卵囊藻耦合硅藻处理养鳗尾水的研究
Study on the treatment of eel farming tailwater by Oocystis coupled with diatom
摘要
Abstract
This study aims to construct a mixed culture system of Oocystis and diation Phaeodactylum tricornutum,and evaluate its potential for removing nitrogen and phosphorus as well as treating antibiotic-containing aquaculture tailwater.The nitrogen and phosphorus removal capacity was evaluated by monitoring water quality parameters(NH+4-N,NO-3-N,NO-2-N,PO3-4-P,and CDO),assessing carbon capture capacity by monitoring microalgae growth,and exploring the stress response of microalgae to antibiotics by monitoring the chlorophyll a content and antioxidant enzyme activity.Results showed that the mixed algae system achieved a 100%removal rate of ammonia nitrogen.The concentrations after treatment of nitrate nitrogen,nitrite nitrogen,total nitrogen,total phosphorus,and chemical oxygen demand were 13.50±1.17 mg/L,0.20±0.01 mg/L,15.09±1.14 mg/L,0.71±0.03 mg/L,and 31.57±2.51 mg/L,respectively,with corresponding removal efficiencies of 86.03%,67.33%,86.13%,94.87%,and 50.60%.The concentration of CIP was 4.52±0.45 mg/L,with a removal efficiency of 90.95%.The carbon capture rate(CO2-equivalent)of Oocystis reached its peak with 0.47 g/(L·d)during the logarithmic growth phase.Microalgae enhanced their antioxidant capacity by increasing the activities of CAT and POD.This study indicates that the mixed algae culture system has a positive effect on nitrogen and phosphorus removal,as well as ciprofloxacin removal.It provides new perspectives for the resource utilization of aquaculture tailwater and important practical application.关键词
