| 摘 要： | 分别采用硫酸铝和改性硅藻土对低碳源城市污水进行化学除磷试验,并对其剂量、除磷效果及成本进行比较分析.研究结果表明:TP=3.5 mg/L时,投加60 mg/L的硫酸铝可使出水TP＜1.0 mg/L,而改性硅藻土只需30 mg/L,且效果更稳定,成本也可节省10％；改性硅藻土的投加量为50 mg/L时,出水TP＜0.5 ...

| Abstract: | Aluminum sulfate and modified diatomite have been used respectively for carrying through the chemical dephosphorization from low-carbon municipal sewage.And,its dosages,dephosphorization effectiveness and operational costs have been compared and analyzed.The results show that when TP=3.5 mg/L,and Al2(SO4)3 dosage is 60 mg/L,the effluent TP is less than 1.0 mg/L.But,more stable effectiveness can be obtained when the dosage of modified diatomite is only 30 mg/L.Furthermore,10% of operational cost can be saved... |
