Nitrogen and phosphorus zero emission system

The utility model provides a nitrogen and phosphorus zero discharge system. The nitrogen and phosphorus zero discharge system comprises a wastewater collection tank, a reaction system, a sedimentation tank, a sand filtration device, a carbon filtration device, an ultrafiltration device, a reverse osmosis system and an evaporation device which are sequentially connected through pipelines. According to the nitrogen and phosphorus zero discharge system provided by the utility model, ammonia nitrogen ions in water are removed by forming a breakpoint chlorination reaction in a reaction system, so that the quality of membrane produced water can be improved; the residual phosphorus is subjected to wastewater concentration in a membrane concentration form, so that the evaporation investment and operation cost can be reduced; in addition, zero discharge of wastewater can be really realized in a wastewater evaporation mode. 本实用新型提供一种氮磷零排放系统，包括经管道顺次连接的废水收集池、反应系统、沉淀池、砂滤装置、碳滤装置、超滤装置、反渗透系统和蒸发装置。本实用新型提供一种氮磷零排放系统，通过反应系统中形成折点
