水产养殖存在的严重问题之一是残饵和排泄物引起的水质败坏，导致养殖生物发病以至死亡。光合细菌技术是应用生态学原理形成的生物技术，将天然水体自净中发挥重要作用的光合细菌繁殖后引进养殖水体，达到净化目的。光合细菌在厌气条件下利用水中的有机质及其分解产物氨氮、硫
One of the serious problems with aquaculture is the deterioration of the water quality caused by bait and excrement, which leads to the death of the cultured organisms. Photosynthetic bacteria technology is the application of ecological principles of biological technology formed by the natural water self-purification of photosynthetic bacteria play an important role in the breeding water after the introduction of breeding to achieve the purpose of purification. Photosynthetic bacteria in the anaerobic conditions using organic matter in water and its decomposition products ammonia nitrogen, sulfur
