Technical Field

The utility model relates to the technical field of water dilution, in particular to a diluting, uniformly mixing and stirring device for measuring biochemical oxygen demand in water within five days.

Background

Organic matter bio-oxidation is a slow process that takes a long time to terminate. Therefore, the biochemical oxygen demand is measured by injecting water samples (or diluted water samples) into a plurality of glass bottles with water seals, measuring the daily dissolved oxygen content of one of the water samples, culturing each bottle in an incubator at 20 +/-1 ℃ for 5 days, and then measuring the dissolved oxygen content.

However, the existing device for measuring the five-day biochemical oxygen demand in water still has some disadvantages, when the traditional device for measuring the five-day biochemical oxygen demand in water is used for measuring the five-day biochemical oxygen demand in water, a stirring device is required to stir in the dilution process of a water sample, however, the existing device for measuring and stirring does not have unified regulations, and when most of stirring devices are used for stirring, the water sample is easy to generate bubbles to influence the measurement accuracy, so that the diluting, uniformly-mixing and stirring device for measuring the five-day biochemical oxygen demand in water is provided.

Detailed Description

The present invention will be further described with reference to specific embodiments for the purpose of facilitating an understanding of technical means, characteristics of creation, objectives and functions realized by the present invention, but the following embodiments are only preferred embodiments of the present invention, and are not intended to be exhaustive. Based on the embodiments in the implementation, other embodiments obtained by those skilled in the art without any creative efforts belong to the protection scope of the present invention. The experimental methods in the following examples are conventional methods unless otherwise specified, and materials, reagents and the like used in the following examples are commercially available unless otherwise specified.

Example (b):

as shown in fig. 1-4, a dilution and mixing stirring device for measuring biochemical oxygen demand in water for five days comprises a glass measuring cylinder main body 1, a base 2 is fixed at the bottom end of the glass measuring cylinder main body 1, a stirring barrel 3 is inserted in the glass measuring cylinder main body 1, a hole groove 4 is formed in the inner wall of the stirring barrel 3, a fixing seat 5 is fixed in the stirring barrel 3, the fixing seat 5 is connected with a long rod 6, a handle 7 is arranged at the upper end of the long rod 6, and a hook ring 8 is arranged on the handle 7.
