Description
Technical field
The present invention relates to a kind of wet land system being applied to cold district samll cities and towns.
Background technology
Numerous samll cities and towns of China all lack necessary sewage disposal system, due to samll cities and towns and rural infrastructure at present
Relatively backward, much there is drainage pipeline construction and do not build entirely in place, is directly arranged by the sewage that domestic animal, aquaculture and pesticide are formed
Enter water bodies of rivers and lakes, it has also become important polluter.And there is water quality and quantity change fluctuation greatly in Small Town Wastewater one side, pollutant
The features such as concentration is relatively low；On the other hand require processing system investment operating cost low, run and control simply, hence with existing big
Type sewage treatment plant maturation process (requiring water quality and quantity stable, investment operating cost is high, to control complicated) cannot solve samll cities and towns
Sewage handling problem.Cold district small-town sewage treatment system also requires freezeup period in the winter time can normally run, and ensures
Effluent quality is up to standard.
Artificial wet land system in existing sewage treatment process is the best technique choosing solving Small Town Wastewater process problem
One of select, but the whole year operation of cold district artificial swamp is then a problem urgently to be resolved hurrily.
(1) existing artificial swamp all cannot run in especially freezeup period in cold district winter, even if taking certain guarantor
Warm measure also cannot whole year operation.Mainly warming measure is provided using booth in existing cold district artificial swamp engineering,
But in the middle of actual motion, this warming measure can only extend run time 1-2 month.It is not added with the cold district people of warming measure
The annual run time of work wetland was at 6-8 month, and took the artificial swamp run time of warming measure to be then 8-10 month, still no
Method whole year operation.At annual the coldest 2 months about, warming measure still cannot make artificial swamp not ice-bound, if taking
The measure such as heating or increase heat-insulation layer, then investing operating cost will greatly improve.
(2) the low-temperature reinforcement measure of existing artificial swamp had both increased operating cost, so that operational management is complicated again.It is unfavorable for
Promote in samll cities and towns.
(3), during cold operation, due to the reduction of oxygen in water, treatment effect is undesirable, very for existing artificial swamp
The root system of plant staying hypothalluses is made to occur rotten to too low dissolved oxygen, sewage fouls, further polluted water.
Content of the invention
The present invention is to solve existing cold district samll cities and towns artificial swamp cannot whole year operation, and low-temperature reinforcement measure
Both increased operating cost, make again operational management complicate, existing artificial swamp during cold operation, due to oxygen in water
Reduce, the undesirable technical problem for the treatment of effect, thus providing a kind of latent interlayer of solar energy being applied to cold district samll cities and towns
Have a rest aeration artificial wet land system.
A kind of solar energy being applied to cold district samll cities and towns of the present invention dives layer intermittent aerating artificial wet land system by square
