Description
Technical field
The utility model relates to the water environment protection technical field, and specifically, the utility model relates to a kind of buoy that is used for drinking water source ground algae monitoring and warning.
Background technology
When being accompanied by China's rapid economic development, ecology environment continues to worsen.China's body eutrophication increasingly sharpens in recent years, and the harmful algal bloom that algae excessive propagation produces continues high frequency time to be taken place, and has badly influenced resident's aspects such as safe drinking water, aquaculture, water landscape value, has caused enormous economic loss.Taihu Lake blue-green alga bloom outbursts in 2007 influence life, the potable water water supply security in Wuxi, isoperimetric border town, Suzhou city, and Xiamen Jiulongjiang River dinoflagellate wawter bloom influenced Xiamen City's life, potable water water supply security in 2009.Big-and-middle-sized reservoir as main drinking water source ground also frequently breaks out wawter bloom, and only just there are 18 reservoir generation blue-green alga blooms in 2000-2009 Guangdong Province.Three Gorges Reservoir Xiang Xi He Ku gulf outburst dinoflagellate wawter bloom in 2009.
For tackling increasingly serious wawter bloom form, hydrographic office of Ministry of Water Resources issues " about carrying out the notice of algae monitoring pilot work " (No. (2008) 34, hydrology matter) in March, 2008, disposes algae monitoring pilot work.Chinese Ministry of Environmental Protection has issued " about the notice of further reinforcement distributing drinking water source ground environmental protection work " in September, 2010, has stressed the urgency of drinking water source ground protection.The algae monitoring has become the emphasis in the water quality monitoring work.
The method to the algae monitoring mainly contains following several kinds in the prior art at present:
1) microscopic method is measured cell number: the monitoring personnel need sample to the scene by ship and fix, and carry out the microscopy analysis by the professional after taking back the laboratory.
2) extraction is measured chlorophyll content: the monitoring personnel need spot sampling and filtering and concentrating, take back behind the laboratory with the acetone and other organic solvent extracting chlorophyll and measure.
3) on-the-spot fluorescence method is measured chlorophyll content: the monitoring personnel carry portable luminoscope knows the algae chlorophyll content to spot sampling and through the fluorescence intensity of measuring algal pigment, the existing different editions of measuring blue-green algae biomass and total algae bio amount of at present up-to-date luminoscope.
4) algal pigment fluorescence monitoring buoy: fluorimeter probe is integrated on the buoy, the algae bio amount in the continuous monitoring water body at the scene, and data wireless is transferred to base station on the bank.
5) wireless video monitoring buoy: Granted publication number has been mentioned employing wireless video shooting and monitoring blue-green algae change in concentration in the Chinese utility model patent of CN 201689088U.It installs monitoring camera on buoy, be used to take the photo in buoy waters, and transmission over radio is the base station ashore, judges whether to have taken place wawter bloom by the monitoring personnel according to the waters photo.
6) remote sensing survey algae bio amount: the optical spectrometer that carries via satellite comes large tracts of land to measure water colour spectrum, with the biomass of specific formulation estimation water body.
Yet there is following shortcoming respectively in existing algae monitoring technology:
1) microscopic method is measured cell number: sample has bigger property time lag from sampling the whole process of obtaining a result, and can not accomplish timely early warning.In addition, need the very personnel of specialty in microscopically algae classification and counting, and the efficient of analytic sample lower (generally speaking, a sample being carried out qualitative, quantitative analysis need 2 hours approximately simultaneously).
2) extraction is measured chlorophyll content: the extraction time of the back acetone and other organic solvent of sampling is longer, generally needs 1-2 days just can obtain data, can't accomplish timely early warning.
3) on-the-spot fluorescence method is measured chlorophyll content: though it is very quick to obtain data, fluorescence intensity and algae bio amount are no longer linear when algae density is higher, (for example to surpass 100 μ gChl/L), and the datum error that obtains is bigger.Solubilised state organic (CDOM) needs to eliminate the background fluorescence that CDOM sends and could obtain comparatively ideal data more for a long time in the water body.
4) algal pigment fluorescence monitoring buoy: though can accomplish unmanned, on-the-spot continuous monitoring, can't eliminate CDOM fluorescence in the water body to measuring the interference that produces, for the serious water body of a lot of eutrophication, this interference is very big.Algae density is higher when particularly wawter bloom taking place, owing to lost the linear relationship of fluorescence intensity and biomass, the resultant error that causes measuring is very big.
5) wireless video monitoring buoy: the scene photograph that comes through transmission over radio can only carry out very unscientific estimation to the algae in the water body, is not the quantitative analysis of precise and reliable.
6) remote sensing survey algae bio amount: the expense of buying satellite remote sensing date is very expensive, and needs very the personnel of specialty to carry out inverting just to obtain data.It aerial cloud, airborne floating dust etc. can directly influence the accuracy of remote sensing survey, need carry out the ground calibration.In addition, present international satellite remote sensing mainly focuses on marine field, and is very big for the remote sensing grid of fresh water environment, causes the precision of data not high.
Can know that to sum up above-mentioned existing technology such as microscopic method, extraction, on-the-spot fluorescence method etc. all can't be accomplished the unmanned continuous monitoring; The remote sensing method needs purchase data, receives weather effect very big; Wireless video monitoring buoy can't obtain the failure-free data; And the fluorescence monitoring buoy receives the influence of the organic and algae density of solubilised state in the water body easily.
