【摘要】 在10~22℃范围内,通过实验考察了温度对腐殖土间歇式活性污泥处理(SBR)系统的运行特性的影响。实验结果表明,降低温度对SBR腐殖活性污泥系统去除COD影响不大,当温度降至10℃时,COD去除率仍可达到80%以上;在22~14℃范围内,SBR腐殖活性污泥系统对NH4+-N和TN的去除影响不大,温度降至10℃时,NH4+-N和TN去除率则大幅降低,分别降至57%和52%;降低温度对反应器的TP去除率、污泥沉降性和脱水性的影响不大。

【Abstract】 The effect of temperature(10~22 ℃) on SBR system with humic soil was investigated.The results show that temperature reduction has no obvious effect on COD removal in SBR filled with humic soil,however,the COD removal rate could reach more than 80% even at 10 ℃.It is not distinct change on the NH+4-N and TN removal in temperature range from 22 ℃ to 14 ℃.The removal rates of NH+4-N and TN dramatically reduced at 10 ℃,57 % and 52% separately.Temperature reduction has little effect on TP removal rate and the characteristics of sludge settling and dewaterbility.
