Abstract:

In order to study the environmental impact of coal gangue power industry, took Expanding Project of Heilongjiang Dadong Coal Gangue Power Plant (EPHDCGPP) as an example to analyze its pollution. According to the requirements of Chinese environmental assessment and its project situation, analyzed its features of technology process and possible pollution of present plant and expanding project such as noise, dust, smoke, SO2, waste water and waste solid etc. Accident risk analysis was also done. Moreover, the intensity of polluting source were confirmed as 676.5 t/a of smoke dust and 680 t/a of SO2. All 7.6×104 t/a of ash and 2.23×105 t/a of slag will be sold to a local cement plant. Noises on boundary less than 50 dB(A) in day time and 45 dB(A) during night. There will no waste water discharge after expanding project. Meanwhile, measures to prevent above-mentioned pollution were proponed. This would lay a sound foundation for environmental impact assessment.
