Experimental Study on Hybrid Wastewater Treatment Using High Ozone Concentration and Microorganisms for Restaurant Industry

摘要

Experiments were carried out using the liquid-waste treatment system which combines the ozone system using micro bubbles with a private sewerage system to treat restaurant kitchen wastewater．When the system works at its best the amount of generated scum is decreased about 75％ compared with the existing system. The maintenance cost is also decreased about 15％．This system is able to increase the deodorizing capability by increasing the amount of ozone. However, optimum amount of ozone does exist, as the oxidation of fat and oil accelerates the production of formaldehydes．
