Germany's rural sewage treatment method is also quite high, they use a diversionary sewage treatment method, which is also more environmentally friendly and can also be utilized for waste.
First of all, they have not connected to the drainage network in the more remote rural constructed advanced membrane bioreactors, usually the rainwater and sewage collected separately, and then through the advanced membrane bioreactors to the sewage purification. This system not only reduces the cost of sewage treatment, but also obtains nitrogen in the process of purifying sewage, thus achieving the purpose of turning waste into treasure and enhancing the fertility of rural land.
And then there is the PKA Wetland which is composed of two major systems, the media layer and the wetland plants, utilizing these two major systems **** the same ecosystem created, which integrates the physical, chemical, and biological efficacy of three kinds of efficacy, so that the effect of sewage treatment plays the greatest role. This process is mainly the rural life of sewage through the water pipeline, convergence into the sedimentation tank, and then after the sedimentation tank of the four layers of screening, and then through the PKA wetland to do the purification process, and finally to reach the discharge standard or used for irrigating farmland and so on. And the operation of this system does not require chemicals, it uses all the materials are from nature, the surrounding environment will not cause secondary pollution. the surface of the PKA wetland is very dry, there will be no water, all the formation of a green landscape, the usual operating costs are also very low, the operation process is also very simple, the management is particularly convenient.
There is also the Diversified Wastewater Classification System, which classifies wastewater into rainwater, graywater, and blackwater. Gray water means sewage generated from daily life such as kitchen, bathing and washing clothes, while black water refers to toilet sewage discharged through vacuum-type toilets. Rainwater from the roofs and hard surfaces of housing is collected by rainwater pipes and either reaches the nearby surface water or flows into a soakaway pond installed in the residential area. This seepage pond is also part of the neighborhood's landscaping facilities, changed into a special shape and environmental design, from the surface looks like part of the landscape, the bottom of the pond is caused by gravel, etc., so that the rainwater in the pond naturally seeps down and sinks into the groundwater.
