摘要：
Study on waste water containing chromium of continuous foam separation. In continuous foam separation,surface-active agent was inputted into the system at adding mode. Under certain height of liquid level,the influence of the height of chang-in, pH value of the wasterwater, the feeding speed of SDS, the charging capacity of Fe(NO(3))(3), gas flux and charge-in flux on foam flotation effect was investigated and the optimal parameters was obtained. The concentration of chromium ion was about 0.3mg.L(-1),COD was smaller than 100mg.L(-1). PH value was close to neutrality,which reach the Second Wastewater Discharge Standard of Country.
