Abstract
The invention is a method to detect the number of jianshuizao-type pelagians in water. The method: firstly placing a beaker holding water sample to be detected on a deep-colored bottom surface, horizontally placing a fluorescent tube above the beaker, where the tube is set in the direction of tangent line of the side wall of the beaker; then using glass stick to lightly blend 3-4 times along the inner wall of the beaker, stopping for 1minute, and then the operating personnel can observe and record the number of pelagians in the water over the beaker in the other side of the tube corresponding to the beaker. It is simple and convenient to operate and has extremely high feasibility.
Description
Technical field: the present invention relates to a kind of detection method for cyclops class animal plankton individual amount in the water.
Background technology: the eutrophication of water body provides living space in a large number for the cyclops class, and human excessive fishing becomes the power of cyclops rapid growth.In water factory's clear water reserviors of some large-and-medium size cities of China and even pipe network water, all once found cyclops, even the accident of cyclops took place to occur in a lot of pipe network water.Bigger cyclops naked eyes as seen, like the white meat worm, it occurs in the water of registering one's residence, and has not only violated in the drinking water sanitary standard the regulation of sensory properties index, has brought bad organoleptic effects to the user, what is more important, most of Cyclopoidas are the vectors such as pathogenic organisms in the water such as blood fluke, nematode, thereby become a pathophorous important media, have brought very big threat for people's water safety, therefore, must from potable water, remove effectively.At the problems referred to above, researcher begins to note studying the method for removing cyclops class animal plankton in water treatment procedure, but the detection of its individual amount is the difficult point in the research process all the time, how to detect its individual amount rapidly and accurately, accelerate research speed, and making experimental data more credible, is a problem demanding prompt solution.
Summary of the invention: the object of the present invention is to provide a kind of simple, intuitively to the detection method of cyclops class animal plankton individual amount, concrete grammar is: at first the cylindrical shape beaker 1 with splendid attire water sample to be measured places on the dark colour bottom surface 2, oblique upper at beaker 1 is horizontally disposed with a fluorescent tube 3, fluorescent tube 3 is the tangential direction setting with beaker 1 sidewall, the accurate position of this fluorescent tube need meet following two conditions simultaneously: the line L at the center of a. fluorescent tube 3 and beaker 1 end face center and the angle α of beaker end face 1-1 are 45 °, and b. fluorescent tube 3 is 20cm with the shortest horizontal range H of beaker 1 outer wall; Stir gently 3～4 times with the inwall of glass bar then along beaker 1, after static 1 minute, on the opposite side position of the beaker 1 corresponding with fluorescent tube 3, operating personnel directly over beaker 1 with the naked eye in the observational record water quantity of animal plankton get final product.The present invention can detect the individual amount of the cyclops class animal plankton in the water outlet quickly and accurately, thereby helps carrying out of follow-up study work.In addition, use method of the present invention, simple to operation and effective, have high feasibility.
Description of drawings: Fig. 1 is a structural representation of the present invention, and Fig. 2 is the left view of Fig. 1.
Embodiment one: the detection water quality of present embodiment for contain the cyclops individual amount 1～20/rise in the scope, permanganate index is less than 10mg/L, turbidity is less than the water sample of 30NTU.Its detection method is: at first the cylindrical shape beaker 1 with splendid attire water sample to be measured places on the dark colour bottom surface 2, bottom surface 2 is the purple of 20cm * 10cm, black or blue paperboard, the water sample to be measured of institute's splendid attire is 1L in the beaker 1, be horizontally disposed with the fluorescent tube 3 of a 40W at the oblique upper of beaker 1, fluorescent tube 3 is the tangential direction setting with beaker 1 sidewall, the accurate position of this fluorescent tube need meet following two conditions simultaneously: the line L at the center of a. fluorescent tube 3 and beaker 1 end face center and the angle α of beaker end face 1-1 are 45 °, and b. fluorescent tube 3 is 20cm with the shortest horizontal range H of beaker 1 outer wall; When needs are strengthened light, the incandescent lamp 4 of a 60～100W can be set at the middle lower position in beaker 1 outside, the position accurately is set should satisfies following two conditions simultaneously of incandescent lamp 4: beaker 1 axis 1-2 is arrived at a. incandescent lamp 4 centers to the vertical line section K of beaker 1 axis 1-2 and fluorescent tube 3 centers vertical line section M in vertical state, b. incandescent lamp 4 front ends are 5cm with what close on beaker 1 outer wall most apart from N, before the detection, stir gently 3～4 times with the inwall of glass bar earlier along beaker 1, static 1 minute, when most of cyclopss moved about under the hydraulic action to beaker when central authorities, on the opposite side position of the beaker 1 corresponding with fluorescent tube 3, operating personnel directly over beaker 1 with the naked eye in the observational record water quantity of animal plankton get final product.Need to observe counting continuously more than 3 times, average as last measured value.
Embodiment two: when the flea excessive concentration, elder generation's water with water sample to be measured be diluted in the water cyclops individual amount 1～20/rise in the scope, method by embodiment one detects again, then testing result be multiply by extension rate as net result.
