【摘要】 本文对煤气污水的COD构成进行分析研究,测定煤气污水中无机组分和有机组分的含量,确定了各组分及悬浮物的COD当量,结果表明煤气污水COD主要由污水中的无机组分、有机组分、悬浮物提供。进水中无机组分10.90%,有机组分66.65%,悬浮物8.49%,总和86.04%;出水中无机组分3.74%,有机组分27.06%,悬浮物39.34%,总和70.14%。更多还原

【Abstract】 The compositions of COD in wastewater from coal gas supply system was investigated,both of inorganic and organic constituent in above mentioned wastewater were calculated and equivalent weight of COD in the two continents were quantified,the results shows that COD in mentioned wastewater mainly composed up of both of inorganic and organic constituents and SS.the rate of inorganic,organic constituents and SS were 10.90%,66.65%,8.49% in influent respectively the total loads summed up 86.04% and that of inorganic,organic constituents and SS were 3.74%,27.06%,39.34% in out fluent respectively,the total loads summed up 70.14%.更多还原
