Description
Technical field
The invention belongs to nanotechnology and biology techniques Application Areas, particularly a kind of nanostructure millipore filtration and uv-radiation combine and administer the device of ballast water for ship biotic intrusion.
Background technology
Ballast water for ship is the main approach that harmful organism is propagated in the ocean, has become one of most important pollution of the sea.Water ballast destroys the ecosystem of halobiontic diversity and ocean, and causes enormous economic loss.China coastal waters and the coastal pilosity district that has become global red tide, as the China of shipping big country, the ocean environment harm that water ballast brings is particularly serious, and the improvement pressure that faces is also bigger.Following patent documentation and open source literature have disclosed some and have been used to administer the method for ballast water for ship biotic intrusion:
Open source literature Koichi Kamada when IEEE, 2004:707-712 show to use the runoff method, passes through if guarantee the seawater overflow of 3 times of water ballast volume of compartments, and then water ballast can diluted about 95%.Can rely on this method though seagoing vessel is changed water ballast in the pelagic realm, the runoff method exists weak point:
(1) time-consuming longer, expense is higher.The runoff method need be changed the seawater of 3 times of volume of compartments, needs the time longer.Open source literature World Shipping, 2003,26 (3) illustrate, according to the estimation of Australian communications and transportation office, change water ballast in the voyage at sea, goods per ton needs 0.17～0.30 Australian Dollar (for the purpose of abundant, goods per ton adds 0.06～0.30 Australian Dollar again).This expense depends on type of ship and size.Cost of labor and depletion charge also need to be affixed in the processing cost simultaneously.
(2) there is potential safety hazard.Because the runoff method needs boats and ships to be docked in the place, deep-sea, enforcement can threaten the stability and the structural strength of ship, and is subjected to the restriction of factors such as weather and sea situation, then can't implement for the boats and ships in some type and course line.The 40th sea environment-friendly of open source literature IMO can illustrate that runoff method/press over system makes the double-deck cabin ballast tank bilge bear big pressure, might cause the ballast tank water inlet.
(3) the 40th sea environment-friendly of open source literature IMO can illustrate, when using the runoff method, hydrobiont in the ballast tank settling and pathogenic agent are difficult discharges, and the ballast water exchange rate at each dead angle of ballast tank is lower.
Open source literature Satu Viitasalo, J.of Marine Env.Engg., 2005, when the 8:35-55 experiment shows the slightly salty of treatment with ultraviolet light (350W) low salt, when handling flow smaller or equal to 800l/h, for shell, cladocera, scratch planktonic deactivation efficient such as sufficient class and can reach more than 66%, and when flow was 200l/h, hydrobiological inactivation ratio such as cladocera is the highest can to reach 100%.
But according to open source literature World Shipping, 2003,26 (3) analysis, owing to contain a large amount of inorganics solutes in the seawater, the propagation of radiation wave in seawater also wanted slowly than clear water, it also may be subjected to organism solute, particle and influence of air bubbles.UV treatment relies on size and the form of microorganism to a great extent.The smaller biology of area/volume is difficult for the raying influence.In addition, uv-radiation may make the microorganisms transgenation that is subject to processing.
Open source literature Michael G.Parsons, Mar.Technol.2003,40 1:49-60 have disclosed the dominant technology in current ballast water treatment field, are about to mechanical separation and combine with uv-radiation or certain chemical treatment means.
