Research Progress of Flocculants in Industrial Waste water Treatment
摘要
Abstract
[Objective]This paper comprehensively reviews the research and application progress of flocculants in industrial wastewater treatment,with a particular focus on solving the problem of difficult to degrade pollutants in industrial wastewater,especially heavy metal ions.This research is of great significance for protecting the water environment,reducing environmental pollution,and achieving resource recycling and reuse.It provides scientific theoretical basis and technical support for industrial wastewater treatment,in order to achieve more efficient and environmentally friendly treatment effects.[Methods]The paper comprehensively introduces the classification and characteristics of inorganic,organic,microbial,and composite flocculants,and deeply analyzes their application effects in wastewater treatment in industries such as electroplating,metallurgy,and pharmaceuticals.The study adoptes methods such as chemical modification and flocculant combination to improve treatment efficiency,while exploring the mechanism of flocculant action.[Results]The study finds that the treatment efficiency can be significantly improved through chemical modification and flocculant combination,for example,polyacrylamide(PAM)achieved a Cu(Ⅱ)removal rate of up to 98.7％in simulated wastewater,and microbial removal rate reached 98.7％in simulated wastewater.The removal efficiency of flocculant GA1 for Pb(NO3)2 reach 99.8％.In addition,composite flocculants have shown potential in improving removal efficiency and reducing costs.[Conclusion]Future research should focus on the environmental impact assessment of flocculants,resource recycling,development of environmentally friendly flocculants,and efficient flocculant design for specific pollutants.These research directions will help achieve efficient treatment of industrial wastewater and sustainable utilization of resources,which is of great significance for environmental protection and sustainable industrial development.This review provides valuable reference information for the field of industrial wastewater treatment,which helps to promote the development and application of environmentally friendly flocculants to achieve green and efficient industrial waste water treatment.关键词
