatic method for removing pipeline deposit is responsible for suitable for multichannel more particularly to a kind of.
Background technique
As rapid urban and the density of population are continuously increased, river water environmental problems are increasingly highlighted, most cities
Black-odor riverway is developed into river.Black-odor riverway problem seriously affects nearby residents quality of life, city image generation.River
The black smelly origin cause of formation is other than leading to river channel ecology system destruction due to urban construction, and most importantly pollutant directly enters river and causes
External source pollution.
In existing black-odor riverway Treatment process, sewage interception along river, bed mud dredging, restoration of the ecosystem, the technologies such as clean water diversion
It is widely used, but since each technological means is there are respective limitation, is difficult to solve the problems, such as that river is black smelly in a short time.
Sewage interception along river, which refers to, lays wastewater interception pipe along river two sides, by it is originally in line enter river sewage access cut dirty pipe
Road, and it is delivered to sewage treatment plant, mitigate the in line impact to river water quality of sewage.But interception project implement engineering cost compared with
Height, implementation cycle are longer.After the completion of interception project, since the sewage of rain dirt hybrid junction accumulation is in rain in combined sewage and municipal pipeline
It can put river by pumping plant driving and enter river, influence river quality of water environment again.
Bed mud dredging is to blow the mud for depositing river bed using mechanical equipment to stir into the watery of muddiness, and transport extraction.Clearly
Deposit technique can reduce the endogenous pollution in river, but improper for the sludge handling of extraction be easy to cause secondary pollution.
River corridor restoration refers in river land-based area control line, is meeting the rivers basic training such as flood control, water drainage and diversion
On the basis of energy, urban river water ecosystem restoration is promoted by artificial reclamation activities, constructs healthy, complete, stable urban river water
The activity of the ecosystem.But the technology to black-odor riverway renovating effect there are limitation, rainfall day put river with pumping plant, pollute
Object can destroy river channel ecology system back into river.

The flow of meter is 3 ~ 6 times of dry flow sewage amount), flow velocity is lower in pipeline when dry days sewage transport, and dirty water pollutant can be in pipe
It is deposited in road.For separate flow system, the problems such as due to rain dirt hybrid junction, dry flow sewage enters storm sewer, and sewage passes through rainwater
The dirty pump that cuts of pumping plant is delivered to sewerage；Many drainage systems are in high water level operational mode, and rain pipe caliber is pressed 3 ~ 5 years
Return period designs (i.e. pipe design conveying capacity is tens times of dry flow sewage amount or more), and caliber is larger, and dry flow sewage is in rain
Flow velocity is lower in waterpipe, and polluter is deposited in tube bottom.Since system high water level is run, tradition connects the water that interim water pipe rinses
Stream impulse force has been consumed in 1m at the pipeline access, and mud is difficult to be washed, even if the deposit that origin or beginning is taken up by instantaneous flow
It can be deposited again in subsequent main pipe；It is only 100m that external high-pressure water pipeline flushing device maximum, which rinses range, and Chinese large-sized
Sewerage system main pipe length generally drains conveying main pipe longest up to 55km more than 1km, such as Shanghai City large size.Therefore, it opens
