Design Key Points of Ozone Treatment System in WWTPs

The process of ozone oxidation has a very wide range of application in WWTPs with high proportion of industrial wastewater and reclaimed water plants with high effluent quality requirements, but ozone treatment system has obvious particularity compared with conventional wastewater treatment process. For the purpose of applying the ozone treatment systems efficiently £¬ economically and safely, based on the principle of ozone generation£¬ the normal operating requirements of generator£¬ the physical and chemical properties of ozone and the ozone process objectives and their corresponding empirical process parameters, combined with relevant engineering design, construction and operation cases, this paper discussed the process design, equipment selection and construction key points of gas source system, ozone generation system, ozone delivery system, ozone dosing and reaction system which were easily neglected. In addition, the fire protection and explosionª²proof design key points and safety instrument configuration of ozone treatment process were summarized.
