Abstract
The invention relates to a method for adding granular organic carbon in ballast water and relates to the field of ships. A certain amount of chitosan is added into seawater, wherein for each ton of high-salinity seawater, the additive amount of the chitosan is more than 1.05 to 1.95g; for each ton of medium-salinity seawater, the additive amount of the chitosan is more than 5.5 to 5.95 g; and foreach ton of low-salinity seawater, the additive amount of the chitosan is more than 5.25 to 5.7 g. The method can regulate the granular organic carbon content quickly and effectively, meet the requirement of a guide rule on the POC content of water for testing, and ensure that continental rise experiments can be performed effectively.
Description
Technical field:
The invention belongs to ship domain, be specifically related to the experimental technique of ballast for cruising water treatment.
Background technology:
From 2004, International Maritime Organizaton (IMO) passed through since " international shipping water ballast and settling control and management contract ", and the paces of Ballast Management system research and development have been accelerated in countries in the world." pact " regulation was from the beginning in 2009, and all new ships must be installed ballast water treatment plant, and existing ship is reviewed enforcement.And this device must pass through land-based test, obtains model approval, could install and go on board.
Ballast Management system approval guide rule (G8) is various countries authority competent authorities or its specified entity, whether satisfies " international shipping water ballast and settling control and management contract " regular D-2 specified standards in order to assessment Ballast Management system.The second section of guide rule (G8) annex wherein---test and performance specification that the Ballast Management system is approved; Test water to land-based test has very high requirement; The content of particulate organic carbon in the natural sea-water (POC) generally all is lower than above standard, and for example the annual POC content range in area, Jiaozhou Bay is at 55～410 μ g/L.The content that therefore need improve the particulate organic carbon of natural sea-water satisfies the requirement of guide rule.At present, the addition means that does not still have particulate organic carbon both at home and abroad.
Summary of the invention:
The addition means that the purpose of this invention is to provide particulate organic carbon in a kind of water ballast, it can fast and effeciently regulate the content of particulate organic carbon, satisfies the requirement of guide rule (G8) to test water POC content, guarantees that land-based test can effectively carry out.
In order to solve the existing problem of background technology, the present invention adopts following technical scheme: in seawater, add certain amount of chitosan, to the high salinity seawater, add amount 1.05～1.95g/t seawater of chitosan; Centering salinity seawater, amount 5.5～5.95g/t seawater of interpolation chitosan; To low salinity seawater, add amount 5.25～5.7g/t seawater of chitosan; To satisfy the requirement of guide rule (G8) to different salinity test seawater.
Described chitosan raw material is easy to get, cheap, environmental friendliness, and in seawater, can be evenly distributed rapidly, reduces experimentation cost effectively.
The present invention has following beneficial effect: can fast and effeciently regulate the content of particulate organic carbon, satisfy the requirement of guide rule (G8) to test water POC content, guarantee that land-based test can effectively carry out.
Description of drawings:
Fig. 1 is the structural representation that in the guide rule of the present invention (G8) land-based test test water is required;
Fig. 2 is the structural representation that the present invention is directed to the addition of different salinity seawater chitosan;
Fig. 3 is the structural representation of content that the present invention modulates POC in the inflow water of back different salinity.
Fig. 4 is the structural representation that the present invention adds seawater actual measurement SOC content behind the chitosan.
Embodiment:
Referring to Fig. 1-3, this embodiment adopts following scheme: in seawater, add certain amount of chitosan, to the high salinity seawater, add amount 1.05～1.95g/t seawater of chitosan; Centering salinity seawater, amount 5.5～5.95g/t seawater of interpolation chitosan; To low salinity seawater, add amount 5.25～5.7g/t seawater of chitosan; To satisfy the requirement of guide rule (G8) to different salinity test seawater; The chitosan raw material is easy to get, cheap, environmental friendliness, and in seawater, can be evenly distributed rapidly, reduces experimentation cost effectively.
This embodiment can fast and effeciently be regulated the content of particulate organic carbon, satisfies the requirement of guide rule (G8) to test water POC content, guarantees that land-based test can effectively carry out.
Embodiment 1: in 250t high salinity test seawater, add the 262.5g chitosan, the additive effect (see figure 4).
Embodiment 1: in 250t, add the 1.375kg chitosan, the additive effect (see figure 4) in the salinity test seawater.
Embodiment 3: in the low salinity test of 250t seawater, add the 1.312kg chitosan, the additive effect (see figure 4).
Claims (1)
1. the addition means of particulate organic carbon in the water ballast is characterized in that in seawater, adding certain amount of chitosan, to the high salinity seawater, adds amount 1.05～1.95g/t seawater of chitosan; Centering salinity seawater, amount 5.5～5.95g/t seawater of interpolation chitosan; To low salinity seawater, add amount 5.25～5.7g/t seawater of chitosan, make particulate organic carbon (POC) content in the land-based test test seawater satisfy the requirement of G8 guide rule just.
