Application of constructed wetlands in sewage treatment in small cities in China

Abstract

Abstract: The water quality and the technological requirement of sewage treatment in small cities were analyzed.Being a new wastewater treatment technology especoally suitable for China small cities, the constructed wetlands have the advantages of low investment, high quality effluent, less dissipation of energy, simple performance and cheap operation cost. The study of this technology should be strengthened.

Key words: Northern agro-pasture ecotone, Land use type, Soil nutrient, Soil erosion
