| 摘 要： | 采用竹炭-微生物联合法,考察了竹炭用量、菌液用量、进水氨氮浓度、pH、DO、HRT等因素对氨氮废水处理效果的影响;同时采用对比实验,初步探讨了竹炭-微生物联合法处理沼液的作用机理。结果表明,竹炭-微生物法去除沼液氨氮的最优条件推荐为:竹炭用量30 g/L,微生物活性液用量3%,pH 7.0～8.0,DO为2 mg/L,HRT为48 h。竹炭-微生物法对沼液氨氮的去除过程可用一级反应动力学模型C=272.56e-0.0148描述,其去除效果来源于竹炭吸附和生物降解的协同作用,协同程度为48.45%。 |

| 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. |
