On October 21, 2023, the first Environmental Monitoring Frontier Technology and Conversion Application (Qingdao) Forum came to a successful conclusion. Our company was invited by the organizer to participate in this event and showcased core products such as LL series BOD-Q water quality analyzer, carbon nitrogen ratio intelligent regulator, and microbial growth promoter. On the forum, the company's technical consultant presented a report titled "Development and Application of Key Equipment for Rapid Detection of BOD in Water Quality", providing an efficient and accurate intelligent solution to the problem of how to quickly and accurately regulate biodegradability in wastewater treatment processes, which has been widely recognized by experts and scholars. During the exhibition, Academician Liu Wenqing once again came to the company's booth for guidance and gave our products high praise. This event promoted multiple products and played a positive role in expanding the market.
