摘要:
为了解决高浓度含磷污水深度净化问题,探究矿渣硅酸盐水泥的除磷潜能,利用矿渣硅酸盐水泥对初始磷质量浓度为150 mg/L 的含磷废水进行吸附性能研究。结合扫描电子显微镜(SEM)、X射线衍射(XRD)等方法,对矿渣硅酸盐水泥磷吸附前后的表面形貌和晶体结构等进行表征和分析。吸附动力学实验结果表明:矿渣硅酸盐水泥可有效处理高浓度含磷废水,去除率可达90.3% ,吸附量可达27 mg/g,准二级动力学模型和颗粒内扩散模型能较好地解释其吸附动力学过程,除磷速率主要受化学反应速率限制,相比于表面吸附,颗粒内扩散是吸附过程中的决定性步骤。此外,吸附等温线研究结果表明:吸附过程可以用Freundlich和 Langmuir方程描述,相关系数均在0.97以上,说明矿渣硅酸盐水泥既发生了单分子层吸附,又发生了多分子层吸附,且其表面不均匀活性位点略强于均匀活性位点,Langmuir模型预估其最大吸附量可达47 mg/g。通过正交试验得出最佳反应条件:pH值为7,初始磷质量浓度为150 mg/L,投加量为5 g/L,吸附时间为18 h。在溶液不同初始pH值的条件下,矿渣硅酸盐水泥磷饱和吸附后出水表明其可以有效中和过量的酸或碱,具有良好的缓冲特性,化学吸附中的配位体交换是其主要的除磷机理。矿渣硅酸盐水泥适用于高浓度含磷废水,也适用于pH值不稳定的含磷废水。
Abstract:
This study aimed to solve the problem of deep purification of high concentration phosphorus wastewater and to explore the phosphorus removal potential of portland blast furnace slag cement.The adsorption of the wastewater containing 150 mg/L TP on portland blast furnace slag cement was discussed.Combined with scanning electron microscopy(SEM)and X-ray diffraction(XRD), the surface morphology and crystal structure of portland blast furnace slag cement before and after phosphorus adsorption were characterized and analyzed.The results of adsorption kinetics experiments showed that portland blast furnace slag cement as a adsorbent could treat high phosphorus-containing wastewater, removal rate up to 90.3%, adsorption capacity up to 27 mg/g, the adsorption kinetic process could be well explained by using pseudo-second-order kinetic model and intra-particle diffusion model, the dephosphorization rate is mainly limited by the chemical reaction rate, compared with surface adsorption, intra-particle diffusion is the decisive step in the adsorption process.In addition, isotherm studies showed that phosphorus adsorption on portland blast furnace slag cement fitted the Freundlich and Langmuir model, with the correlation coefficients over 0.97.The results indicated that both single-layer adsorption and multi-layer adsorption occurred in portland blast furnace slag cement, and the non-uniform active sites on the surface were slightly stronger than the uniform active sites, the maximum phosphorus adsorption capacity determined by Langmuir isotherm plot was 47 mg/g.Through orthogonal experiments, the optimal reaction conditions were as follows: pH is 7, initial phosphorus concentration is 150 mg/L, dosage is 5 g/L, contact time is 18 h.The portland blast furnace slag cement can effectively neutralize the excess acid and alkali, and has good buffering characteristics, which may be related to the protonation and deprotonation of the metal ions, the ligand exchange in chemisorption was the main mechanism of phosphorus removal.Portland blast furnace slag cement is suitable for high concentration of phosphorus containing wastewater, also suitable for pH unstable phosphorus containing wastewater.
