Description
Technical field
The present invention relates to a kind of water cause to smell the method and device of material total amount for measuring, belong to city water supply and sewage technology
Field.
Background technology
Drinking water odor problem is the current common problem of China, along with the requirement of the quality of drinking water is got over by people
Coming the highest, the odor problem in water has caused the great attention of people.1850, the U.S. was found that water body abnormal flavour first.
In May, 1969, there is serious drinking water abnormal flavour event in the Biwa Lake of Japan, have impact on kyoto, Japan, Osaka, the residence in area, Kobe
The people supply water.Generally, health will not be threatened by the odor in water, but people and other biological by perception these
Bad odor and avoid drinking.The different potableness not only affecting water with abnormal flavour of smelling in drinking water, the quality of infringement drinking water, and
And some compound producing bad odor also can directly damage health.
In China, many cities and towns all using lake, river is as main resource of water supply.In recent years, along with urban construction, work
The development of agricultural production and the increase of urban population, a large amount of raw sewerages and waste water enter natural water body, drinking water
The report of abnormal flavour gets more and more.In May, 2007, Taihu Lake blue algae bloom, in drinking water, odor problem is serious, have impact on Wuxi City several
100000 civic normal water, cause extensive concern both domestic and external." drinking water sanitary standard (the GB5749-that China is new
2006) clearly odor has been listed in " output water, pipe network water must survey project.
The source that in water body, odor produces is broadly divided into two classes: a class is abiogenous odor, mainly by organism in water
The odor caused such as algae, mushroom；One class is the artificial odor produced, and is mainly directly discharged into water by industrial wastewater or sanitary sewage
Odor or water factory caused by body carry out adding the odor caused by medicament when water processes.At present, main in drinking water resource
Causing to smell material is the artificial Organic substance produced.Conventional detection means is only capable of measuring the content of a certain material, measures cause and smells thing
The method of matter total amount is not yet set up, and causes to smell material total amount and the odor problem in water is more had directivity.
Summary of the invention
