利用厌氧生物活性炭实现厌氧生物滤池快速启动
|
摘要
厌氧生物滤池通常采用接种活性污泥的方式加速启动过程,但该方法的接种生物量较低且接种的微生物要经历从好氧到厌氧、悬浮生长到附着生长的演变过程。针对上述问题,提出接种厌氧生物活性炭加速厌氧生物滤池启动的解决方案。设计不同厌氧生物活性炭接种比例(0、25%、50%和100%)的厌氧生物滤池启动试验装置,装填比为25%、50%和100%的厌氧生物滤池分别在16、13和8 d后完成启动,而未装填厌氧生物活性炭的厌氧滤池启动非常缓慢。表明接种厌氧生物活性炭可实现厌氧生物滤池的快速启动。厌氧生物活性炭可在沥干密封后采用常温运输保存,运输保存期不超过3 d基本不影响接种效果,因此该技术方案具有重要的应用价值。
Anaerobic biofilters mostly inoculate activated sludge to accelerate the start-up process.However,this method has a low inoculation mass and the microorganisms inoculated will undergo an evolution from aerobic type to anaerobic type,suspended growth type to attached growth type. In order to solve the above problems,a solution of inoculating anaerobic microorganisms by using anaerobic biological activated carbon to accelerate the start-up process of the anaerobic biofilter is proposed. Anaerobic biofilter devices with different anaerobic biological activated carbon filling ratios( 0,25%,50% and100%) were designed. The results showed that the anaerobic biofilters with filling ratio of 25%,50%and 100% completed start-up process after 16 days,13 days and 8 days,respectively. However,anaerobic biofilter without filling anaerobic biological activated carbon started very slowly. It proved that inoculation of anaerobic biological activated carbon could achieve rapid start-up of anaerobic biofilter. The anaerobic biological activated carbon could be transported and stored at room temperature after drained and sealed. It did not influence the effect of inoculation basically when the transportation and storage period was no more than three days,so the solution had important application value.
