石化废水回用于循环冷却水腐蚀影响因素研究

Study on the Factors Affecting the Corrosion of Petrochemical Wastewater in Circulating Cooling Water

本文对石化废水进行了水质全分析及有机污染物组成分析,同时研究了COD、BOD、NH_4^+-N对石化废水回用于循环冷却水的腐蚀影响。试验表明NH_4^+-N、BOD浓度对石化废水腐蚀的影响较大,石化废水回用应控制水中NH_4^+-N浓度小于4mg/L,、BOD浓度小于15 mg/L。

In this paper,the water quality and the composition of organic pollutants were analyzed,and the effects of COD,BOD and NH_4^+-N on the corrosion of petrochemical wastewater in circulating cooling water were studied. The results showed that the concentration of NH_4^+-N and BOD had a great influence on the corrosion of petrochemical wastewater,and the NH_4^+-N concentration of the wastewater was less than 4mg/L and the concentration of BOD was less than 15 mg/L.
