Abstract
The invention belongs to the art of electrochemical oxidization. Disclosed is an electrolytic treatment system for shipboard ballast water, by electrolyzing the shipboard ballast water directly in the electrolytic treater, highly-effective oxidant which contains one or more among Cl2, HClO molecule, ClO2, free oxygen and hydroxyl radical, being generated, and by the force of electric field, the creature in shipboard ballast water being killed or deactivated. The online detective element measures the concentration of the generated oxidant and sends an electrical signal to an electrical power controller, which can adjust by said signal the electrolytic voltage or adjust treatment flow capacity by changing the opening of the valve when the ballast pump is a centrifugal pump, to keep the concentration of the oxidant in a right range. The invention can effectively remove microcosmic salt out of seawater, reduce the content of COD and TOD in seawater, and increase the dissolved oxygen in seawater. It improves the quality of seawater.
Description
Technical field
The invention belongs to the electrochemical oxidation technology field, relate to a kind of water electrolytic treatment system of ballast for cruising, is the application in the ballast for cruising water treatment field of electrochemical oxidation skill, electrolysis tech and electric field inactivation technology.
Background technology
The marine species that causes with ballast water for ship is to the infringement of marine environment, organized GlobalEnvironment Facility to be called for short four big one of threaten that GEF confirms as the harm ocean by Global Environment Facility.IMO has passed through " international shipping ballast water and sediment management and control pact " in February, 2004 for this reason.Have at least at present to be no less than 25 kinds of ship ballast water treatment method, but do not have a kind of mono-treatment technology can satisfy five standards that IMO proposes, promptly safe, practical, economic, effective and environment is allowed.
Summary of the invention

The mutation analysis that uses the present invention to handle the front and back seawer quality be the results are shown in Table one:
The report of table one seawater quality analytical test
| Analysis result: | |||
| Seawater is untreated | Handle seawater | ||
| Nitrate, Nitrite An orthophosphate salt COD DO salinity TOC suspension Zhuo degree electrical conductivity inorganic nitrogen | 616.9 28.2 72.8 10.2 0.52 8.22 29.432 4.01 8.2 11.9 33.89 717.9 | 379.0 3.1 24.6 4.3 0.36 9.54 29.509 3.50 7.8 11.0 34.48 406.7 | ug/L ug/L ug/L ug/L mg/L mg/L mg/L mg/L ms/cm ug/L |
As follows to last table analysis:
1. nitrate, nitrite and the ammonium salt in the table is the summation of inorganic nitrogen in the water, at China's Seawater Quality Standards (GB3097-1997)
[64]Middle inorganic nitrogen concentration should be controlled at 0.2mg/L (1 class water body), 0.3mg/L (2 class water body), 0.4mg/L (3 class water body), 0.5mg/L (4 class water body).Nitrate, nitrite and ammonium salt concentration before and after handle as can be seen, inorganic nitrogen has obtained removal to a certain degree, and is wherein best with the nitrite treatments effect.Because the 4th phosphate in inorganic nitrogen and the table all is the main matter that causes body eutrophication, be significant therefore to its removal.With reference to the 4th class water body (being applicable to the harborage area, ocean, the ocean exploitation operating area) of Seawater Quality Standards as can be seen, handle the requirement that back three's sum can satisfy 0.5mg/L.
" Pollution From Ships thing effluent standard "
[65]There is not concrete regulation among the GB3552-83.
2. treatment technology also has removal effect preferably to phosphate.Reactive phosphate concentration should be controlled at 15ug/L (1 class water body) in the Seawater Quality Standards, 30ug/L (2 class water body), 30ug/L (3 class water body), 45ug/L (4 class water body).The phosphate index all can satisfy the requirement of all kinds of water bodys before and after also promptly handling, and handles its concentration of back and is minimized.
3.COD reducing substances concentration in the expression water (mainly being pollutants), the reduction of its concentration means that certainly water quality is better.COD concentration should be controlled at 2mg/L (1 class water body) in the Seawater Quality Standards, 3mg/L (2 class water body), 4mg/L (3 class water body), 5mg/L (4 class water body).All pretty good before and after handling in the table.This value much higher (60-120mg/L) in the urban sewage discharge standard.
4.DO (dissolved oxygen) high more water quality that shows is good more, its value is relevant with temperature, salt content, bar pressure etc.(20 degree) this value of 9.54mg/L should be very high concerning general fresh water water body at normal temperatures.
5. salinity, conductivity, suspended matter and turbidity change all not obvious.Last is the inorganic nitrogen in article one just, is the former three sum.
6.TOC be the total organic carbon concentration in the water, the pollutants in the low more expression water is few more.
Annotate: the first kind is applicable to the marine fishery waters, marine natural reserve and rare marine life in imminent danger protected zone.Second class is applicable to the aquaculture district, the bathing beach, the movement overseas or the game preserve of human body direct contact seawater, and with the edible directly relevant industrial pool of the mankind.The 3rd class is applicable to the general industry Water District, the strand Scenic Spot Area.The 4th class is applicable to the harborage area, ocean, the ocean exploitation operating area.
Water sample to electrolytic treater electrolytic treatments 1 is analyzed.Table two to table six is the treatment efficiency testing result.

From above-mentioned test results, except that the algae of Cosinodisus can not be distinguished anyway, all the other detected plankton and all can be killed.
Till when this paper finalizes a text, about " to the approval guide rule of Ballast Management system "
[77]" ballast water treatment technological project approval guide rule "
[78]Resolutions does not pass through as yet, so the test and the evaluation of apparatus for treating ship ballast water are not still had unified standard.
It should be noted that in addition, bacterium is not cooked culture assays in above-mentioned test, because evidence repeatedly, the initial chlorine residue of 4.0mg/L is enough to whole killing bacterias.In order to determine whether the electrolytic treatments ballast water for ship can produce THMs, our experiment of knowing clearly.Monitoring method adopts headspace gas chromatography.Table seven shows experimental result.The haloform class (TTHMs) that chlorination is handled in the water sample of back is analyzed (headspace gas chromatography) report: the μ g/L of content unit.

Stipulate in many national water quality standard for drinking waters that TTHMs is less than 100 μ g/L (ppb).China's GB drinking water sanitary standard (GB5749-85) governing criterion is 60 μ g/L.
From table seven as seen, during the primary seawater of electrolytic treatments, be processing with 200mg/L, can produce the methenyl choloride amount much smaller than 60 μ g/L.
That is to say, the problem of being concerned about most with regard to people that can produce chloroform, from security standpoint and environmental angle, the electrolytic treatments ballast water for ship, environment can be accepted and allow.
