Domestication and cultivation method for denitrifying biofloc seed

The invention relates to a domestication and cultivation method for a denitrifying biofloc seed. PH, total alkalinity and total hardness of a water body are regulated to a proper range, then a biological denitrifying agent, a biofloc culture medium, potassium nitrate, potassium chloride and ammonium chloride are added to the water body, and good bacteria containing ammonifiers, nitrite bacteria, nitrifying bacteria, denitrifying bacteria and the like are cultivated step by step. The water body can be cleaned, a system can be stabilized, disinfection and killing drugs are not used in the wholeculture process, and green cultivation and zero-pollution discharge are realized truly. 本发明涉及种脱氮型生物絮团种驯化培育方法，先将水体调整pH值和总碱度、总硬度到合适范围，再向水体中加入生物脱氮剂和生物絮团培养基以及硝酸钾、氯化钾、氯化铵，逐步培育出包含氨化细菌、亚硝化细菌、硝化细菌及反硝化细菌等有益菌群。能够洁净水体、稳定系统，养殖全程不使用消杀药物，从而真正实现绿色养殖、零污染排放。
