The following analysis was obtained for an industrial wastewater sample. Using this information estimate the ultimate oxygen demand.
organic carbon=300mg/L
organic nitrogen=25 mg/L
ammonia nitrogen=15mg/L
nitrite nitrogen=15mg/L
谁会答啊?

Ultimate Oxygen Demand
定义:水中有机物质(包括含C和含N有机质)氧化的理论需氧量,即称之为极限需氧量(UOD),或长期需氧量。此时,水体中所有有机物质均被完全氧化生成CO2、H2O和NO3-。
Equation for calculation of UOD:
UOD = 2.67×org.-C + 4.57×(org.-N +NH3-N)+1.14×NO2-N
方程式。。。
唔明白。。。。没有学过。。。
真的很不明白哦~~
2.67(300)+4.57((NH4-N)+25)+1.14(15)
UOD = 2.67×org.-C + 4.57×(org.-N +NH3-N)+1.14×NO2-N
=2.67(300)+4.57(25+15)+1.14(15)
=801+182.8+17.1
=1000.9
