NOVELTY - Semi-centralized treatment and preparation of biogenous substance streams in agro-urban settlement systems by recycling and/or converting liquid and solid organic biomasses including sewage, biowaste, crop residues, green waste and other biogenous residues in a recycling economic system, comprises subjecting black water or similar wastewater to a pre-filtration in a black-water cycle by at least one organic sorption filter (6) for receiving organic loads and plant nutrients from black water or similar wastewater in a filter material mixture comprising containers and/or drivable clamps.    USE - The method is useful for semi-centralized treatment and preparation of biogenous substance streams in agro-urban settlement systems.    ADVANTAGE - The method: ensures efficient resource-recycling; achieves a good erosion control; and utilizes humus substrate, thus it increases the soil quality and improves water holding capacity of soil.    DETAILED DESCRIPTION - Semi-centralized treatment and preparation of biogenous substance streams in agro-urban settlement systems by recycling and/or converting liquid and solid organic biomasses including sewage, biowaste, crop residues, green waste and other biogenous residues in a recycling economic system, comprises subjecting black water or similar wastewater initially to a pre-filtration in a black-water cycle by at least one organic sorption filter (6) for receiving organic loads and plant nutrients from black water or similar wastewater in a filter material mixture comprising containers and/or drivable clamps, which have equipment to record and transfer the remaining liquids at the bottom. The organic loads and nutrients contained in the black water or similar wastewater remain in the organic sorption filter and the pre-filtered black water is subsequently supplied to a black-water leach (14), which comprises at least one sealed basin, tanks and/or beds, a planted vegetation, a filter substrate, a distributor system, a collective drainage and a cistern arranged below or next to the black-water leach for storing the cleaned black water, and the water filtered through the black-water leach is provided for watering plants or green spaces. A gray-water cycle is provided, in which gray water or similar wastewater is passed over a gray-water leach (30), which comprises at least one sealed basin, tanks and/or beds, a planted vegetation, a filter substrate, a distributor system, a collective drainage and a cistern arranged below or next to the gray-water leach for storing the cleaned gray water. The water filtered through the gray-water leach is first subjected to a sanitation and subsequently used as household service water, is fed to business entities of the watershed area and/or for watering greenhouse crops, gardens or agricultural land. An INDEPENDENT CLAIM is also included for a semi-centralized plant for the treatment of biogenous substance streams from a drainage area by collecting and/or processing of liquid and solid organic biomass into valuable substance streams, comprising organic sorption filter (6) for receiving organic loads and plant nutrients from black water or similar wastewater, a device for sanitizing composting (intensive composting) of the saturated filter material mixture of the organic sorption filter comprising containers and/or clamps with charging devices, a device for drying a humus substrate prepared in the previous devices comprising containers and/or drivable clamps, a black-water leach for treating the pre-treated black water, a gray-water leach for the treatment of gray-water and/or weakly contaminated process water, a hygienization unit for treating the purified gray-water from the gray-water leach, and a retention and buffer pond for buffering the excess gray-water, and equipments for the transport and storage of the treated black and gray-water and similar wastewater.
