Description
Technical field
The utility model relates to a kind of eutrophic lake refining plant.
Background technology
Lake, while provide varied natural resources for the mankind, also suffer from the various pollutions caused by mankind's activity, eutrophication be exactly wherein the most obviously, the most serious one, it is also the omen of lake disappearance.For protection lake resource, eliminate eutrophication, China conducts a research and the manpower and financial resources of administering drops into countless, and the time length reaches decades.But so far, original eutrophic lake (as Taihu Lake, Dian Chi, Chaohu) is not still felt any better, and the lake of new eutrophication is continuing to bring out.
Found by research in recent years, eutrophication control is before the same just as harnessing the river before great Yu on Chinese history, where stifledly where bursts, and result has been determined stifled, blocked up and determined, in successive years; great Yu takes to dredge, and has from then on stopped flood.The current eutrophication control of China is very similar to " blocking up " (restriction sewage enters, and remove silt from the bottom of lake, dispenser algae removal, diversion is rushed rare), and ignores " dredging ".The utility model, according to the self-cleaning principle in lake, designs the improvement novel method that one is front topic with " dredging ".
Summary of the invention
The purpose of this utility model is to solve a kind of eutrophic lake refining plant that lake water eutrophication provides and utilizing its method purified Lake Water.
Know-why of the present utility model
Lake eutrophication mainly in lake water N (mainly with NH
4 +form exist), alga eruption caused by P excessive concentration, a kind of phenomenon of water degradation.In fact lake eutrophication causes the process of alga eruption, is also that the process that lake elimination N pollutes also is self-purification process: algal grown needs to absorb nutrition (N, P), needs the CO in the empty G&W of a large amount of absorption
2carry out photosynthesis, this uprises with regard to making the pH value of water, under alkaline environment condition, and the NH in water
4 +change NH into
3distribute to air, the N content in water is reduced, achieves the function of lake self-cleaning.
NH
4 ++OH
-＝NH
3↑+H
2O
But this natural process is fainter and slowly, wants to realize effect that is effective or that get instant result, artificial method will be taked to amplify this process: Xiang Shuizhong throws in alkaline matter, makes water become alkalescence, by NH
4 +change NH into
3, and constantly stir, make NH
3volatilized, for preventing the NH volatilized
3cause secondary pollution, absorb it and reclaim, regenerant can be used to the starting material making other products.
The technical solution of the utility model
A lake cleaning device for eutrophication, comprises alkali lye pond, NH
3absorb liquid pool, gas skirt, air pump, stirring system;
Described stirring system comprises stir shaft, agitating vane and agitator motor; Described stir shaft is through the top in the middle part of gas skirt, and the stir shaft on gas skirt top is connected with agitator motor, and agitating vane is arranged on the stir shaft of gas skirt bottom;
Described alkali lye pond bottom sides is provided with alkaline stream outlet, the outlet of this alkaline stream is passed downwards from gas skirt top after alkali lye bleed valve by pipeline, it passes when length will ensure that this pipeline uses and can directly insert in Lake Water, for adding alkali lye in Lake Water;
On gas skirt, press close to stir shaft place and be also provided with a NH near gas skirt
3collection tube, this NH
3collection tube is from bottom to top through gas skirt and by air pump and NH
3the gas distributor that top in absorption liquid pool is provided with is connected, and this gas distributor is positioned at NH
3absorb middle and upper part 2/3 place in liquid pool, during use, it is immersed in NH
3in absorption liquid.
Utilize the method that the lake cleaning device of above-mentioned a kind of eutrophication purifies Lake Water, concrete steps are as follows:
When the lake cleaning device of above-mentioned eutrophication uses, installed aboard ship, gas skirt is close to lake surface.
In the annual 5-9 month, fine day calm day selects the lake region that eutrophication is serious, and at 8 a.m., to enforcement at 17 in afternoon, (now temperature is higher, and aquatic plant absorbs CO
2strongly, lake water pH is high, is conducive to NH
4 +be converted into NH
3): the alkali lye bleed valve opening the outlet of alkali lye pond by mass percent concentration be 10% lime aqueous solution to control discharge rate be that the speed of 1.5L/min is added in lake water, and to control rotating speed be that 100r/min stirs, open the NH that air pump will produce in lake water simultaneously
3through NH after being collected by gas skirt
3the NH that collection tube will be collected
3send into NH
3absorb the NH of liquid pool
3in absorption liquid; After each operating point continues about 5min, shift to other places and continue to implement;
Described NH
3the hydrochloric acid of absorption liquid to be concentration of volume percent be 1-5%, sulfuric acid or aqueous nitric acid, when because absorbing NH
3make NH
3the pH value of absorption liquid higher than 6.5 time, the NH again more renewed
3absorption liquid, the pH value displaced higher than 6.5 NH
3absorption liquid storage is standby is used as him;
First close alkali lye bleed valve when stopping operation, then stop air pump and stirrer.
The beneficial effects of the utility model
Compared with current eutrophic lake Treatment process (dig clearly silt from the bottom of lake, diversion rush rare, dispenser and kill algae), the lake cleaning device of a kind of eutrophication of the present utility model is utilized to carry out purifying treatment to the eutrophication of Lake Water, lake natural ecosystems can not be upset, there is no secondary pollution, cost is low, easy enforcement, and NH
3recovery also can create new value.
