摘要
EM经三种培养基富集培养后,用其培养液对微污染水进行净化处理。结果表明:三种培养液在曝气或静置的运行条件下,对微污染水中的COD和氨氮有稳定良好的去除效果,其去除率分别为50%和85%;对磷酸盐的去除随运行条件的不同而不同,曝气条件下比静置条件要好,其去除率也都在60%以上。试验证明:EM培养液对微污染水有良好的净化能力。
Minor-polluted water was purified by enriched solution after successful enrichment of EM. The results showed that in either aerobic or static condition, the removal rates of COD and NH3-N degraded by three different solutions were more than 50% and 85%, respectively. The removal rate of PO4^3- changed with the operation condition.The removal rate of PO4^3- in aerobic condition was better than that in static condition, being more than 60% .The experiments proved that the EM solution had a good effect on purifying the minor-polluted water.
