| 摘要:随着城市化的推进，很多厂区距离居民区甚至市区较近，原本排放达标的排气对周边环境的影响越来越明显，如白色烟羽、腐蚀、恶臭（异味）等，部分地方环保开始要求工厂对纸机网部、密闭气罩的排风进行除臭、除雾处理。另外排风含湿量大，通过对气罩排风系统的水回收利用可大幅减轻整个项目用水量指标和废水处理的压力。 |
| Abstract:With the advancement of urbanization， many factories were even closer to residential areas and urban areas. The exhaust originally up to standard began to have more and more obvious impacts on the surroundings， such as white plume， corrosion， bad odor， etc. Some local environmental protection department even started to require factories to deodorize and demist exhaust from wet section and closed hood of paper machine. In addition， the exhaust contained a large amount of moisture， and recycling water through the air hood exhaust system could greatly reduce the entire project water consumption and pressure of wastewater treatment. |
