Description
Technical field
The utility model relates to technical field of drinking water treatment, and in particular to the sxemiquantitative of Mn (II) content in a kind of water body
On-line measuring device and its detection method.
Background technique
When Manganese in Drinking Water content is more than 0.05mg/L, such as pipeline accumulation of deposits can be generated, water quality jaundice black and
A series of problems, such as metal astringent taste is generated when drinking.And the exceeded drinking water of manganese is taken in for a long time and will also result in the degeneration of human nerve member
And motility dysfunction.Therefore, various countries have all worked out relatively stringent limit standard, European Union and beauty to the manganese content in drinking water
Environmental Protection Agency, state limit value is 0.05mg/L (China's limit value is 0.10mg/L).
Manganese in raw water mainly exists in the form of II valence or IV valence, and wherein Mn (IV) exists mostly in the form of suspended matter, can be
It is removed in coagulating sedimentation, the manganese of dissolved state is mainly Mn (II), is the key substance removed in production.Current water factory processed is most
Using potassium permanganate oxidation demanganization process, Mn (II) is oxidized to Mn (IV) using potassium permanganate, then is removed by coagulating sedimentation,
Its theory reaction is than being 1.92mg KMnO4/mg Mn(Ⅱ).But due to also containing other reducing substances in raw water, lead to height
The practical dosage of potassium manganate is difficult to accurately hold.It will lead to output water manganese content when potassium permanganate throwing amount is insufficient or excessive
It is exceeded, therefore how to judge that the suitability of potassium permanganate throwing amount is a major issue in need of consideration in the aquatic production of system.
Conventional method is the manganese content detected in raw water and output water respectively, judges potassium permanganate further according to testing result
