TL;DR: According to the Fenton reaction principle, chemical adsorption and chemical flocculation, chemical oxygen demand (COD) and Cr6+ in the wastewater were reduced in this article.
Abstract: The paper aims to find out an economic and effective treatment for the silicon steel wastewater. According to the Fenton reaction principle, chemical adsorption and chemical flocculation, chemical oxygen demand (COD) and Cr6+ in the wastewater were reduced. The appropriate parameters were as follows: the mol ratio of Fe2+ to H2O2 was 1:2, the mol ratio of Fe2+ (dosage into the wastewater) to Cr6+ (content of the wastewater) was 5.2:1, pH 3-4, temperature 15-35°C. Under these conditions, the removal rate of Cr6+ and CODCr was 99.99% and 98.11% respectively, the Cr6+ and CODCr of the influent reduced from 2959mg/L and 1351mg/L to 0.421mg/L and 25.6mg/L respectively, and the effluent concentration achieved 1-class in "Steel Industrial Water Pollutant Discharge Standard(GB 13456-92)".

TL;DR: In this article, the influence of the height of changin, 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.
Abstract: 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 0.3 mg.L -1 , COD was smaller than 100 mg.L -1 . PH value was close to neutrality, which reach the Second Wastewater Discharge Standard of Country.
