Description
Technical field
The present invention relates to a kind of system and method that is used to administer city inland river pollution.
Background technology
All there is one or several city inland river in each city at first stage of construction, and its major function is flood discharge in rainy season and urban sewage river.But along with the raising of urbanization degree, people are to the raising of environmental quality requirement, and the function of water body of city inland river is changed into view and flood discharge river by blowdown flood discharge river.But because just the water quality of rain is relatively poor in the city, the rainwater behind the surface runoff near or surpass the water pollution degree of municipal wastewater treatment plant.And resident along the river topples over domestic refuse to Ha Noi, and effluent is stolen to the inland river by enterprise.Therefore, city inland river pollution is serious.National governments all at the improvement city inland river of actively making great efforts, guarantee under the prerequisite of its water body flood discharge function, purify beautifying water body, make it to become the city beautiful scenery, rather than the sewage ditch that lets the people step back.But present existing resolution running cost is generally higher.
Summary of the invention
The objective of the invention is to reduce the running cost in the governance process of inland river, a kind of unpowered city inland river pollution governing system is provided.
Unpowered city inland river pollution governing system; It is characterized in that it comprises anaerobic biofilter formula city inland river dykes and dams treatment system and aerobic ecological riverway treatment system two portions; Said anaerobic biofilter formula city inland river dykes and dams treatment system is built along the river; Said aerobic ecological riverway treatment system is made up of aerobic ecological cobble riverbed and balanced wicket system; Said aerobic ecological cobble riverbed is arranged on river course bottom, and said balanced wicket system is arranged on downstream, river and the interception of width along the river river.
Unpowered city inland river pollution improvement method, it comprises that successively anaerobism is administered the dykes and dams process section and aerobic cobble ecological riverway water quality is administered two stages of section;
The process that said anaerobism is administered the dykes and dams process section is:
Sewage such as rainwater flow into from the source drainage inlet of anaerobic biofilter formula city inland river dykes and dams treatment system; In the process of the anaerobe filter dam body of the anaerobic biofilter formula of flowing through city inland river dykes and dams treatment system, utilize the anaerobe film on the rubble surface in the anaerobe filter dam body to handle the sewage that flows into the rubble gap; Sewage flows into the reservoir chamber in the anaerobic biofilter formula city inland river dykes and dams treatment system from anaerobe filter dam body, when water level reaches the height into the river course water port, flow out to aerobic ecological riverway treatment system from going into the river course water port;
The process that said aerobic cobble ecological riverway water quality is administered section is: sewage is discharged in the aerobic ecological riverway treatment system from going into the river course water port; The sewage following current gesture diffluence downstream of discharging; When river is flowed through aerobic ecological cobble riverbed during this time, utilize the aerobic biologic membrane on the cobble surface in aerobic ecological cobble riverbed that river is carried out the biochemical purification effect, when river flow to the balanced wicket system that is positioned at this inland river downstream end, tackled; When the river water level reaches the waterpower elevation that the balanced wicket system opens; The balanced wicket system relies on hydraulic pressure to open automatically, forms drop water aeration, and river flows out to downstream river course from the balanced wicket upper edge of balanced wicket system.
Positively effect of the present invention:
Unpowered city inland river pollution governing system of the present invention makes sewage filter dykes and dams, aerobic ecological cobble riverbed biochemical treatment through anaerobe, and hockets repeatedly and reach the purpose of purification of water quality.Filter the apparent state that improves water quality through anaerobe, purify water, make the water quality view performance that gets in the city inland river good, further make water quality reach the view water quality standard through the ecological river bed aerobic Ecological Disposal of cobble in the river course.The dissolved oxygen mode of the aerobic Ecological Disposal of water quality comprises nature dissolved oxygen and drop water aeration dissolved oxygen dual mode in the riverbed; Wherein the drop water aeration dissolved oxygen adopts the design of panel turnover sluice gate gate-type, and when the river water level reached the waterpower elevation of balanced wicket unlatching, balanced wicket relied on hydraulic pressure to open automatically; Need not driven by power; This moment, big waterpower drop formed drop water aeration, utilized natural drop water aeration and then realized the unpowered oxygenation to river, can save running cost.
