  • 摘要: 利用从食材中筛选纯化的特定微生物制成复合菌剂,在自然、厌氧和曝气3种不同的供氧条件下,添加不同比例的菌剂处理生活污水,以COD和氨氮浓度为参考指标,考察菌剂对污水的净化效果,并分析其原因。结果表明:(1)菌剂投加量在0.5‰～1‰时对污水中COD的去除具有明显促进作用,自然、厌氧和曝气3种条件下,COD去除率最大分别提高了8.77%、11.22%和11.11%;(2)氨氮的去除效果受反应条件影响很大,厌氧条件下菌剂对污水中氨氮的去除作用不明显,自然和曝气条件下,菌剂对氨氮去除效果显著,去除率增幅最高分别达到22.6%和52.28%;(3)以0.5‰的菌剂投加量曝气处理2 d,COD和氨氮的去除率可以分别提高11.11%和14.13%,初步研究显示,该菌剂对生活污水具有较好的净化效果。
    Abstract: A complex microbial agent using materials from daily foods and drinks was synthesized. Domestic sewage samples were treated with different ratios of microbial agent under different aerating situations (natural ventilation, anaerobic and aerobic). The removal rates of sewage samples' COD and ammonia concentration were tested. Main results are as follows: 1) Adding 0.5‰ to 1‰ microbial agent to the treating sewage can significantly promote removal rates of COD concentrations, under natural ventilation, anaerobic, or aerobic conditions, and the removal rates of COD increase 8.77%, 11.22% and 11.11%, respectively. 2) Removal rate of ammonia has a significant relationship with the ventilating conditions. The ammonia removal effect under anaerobic conditions seems not distinct, comparatively, under naturally ventilation and aerobic conditions, and the best removal rates of ammonia are 22.6% and 52.28% higher than CK. 3) The best processing condition of treating sewage is under 0.5‰ microbial agent and aerating two days, and the removal rates of COD and ammonia can increase 11.11% and 14.13%, respectively. Preliminary studies show that the new microbial agents could have good treating effects to domestic sewage.
