Description
Technical field
The present invention relates to river regulation technical field, is used for the high sea of subtropical monsoon climate more particularly to one kind
Rise sheer from level ground the river channel ecology processing system in area.
Background technology
Belong to Northern Hemisphere subtropical monsoon climate in Subtropic of China monsoon climate area, in High aititude weather
Area, made due to the incomplete of urban sewage treatment system part of contaminated water be not collected into factory and office manage in line river course,
Pollution of area source imports river course, the reason such as the in line river course of small towns sewage with rainwash, receives dirt step by step, causes more
Bar river is contaminated, and water quality is bad V classes throughout the year, this cause purifying river water quality, recover river basin ecological into
For the vital task of the current water ecological environment comprehensive regulation.No.1 Central File in 2011 points out that " water is life
Source, production will, the base of ecology ", " improvement for accelerating middle and small river " work, " continue to promote ecological crisp
Weak river and regional Water Ecological Recovery, accelerate seriously polluted rivers and lakes water environment treatment ".
Subtropical monsoon climate high altitude localities weather makes a clear distinction between the four seasons, and cold and heat change is obvious, and day and night temperature is big.
Winter is cold dry, and summer sweltering heat is short of rain, freezeup period length.Typically for the Northern Hemisphere, subtropical zone monsoon gas
Regional freezeup period is waited as December, March next year terminates, during this period, although algae will not occur for river course
China's outburst, but intake and still carry the nutrition of algal bloom when a large amount of pollutants provide temperature rise
Material, therefore the polluter for reducing winter water inlet is important to control river eutrophication.This is objective
On require that processing system possesses winter purifying property.Further, since temperature reduces, microbial biochemical effect subtracts
It is weak, contaminant removal capacity is reduced, it is necessary to which the detergent power for the reinforcing freezeup period that takes measures is unaffected.
The content of the invention
In view of this, the present invention is provided at a kind of river channel ecology for subtropical monsoon climate high altitude localities
Reason system, it can be handled urban river water at all seasons, and makes the water quality of treated water
