EXHAUST GAS TREATMENT FACILITIES AND SYSTEMS WASTE TREATMENT The Group has strict monitoring and control on further strengthen the supervision of the wastes generated during the production hazardous waste. To coordinate with relevant process. Apart from complying with the policies, Inner Mongolia Company has national laws and regulations, Inner Mongolia formulated stricter treatment procedures to Company also formulates management handle hazardous wastes, including hyphae measures and emergency plans for handling slag, waste activated carbon, waste enzyme, different types of wastes. The wastes concentrated solution of phenylacetic acid, generated by Inner Mongolia Company could used mineral oil and concentrated liquid in be classified into two types, namely non- Mechanical Vapor Recompression (MVR). In hazardous wastes and hazardous wastes. order to reduce the amount of waste discarded, Inner Mongolia Company has The non-hazardous wastes include waste reused the recyclable hazardous wastes, such diatomite, sludge and glass generated by as concentrated phenylacetic acid, for Inner Mongolia Company during production, production. During the Year, Inner Mongolia as well as the general garbage generated in Comp a n y r e c y c l e d a l l c o n c e n t r a t e d daily operation. Inner Mongolia Company phenylacetic acid after undergoing several considers recyclable wastes as resources, tests. For the hazardous wastes that could not and collects and delivers them to the qualified be recycled, such as waste activated carbon, units for reuse, so as to effectively minimize waste enzyme, and concentrated liquid in the amount of wastes disposed. For example, MVR, treatment for turning them into harmless waste diatomite and sludge could be used to wastes was made through the boiler produce organic fertilizer and waste glass comprehensive treatment system of Inner could be used for recycling. Mongolia Company. The used mineral oil, which was sealed in barrels to ensure zero During the Year, the Country issued the leakage, was transferred to the unit qualified Gu i d i n g Op i n i o n s o n I mp r o v i n g t h e for hazardous waste treatment for subsequent Environmental Supervision Ability, Utilization treatment. The fermented fungi residue was and Disposal Ability and Environmental Risk delivered to the qualified unit to produce Prevention Ability of Hazardous Waste to organic fertilizers. 66 For the exhaust gas with peculiar smell generated in the sewage treatment process, the factories adopt a measure to collect the odor source in a sealed way. The c o l l e c t e d e x h a u s t g a s i s deodorized through the process of “multi-level alkali spraying + ozonation” to reduce the impacts on the surrounding environment. 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 fiber absorbing, low- t empe r a t u r e p l a sma , a l k a l i spraying and catalytic oxidation, so as to greatly reduce the emission of pollutants. I n o r d e r t o c o n t r o l t h e phenylacetic acid generated from fermentation plants and the peculiar odor emitted from the phenylacetic acid recycling process, Inner Mongolia Company adopts treatment processes such as the “cooling + alkali spraying + c a r bon f i be r ab s o r b i ng ” t o effectively prevent peculiar odor from spreading.
