The phosphorus content in sludge incineration ash is relatively high. Extracting and recovering it can effectively alleviate the contradiction between the supply and demand of phosphorus. Leaching of phosphorus from sludge incineration ash with nitric acid was studied. The effects of nitric acid concentration, leaching temperature, leaching time and the ratio of liquid volume to solid mass on the leaching rate of phosphorus were investigated. The restrictive links of phosphorus leaching were determined and the kinetic equation was established. The results show that under the conditions of nitric acid concentration of 1 mol/L, temperature of 298 K, leaching time of 60 min, stirring speed of 500 r/min, and liquid volume to solid mass ratio of 40 mL/1 g, the leaching rate of phosphorus reaches 91.36%. Internal diffusion control is the limiting link in the phosphorus leaching process, and the activation energy of the leaching reaction is 2.11 kJ/mol. The method has a relatively high phosphorus extraction efficiency. It is an efficient and feasible technology for recovering phosphorus from sludge incineration ash and can provide an important technical approach to alleviate the contradiction between supply and demand of phosphorus resources.

污泥焚烧灰中磷含量较高,加以提取回收能有效缓解磷的供需矛盾。研究了用硝酸从污泥焚烧灰中浸出磷,考察了硝酸浓度、浸出温度、浸出时间、液固体积质量比对磷浸出率的影响,并确定了磷浸出的限制性环节,建立了动力学方程。结果表明:在硝酸浓度1 mol/L、浸出温度298 K、浸出时间60 min、搅拌速度500 r/min、液固体积质量比40 mL/1 g条件下,磷浸出率达91.36%;内部扩散控制是磷浸出过程的限制环节,浸出反应活化能为2.11 kJ/mol。该法磷提取效率较高,是一种从污泥焚烧灰中回收磷的高效、可行技术,能为缓解磷资源供需矛盾提供一种重要的技术途径。

污泥焚烧灰中磷含量较高,加以提取回收能有效缓解磷的供需矛盾。研究了用硝酸从污泥焚烧灰中浸出磷,考察了硝酸浓度、浸出温度、浸出时间、液固体积质量比对磷浸出率的影响,并确定了磷浸出的限制性环节,建立了动力学方程。结果表明:在硝酸浓度1 mol/L、浸出温度298 K、浸出时间60 min、搅拌速度500 r/min、液固体积质量比40 mL/1 g条件下,磷浸出率达91.36%;内部扩散控制是磷浸出过程的限制环节,浸出反应活化能为2.11 kJ/mol。该法磷提取效率较高,是一种从污泥焚烧灰中回收磷的高效、可行技术,能为缓解磷资源供需矛盾提供一种重要的技术途径。

The phosphorus content in sludge incineration ash is relatively high. Extracting and recovering it can effectively alleviate the contradiction between the supply and demand of phosphorus. Leaching of phosphorus from sludge incineration ash with nitric acid was studied. The effects of nitric acid concentration, leaching temperature, leaching time and the ratio of liquid volume to solid mass on the leaching rate of phosphorus were investigated. The restrictive links of phosphorus leaching were determined and the kinetic equation was established. The results show that under the conditions of nitric acid concentration of 1 mol/L, temperature of 298 K, leaching time of 60 min, stirring speed of 500 r/min, and liquid volume to solid mass ratio of 40 mL/1 g, the leaching rate of phosphorus reaches 91.36%. Internal diffusion control is the limiting link in the phosphorus leaching process, and the activation energy of the leaching reaction is 2.11 kJ/mol. The method has a relatively high phosphorus extraction efficiency. It is an efficient and feasible technology for recovering phosphorus from sludge incineration ash and can provide an important technical approach to alleviate the contradiction between supply and demand of phosphorus resources.
