Whenever we talk about industrial wastewater treatment, flocculation technology is always an unavoidable topic. With the advancement of science and technology, the application of flocculation technology in wastewater treatment has also made new progress. This article will discuss the new progress of industrial wastewater flocculation technology in detail from the following five aspects, aiming to share the latest professional knowledge with industry insiders. First of all, the innovation of flocculant types is undoubtedly one of the most noteworthy developments in recent years. Traditional inorganic flocculants such as aluminum sulfate and polyaluminum chloride have been widely used in practical applications, but they have certain processing efficiency bottlenecks. In recent years, the research and application of biological flocculants and composite flocculants have gradually increased. For example, chitosan-based flocculants are gradually being favored by the industry because of their environmental protection and high efficiency. This new flocculant can not only efficiently remove suspended matter, but also reduce the risk of secondary pollution. Secondly, new flocculation process technologies have been widely used and improved. Traditional flocculation processes usually include multiple steps such as coagulation, flocculation, and sedimentation, which are cumbersome to operate and have high energy consumption. In recent years, new flocculation processes based on membrane technology and nanotechnology have been widely studied and applied. For example, electroflocculation technology combines the advantages of electrochemical reactions and induces the aggregation of suspended particles through electric fields, which not only improves the flocculation effect but also greatly reduces the use of reagents. Thirdly, the introduction of intelligent monitoring and automatic control technology has made it possible to optimize and regulate the flocculation process in real time. Through online monitoring systems and intelligent control systems, water quality parameters can be monitored in real time and adjusted accurately to improve the efficiency and stability of flocculation treatment. For example, the optimization model established using machine learning algorithms can intelligently adjust the flocculant dosage and coagulation time based on treatment effect feedback, thereby achieving refined management. Fourth, reducing the economic cost and environmental burden in the flocculation process is one of the current research hotspots. Although the new flocculation technology has significantly improved the treatment effect, its cost issue is still a bottleneck for its promotion and application. By optimizing the use and matching of flocculants, improving equipment design and process flow, the cost can be effectively reduced while ensuring the treatment effect. For example, the use of recyclable flocculants and high-efficiency and low-energy flocculation equipment is the main direction of future technological development. Finally, combined with actual cases, the application effect of flocculation technology in various industrial fields is further highlighted. Whether in the chemical, pharmaceutical, metallurgical or food processing industries, the application of flocculation technology has achieved remarkable results. For example, in a wastewater treatment project of a large chemical plant, after the application of the electro-flocculation process, the COD removal rate of its wastewater increased by 30% and the operating cost was reduced by half. Such successful cases provide strong support for the comprehensive promotion of flocculation technology. In general, industrial wastewater flocculation technology has made significant progress in flocculant innovation, new process application, intelligent monitoring, cost control and application effect. We look forward to more technological breakthroughs in the future to promote industrial wastewater treatment towards a more efficient and environmentally friendly direction. We hope that the sharing of this article can provide valuable reference for colleagues in the industry and inspire future work.
