Facing the fast-developing economy, the discharge of wastewater is also increasing. The particularity of its water quality and discharge has brought severe challenges to the existing treatment process, improving and improving the existing treatment process, and at the same time researching and developing new unique small and medium-sized sewage The processor is imminent. What are the technologies for sewage treatment?
1. Constructed wetland sewage treatment technology
Constructed wetland is artificially constructed and controlled to operate on the ground similar to marshland. Sewage and sludge are controlled and distributed to the artificially constructed wetland. The sewage and sludge are mainly used in the process of flowing in a certain direction. A technology for the treatment of sewage and sludge with the triple synergy of physics, chemistry, and biology of soil, plants, artificial media, and microorganisms.
2. Anaerobic unpowered sewage treatment technology
Anaerobic biological treatment technology is a process in which facultative anaerobic and anaerobic microbial groups convert organic matter into methane and carbon dioxide under anaerobic conditions. Anaerobic sewage treatment technology has the advantages of low cost, low operating cost, and energy recovery. It has been widely studied and applied in the treatment of dispersed domestic sewage.
3. Membrane bioreactor (MBR process)
Membrane bioreactor is a new type of water treatment technology that combines membrane separation unit and biological treatment unit. It replaces the secondary sedimentation tank with membrane modules to maintain a high concentration of activated sludge in the bioreactor and reduce the area occupied by sewage treatment facilities. And reduce the amount of sludge by keeping the sludge load low. The process mainly uses membrane separation equipment immersed in an aerobic biological tank to intercept the activated sludge and macromolecular organic matter in the tank.
Membrane bioreactor has the advantages of good treatment effect, impact load resistance, stable effluent water quality, less residual sludge, convenient operation and management, and space saving. With the increase of membrane flux, membrane cost is reduced and life is prolonged, and water resources are regenerated With increasing attention, membrane bioreactors will be extremely widely used in the field of sewage treatment, especially in the treatment and reuse of dispersed point source sewage. There are currently many membrane bioreactor production and application companies, and a number of demonstration projects have been established, which have achieved good environmental and social benefits.
