New Concept Design of Modified DEWATS System for Wastewater Treatment with both Horizontal Subsurface Constructed Wetland and Aquatic Plants Pond System in Military Barracks

Abstract:

Taking military barracks wastewater treatment as an example, this paper presents a new concept design of a modified DEWATS system with both the horizontal subsurface constructed wetland and aquatic plants pond. Results show that this process in treating the military barracks area wastewater have many advantages such as low operation cost, simple operation and maintenance, and the effluent could meet the urban wastewater treatment plant pollutant discharge standard "(GB18919-2002) for first level Class A. It is suitable for the military barracks which have difficulty to be connected to centralized sewerage treatment system. At the same time, it can effectively improve the internal and surrounding water environment around the military barracks. This is a flexible wastewater treatment technology and can be replicated and applied for decentralized wastewater treatment.
