The invention discloses a method and application of removing nano-plastic pollutants in water body by using natural limestone particles. In this method, limestone and microplastics are first processed into different particle sizes and concentrations, and a fixed bed device is used to simulate the rapid sand filter (RSF) process. , inject the microplastic solution into the column, collect the sample, measure the concentration, draw the relationship between the normalized effluent concentration and the pore volume, obtain the penetration curve of the nanoplastic, and calculate the removal efficiency according to the mass recovery rate. The removal rate reaches 70%. Works well. |
