Description
Technical field
The invention belongs to field of waste water treatment, and in particular, to a kind of pumping plant that removes simultaneously gives up Organic substance in water and phosphorus
Method, this method are suitable for rainfall pumping station, confluence sewage pumping station and River shove regulation and put the field of waste water treatment before river (river).
Background technique
In recent years, the whole nation has nearly 50% middle and small river to receive serious pollution, wherein 41% is bad V class water quality.According to
Chinese environmental bulletin investigates the pollution announced after 131 urban rivers the results show that the river water of main stream of the Yangtze about 40% is more than III
The river water of class water quality standard, Huaihe River section even 78% cannot function as drinking water.It is close especially with industrial development and urban population
The increase of degree, the organic contamination in river, eutrophication, black smelly problem are more universal.
When organic contamination is higher, the dissolved oxygen in water body is largely consumed, and so that water body is in severe depletion of oxygen state, is caused
The anaerobic digestion of anaerobe generates river water black smelly.The a large amount of of phosphorus-containing detergent make in sanitary sewage
Phosphorus content dramatically increases, and the discharge of Phosphorus From Wastewater easily causes water eutrophication, it was reported that the phosphorus of 0.02mg/L will cause algae
Class is broken out, and algal bloom will lead to fish mortality, brings serious impact to ecological environment.Water eutrophication is also given
Human lives bring tremendous influence, as the tap water crisis thing caused by the Taihu Lake cyanobacterial bloom of Wuxi occurs in May, 2007
Part has further highlighted the severe situation of China's rivers and lakes eutrophication.
Interflow formula pumping plant waste water is made of rainwater and municipal sanitary sewage, contains a certain amount of organic pollutant and phosphorus；Cause
Serious for China's most cities rain dirt hybrid junction, causing shunt rainfall pumping station also has a certain amount of sanitary sewage.Due to pumping plant
Direct discharging of waste water enters rivers, is currently one of the main reason for causing river pollution.It is therefore necessary to control its organic matter and
The concentration of phosphorus is to reduce the organic contamination and eutrophication crisis in natural water.Especially period in dry season pumping plant often has accumulated
More sewage, once more serious pollution can be brought to river by putting river.And national most cities are for pumping plant waste water at present
Treatment measures are not taken before putting river.
The present invention relates to a kind of methods for removing pumping plant useless Organic substance in water and phosphorus simultaneously, and this method technological operation is simple,
Removal efficiency is high, and medicament has environment friendly, will not have a negative impact to natural waters such as rivers, has wide answer
Use prospect.
Summary of the invention
The purpose of the present invention is a kind of open methods for removing pumping plant useless Organic substance in water and phosphorus simultaneously, and this method can be quick
The organic matter and phosphorus in pumping plant waste water are removed, process is simple, is suitable for rainfall pumping station, confluence sewage pumping station and River shove regulation
Wastewater treatment before putting river (river).
The purpose of the present invention can be achieved through the following technical solutions.
Method that is a kind of while removing pumping plant useless Organic substance in water and phosphorus, method includes the following steps:
(1) it is calculated according to the volume of processing waste water and weighs a certain amount of anhydrous ferric chloride and calper calcium peroxide solid；Wherein,
Preferably, the concentration of anhydrous ferric chloride be 20~100mg/L, it is highly preferred that the concentration of anhydrous ferric chloride be 32.5,50 or
100mg/L, it is preferable that molar ratio 1:0.5~1:2 of anhydrous ferric chloride and calper calcium peroxide, it is highly preferred that anhydrous ferric chloride and mistake
The molar ratio of calcium oxide is 1:1 or 1:0.5；
(2) it is added at one time the weighed anhydrous ferric chloride of step (1) into pumping plant collecting-tank waste water and calper calcium peroxide is solid
Body, turn on pump, which quickly stirs 3~10min, to be dissolved in anhydrous ferric chloride and calper calcium peroxide solid in waste water and uniformly mixes；Preferably,
Turn on pump quickly stirs 3mim, 5mim or 8min；
(3) after reaction, close pump, make the quiet heavy 10~60min of waste water, it is preferable that make the quiet heavy 10min of waste water or
Supernatant liquor is discharged later by 15mim, it is preferable that supernatant liquor is discharged into river (river).
Preferably, the pumping plant is rainfall pumping station or confluence sewage pumping station.
Preferably, the method also removes the emerging pollutants such as carbamazepine simultaneously.
The present invention have following remarkable advantage and the utility model has the advantages that
(1) of the invention open one's minds is to utilize oxygen associated with the coagulation of anhydrous ferric chloride and calper calcium peroxide and iron simultaneously
The property changed, can effectively remove organic matter and phosphorus in a short time.Trace drug difficult to degrade can also be removed such as using the present invention
The emerging pollutants such as carbamazepine, therefore the present invention has broad application prospects.
(2) amazing, through the results show, the present invention can remove simultaneously organic matter in pumping plant waste water and
Phosphorus, and removal efficiency is high, phosphorus concentration of the organic removal rate after 60% or more, reaction is lower than detection limit (close to zero).
(3) it in addition, operation of the present invention is simple, is swift in response, without in addition building pond or changing to pumping plant collecting-tank
It makes.
