摘　　要：研究了焦亚硫酸钠、亚硫酸氢钠、亚硫酸钠、连二亚硫酸钠、硫代硫酸钠等还原剂处理含铬废水。试验确定了各种还原剂的最佳加药量,并比较其经济性,通过比较,焦亚硫酸钠作还原剂效果最佳。The reduction properties of five reducing agents ： Na2S2O5 , NaHSO3 , Na2SO3, Na2S2O4 and Na2S2O3 , in treating chromium containing wastewaters are investigated. The optimum dose of the chemicals is determined through tests and economy of these five reducing agents is compared. Finally Na2S2O5 is best as the reducing agent through comparison.
