First, fingerprint construction that offal characteristic and chemistry make up, carry on the investigation to extant offal treatment industry, to set up fingerprint materials, significant manufacture procedures about offal treatment industry. its content includes： 1.Collect and analyze offal treatment industry original supplies, manufacture procedures, pollution abatement facilities data to set up the sieve principle. and finally, according to the principle to select the factories to be investigated. 2. Use materials safety data sheet (MSDS) of material to confirm main composition and secondary composition of sample. 3.The physical property, harmful characteristic (composition): fill in table 2.2-1 and 2.2-2, and investigating and measuring simple and easily test (determine its pH value , the fire flashes point ……). 4.According to above-mentioned from (1) to (3) data that collect, to fix a plan about sample target and sample principle that quantity assign to sieve, and write the prospectus according to this principle, plan to gather 50 samples of 10 factories at least. The prospectus should also be in order to carry out after handing over our institute and verifying, passing in 30 days before. 5. To set up chemistry composition of the materials: Sample gathered, make in accordance with it manufacture procedures or offal source carry out organic and analysis of inorganic respectively, make by it manufacture procedures or offal source can judge sample inorganic composition or at the organic composition only, must only carry on the inorganic or organic analysis, it is analyzed that samples are counted and can#t be less than 45. Divide and state it as follows: 6. All screening, half quantitative TIC scan atlas and other atlas should be set up in the disc: 7.Collect data of relevant offal treatment industry procedures and compile fingerprints of chemistry characteristic and chemistry make up. finally, write the evaluation and analysis report of fingerprint.
