A 96 m3 UASB reactor was operated for 2.5 years under different conditions to assess the feasibility of treating strong sewage
(CODtot = 1531 mg/l) at ambient temperatures with averages of 18 and 25 \1C for winter and summer respectively.During the first
year,the reactor was operated as a two-stage system at OLRs in the range of 3.6–5.0 kg COD/m3d for the first stage and 2.9–4.6 kg
COD/m3d for the second stage.The results of the first stage showed average removals of 51% and 60% for CODtot and CODss
respectively without significant effect of temperature.The second stage reactor was unstable.The temperature affected sludge stabilization.
During the second year,the first stage was operated as a single-stage UASB reactor at half of the previous loading rates.
The results showed an average removal efficiency of 62% for CODtot during summer,while it dropped to 51% during wintertime.
However,the effluent suspended solids were stabilized with VSS/TSS ratio around 0.50 all over the year.The sludge in the singlestage
reactor was well-stabilized and exerted an excellent settlability.During the last three months of research,sludge was discharged
regularly from the single-stage UASB reactor.The results showed no significant improvement in the performance in terms of
CODtot.Based on the results of the experiment,a single-stage UASB reactor operated at relatively long HRT is preferred above
two-stage system at the Jordanian conditions.

1 96立方米UASB反应器操作为2.5年,根据不同情况,以评估治疗的可行性强污水
（ codtot = 1531毫克/升） ,在环境温度平均每18至25 C的冬季和夏季.在第一
今年,该反应堆是经营作为一个两阶段系统olrs在一系列3.6-5.0公斤cod/m3d为第一阶段,2月9日至4月6日公斤
cod/m3d为第二阶段.在第一阶段的结果显示,平均清除量的51 ％和60 ％ ,为codtot和codss
分别为无显着温度的影响.第二阶段反应堆是不稳定的.温度影响污泥稳定.
在第二年,第一阶段是经营作为一个单级UASB反应器在半以前装载率.
结果表明,平均去除率为62 ％ ,为codtot是在夏季,而下降到51 ％ ,在冬季.
不过,出水悬浮固体量分别稳定的VSS /可溶性固形物比率约为0.50 ,所有超过一年.污泥在单阶段
