Description
[technical field]
The present invention relates to environmental protection, city has stable political situation hydro project technical field, specifically, is a kind of being applicable in water remediation the new medium unitized design of water body bank inlet for stom water and sewage draining exit buffer belt and constructional method.
[background technology]
For a long time, functions such as " flood control, water drainage, shipping, irrigation, cultivation " that the understanding of people to water surrounding effect is only confined to, ignore the eco-environmental conditions function of water surrounding, cause current China major part water ecosystem seriously impaired, body eutrophication and water quality deterioration phenomenon general.Wherein water body external source pollutes input is one of principal element causing these environmental phenomenon for this, and various drainage pipeline is a large amount of pollutent to discharge into water.Perfect along with civilian infrastructure, sewage network is popularized gradually, but the rainwash that rainwater produces directly enters the Main Morphology that river remains certainly most of urban rainwater whereabouts, and this point is more obvious in south.According to domestic and international enquiry data, in developed country, rainwash enter that river can account for that nutrition input in river meets more than 50%, therefore, be know clearly to weaken the impact of external source import, should manage to cut down the impact of external source import on water quality as possible.
Although the method controlling rainwash has a lot, comprise and strengthen earth's surface water-permeable to reduce Surface Runoff, retain early-stage rainwater and enter municipal wastewater treatment plant and sanitary sewage merging treatment (half streaming run-off system) carries out processing to cut down the technology such as most of pollutants discharged into rivers, but the input of rainwash to natural water is difficult to fundamentally stopping completely, local in the overwhelming majority in other words, when current environmental protection, municipal input funds are limited, be difficult to eliminate the phenomenon that a large amount of rainwater directly enters natural water.In addition some big cities are adopt again to build Storm Sewer Network in the method for Xincheng District, and the rainwater/early-stage rainwater collected is transported to specific rainwater treatment plant stand by pumping plant, discharge water inlet body after precipitation or coagulating treatment (coagulation).But this mode is referred from fact the thinking of conventional sewage collection and treatment, except going up north except wide small part city, be still difficult in the domestic cities and towns of the overwhelming majority promote.In this more external among a small circle, small-scale aquatic ecological restoration Practical Project, often meet low discharge (such as < 5m
3/ d) sewage draining exit, these little sewage draining exits are often difficult to cut dirty and resettlement by pipe network in a short time and solve, and the rainwater discharge outlet of low discharge is then more common.The external source produced these low discharge rainwater discharge outlet, sewage draining exit is polluted and is not added process, often produces larger baneful influence to water remediation effect again, takes newly-built pipe network to cut and dirty etc. control root means and often invest and be difficult to bear.
Therefore the rainwater or the discharge of low discharge sewage draining exit that adopt low cost low technical technique to manage entering natural water are suitably tackled and process certain practical significance, in real work, often the most common is adopt waterplant to build buffer strip, and such as the most common is form plant absorption band after adopting watermifoil to plant near discharge outlet.But this mode is often difficult to form good interception result, and main drawback is as follows: (1), because the irregularity of plant-growth causes space very large, interception property is poor; (2) and plant-growth have a longer process, onset required time is long; (3) plant has the season of growth, and for perennial watermifoil, namely autumn and winter season generally withers and survive the winter, and among 1 year, the long duration does not have interception function like this.
Therefore the in line reply for rainfall runoff and little, micro-disposal of pollutants source always is the problem perplexing aquatic ecological restoration engineering.Searching construction is fast, instant effect, cost are low, disturb little counter-measure very urgent and important.
[summary of the invention]
The object of the invention is to overcome the deficiencies in the prior art, a kind of the new medium unitized design and the constructional method that are applicable to inlet for stom water and sewage draining exit buffer belt in water remediation are provided.
