污泥有機負荷對TP去除的影響
污泥負荷是指單位質(zhì)量的活性污泥,在單位時間內(nèi)所能承受的污染物的量。下面是小編收集整理的污泥有機負荷對TP去除的影響,希望大家喜歡。
摘要: 通過改變?nèi)斯ず铣晌鬯臐舛、流量和污泥濃度,探討有機污泥負荷對無回流間隙曝氣系統(tǒng)(Non-Backflow Intermittent Aeration System,縮寫為NBIAS)脫氮除磷和有機物去除效果的影響。試驗表明,在通過改變進水流量或濃度而引起污泥負荷變化的條件下,當進水CODcr為300~400 mg/L,流量為0.5 L/h,污泥濃度為2.0 g/L(對應污泥負荷為0.3 g CODcr/(g MLSS*d))左右時,系統(tǒng)去除有機物、氮、磷總體效果最佳。
Abstract: The effect of organic sludge loading on the removal of nitrogen, phosphorus and organic matter in NBIAS was discussed by changing the concentration and flow rate of the synthetic wastewater and the MLSS. The tests showed that under the operation conditions, the system gains the most optimal efficiency of the CODcr, nitrogen and phosphorus removal. The operation conditions are: the influent CODcr——300~400 mg/L, flow rate——0.5 L/h, sludge concentration 2.0 g/L (organic sludge loading 0.3 g CODcr/(g MLSS*d)).
