Fe3+、PO43-在煤气化废水处理中的应用
Application of Fe3+ and PO43- on Treatment of Coal Gasification Wastewater
【摘要】 针对煤气化废水的特点,通过投加Fe3+、PO43-的方法来强化多阶段水解-好氧工艺处理煤气化废水的能力,不加Fe3+、PO43-时,CODcr总去除率为78 88%,出水CODcr仍高达931mg/l,当投加Fe3+、PO43-后,出水CODcr降到245mg/l,去除率达到93 93%。
【Abstract】 The capability of treating coal gasification wastewater using the hydrolysis and aerobic process through adding Fe3+ and PO43 is strengthened in accordance with the property of coal gasification wastewater. The total removal rate of CODcr is 78.88% without adding Fe3+ and PO43, the concentration of CODcr of the wastewater is 931mg/l. The concentration of CODcr of the wastewater is 245mg/l, and the removal rate reaches 93.93% when adding Fe3+ and PO43.
