竹炭-微生物联合法对沼液中氨氮的去除
Ammonia nitrogen removal from biogas slurry by bamboo charcoal-microbe
摘要
Abstract
An experiment was carried out to establish the optimal operating conditions for a combined treatment of bamboo charcoal and microbes(BCM) to remove ammonia nitrogen from biogas slurry.The treatment showed a high removal efficiency when the bamboo charcoal was applied at the rate of 30 g/L,inoculated bacterium solution was at the concentration of 3%,pH value between 7.0~8.0,DO at the value of 2 mg/L,and HRT of 48 h.The removal dynamics could be described as a first order equation(i.e.C=272.56e-0.0148).The synergistic reaction between bamboo charcoal adsorption and microbial degradation(48.45%) could be one major reason that BCM showed a great removal efficiency when compared with the separated treatment by bamboo-charcoal or microbes.关键词
