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 device 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.
Clean water diversion is to introduce polluted river channel upstream or neighbouring cleaning by the regulation of water conservancy projects (such as gate, pumping plant)
Water source enhances the diffusion, purification and output of water pollutant to improve the hydrodynamic conditions in river, being capable of rapid recovery water body
It is black smelly, but can not achieve the improvement steady in a long-term of black-odor riverway water quality.
For the black-odor riverway Treatment process applied at this stage there are long construction period, investment is big, and the limitation such as can not take effect in short term
