摘要
建立一种只需测定工业废水中化学需氧量(简称COD_(Cr)),就可推算出生化需氧量(BOD_5)的方法;对21个样品进行分析测定COD_(Cr)和BOD_5,经线性回归找出两者的相关性;试验表明COD_(Cr)和BOD_5间具有良好的线性相关性,其中r=0.9958;该方法应用于制药工业废水的处理和控制,具有简便、适应性好、省时省力等优点。
Set up an only method that if chemical oxygen demand in industrial efluent (it is called CODCr for short) was estimated, then five days'biochemical oxygen demand (it is called BOD5 for short) would be work out. Making CODCr and BOD5 of analytical determination point at twenty - one proof sample. Correlation between two passes through linear regression curve was found out. It showed there have good correlation between CODCr and BOD5, among which r=0.9958. The method was applied to palatial industrial effluent treatment and control, having simple, good compliance and save time and save labor act advantage.
