Home Bailonggang Wastewater Treatment Plant deodorisation upgrading
As China moves rapidly towards urbanisation, more wastewater treatment plants in Chinese cities are surrounded by residential areas, causing increasingly serious conflicts between the plants and nearby residents over odour emissions.
This project was China’s first fully closed and full-range collection and treatment project designed for more than 100 treatment facilities and up to 18,000 sources of high concentration odour.
Based on air flow and dynamics simulation, it features an innovative low clearance structure of much lighter and longer prefabricated components that are corrosion proof and UV resistant, enabling an optimal continuous separation of irregular flows of odour in the air into regular flows through the “egg-shell-shaped” structure that ensures the formation of internal plug flows for the successful induction of odour into the pipes.
The peak clipping stage treatment technology is used for the first time to treat odour in different categories through a variety of optimal solutions, such as solvent dissolution, gas phase adsorption, molecular scission, oxidation, biological decomposition, and chemical neutralization, which have successfully lowered the odour concentration from the magnitude of millions to hundreds or less.
