摘要
运用加权平均法探讨城市的区域环境噪声评价值,提出将各功能区标准按面积(网格数)进行加权所得的平均值作为评价标准。同时探讨了工业排放的混合废水中污染物浓度均值的计算,提出用各工序的污染物浓度,按废水量进行加权的平均值作为计算结果。
Environmental noise standard of urban area was calculated by weighted average method according to the grid area (or number) and its standard. Pollutand concentration of mixing industrial wastewater was also calculated according to concentration and discharge of every technological process.
