Description
Technical field
The utility model relates to a kind of aerator, is specifically related to the quick aerator of a kind of five-day BOD use for laboratory, belongs to water-treatment technology field.
Background technology
Along with people are to the pay attention to day by day of environmental protection, national environmental protection portion is also more and more higher for the requirement of water quality protection and purification, and what drive is the fast development of environmental monitoring technology simultaneously.
Biochemical oxygen demand refers under prescribed conditions, and microbial decomposition exists the amount consuming dissolved oxygen DO in the Biochemical processes that some oxidizable substance, particularly organism in water carry out.Therefore, five-day BOD has become one of routine monitoring project as the important indicator weighing water pollution degree, and detection method GB/T 7488-87 water quality five-day BOD (BOD
5) mensuration dilution with inocalation method be the most frequently used method.
In GB/T 7488-87, the preparation of dilution water is most important, and its Main Means prepared is carrying out aeration to distilled water exactly, makes the dissolved oxygen DO of dilution water at least reach 8 mg/L.But which kind of aerator is regulation do not use in this standard, in normal experiment, everybody commonly uses the oxygen machine that exposes to the sun of breeding fish, but does not have the supporting oxygen bottle that exposes to the sun, poor sealing, therefore efficiency is not high, if expose to the sun with air aeration within 10 hours, also often do not reach the requirement of large 8 mg/L of dissolved oxygen DO; If use high-purity compressed oxygen cylinder to carry out aeration can reach requirement in about 2 hours, but cost is higher.
Therefore, need, to a kind of aerator of lab design, economy to reach requirement of experiment fast.
Utility model content
For the defect of above-mentioned existence of the prior art, the purpose of this utility model is to provide a kind of five-day BOD quick aerator, and it can reach the requirement of the dissolved oxygen DO of Water In The Experiment fast, and efficiency is high, and cost is low.
For realizing the object of fast energy-saving aeration, the utility model have employed following technical scheme:
The quick aerator of five-day BOD, it comprises an aeration bottle and aeration mechanism, the sidewall of described aeration bottle is provided with sample tap and a relief port, described aeration mechanism comprises an aeration head, the disk that described aeration head is provided with a plurality of circular hole by a surface forms, described aeration head is arranged at the inside of aeration bottle, and is connected with one end of a connecting pipe, and the pneumatic pump that the top oral area and that the other end of described connecting pipe stretches out aeration bottle is arranged at aeration bottle outside is connected.
Preferably, described aeration bottle is a cylindrical glass bottle.
As one of preferred version of the present utility model, described sample tap is arranged at aeration bottle one sidepiece near 3cm place, bottom.
As one of preferred version of the present utility model, described relief port is arranged at aeration bottle one sidepiece near top end.
Preferably, the top oral area of described aeration bottle being provided with the rubber plug of a middle with hole, described rubber plug being inserted with one for connecting the link of draft tube.
More specifically, described link is a glass tube.
Compared with prior art, the beneficial effects of the utility model are:
(1) structure is simple, convenient carrying.
(2) simple to operate.
(3) efficient, energy-conservation, cost is low.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model architectural feature and technical essential, below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Fig. 1 is the structural representation of the quick aerator of five-day BOD of the present utility model.
Description of reference numerals: 1-aeration bottle, 11-sample tap, 12-relief port, 21-aeration head, 22-connecting pipe, 23-pneumatic pump, 21a-circular hole.
Embodiment
Below in conjunction with accompanying drawing and a preferred embodiment, the technical solution of the utility model is further described.
As shown in Figure 1, be a preferred embodiment of the present utility model, the quick aerator of a kind of five-day BOD, it comprises an aeration bottle 1 and aeration mechanism.Described aeration bottle 1 is the cylindrical glass bottle of a thickening, at aeration bottle 1 sidewall, bottom 3 centimeters is provided with a sample tap 11, described sample tap 11 is provided with internal diameter rotary switch, with easy to exhaust, water intaking and emptying, offers a relief port 12 at aeration bottle 1 sidewall near the position on top; Open a ground on aeration bottle 1 top, and join the rubber plug of a middle with hole, plug in the glass tube of one section of 8cm in rubber consent, respectively expose 3 cm up and down, for reeve tracheae.
Described aeration mechanism comprises an aeration head 21, described aeration head 21 is arranged at the inside of aeration bottle 1, and be connected with one end of a connecting pipe 22, the pneumatic pump 23 that the top oral area and that the other end of described connecting pipe 22 stretches out aeration bottle 1 is arranged at aeration bottle 1 outside is connected.Described pneumatic pump 23 is a microdiaphragm pump pneumatic pump, and connecting pipe 22 can be a flexible pipe.Aeration head 21 is made up of the disk of a surface by hundreds of aperture size circular hole 21a.
During work, sample tap 11 and relief port 12 are closed, open pneumatic pump 23, expose to the sun into air, disk by expose to the sun into air refinement, be then uniformly dispersed, increase the contact area with water, greatly improve absorption efficiency; Meanwhile, due to airtight in aeration bottle 1, along with air expose to the sun into, air pressure in aeration bottle 1 can increase within the specific limits gradually, and from vapor-liquid equilibrium relationship, the oxygen being dissolved in dilution water can increase sharply, thus meet the demands within the time faster, improve conventional efficient.Relief port 12 is opened, in case pressure is excessive every 15 minutes.When aeration just can be met the dilution water of requirement after 2 hours, when aeration is after 2 hours, the relief port 12 of aeration bottle 1 upper end is opened a crack gently, slowly exits, simultaneously aeration 15 minutes again, stop when inside and outside pressure balanced.The water that aeration completes, can directly take out from sample tap 11.
In sum, the utility model structure is simple, and convenient carrying, simultaneously simple to operate, work efficiency is high, energy-conservation, with low cost, can meet the oxygen level needs in laboratory fast.
Above-described embodiment is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and implement according to this; protection domain of the present utility model can not be limited with this; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
