How to make rational and effective use of urban sewage in areas where water resources are scarce is not only a problem of resource regeneration, but also a problem of protecting the environment and keeping the regional economy sustainable. Agricultural sewage irrigation is one of the common ways for the final disposal of sewage. Sewage irrigation can alleviate the shortage of water resources to a certain extent, which is beneficial to the protection of water resources, and can also bring nutrients to crops and increase the yield. However, long-term sewage irrigation will have an impact on groundwater quality, because the source of urban sewage is continuous, and the water demand of crops is seasonal. In the non growing period of crops, sewage is easy to enter the groundwater and cause water pollution. In view of the environmental problems caused by sewage reuse for farmland irrigation, the necessity of reasonable sewage irrigation is explained by analyzing the adverse effects of sewage irrigation on groundwater, farmland soil environment and human health. At the same time, in view of this problem, the research directions that should be strengthened in the future are put forward to provide a theoretical basis for the smooth progress of sewage reclamation.
