    Introduction to German Decentralized Wastewater Treatment

    kinglv2018-07

    The German decentralized wastewater treatment model has a long history. On the basis of the centralized sewage treatment mode adopted in the past, the decentralized sewage treatment method is adopted to promote the optimization and renewal of the sewage treatment technology, so that it gradually matures and is in the sewage treatment. A global leader. Today, Kinglv will bring you all the experience of sewage treatment in Germany.

    In the specific implementation process, Germany adopts the principle of upstream priority according to the geographical location and topographical features of the city, and clearly allocates the boundaries between the regions, combined with the advantages of centralized sewage treatment facilities, and enhances the decentralized system for sewage. The processing power makes it more in line with the needs of this era. At the same time, the construction of decentralized sewage treatment facilities is also based on the principle of local conditions, such as the use of advection or subsurface wetlands in plains and plateaus, that is, decontamination of clean water and environmental landscape; the use of vertical flow constructed wetlands in hilly areas is the highest The advantage of difference is to make the water interception and over-water area in the river channel increase obviously, thus creating a good and harmonious ecological environment.

    Germany's wastewater treatment technologies are also diverse, including decentralized wastewater treatment technologies such as physical and chemical treatment technology, biological treatment technology, ecological treatment technology and combination technology. In terms of the choice of technology, Germany has found through long-term exploration that on the basis of ecological design, constructed wetland technology can have higher advantages in terms of cost and processing effect.
