| Abstract: | Chrome tanning wastewater contaminated with grease,fats,proteins and suspended solids could not be recycled directly because these impurities' accumulation would impact on the quality of leather.This study developed a method which can effectively remove the soluble grease,proteins and suspended solids from chrome tanning wastewater with starch-modified flocculant and air flotation.The wastewater,treated and adjusted,can be used directly in the tanning process.As a result,the recycling rate for tanning wastewater can reach 90 percent and the quality of leather is stable. |
