| Gas floatation process is a very effective method to deal with oily waste water. Gas floatation process to remove oil in wastewater,is to make exiguous emulsified oil droplets in wastewater to adhere to the air bubbles,which generated by bringing air to wastewater,and then ,the oil droplets float up to water surface with them.So that,the deposed oil in wastewater is reclaimed.Oil removal efficiency is chiefly decided by oil droplet size,bubble size and the chemical properties of the oil-drop surface.The principle of molecule design of floatation agent and its types are studied in this paper by analysing the chemical properties of suspending substances in wastewater and the formula of Stokes. Furthermore, the current research of floatation agent is also discussed.Then we carry on ternary emulsion polymerization with monomer AM,monomer DMC and monomer MMA to abtain product FJ by consulting a large number of domestic and international documents.And through the infrared spectrum,the composition and structure of the product have been defined. Besides,this text has probed into reaction temperature,response time,the weight rate of the three monomers,which causes the influence to the emulsion polymerization,such as dosage,etc. of initiator.Finally,FJ is used in gas floatation process in laboratory,which proves FJ there having good oil removal efficiency.lt reaches even exceeds the performance and competence of domestic similar product. |
