微生物菌剂净化鱼塘养殖污水的研究进展

Research progress of microbial agents for purification of fish pond culture effluent

综述了利用微生物菌剂来净化鱼塘养殖污水的研究进展,介绍了鱼塘养殖污水中常见污染物质及其净化机制,分析了影响鱼塘养殖污水净化效果维持能力的主要因素。

Aquaculture brings rich aquatic products,but also produces a large amount of aquaculture wastewater.The treatment of aquaculture wastewater has always been a difficult problem in aquaculture.In recent years,microbial agents have been widely used in aquaculture due to their high efficiency,environmental protection and economy.Microbial agents use the metabolic activities of microorganisms to degrade organic matter,nitrogen and phosphorus in water,reduce the concentration of harmful substances such as ammonia nitrogen and nitrite in water,and produce a large number of beneficial microorganisms to improve the microbial diversity and stability of microbial community structure in water,so as to achieve the purpose of purifying water,repairing ecological environment and preventing and treating diseases.The research progress of using microbial agents to purify fishpond aquaculture wastewater was reviewed.The common pollutants in fishpond aquaculture wastewater and their purification mechanisms were introduced.The main factors affecting the maintenance ability of fishpond aquaculture wastewater purification were analyzed.
