Abstract:

The project on the treatment of wastewater from bearing production is introduced. Its principal technologies are iron-carbon coupling Fenton advanced oxidation. Technologies,such as the regulation of oil removal,dissolved air floatation,hydrolytic acidification,iron carbon coupling Fenton reagent oxidation,flocculation and precipitation,charcoal canister adsorption. etc. have been used. After the treatment,the removing rates of COD,SS,petroleum substances,TP,anionic surfactants,total chromium,and total nickel of the effluent are 95.7%,98.6%,95.8%,97.2%,90.3%,92.7%and,93.3%,respectively,meeting the requirements for the first level discharge standard,specified in the Integrated Wastewater Discharge Standard(GB 8978-1996). The project has advantages as follows:less investment,small coverage of area,stable operation,strong anti-shock loading capacity,etc.

Key words: bearing wastewater, advanced oxidation, dissolved air flotation, wastewater treatment
