【摘要】 水葫芦对不同浓度畜禽废水的净化试验表明,水葫芦对中高浓度的畜禽废水有很强的净化能力,在25d内对有机物(以化学需氧量CODcr表示)的去除率在60%~88%之间;对总氮(TN)的去除率在50%~90%之间,对总磷(TP)去除率介于50%~60%之间。水葫芦对畜禽废水中CODcr、TN、TP的净化速率符合一级动力学方程,其中对CODcr、TN净化效率随废水浓度的升高而降低,而水葫芦对TP的净化效率则受畜禽废水起始浓度的影响较小。更多还原

【Abstract】 The experiments in the purification ability of water hyacinth for waste water from livestock showed that the water hyacinth had significant purification ability.Within 25 days,the removal rates of organic matter,TN and TP were 60%～88%,50%～90% and 50%～60% respectively.The purification velocity of water hyacinth for middle-high concentration waste water from livestock was in accord with the first order reaction kinetics,and the purification effect on CODcr and TN decreased with the concentration of waste water increasing.Meanwhile,the purification effect on TP was less influenced by initial concentration of waste water.更多还原
