Key innovations
The innovation lies in connecting a single-stage completely mixed reactor in series into a cascade plug-flow reactor, which greatly improves the removal efficiency of ammonia nitrogen, organic matter, and algae toxins and the biological algae removal effect, reduces the amount of subsequent chemicals, and improves the safety of drinking water.
Potential economic benefits
Reduce the amount of coagulants and disinfectants and significantly reduce operating costs. Improve water quality safety, improve pollution removal capabilities, and increase economic benefits of water plants.
Potential climate benefits
This technology directly reduces carbon emissions in production, transportation and use by reducing the amount of coagulants and disinfectants. At the same time, high-efficiency water treatment can reduce the subsequent process load, thereby reducing related energy consumption; improving factory water quality is also conducive to the recycling of water resources, reducing the need for new water source development and treatment, and indirectly realizing carbon reduction benefits.

Solution details
Introduction to the results: This technology uses the principle of reactor to connect single-stage reactors with completely mixed flow characteristics in series to form a cascade reactor with push-flow characteristics, which greatly improves the removal efficiency and biological removal of ammonia nitrogen, biodegradable organic matter, and algae toxins. Algae removal effect can also reduce the amount of coagulants and disinfectants in subsequent processes, and improve the safety of drinking water. This technology is suitable for process transformation of waterworks, which can greatly improve the pollution removal capacity of the water plant and improve the quality of factory water.
