【摘要】 本试验主要研究了在低温条件下,生物脱氮除磷倒置A2/O工艺小试系统处理效果随温度的变化情况,并通过试验确定了所研究水质硝化效果变差的临界温度。试验结果表明:当进水温度下降到15～7℃时,小试的硝化及除磷效果会随之明显下降。该水质条件下生物硝化效果变差的临界水温为13℃。更多还原

【Abstract】 The effect of temperature on biological nitrogen and phosphorus removal by reversed A2/O process system was studied under the condition of low temperature to seek for the critical temperature to make the nitrification effect in the water studied get poor.It was shown that,when the influent temperature dropped to 15～7℃,the performance of nitrification and phosphorus removal lowered obviously.The lab test showed that the critical temperature to make the biological nitrification effect get poor was 13℃.更多还原
