Water and Wastewater Engineering Final Class ProjectTitle：Applications of municipal wastewater treatment in livesCollege _____ C 。 E __________ Major ___ _ WWE __________ Class __ __ _ ______ Number_____ ____ Name____ _____ Data_____________________Applications of municipal wastewater treatment in livesAbstract：This article describes the following sections：sequential combination of photocatalytic oxidation with constructed wetlands is the study and the experimental evaluation of an alternative and innovative wastewater treatment system， which combines the action of photocatalytic oxidation with the surface flow constructed wetlands.A new contact oxidation filtration separation integrated bioreactor was used to treat municipal wastewater 。 the synthetic polymers normally used in the coagulation—flocculation treatment of waste water requires sustainable alternatives。Keywords:bioreactor;coagulation;flocculation；photocatalytic oxidation；Combination of photocatalytic oxidation with constructed wetlands Wastewater treatment systems have been designed to minimize the environmental impacts of discharging untreated wastewater.Different options for wastewater treatment have different performance characteristics and also different direct impacts on the environment. During the last decades centralized conventional wastewater treatment systems were typically provided to large cities and secondary towns 。 They involve large capital investments and operating costs, resulting in systems which are considered as not proper solutions for small villages that cannot afford such expensive treatment facilities.In addition， low water use rates and several operational problems have been encountered with such systems in rural and especially in touristic areas where...
