Freshwater pond aquaculture water pollution has become an important factor restricting the healthy and sustainable development of the industry. Using engineering facilities to reduce the discharge of aquaculture feces, leftover feed  and tail water is the development trend for pond industry. At present, freshwater pond aquaculture emission reduction projects mainly include: constructed wetland based pond recirculation  culture-system, "three ponds and two dams" water purification system, "container + ecological pond" aquaculture system, green and efficient captive system, plant floating bed and pond integrated aquaculture system, tank-pond circulating aquaculture system and multi-trophic level integrated aquaculture system. In this paper, these 7 popular engineering facilities were reviewed and analyzed from the perspectives of aquaculture system engineering construction and operation. With these facilities, some of the nutrients were reused to certain extent by collecting sewage, discharging sewage, precipitation, microbial degradation and plant absorption. However, limited by technical defects and industrial foundation, the current popularization and utilization rate of the facilities for pond aquaculture and emission reduction is not high. This paper suggests that, in future, we should strengthen the basic research on nitrogen and phosphorus circulation in pond, actively develop efficient treatment facilities for aquaculture nitrogen and phosphorus pollutants, and improve the industrial chain of pond aquaculture emission reduction projects. This study will provide references for the sustainable and healthy freshwater pond aquaculture development in China.
