Description
Technical field
The present invention relates to technical field of environmental detection, and in particular to the quick detection of organic solvent in organic wastewater.
Background technology
Currently, water resource pollution is that countries in the world generally face one of urgent problem.According to the United Nations's world resource
Research institute's research report, World Water money all suffer from office all more severe than other resources and than ever in terms of quality and quantity
Face.The water resource in China also faces serious pollution problem.Industry Waste of the organic wastewater essentially from industries such as pharmacy, chemical industry
Water, generally directly affect the COD of organic wastewater, and these containing a variety of residual organic solvents, the height of its concentration
Waste water is easily enriched with the microbial body of processing waste water, it is difficult to metabolism discharge, suppression and toxic action is produced to microorganism so that
Biochemical treatment is difficult to.《Chemical synthesis class pharmaceuticals industry pollution discharge standard》In 1 day August in 2008
Implement, wherein COD discharge standard is reduced to 120 mg/L by 300 original mg/L, and this makes the wastewater treatment of pharmaceutical industry
Face great challenge.Therefore, the residual organic solvent in organic wastewater is monitored and controlled, can effectively improved organic
The treatment effect of waste water, realizes qualified discharge.At present, it is the most frequently used come to detect the method for organic solvent in organic wastewater be gas phase color
Spectrometry, such as today in 2010 in chemistry, Han Ming lives et al. is remained using headspace gas chromatography to determine in pharmacy waste water
Organic solvent；In the modern chemical industry of 2012, Hou Xiaohong et al. is also with Headspace Gas Chromatography organic wastewater
In a variety of residual solvents content.
Raman spectrum is a kind of scattering spectrum, and it can provide quick, simple, repeatable and more importantly not damaged
Qualitative and quantitative analysis, it directly by fibre-optical probe or can pass through glass, quartz and optical fiber without preparation of samples, sample
Measurement.Since Raman spectrum is found, it is important that the technology has been applied successfully to chemistry, environment, biology, medicine, material etc.
Field.There is presently no the report that Raman spectrum carrys out organic solvent content in quick detection waste water.
The content of the invention
It is an object of the invention to provide a kind of side of organic solvent content in portable Raman quick detection organic wastewater
Method, to realize quick discriminating, have the advantages that without pre-treatment, quick, efficient, lossless, convenient.
In order to reach above-mentioned purpose, solution of the invention is：
The method of organic solvent content, comprises the following steps in a kind of portable Raman quick detection organic wastewater：
1st step, the foundation of standard spectrum picture library
The neat solvent for the organic solvent for being possible to use using Portable Raman spectrometer detection, obtains the standard of neat solvent
Raman peaks, and be entered into spectrogram storehouse, establish a standard spectrum picture library；
2nd step, the detection of waste water
Directly wastewater sample is detected using Portable Raman spectrometer, obtains the Raman peaks of waste water；
3rd step, the analysis and processing of data
The standard spectrum picture library that the Raman peak data and the 1st step of the waste water that 2nd step is obtained are established is compared, that is, obtains in waste water
The species and content of organic solvent.
After such scheme, the present invention is not required to carry out pre-treatment to sample, is not required to add other internal standard compound, by useless
The Raman peak data and standard spectrum picture library of water are compared, can quickly, efficiently, nondestructively realize to the organic solvent in waste water
Detected, so as to effectively improve the treatment effect of organic wastewater, realize qualified discharge.
Brief description of the drawings
Fig. 1 is the standard Raman spectroscopy figure of part neat solvent in spectrogram storehouse；
Fig. 2 is the Raman spectrogram of waste water.

3. the foundation of standard spectrum picture library
A standard spectrum picture library is established first with Portable Raman spectrometer, by the organic solvent for being possible to use
The normalized Raman peak of neat solvent is all entered into the spectrogram storehouse.If Fig. 1 is neat solvent N, N '-dimethyl formamide, dimethyl are sub-
Sulfone, ethanol, the Raman spectrogram of toluene.
4. sample determines
Directly wastewater sample is detected with portable Raman.Obtain the Raman peaks of the waste water shown in Fig. 2.
5. data process＆analysis
The Raman data of acquisition and standard spectrum picture library are compared, obtain the species and content of organic solvent in waste water.By
The solvent for finding to contain in the waste water after comparison is that N, N '-dimethyl formamide, and content are 5.02%.
