摘要
升流式厌氧污泥床(UASB)的优点是处理能力大、处理效率高、运行性能稳定。该试验研究是在常温下,在UASB反应器中接种猪粪,经培养驯化后处理硝化棉废水,控制进水pH值在6.5～7.5之间,在尚未进行任何预处理的情况下,经过44天的运行,启动基本完成。在此后的负荷运行中,容积负荷从0.63 kg CODcr/(m3.d)增加到1.5 kg CODcr/(m3.d),CODcr的去除率保持在40%以上,最高达到了67.9%。
Upflow anaerobic sludge bed （UASB） has the advantages of large capacity, high treatment efficiency and stable operation performance. The experimental study is conducted at room temperature to process pig manure in UASB reactor after the pH value of influent nitrocellulose wastewater were control at between 6. 5 and 7.5. Without any pretreatment, start phase has ba- sically completed after 44 days of operation. In the load operation, volume load increased from 0. 63 kg CODer/（ m3 d） to 1.5 kg CODcr/（m3 d）, and the CODor removal rate was above 40% with the highest reaching 67.9%.
