罗非鱼加工废水微生物除臭处理的研究

Study on microbial deodorization treatment of tilapia processing wastewater

摘要: 以米曲霉、枯草芽孢杆菌、生物除臭剂为供试菌,对海南罗非鱼加工废水进行了生物除臭研究。考察了除臭过程中废水蛋白质残留量、挥发性盐基氮和pH的变化。结果表明,废水中加入3%葡萄糖后,用枯草芽孢杆菌处理的除臭效果最好。废水中蛋白质的含量从对照的4.5g/100mL降低到0.8g/100mL;挥发性盐基氮含量从对照的0.91g/100mL下降到0.04g/100mL,下降率为95%。本文为罗非鱼加工废水的处理和资源化,探讨出一种新的途径。

Abstract: Hainan tilapia processing wastewater was treated with Aspergillus oryzae, Bacillus subtilis and biological deodorant. The experiment process had investigated the protein residues, the content of TVB -N and the change of pH value in the deodorization process. Results showed that, the wastewater’s odor treated by Bacillus subtilis with adding 3% of glucose was the least, the content of protein in wastewater reduced from 4.5g/100mL of control group to 0.8g/100mL, the content of TVB-N reduced from 0.91g/100mL of control group to 0.04g/100mL after treatment with the decline rate of 95% . A new way for the tilapia processing waster treatment and resource was explored.
