Abstract. Fresh water is a valuable nonrenewable resource and plays an important role of maintaining economic and social development. Sewage irrigation was taken a supplementary way to relieve water resource shortage in some areas (such as North China). With extensive implementation of sewage irrigation, serious pollution and destruction for farmland have gradually become a heated issue, impeding basic industries sustainable development in the near future. Here in this paper, some soil physical properties (soil bulk density, soil resistance to penetration and field capacity) and chemical properties (pH, soil organic matter, nitrogen, phosphorous, potassium, heavy metal and organic pollutants contents) and biological characteristics (soil microorganisms and enzyme activities) of farmland affected by sewage irrigation were systematically reviewed on the base of the current utilization status of China and some valuable suggestions were put forward to the future development prospects. This review will be beneficial for promoting healthy development of sewage irrigation and providing theoretical support for reclamation and high efficiency of effluents in China.
