Description
Technical field
The invention belongs to environmental project technical field of sewage.Sewage treatment plant tail water is removed the invention discloses one kind
The method of middle estradiol, specifically, discloses one kind using Fe (III) and the reciprocation of microorganism, strengthened artificial wet land
The method for removing estradiol in sewage treatment plant tail water.
Background technology
The estradiol that estradiol is 10 ng/L in typical endogenous Estrogen, water environment is to show stronger life
State（Physiology）Toxicity, causes male sterility, tumors of female reproductive organ, children precocious, the decline of wild animal fertility, and
Aquatile feminizes.At present, many countries in Europe have formulated standard, limit its concentration of emission and must not exceed 10 ng/L.
Estradiol in environment is mainly derived from the excreta of the mankind and mammal.Estradiol is entered by number of ways
Enter municipal sewage plant.At present, the traditional handicraft of municipal sewage plant, particularly Anaerobic treatment technique can not be effective
Remove the estradiol in sewage.Generally, the level that the concentration of estradiol is ng/L- μ g/L in sewage plant tail water, so that, in tail water
Still retain higher estrogen active.
Advanced treating is carried out to sewage treatment plant tail water, and it is current sewage disposal to be back to ecological, landscape moisturizing
The main outlet of plant tail water.The method of common advanced treatment of wastewater mainly has deep-bed filtration method, ozone-active carbon method, chemistry
Coagulation Method, artificial swamp method etc..Wherein, artificial wetland process have that simple to operate, power consumption is few, operating cost is low, processing
The advantages of effect is good and be widely adopted.
Artificial swamp is a synthesis ecosystem.In system, microorganism is the main force of degradation of contaminant, and filler is micro-
Biology provides preferably attachment carrier, and wetland plant absorbs the nutrients such as Water, phosphorus, while being wet land system conveying
Oxygen, so that system is run in the alternate environment of anaerobic-aerobic.Estradiol is typical phytosterin compound, in wetland
In the anaerobism and anaerobic environment of system, because the electron transfer efficiency of anaerobe is low, estradiol is generally converted to oestrone,
Accumulated in wet land system, so that, higher estrogen active is still retained in the water outlet of artificial wet land system.Therefore, people is improved
The electron transfer efficiency of microorganism in work wet land system, the ability of lifting wet land system degraded estradiol, will substantially reduce sewage
The Ecological Environment Risk for the treatment of plant's vacuum in draft tube.
The content of the invention
It is strong using Fe (III) the invention provides one kind for the problem of estradiol clearance is low in artificial wet land system
Change the method that artificial swamp removes estradiol in sewage treatment plant tail water.
The purpose of the present invention is achieved by the following technical solution：
One kind removes the method for estradiol in sewage treatment plant tail water, specific steps using Fe (III) strengthened artificial wet land
It is as follows：
(1)：Build subsurface flow constructed wetland system, the wet land system length-width ratio 1:1-:4:1, depth 0.7-1.2 m；
(2)：Packed height is 0.5-1.0 m mixed fillers in the wet land system, and is mixed into mixed fillers quality
0.1% ~ 1% Fe (III), to improve the electron transmission efficiency of anaerobe in wet land system；
(3)：5-25 plants/m is pressed in wet land system2Density plantation reed；
(4)：It is that 0.5-1d injects sewage treatment plant tail water into wet land system by hydraulic detention time, debugs artificial swamp
System；
(5)：After wet land system is stable, estradiol is added to sewage treatment plant tail water, the concentration of estradiol is adjusted
For 20-2000 ng/L, artificial swamp is run by hydraulic detention time 0.5-2d.
In the present invention, wet land system length-width ratio described in step (1) is 1:1-:3:1, depth is 0.8-1.0 m.
In the present invention, mixed fillers are made up of zeolite and haydite described in step (2), zeolite：The volume ratio of haydite is 1:
1。
In the present invention, Fe (III) described in step (2) is goethite or bloodstone, goethite or the bloodstone addition
Measure as the 0.5% ~ 1% of mixed fillers quality.
In the present invention, the concentration that estradiol is controlled in step (5) is 20-200 ng/L.
The present invention has the advantage that compared with prior art：
The invention provides the side that a kind of brand-new strengthened artificial wet land removes estradiol ability in sewage treatment plant tail water
Method, specifically, exactly adds appropriate Fe (III) in artificial wet land system（Goethite or bloodstone）, structure Fe (III)-
Microorganism interactive system, lifts the electron transmission efficiency of microorganism, and strengthened artificial wet land is removed female two in sewage treatment plant tail water
The ability of alcohol.Compared with being not added with Fe (III) wet land system, this method can lift 50% to the removal ability of estradiol, so that
Greatly reduce the environmental ecology risk of sewage treatment plant tail water reuse.
