摘要:
以东北地区某城市污水厂作为研究对象，对污水处理工艺中磷组分的时空变化规律展开了分析，并进行了单一和复合混凝剂除磷实验，同时对比了混凝剂对不同形态磷的去除效果。结果表明，夏季进水中总磷（TP）较高，可达5.35 mg/L，而春、冬季进水 TP平均约为1.91 mg/L。进水中的颗粒态磷（PP）受季节影响显著，春季PP约占TP的39.1%，夏、冬季PP约占TP的60%。污水经过二沉池处理后，TP降至0.44~0.68 mg/L，经生化处理后PP得到有效降解，在后续深度处理工艺中，可有针对性地投加药剂，以强化除磷效果。混凝实验结果表明，FeCl3除磷效果最佳，对TP的去除率可达93.9%；当聚合氯化铝（PAC）与聚合硫酸铁（PFS）的质量投加比为1∶2时，除磷效果与单独投加PFS相似；当Al2（SO4）3与FeSO4的质量投加比为1∶2时，除磷效果优于单独投加FeSO4或Al2（SO4）3的，且在三组混凝剂复合实验中除磷效果最好。
Abstract:
This study investigated the spatial-temporal variation characteristics of phosphorus components during the wastewater treatment process of a wastewater treatment plant in a city in Northeast China. Laboratory-scale experiments were conducted to evaluate phosphorus removal efficiency using both single and composite coagulants, with comparative analysis performed on the removal performance of different phosphorus forms under identical conditions. The total phosphorus (TP) in the influent during summer was relatively high, reaching up to 5.35 mg/L, whereas the average TP in spring and winter was approximately 1.91 mg/L. The concentration of particulate phosphorus (PP) in the influent exhibited notable seasonal variation. In spring, PP constituted approximately 39.1% of TP, whereas it accounted for around 60% of TP during summer and winter. Following secondary sedimentation, the TP decreased to 0.44-0.68 mg/L. After biochemical treatment, PP was effectively converted or degraded. In the subsequent advanced treatment stage, specific chemical agents were introduced to further enhance phosphorus removal efficiency. FeCl3 exhibited the highest phosphorus removal efficiency, achieving a TP removal efficiency of up to 93.9%. When the mass dosage ratio of polyaluminium chloride (PAC) to polyferric sulfate (PFS) was 1∶2, phosphorus removal performance was comparable to that of PFS used individually. When the mass dosage ratio of Al2(SO4)3 to FeSO4 was 1∶2, the phosphorus removal performancewas superior to that achieved by using FeSO4 or Al2(SO4)3 individually, and it exhibited the best phosphorus removal efficiency among the three types of composite coagulant experiments.
