AI Technical Summary
Urban wastewater treatment plants suffer from problems such as low efficiency, high cost, difficulty in process control, difficulty in controlling effluent COD, and increased sludge production in total nitrogen removal, making it difficult to reduce total nitrogen in effluent to below 10 mg/L.
An integrated modular reactor for total nitrogen removal from urban wastewater was designed. It adopts a modular structure and includes components such as a tank, a detachable denitrification device, nitrification packing, a screen, and a stirring blade. The granular sulfur self-oxygenating denitrification packing fully contacts and reacts with nitrates in the water. Combined with the stirring blade and the layered structure, it achieves efficient nitrogen removal.
It improves the continuity and stability of wastewater treatment, reduces the impact of equipment failure, enhances the versatility and flexibility of the equipment, reduces operating costs, and achieves a high efficiency in total nitrogen removal.
