簡介 | In PCB wastewater treatment, TN concentration is about 80-100mg/L while the COD is only about 300 mg/L. In traditional A2O process, the nitrogen removal will consume some COD as carbon source. However, the carbon source from the wastewater is not enough for the TN removal therefore additional carbon source is needed which increase the treatment cost of the wastewater treatment plant. While the MBBR integrated with A2O process, SCBNR can reduce the carbon usage during the denitrification. With the new system in place, the pollutants including COD, Ammonia and TN in PCB wastewater produced on production line can be reduced to meet the discharge standard. 在該應用中,移動床生物反應器(MBBR)工藝將結合到A2O的過程中,以增強氮的去除。MBBR由高密度聚乙烯或聚丙烯製成,具有較大的面積以供生物膜依附,為SCBNR提供合適的條件。 在PCB污水處理中,TN濃度約為80-100mg/L,而COD僅約300mg/L。 在傳統的A2O工藝中,脫氮將消耗COD以作為碳源。然而,來自污水的碳源不足以去除TN,因此需要額外的碳源,這增加了污水處理廠的處理成本。雖然MBBR與A2O工藝互相結合,但SCBNR可以減少反硝化過程中的碳使用量。 隨著新系統的發展,這可以減少在生產線中所產生的COD,氨和TN等污染物,以達到排放標準。 | ||
