Analysis on the Application of Biochar in Sewage Treatment
As a new type of carbon material,biochar has properties similar to activated carbon and can be used for treating sewage.The experiment takes bamboo powder and KHCO3 as raw materials to prepare biochar,and uses a biochar dynamic adsorption device to treat simulated sewage,and collects actual sewage samples to analyze the effectiveness of the biochar adsorption+chlorination disinfection combination process in treating pollutants and pathogenic microorganisms.During this process,the influence of bamboo powder and KHCO3 dosage on the performance of biochar is analyzed,and the penetration curves of pollutants and pathogenic microorganisms are studied,and the actual sewage treatment effect is verified.After biochar adsorption and chlorination disinfection treatment,the concentration of pollutants and the number of pathogenic microorganisms are significantly reduced,and the effluent can meet the relevant discharge standards and can be reused.Research has shown that biochar can effectively treat sewage,remove pollutants and pathogenic microorganisms,and play an important role in the safe discharge and secondary utilization of sewage.
