用有效容积 5L的序批式反应器 (SBR)进行猪粪污水水解出水处理试验。停留时间 (HRT)1 0~ 1 4d。CODCr,BOD5,SS去除率分别为 5 1 2 %~ 81 5 % ,72 4%~ 95 7% ,96 3%~ 97 3% ,但出水中仍残留相当数量的难降解CODCr。SBR对氮有较好的去除效果 ,TN去除率为 74 1% ,特别是对NH4 N的去除效果尤佳 ,去除率达 97%以上。研究表明 :CODCr的降解主要在曝气开始后 30min内完成 ,而NH4 N的去除在整个曝气周期内都在进行 ,在完成CODCr降解后的 90min内去除最快。通过对比试验证明 ,NH4 N的去除不是依靠吹脱作用 ,而是微生物降解的贡献。

The treatment of sulfanilamide waster water by means of SBR(Sequencing Batch Reactor) has been studied. Experimental results indicated that the sulfanilamide waster water could be treated effectively by SBR, the highest rate of removing of COD\-\{Cr\} was 94 5% with the incoming concentrations of 2901~3147 mg/L,and no effect on the under 4500 mg/L of SO\+\{2-\}\-4; It was also showed that the treating efficiency was better with the hydraulic retention time of 32 h and the react period of 8 h.\;

The effects of intermittent aeration cycle, inlet C/N ratio on biological nitrogen removal efficiency and variation tendency of oxidation\|reduction potential (ORP) were studied. The results showed that a half time was needed in a intermittent aeration cycle to achieve sufficient nitrification, and the agitation time should be less than one hour in a cycle. Due to too low C/N ratio in inlet wastewater, the ORP bending\|point didn't appear in denitrification period and the TN removal efficiency was lower than...

The effects of intermittent aeration cycle, inlet C/N ratio on biological nitrogen removal efficiency and variation tendency of oxidation\|reduction potential (ORP) were studied. The results showed that a half time was needed in a intermittent aeration cycle to achieve sufficient nitrification, and the agitation time should be less than one hour in a cycle. Due to too low C/N ratio in inlet wastewater, the ORP bending\|point didn't appear in denitrification period and the TN removal efficiency was lower than 40%, so in this case, ORP was couldn't apply as process control parameter and it was necessary to add external carbon to improve nitrogen removal efficiency.

研究了间歇曝气生物脱氮工艺中 ,曝气周期和污水的 C/N比对脱氮效率的影响 ,以及氧化还原电位 (ORP)变化规律。中试试验结果表明 ,TN污泥负荷为 0 .0 5 kg/(kg MLVSS· d)时 ,间歇曝气系统的硝化反应所需曝气时间与总反应时间比至少要在0 .5以上 ,一周期内搅拌时间不宜超过 1h;反硝化过程中难以找到 ORP曲线突变点 ,因此 ,在低 C/N比污水生物脱氮中 ORP难以作为工程控制参数 ;由于原水的碳氮比太低 ,TN去除率只有 3 5 %~ 40 %左右 ,为提高脱氮效率有必要投入外加碳源。
