| Abstract: |
| The research on pollutants producing coefficient is one of the bases of the Second National Pollution Source Survey. In this study, two factories that produce glufosinate pesticide using the Grignard technology were selected for sampling and investigation. Based on the experimental measurement method for waste water and the material balance algorithm for waste gas, the individual and whole pollutants producing coefficient were calculated, and we analyzed the difference in influencing factors of pollution production between the two factories. The results showed that the individual pollutants producing coefficient in Factory A were chemical oxygen demand 1.09×106 g·t-1, ammonia nitrogen 969 g·t-1, total nitrogen 2.10×103 g·t-1, total phosphorus 750 g·t-1, volatile organic matter 1.59×103 kg·t-1; the individual pollutants producing coefficient in Factory B were chemical oxygen demand 2.34×106 g·t-1, ammonia nitrogen 53 g·t-1, total nitrogen 795 g· t-1, total phosphorus 124 g·t-1, volatile organic compounds 335 kg·t-1. The whole pollutants producing coefficient of glufosinate were chemical oxygen demand 1.73×106 g·t-1, ammonia nitrogen 499 g·t-1, total nitrogen 1.43×103 g·t-1, total phosphorus 429 g·t-1, volatile organic matter 748 kg·t-1. Through the in-depth analysis of the influencing factors of the pollutants producing coefficient in the two factories, it was found that the differences between the use of raw and auxiliary materials, organic solvents, and equipment were the main factors on the pollutants producing level. |
