Inner Mongolia Company generates air pollutants in amount of emission does not exceed the legal the production process, including exhaust gas with a standard, Inner Mongolia Company has formulated peculiar smell generated from sewage treatment systems relating to pollutant monitoring. In addition process, exhaust gas generated from production to maintaining the automatic monitoring systems for process, phenylacetic acid exhaust gas generated relevant exhaust gases, the company has also from the fermentation process of phenylacetic acid commissioned a third party monitoring institution to recycling, smoke of coal-fired boiler and the exhaust regularly monitor the gas from pollution sources in gas emitted by the used motor vehicles. In regard to every month or quarter, so as to ensure that the the various types of exhaust gas, Inner Mongolia emission of exhaust gas complies with the Pollution Company has set corresponding treatment facilities Control Standard for Hazardous Wastes Incineration and systems to undergo recycling or purification (GB18484-2001). During the Year, Inner Mongolia treatment, and has implemented organic exhaust gas Company has conducted 4 quarterly monitoring of treatment projects, so as to ensure that all exhaust exhaust gas outlets, all of which met the standards, gas have reached the national emission standard and no excessive gas emissions occurred. before being emitted. In order to ensure that the Exhaust Gas Treatment For the exhaust gas with peculiar smell generated in the sewage treatment process, the factories adopt a measure to collect the odour source in a sealed way. The collected exhaust gas is deodorised through the process of “multi-level alkali spraying+ozonation” to reduce the impacts on the surrounding environment. 74 Removal of odours from sewage treatment processes In regard to the technical processes of different factories and the exhaust gas released, Inner Mongolia Company handle them by adopting treatment measures such as active carbon regeneration adsorbing, active carbon fibre absorbing, low-temperature plasma, alkali spraying and catalytic oxidation, so as to greatly reduce the emission of pollutants. Treatment of exhaust gases from different workshop processes In order to control the phenylacetic acid generated from fermentation plants and the peculiar odour emitted from the phenylacetic acid recycling process, Inner Mongolia Company adopts treatment processes such as the “cooling+alkali spraying+carbon fibre absorbing” to effectively prevent peculiar odour from spreading.
