Embodiment
To the waste water processing demands of refuse leachate particularly, a kind of Waste Water Treatment is provided to now.In this system, the mode that adopts UW to combine with ozone is carried out physics and chemical treatment simultaneously, separates the objectionable constituent in the waste water fully, further carries out high-frequency pulse voltage simultaneously and handles the heavy metal composition in the filtering waste water.
Consult 1, the structural representation of one embodiment of the invention Waste Water Treatment.Waste Water Treatment comprises:
First treating pond 10 is equipped with UW and frees device and ozone flow in pipes 103 in first treating pond 10.
Through introduction pipe waste water is introduced first treating pond 10 through water leg generally speaking, waste water gets into after first treating pond 10, and ultrasonic generator 101 is started working, and UW is got in the water.Cavitation effect can take place after getting in the water in UW, and cavitation effect can make various composition mixed at high speed inner in the waste water, for the degraded of organic ammonia nitrogen composition with separate the environment that provides good, and UW itself also can decompose some impurity in the waste water.In waste water, inject ozone through ozone flow in pipes 103 simultaneously, ozone has strong oxidation, can decompose the ammonia and nitrogen components in the waste water, owing to simultaneously action of ultrasonic waves is arranged, it is thorough more and abundant to make that the oxygenizement of ozone in waste water carried out.Through the dual function of UW and ozone, organic compositions such as the ammonia nitrogen in the waste water are fully decomposed, and have reached the purpose that promotes water quality.Waste water through first treating pond 10 is handled gets into second treating pond 20.
Second treating pond 20, the waste water through after 10 processing of said first treating pond is equipped with the high-frequency pulse voltage producer in second treating pond 20.
After waste water gets into second treating pond 20, open high-frequency pulse voltage producer 201, waste water is applied high-frequency pulse voltage.Under the effect of high-frequency pulse voltage, the heavy metal contaminants in the waste water is removed.
The 3rd treating pond 30; Waste water after reception is handled through second treating pond 20; Waste water utilizes MRB treatment system 301 to carry out MRB in the 3rd treating pond 30 and handles and carry out precipitation and separate; The 3rd treating pond 30 dresses also are equipped with pH value setter (figure does not show), in the 3rd treating pond 30, add the pH value regulator solution to regulate the acid-basicity of waste water, further increase water quality.
From can think the processing of accomplishing waste water through the waste water of the 3rd treating pond 30 processing, discharge.
Further, as a new more concrete embodiment, each above-mentioned treating pond and collecting tank 40 all are independent, accomplish the transfer of waste water in each pond through feeding apparatus are set, and switch-valve 80 grades also can be set keep UNICOM and partition between the pond.Guarantee that waste water does not reflux.
Further, before waste water gets into collecting tank 40 or in collecting tank 40, waste water being carried out tubular fibre 3012MBR handles.Also can carry out other further purifying treatment.
In first treating pond 10, realize that with the pipeline of a threeway ozone injects and waste water is discharged.The ozone that ozonizer 105 produces gets into pipeline; Extract waste water out from first treating pond, 10 bottoms, get into ozone flow in pipes 103, with the ozone flow in pipes 103 of ozonizer 105 generations; Water and ozone mix; Make the gas-liquid thorough mixing through gas-liquid mixing pump, inject the waste water of first treating pond 10 then through ozone flow in pipes 103, can pipeline be extended to the bottom of first treating pond 10.Ozone flow in pipes 103 can with the wastewater discharge pipe road UNICOM of first treating pond 10, receive the wastewater discharge pipe of first treating pond 10 in ozone flow in pipes 103 parts of first treating pond 10 through three ports, drain into second treating pond 20.
On the next door of first treating pond 10 supervisory control desk 107 can be set, be used to control ozonizer 105 and UW voltage generator.In second treating pond 20, the discharge electrode 2012 of high-frequency pulse voltage producer 201 can carry out modularization to be handled.For example will handle the discharge electrode 2012 of a waste water ability and make a module.Each module is independent, to realize carrying out combined modules flexibly to treatment capacity.The control section of radio-frequency generator can hang over outside the pond of second treating pond, also can place supervisory control desk 107.Consult Fig. 2, the vertical view of 2012 modules of discharge electrode is a fixed module among the figure.
In the 3rd treating pond 30, the MBR treatment system is set.A plurality of back-shaped water pipes 3014 are set in the pond, on the water pipe of a reversion, connect tubular fibre 3012 between the part on both sides, waste water penetrates into tubular fibre 3012, enters into back-shaped water pipe 3014 through tubular fibre 3012.Top at each back-shaped water pipe 3014 is provided with opening, connects header, each header be pooled at a place the 3rd treating pond 30 water shoot, to get rid of waste water.Can extract waste water to header through water pump.
Also be provided with gas-adding pipe at second treating pond 20 and the 3rd treating pond 30, in waste water, inject air, make waste water in the pond, can fully stir.
Further consult Fig. 3, can also increase collecting tank 40, said the 3rd treating pond 30 UNICOMs, the waste water that receives after handling through said the 3rd treating pond 30 is collected; And
The 4th treating pond (figure does not show), said the 4th treating pond and collecting tank 40 UNICOMs receive through the water in the collecting tank 40, and the 4th treating pond carries out discharging Waste Water Treatment after reverse osmosis (RO) is handled to water wherein.
Further, in the build process of specific Waste Water Treatment, ozone can adopt the finished product ozone of buying, further can in this treatment system, install ozonizer 105 simultaneously, and the ozone that ozonizer 105 produces injects ozone flow in pipes 103.
In order to realize better effect, consult Fig. 4, on first treating pond 10, can set up the gas sampling lid; Because in the treating processes of 10 pairs of waste water of first treating pond; Ammonia and nitrogen components has carried out sufficient decomposition, can produce gases such as nitrogen, ammonia; And also can producing other under the ultrasonic effect that involves ozone, from waste water, separate other impurity; If these gases directly enter in the atmosphere, then can produce pollute air, increasing the discarded lid of collecting can collect and process from waste water, isolating the get up escape pipe 112 that covers setting through gas sampling of collection and confinement of gases.
Further, the present invention implements to give the method for wastewater treatment, handles the method for waste water during promptly said system is used.
Consult Fig. 5, the embodiment of the invention is handled the method flow diagram of waste water.
S100 carries out ultrasonic irradiation to waste water, injects the ammonia and nitrogen components that ozone has been removed waste water to said waste water simultaneously;
S102 continues to apply high-frequency pulse voltage in order to remove the heavy metal element in the waste water to waste water;
S103 adds pH value regulator, the acid-basicity of waste water at ordinary times in waste water;
S104 through the waste water of above-mentioned processing, imports treating pond and utilizes MRB treatment system 301 to carry out MRB to handle and carry out precipitation and separate, carry out reverse osmosis (RO) then and handle, collect the back at last and discharge.
The Waste Water Treatment of the embodiment of the invention and method; Need not increase chemicaladditives, effect makes waste water by fully oxidation in the time of through UW and ozone, and the effect of UW and ozone is not high to the space requirement of treating pond; Therefore can be according to treatment capacity suitable size that treatment system is set and floor space; Also obtaining easily and effect of high-frequency pulse voltage, so total system and method are simply effective, are easy to the processing to waste water.
