Technical Field

[0001] The utility model belongs to the technical field of reagent bottles, in particular to a reagent bottle for rapid determination of ammonia nitrogen in effluent from domestic sewage. Background Art

[0002] Nitrogen is one of the main elements that make up the proteins of organisms, and is also one of the main culprits of eutrophication of water bodies. Nitrogen exists in sewage in various forms. Ammonia nitrogen exists in the form of ammonia, including free ammonia and ionized ammonia, as well as nitrite nitrogen, nitrate nitrogen and organic nitrogen. Among them, ammonia nitrogen is one of the main control indicators of effluent from sewage treatment plants. At present, most of the domestic urban domestic sewage treatment plants refer to the "Nessler's Reagent Spectrophotometric Method for the Determination of Ammonia Nitrogen in Water Quality" HJ535-2009 when determining ammonia nitrogen in water. However, such national standard methods require large instruments and equipment such as spectrophotometers, and the detection process also needs to be completed in the laboratory, which is not convenient to carry to the site for rapid determination.

[0003] The rapid detection of ammonia nitrogen in water in the prior art usually tends to be biased towards the rapid determination of ammonia nitrogen in drinking water, and some of them ignore the storage requirements of Nessler's reagent and potassium sodium tartrate solution used in ammonia nitrogen detection, as well as the fact that the test equipment is too large to be carried.

[0006] Furthermore, a rubber sleeve is provided on the measuring bottle, and the circumference of the storage rubber shell is arranged on the rubber sleeve.

[0007] Furthermore, a plurality of rubber plates are arranged on the circumference of the rubber sleeve, and the rubber plates are provided with openings for placing test tubes.

[0008] Furthermore, a receiving groove corresponding to the placed rubber sheet is opened on the outer circumference of the rubber sleeve, so as to receive the placed rubber sheet when the placed rubber sheet is bent and folded toward the receiving groove.

[0009] Furthermore, the storage plastic shell is made of light-shielding material.

[0010] Furthermore, a shading cloth is provided on the outer circumference of the measuring bottle.

[0011] Preferably, a bottom sleeve is provided at the bottom of the measuring bottle, a connecting ring is slidably connected to the measuring bottle, the shading cloth is connected between the bottom sleeve and the connecting ring, a contact convex edge is fixedly connected to the inner wall of the rubber sleeve, a gap is left between the inner wall of the rubber sleeve and the outer periphery of the measuring bottle through the contact convex edge, and the shading cloth is located in the gap.

[0012] Furthermore, a resistance plate corresponding to the placement rubber plate is fixedly connected to the circumference of the connecting ring.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The utility model stores two reagents in independently packaged reagent tubes one and two for single use, is simple to operate and easy to carry, and can realize rapid detection of ammonia nitrogen by using in combination with a measuring bottle with scale lines; and by providing a storage plastic shell, and opening two storage cavities on one storage plastic shell, the reagent tube one and the reagent tube two required for one determination can be placed in the storage plastic shell together, and thus can be conveniently taken out; and the device can improve detection efficiency during determination and detection by providing a placement plastic plate and a shading cloth, and can shield the reagent tube one and the reagent tube two from light through the provided storage plastic shell, effectively preventing the reagents in the reagent tube one and the reagent tube two from being directly exposed to sunlight; therefore, the device reduces the volume of the equipment for ammonia nitrogen detection through a lightweight and miniaturized design, and is easy to carry and use.
