technical field

The invention belongs to the technical field of rainwater runoff pollution control equipment, and in particular relates to a rainwater rapid treatment equipment integrating supermagnetic coagulation sedimentation and online disinfection.

Background technique

The second generation: Most of the traditional sewage treatment technologies such as MBR and A/O are used. The degradation of pollutants takes a long time, the degradation rate of pollutant indicators is low, and manual operation is required for operation and maintenance, which will be gradually replaced. The third generation; the combination of cyclone, sedimentation and other physical treatment technologies and traditional biological treatment technologies is often used. The degree of automation is low, the quality of the effluent is unstable, and chemicals need to be added, resulting in high operating costs.

A/O treatment process: AO method is the abbreviation of the first letter of the English Anaerobic-Oxic (anaerobic-aerobic method), which is the most widely used sewage treatment process in my country. The main advantages include: good denitrification and dephosphorization effect, no fear of sludge bulking, stable process operation, low operating requirements, and no need for dosing under normal conditions. The disadvantages are: large floor space, large one-time investment, and high operating costs.

2. MBR membrane treatment process: MBR, also known as Membrane Bio-Reactor, is a new type of water treatment technology that combines membrane separation unit and biological treatment unit. According to the structure of the membrane, it can be divided into flat membrane, tubular membrane and hollow fiber membrane, etc., and can be divided into microfiltration membrane, ultrafiltration membrane, nanofiltration membrane, reverse osmosis membrane, etc. Its main advantages include: high quality and stable effluent quality, less excess sludge output, small footprint, no restrictions on installation occasions, removal of ammonia nitrogen and refractory organic matter, convenient operation and management, easy to achieve automatic control, etc. The disadvantage is the operating cost. High, serious membrane pollution, high energy consumption.
