Abstract
The present invention discloses a kind of administering method of black and odorous river, in turn includes the following steps：After the black smelly soil of black and odorous river is dug out, the ratio that 0.1~0.25 kilogram of quick lime is added according to the black smelly soil of per kilogram mixes, installed after mixing with woven bag, after placing 7~10 days, lime hardens, the black smelly soil that woven bag is installed is transported to the one end in river, build a short dam, the black smelly soil installed under short dam with woven bag is filled out in river bottom, and form gradient slope, one water pump is set in short dam, the other end of the intake of water pump in river, it will enter and be pumped into short dam, overflow and go out, water is allowed to be flowed on gradient slope, eventually arrive at the other end in river, circulation is repeatedly, pass through oxygenation, obtaining Water quality improves.It is an advantage of the invention that forming gradient slope using the smelly soil of quick lime fixed black, and using it, solves the black intractable problem of smelly soil, and oxygenation, reach the purpose for improving water quality of river into down stream system using gradient domatic.
Description
Technical field
The present invention relates to water body treating field, more particularly to a kind of administering method of black and odorous river.
Background technology
City black and odorous water is the water environmental problems that the common people have strong complaints, and not only compromises human settlement environment in city, also seriously
Influence city image.
In the prior art, generally the black and odorous water is administered by two methods, one kind is aeration, aeration
It is by being passed through air or oxygen into the black and odorous water, to improve the oxygen content in water body, using this method to black smelly water
Need to be passed through substantial amounts of oxygen-containing gas when body is administered, it is in large scale, meanwhile, the water body can not be reduced using this method
In concentration of nitrogen and phosphorus, it is thus impossible to fundamentally solve water body black smelly problem；Another kind is planting plants method, passes through the party
Method can absorb to the nitrogen phosphorus in the black and odorous water, and still, herbaceous plant carries out oxygen caused by photosynthesis in this method
Gas is discharged into air through blade, it is difficult to is solved the problems, such as that dissolved oxygen amount is low in black and odorous water, therefore, regulation effect unobvious, is controlled
It is low to manage efficiency.
The content of the invention
A kind of administering method of black and odorous river is provided the invention aims to solve above-mentioned deficiency.
The technical solution adopted by the present invention is in turn include the following steps：
After the black smelly soil of black and odorous river is dug out, 0.1~0.25 kilogram of quick lime is added according to the black smelly soil of per kilogram
Ratio mixing, installed after mixing with woven bag, after placing 7~10 days, lime hardening, the black smelly soil that woven bag is installed is transported
To the one end in river, a short dam is built, the black smelly soil installed under short dam with woven bag is filled out in river bottom, and forms gradient slope,
One water pump is set in short dam, the intake of water pump is pumped into entering in short dam in the other end in river, overflow and go out, allow water
Flowed on gradient slope, eventually arrive at the other end in river, repeatedly, by oxygenation, obtaining Water quality improves for circulation.
It is an advantage of the invention that forming gradient slope using the smelly soil of quick lime fixed black, and using it, solves black smelly mud
The intractable problem of soil, and oxygenation, reach the purpose for improving water quality of river into down stream system using gradient domatic.
Brief description of the drawings
Fig. 1 is a kind of administering method schematic diagram of black and odorous river
Embodiment
Embodiment 1
It is shown in Figure 1, after the black smelly soil of black and odorous river is dug out, 0.25 kilogram is added according to the black smelly soil of per kilogram
The ratio mixing of quick lime, is installed after mixing with woven bag, after placing 10 days, lime hardening, and the black smelly mud that woven bag is installed
Soil is transported to one end to be harnessed a river, and builds a short dam 1, and the black smelly soil installed under short dam 1 with woven bag is filled out in river bottom, and
Gradient slope 2 is formed, a water pump 3 is set in short dam 1, the intake 4 of water pump 3 will enter and be pumped into short dam 1 in the other end in river
It is interior, overflow and go out, allow water to be flowed on gradient slope 2, eventually arrive at the other end in river, circulation repeatedly, passes through oxygenation, obtains water
Weight improves, and oxygen content maintains 10~11mg/L.
Embodiment 2
After the black smelly soil of black and odorous river is dug out, the ratio for adding 0.1 kilogram of quick lime according to the black smelly soil of per kilogram is mixed
Close, installed after mixing with woven bag, after placing 7 days, lime hardening, the black smelly soil that woven bag is installed, which is transported to, to be waited to harness a river
One end, build a short dam 1, the black smelly soil installed under short dam 1 with woven bag is filled out in river bottom, and forms gradient slope 2, short
One water pump 3 is set in dam 1, the intake 4 of water pump 3 will enter and be pumped into short dam 1 in the other end in river, overflow and go out, allow water
Flowed on gradient slope 2, eventually arrive at the other end in river, repeatedly, by oxygenation, obtaining Water quality improves, oxygen-containing for circulation
Amount maintains 10~11mg/L.
Claims (1)
