摘　　要：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60mV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.
