【摘要】 天津经济技术开发区污水处理厂采用先进的DATIAT工艺,针对该污水处理厂冬季和夏季的实际运行效果分别进行研究、比较,并就DAT池和IAT池对有机物的去除效果进行分析。研究发现,污水处理厂实际运行中,对BOD5的去除效果十分彻底,对CODCr的去除效果一般,但都能够保证出水达标。DATIAT工艺系统的抗冲击负荷能力较强污水处理厂DAT池过高的BOD5去除率对后续的脱氮除磷效果会产生不利的影响。更多还原

【Abstract】 DAT-IAT process is used in a sewage treatment plant of Tianjin Economic and Technical Development Zone.The operating effect in both summer and winter was compared and the removal effect of organic matter in both DAT tank and IAT tank was analysed.The discovery shows that the removal effect of COD Cr and BOD₅ was almost the same in summer and winter.The removal effect of BOD₅ was much more complete.The removal rate of BOD₅ in DAT tank would make an unfavorable influence towards removing phosphorus and nitrogen.更多还原
