Description
Technical field
The utility model relates to sewage detection technical field, in particular to a kind of biochemical oxygen-demand rapid measuring instrument sample introduction
Disk.
Background technique
Biochemical oxygen demand (BOD) is also known as bod, refers to the aerobe in water in certain temperature by the organic matter in water
Dissolved oxygen content required for inorganic matter is resolved into during this, is indicate the aerobic pollutions matter content such as Organic substance in water one
A overall target.
In laboratory, generallys use biochemical oxygen-demand rapid measuring instrument and aerobic pollution matter content in water is detected,
And biochemical oxygen-demand rapid measuring instrument detects the aerobic pollution matter content in water using Microbe probe, by micro- life
Object film is anchored on diaphragm type oxygen electrode i.e. composition microorganism electrode, and instrument is using circulation measurement method, by circulation measuring cell group
Part immobilized microbial membrane.Since the output electric current of oxygen electrode is directly proportional to the content of dissolved oxygen, when the liquid for being free of any organic matter
When body (buffer solution) passes through flow cell, the assimilation very little of microorganism, thus almost do not have through the dissolved oxygen of microbial film
It is reduced.When the appearance liquid containing organic matter passes through flow cell, the assimilation of microorganism becomes Showed Very Brisk, and consumption is more
Dissolved oxygen, then result in through microbial film dissolved oxygen content reduction.The variation of this dissolved oxygen content directly makes oxygen electric
Pole output generates variation on year-on-year basis, turns out the output current variation value relationship directly proportional to sample content of organics, interchangeable accordingly
Calculate the biochemical oxygen demand (BOD) of sample.
