在常温条件下，采用Pasveer氧化沟，通过对氧化还原电位（ORP）、溶解氧（DO）、pH与进出水水质的相关性分析，发现碳氮比（C/N）、pH、ORP趋于稳定时对实验具有指示作用。实验结果表明：ORP稳定在60 mV附近，好氧区溶解氧稳定在0．2～0．4之间，两者具有良好的相关性；氧化沟去除碳氮（COD/TN）值为1．77，证明污水中短程SND起主要作用。

Under the normal temperature ,correlation analysis between ORP ,DO ,PH and the influent /effluent water quality was conducted in Pasveer oxidation ditch .The experimental results show that the C/N ,pH , ORP in the process have an indicative function to the entire experiment .The outcome indicates that ORP , when keeps stable at around 60mV ,has great correlation with the level of DO in the aerobic zone ,which keeps stable between 0 .2 and 0 .4 .What’s more ,the ratio of carbon to Nitrogen ,i .e .,COD/TN is equal to 1 .77 , which proves that short-cut SND plays a main role in the wastewater treatment .
