Description

A kind of old town black-odor riverway governing system
Technical field
The utility model is related to a kind of old town black-odor riverway governing systems.
Background technology
With industrialization, the progressively quickening of Development of China's Urbanization, the change of population collection, underlying surface causes Regional Water Environment pressure Power gradually increases, and the point-source pollutions such as rainwash pollution of area source and section dirty not perfect sanitary sewage brought that rainfall generates enter River causes the pollution of river to be on the rise, and river channel ecology function is increasingly degenerated and lost.Most of river occurs seasonal or normal The black and odorous water of year property.Especially old town river, civilian infrastructure construction fall behind, and transformation and upgrade paces are slow, exist very Cause the black smelly pollution sources in river more, including rain dirt pipeline hybrid junction, misconnection and miss, cell balcony, garage residential sewer are direct Be discharged into river, along the street carwash shop, sewage from catering business concentrate exhaust emission, automobile, roadway pollution, along the river public lavatory septic tank leak It pollutes, along the river garbage pool leachate contamination etc..
The improvement of black-odor riverway at present includes cutting dirty transformation, bed mud dredging, restoration of the ecosystem, water transfer running water etc..Cut dirty transformation Enforcement difficulty is big, most rain dirt pipeline hybrid junction, misconnection and misses remote because building, and investigation is difficult, so being arranged using end Mouth river closure mode is more, but only can guarantee that dry season sewage does not enter river and the part rainy season sewage that shuts off, it is difficult to solve most of mixed flow Sewage enters the problem of river.The mode of bed mud dredging is also unsatisfactory in the effect that city uses, and water quality cannot ensure after dredging. Water transfer running water mode with the in vivo pollutant of water simply also has been transferred to downstream, do not degraded effectively, and adjusted The cost of water mode is also higher, and some areas are even adjustable without clear water.Restoration of the ecosystem is in treating city black foul river, effect There are hysteresis quality and chronicity, simple restoration of the ecosystem measure can not improve water quality well, and often landscape effect is more than Its clean-up effect administers initial stage in black-odor riverway, is even more difficult to recover water ecosystem.
At present, black-odor riverway is administered very urgent, however is limited to source and is difficult to thoroughly cut dirt, and black-odor riverway improvement is difficult to Recover stable aquatic ecosystem, the management goal of expected " water is clear " is not achieved.
