一、概述我厂主要加工任丘原油,自实现了常压渣油催化裂化新工艺及分馏塔顶采取注氨措施以来,含硫污水中硫化物及氨氮含量一直较高,PH 值达9以上。一九八三年污水氧化脱硫装置投产后,未能完全满足工艺要求。一九八四年又建了一套含硫污水单塔加压汽提装置,因未上抽氨设施,所以只能脱除 H_2S。含硫污水中硫 First, an overview of our main processing Renqiu crude oil, since the realization of the new technology of atmospheric residue and catalytic cracking of the top of fractionation tower to take ammonia measures since the sulfur content of sulfur and ammonia nitrogen in sewage has been high, PH value of 9 or more . After the effluent oxidation desulfurization unit was put into operation in 1983, it failed to fully meet the technological requirements. In 1984, another set of single-tower pressurization stripping unit for sulfur-containing wastewater was built. Since ammonia removal facilities are not installed, H_2S can only be removed. Sulfur in sulfur-containing sewage
