摘要: 根据对稀释配制的亚硫酸制浆废液(中段水)进行曝气,测定不同时间CODcr的值,通过数据图解处理法得到可生化化学耗氧量(CODB)。经与同批样品实测BOD5值进行换算,对其平均值结果进行方差分析。结果表明:误差结果为9.26%,即由作图法测定的CODB值与BOD5测试法的值非常接近,对亚硫酸制浆废液的生化处理研究具有实际意义。

关键词: 亚硫酸制浆废液, CODB, BOD, 相关性

Abstract: Exposed sulphurous acid pulping wastewater diluted to the air,the chemical oxygen demand(COD_(Cr)) values in different times were determined,and the biodegradable chemical oxygen demand(COD_B) was obtained by data illustration method.COD_B value was transformed with the biological oxygen demand(BOD_5) measured value from same samples and the mean values were analyzed by variance analysis.The results indicated that the average error was 9.26%.That is to say,COD_B value with data illustration method was similar to that of BOD_5 determination method,which was significant to biochemistry treatment of sulphurous acid pulping wastewater.
