摘要

针对含磷废水需在40 s内进行应急处理以避免带来的环境风险问题，采用过氧化氢-盐酸（H

-HCl）活化微米零价铁（mZVI）制备活性微米铁，并与氧化钙（CaO）形成复合体系，实现了40 s内将废水磷的质量浓度降至低于0.2 mg/L、pH值维持在6~9（地表Ⅲ类水标准）。首先，分别单独投加CaO和活性微米铁进行实验；然后，采用活性微米铁/CaO复合体系处理含磷废水，并研究其除磷机制；最后，进行稳定性实验，并进一步在模拟现场条件下开展连续流实验。实验结果表明：将CaO和活性微米铁复合投加，可在40 s内使含磷废水达到地表Ⅲ类水标准；采用H

-HCl加速mZVI的氧化腐蚀，使得活性微米铁具有较多的活性吸附位点Fe

，从而能够有效吸附磷酸盐，并形成以Fe

（PO

）

和FePO

为主的Fe-P化合物；通过化学沉淀作用，CaO与磷酸盐生成以Ca

（PO

）

（OH）为主的Ca-P化合物，实现了化学沉淀与吸附的有机结合；在监测周期长达28 d的稳定性实验及连续流实验中，经活性微米铁/CaO处理后的废水磷的质量浓度和pH值均保持稳定，并可实现在40 s内达到地表Ⅲ类水标准。该研究结果可为含磷废水的应急处理提供理论依据。

Abstract

In order to address the urgent need for the treatment of phosphorus-containing wastewater within 40 seconds to avoid environmental risks

an active micron zero-valent iron (mZVI) is prepared by hydrogen peroxide-hydrochloric acid (H

-HCl) activation and combined with calcium oxide (CaO) to form a composite system. This system reduces the phosphorus concentration in wastewater to below 0.2 mg/L and maintains the pH value between 6 and 9 (surface water class Ⅲ standard) within 40 seconds. Firstly

experiments are conducted separately by adding CaO and active micron iron. Subsequently

phosphorus-containing wastewater is treated using the active m

icron iron/CaO composite system

and its phosphorus removal mechanism is studied. Finally

stability tests are carried out

followed by continuous flow experiments under simulated field conditions. Experimental results show tha the combined addition of CaO and active micron iron can meet the surface water class Ⅲ standard for phosphorus in wastewater within 40 seconds. H

-HCl accelerates the oxidation and corrosion of mZVI

providing active adsorption sites Fe

effectively adsorbing phosphate ions and forming Fe-P compounds mainly composed of Fe

(PO

)

and FePO

. Through chemical precipitation

CaO reacts with phosphates to produce Ca-P compounds

mainly Ca

(PO

)

(OH)

achieving an organic combination of chemical precipitation and adsorption. In stability tests lasting up to 28 days and continuous flow experiments

the phosphorus concentration and pH value of the treated wastewater remain stable after treatment with active micron iron/CaO

meeting the surface water class Ⅲ standard within 40 seconds. These research findings provide a theoretical basis for the emergency treatment of phosphorus-containing wastewater.
