Description
Technical field
The utility model belongs to field of water treatment technology application, is specifically related to a kind of intensified by ultrasonic wave air-floating apparatus that removes algae and algae toxin.
Background technology
Along with the quickening of social process of industrialization, the mankind enter pollutent nitrogenous in a large number, phosphorus in water body in industrial and agricultural production and daily life, quickened the eutrophication process of river, lake and reservoir.Body eutrophication has become the main illness of global water body, and algal bloom forms " wawter bloom ", consumes oxygen in water, distributes stench, destroys the eubiosis of water surrounding, and wawter bloom is the main environment disaster of body eutrophication.In the water body of eutrophication, in the production of tap water, high algae source water can stop up the filter tank; Also influence the coagulating sedimentation effect, its coagulation complex compound can penetrate the filter tank, influences delivery turbidity, causes the corrosion and the secondary pollution of pipe network.At present to the treatment process of algae comprise mainly that manual work is fished for, flocculation, chemical method, air supporting and chemical oxidization method etc.
The lake of China more than 70% receives algae pollution; China considerable part city all is to be main water source with reservoir, lake; Frond discharges a large amount of algae toxin humans and animals is produced very big toxic action, causes severe contamination for living water, influences water treatment procedure.Each big lake and reservoir of China detected in succession Microcystin (Microcystins, MC).People more and more is paid close attention to the harm of the Microcystin of wawter bloom release to environment and HUMAN HEALTH.Treatment process to the algae toxin mainly comprises filtration and absorption, chemical method, photochemical catalytic oxidation, membrane technique, biological degradation and ultrasonic technology etc.
Air supporting is used widely aspect algae removal, adopts air-float technology to handle high algae water, and its advantage is reached common understanding in field of water treatment, obtains promotion and application gradually at water supply plant.But discover that air-float technology has certain limitation to ultra's processing, when raw water turbidity surpassed 100 NTU, the water outlet effect worsened.Test shows, air flotation pool remove algae efficient up to 90%, but exist algae-residue to be difficult to shortcomings such as processing, stink weight, operating environment difference.Air-float technology can effectively be removed algae in the water, but can't remove dissolved algae toxin in the water.
Utilize UW that the degrade research of aspect of algae has also been obtained progress.Ultrasonic radiation can suppress the division of blue-green algae cell.Ultrasonic while ripple can make that pseudo-ghost breaks in the blue-green algae cell, and breaking of pseudo-ghost can make cell sink in the blue-green algae cell, so reduce frustule photosynthesis, strengthen the predation of zoobenthos, thereby reach the effect of control algae.Simultaneously, the UW algae toxin of can also degrading effectively, the ultrasonic generator of 640 kHz to MC-LR 3min after concentration reduce to original half the.But discover that the healthy of drinking person in serious threat if directly irradiation can cause frustule to break on the contrary and discharge certain algae toxin.
air supporting and ultrasonic technology can both be removed certain algae or algae toxin separately, but simple air floatation alga removing can't be removed dissolved algae toxin in the water, and simple UW removal algae can make frustule break and discharge the algae toxin.Therefore, await further raising, seek the method that is fit to remove simultaneously algae and algae toxin and seem particularly important for the removal efficient of algae and algae toxin.
Summary of the invention
The purpose of the utility model is to provide a kind of has the ability of removing more by force, efficiently remove the intensified by ultrasonic wave air-floating apparatus of algae and algae toxin.
The intensified by ultrasonic wave air-floating apparatus that removes algae and algae toxin that the utility model proposes; Connected to form through pipeline and valve by tank 1, coagulation reaction tank 7, electric air flotation pool 8 and ultrasonic response pond 15, tank 1 bottom one side is through valve 2, intake pump 3 and valve 4 and pipe connection coagulation reaction tank 7 tops; Coagulation reaction tank 7 tops are equipped with medicine machine 5, and whisking appliance 6 inserts in the coagulation reaction tank 7; In the electricity air flotation pool 8 battery lead plate 9 is installed; Electricity air flotation pool 8 tops are equipped with track type dreg scraper 10; Track type dreg scraper 10 1 sides link to each other with scum silica frost receiving tank 11; Mass-energy transmodulator 16 and ultrasonic generator 17 are housed in the ultrasonic response pond 15, and mass-energy transmodulator 16 connects ultrasonic generator 17, and whisking appliance 6, battery lead plate 9, track type dreg scraper 10, mass-energy transmodulator 16 and ultrasonic generator 17 are connected self-con-tained unit 14 respectively.
In the utility model, the quantity of said battery lead plate 9 is determined on a case-by-case basis, and the positive and negative electrode battery lead plate is alternately arranged.
In the utility model, 15 tops, said ultrasonic response pond, one side is provided with overflow weir 18, and overflow weir 18 belows are provided with rising pipe 19.
In the utility model, said electric air flotation pool 8 bottoms are provided with blow-down pipe 12, and said blow-down pipe 12 connects valve 13.
In the utility model, said self-con-tained unit 14 adopts rly..
The advantage of the utility model is: investigate removal effect from the aspects such as starting point concentration of ultrasonic frequency, power, ultrasonic time, coagulating agent kind, air supporting required voltage and algae (algae toxin); Overcome and remove the deficiency of algae and algae toxin technology now separately, thereby set up a kind of new process integration.Utilize air supporting to remove in the water it is thus clear that behind the algae, through remaining algae toxin in the cavitation effect of ultrasonic waves removal water, this method can effectively be removed algae and algae toxin simultaneously.
The utility model is dosing in coagulation reactor, stirs certain hour, makes frond form flco; Through the electric floating frond come-up that makes, the frond of come-up is removed under the effect of track type dreg scraper then, and frond forms flocs unit in the water; Do not destroy frond, have well and go turbid effect except that algae.UW is then removed a small amount of algae toxin that deliquescent algae toxin and electric floating technology discharge, and reaches rapidly and efficiently removal frond and the effect of algae toxin.
In the utility model, used ultrasonic time is 15 ~ 30min.
