Integrated Circuit Industry

To assess environmental feasibility of integrated circuit industry and predict it’s influence on air and acoustic emvironment, the current situations and impact assesment on air and sound environment were done. Survey on air pollution sources indicated that smoke dust was the main exhaust pollutants accounting for 88.5% of the total and SO2 was the second. Current situation of monitoring shows that all measured items can satisfy the requirements of the standards except the daily average concentration of PM10. Gas pollutants in waste gases can be removed 85~ 95% after purified. Noises on proposed project area during night and day are all accord with the third or fourth class standards of 《Standard of Environmental Noise of Urban Area》. Noises in the project can meet level Ⅲ standards of 《Standard of Noise at Boundary of Industrial Enterprises》. So this project has little influence on surrounding air and sound environment. Therefore on the condition of adopting corresponding treatment measures, this project is feasible on aspects of air and sound environment.

Integrated Circuit Industry

Power integrated circuit chip(ICC) is one kind of environmental material for energy saving. In order to analyze the reliability on environmental protection measures of integrated circuit industry, a proposed ICC project was taken as an example to investigate and analyze its engineering features and processing measures on production waste water, waste gas, waste solid and liquid, noise control and plant greening. It showed that there were 5 kinds of production wastewater containing acid & alkali, fluorine, ammonia, grinding impurity and organic respectively and 4 kinds of waste gases i.e. acid/alkali, organic solvent and process exhaust waste gases. Pollution treatment measures for wastewater, sewage and waste gases were mature technically and were effective with high efficiency. Treated wastewater can meet state discharge standards. Gas pollutants could be removed by around 90%. Dangerous waste solids and liquids would be delivered to the qualified company. Measures of vibration reduction, noise elimination, sound absorption and insulation etc. would be taken to control noises from power station and create a good environment. This work is an indispensable part of environmental impact assessment on IC industry.

Urban acoustic environment, especially noise pollution, is a product of rapid urban development and urban scale expansion. It is one of the urgent environment problems in current urban planning and governance. This study analyzes the spatiotemporal changes of acoustic environment in the functional areas of cities above prefectural level based on the geographical perspective in China. The results shows that the higher urban level is, the more active acoustic environment in the functional areas will be; otherwise, the quieter it will be. The spatial variation of the acoustic environment in the functional areas in the east is generally higher than in the west, and the coastal areas is higher than interior during day and night, which is generally consistent with the spatial distribution characteristics of China's social and economic development. The influence factors of urban acoustic environment are multiple, the development of urban social economy has a significant influence on urban acoustic environment, and the factors like environmental protection consciousness of residents, environmental governance level of the city have a significant influence on urban acoustic environment. Therefore, the governance measures of urban acoustic environment should be more diversified.

AbstractIn the guidelines about the management of areas of good environmental noise quality recently published by the European Environment Agency (EEA) it is suggested to combine different methodologies, like noise mapping, sound level measurements and the soundscape approach. Such a recommendation has started to be recognised by a number of local authorities in Europe that are gradually integrating a holistic concept into their environmental noise policies. This research aimed to explore and demonstrate the possibility to integrate conventional noise mapping methods and soundscape methods in an actual urban redevelopment project. A case study was made using the Valley Gardens project in Brighton & Hove (UK). Different scenarios of sound-pressure level distributionswere simulated for both traffic sound sources (i.e. noise maps) and natural sound sources (i.e. sound maps). Additionally, individual responses about the sound environment of the place collected during an on-site question survey were used to implement soundscape maps.The overall picture revealed that the road traffic noise should be reduced, but also it is feasible that preferred sounds likewater features or birdsong could be introduced to make the sound environment more appropriate for the place. Generally, within the framework of this research, noise maps, sound maps and soundscape maps were used together to "triangulate" different layers of information related to the acoustic environment and the way it is perceived, providing a possible working procedure to consider for planners and policy-makers in the future.
