水产养殖水体污染及微生物修复的研究

Research on Water Pollution and Microbial Remediation of Aquaculture

养殖水体常由于饵料残留、药物及抗生素的过度使用、池底淤泥等原因导致水质逐渐恶化,加之工业污水及生活污水的排放,使水体中氨氮、亚硝酸盐、硫化物、COD、BOD等指标严重超标。微生物修复技术绿色环保,成本低,能够消除污染物,净化水质,可以抑制水中有害微生物的繁殖,提高水产动物的免疫力。该文介绍我国水产养殖水体污染状况及微生物修复在水产环境中的研究进展。

Food residues,excessive use of drugs and antibiotics,bottom sludge can cause gradual deterioration of water quality,coupled with industrial effluents and life sewage discharge, so that ammonia nitrogen, nitrite, sulphide, COD, BOD and other indicators are exceeded seriously.The technology of microbial remed^ation is green,low cost,not only eliminates pollutants,purifies water,but also inhibits the reproduction of harmful microorganisms in water,improves the immunity of aquatic animals. The paper introduced the water pollution status of aquacuhure in our country and the research progress on microbial remediation.
