摘要
采用活性污泥、光合细菌和小球藻组成的菌藻共生序批式生物膜反应器(SBBR)对猪场沼液进行了净化处理,研究了HRT和光照度等因素对污染物去除效果的影响。结果表明,优化HRT为2 d、光照度为5 klx。系统运行稳定后,COD、NH_4^+-N、TN和TP的去除率分别为92.16%±0.82%、97.98%±0.53%、87.95%±0.55%和84.25%±0.45%,出水COD和NH_4^+-N、TN、TP的质量浓度分别为(143.3±15.0)mg/L和(14.24±3.74)、(97.48±4.45)、(5.20±0.15)mg/L。该系统稳定性好,能有效地去除沼液中的污染物,可用于猪场沼液净化。
The algae-bacteria symbiotic SBBR reactor composed of activated sludge, photo- synthetic bacteria and chlorella, which was used to purified the biogas slurry from pig farm. The effects of HRT and light intensity on pollutants removal efficiency were studied. The results showed that, the optimum HRT and the optimum light intensity was 2 days and 5 klx respectively. When the system was running stable, the removal rate of COD, NH4＋-N, TN and TP was 92.16%±0.82%, 97.98%±0.53%, 87.95%±0.55% and 84.25%±0.45% respectively. The COD, and mass concentrations ofNH4＋-N, TN, TP in the effluent were （143.3± 15.0） mg/L, and （14.24±3.74） mg/L, （97.48±4.45） mg/L, （5.20±0.15） mg/L respectively, The system had good stability and it could effectively remove the pollutants in biogas slurry, which could be used to purify biogas slurry from pig farm
