Laboratory Research of Distributed Domestic Sewage by Constructed Wetland Treatment Process

Abstract:

In order to solve practical problems of rural sewage treatment, constructed wetland waste water treatment system is chose to simulate, analyze and evaluate in laboratory. Sand and gravel, granular activated carbons were used as the filter media in the constructed wetland. Experimental results show that the removal rate of filter for the water treatment increases with the rise of the hydraulic retention time and the rise of the temperature. It can be satisfied with the treatment effect at an ambient temperature of 15°C, maintained for 4 days or more hydraulic retention time.
