TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The mechanically working drainage mechanism (35) (second process step), where the material mixture treated in the drainage mechanism and/or separated solid (31) from a mechanical process water purification process are drainable by mechanical working drainage mechanism (35). The washing device is designed as dynamically working washing device (which alternatively oscillated or rotates in two directions and preferably a sieve-shaped lateral surface (21)) and as dynamic filtration, rotary, sieve-shaped washing drum and/or as oscillating or shaking filter (where the material mixture is treated in such a way that easily soluble organic compounds and an inert abrasive materials are dischargeable with the process water discharge (24) by feeding of oxidizing or oxidizing working process water feed). In the washing device of the first process step, homogenization by mixing and transporting in vertical and horizontal direction are obtained by pumping and/or agitating mechanism (27), where the mechanism is preferably attached to an interior wall of the washing device.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: In the solid path at the process step (4) the material mixture treated in the first process step is drained by a mechanical-drainage mechanism (35). In the water path at the process step (5) a mechanical treatment of the process water discharge (24, 38) obtained from the process step (3, 4) takes place. The process step (9) in the water path directly follows the process step (3, 5). The washing and hydrolysis process in the process step (3) is intended preferably in a dynamically working washing device, which alternatively rotates or oscillates in two direction. In the process step (4) the separated solids (31) are drained off from the mechanical process of water processing step (5). In the process step (9), the process water discharge (49) from the fermentation process step and/or methanation process step (7) and the process water discharge (50) from the solid-sludge separation process step (8) is subjected to a biological and/or physiochemical treatment. In the process step (9), the process water (33) from the process step (5) is directly subjected to a biological and/or physiochemical treatment without inserting one of the process steps (6, 7, 8). Between the fermentation process step (7), and the process step (8) and (9), a solid-sludge separation takes place. The process water discharge (55) from the process step (9) oxidizes and/or oxidized by the biological and/or chemical method. The material mixture is subjected to a mechanical pretreatment e.g. by milling, filtration and withdrawal of the recycled and breakdown materials, before the material mixture is treated in the first process step. The first process step is designed as washing mechanism, preferably as dynamic filtration, rotary, sieve-shaped washing drum (11) and/or oscillating or shaking filter, where the material mixture is treated by feeding an oxidized or preferably oxidizing working process water in the form of washing liquid from the third process step (9), where the easily soluble organic compounds and inert abrasive materials with a process discharge water (24) are discharged, and the material mixture to be treated, and/or the process discharge are oxidized. The material mixture is treated by feeding an oxidized or preferably oxidizing working process water feed in the form of washing liquid from the third process steps such that the decomposition and/or conversion, preferably hydrolysis of the material mixture and/or process water. The material mixture is treated by feeding an oxidized or preferably oxidizing working process water feed in the form of washing liquid from the third process step, such that that the decomposition, conversion or preferably the hydrolysis of the material mixture and/or the process water discharge are promoted. The first process step, second process step (4) and the third process step takes place continuously or batch-wise, where the retention time of the material mixture, preferably in the first process step is 1-24 hours, preferably 4-8 hours. The decomposition and the hydrolysis of the supplied material mixture and the process discharge water takes place in the first process step by the partial or complete use of oxidized and/or oxidizing working process water discharge from the third process step as process water feed in the form of washing liquid. The first process step contains a washing device, preferably rotator washing drum, with which a filtration preferably with a particle size from 5-30 mm, preferably 8-15 mm, and exhibits a length from 8-20 m and a diameter from 24 m. In the first process step soluble organic material components, inert materials, fibrous materials, fine substance adhered to the material mixture are washed. The oxidized and/or oxidizing working process water discharge from the process step (9) are supplied in the hydrolysis step to form aerobic conditions in the hydrolysis step. The process water discharge of the first process step and/or process water discharge (38) from the second process step are treated in a mechanical process water purification process (5), preferably for the separation of non- or hardly- biodegradable materials e.g. inert materials (44), rough and fibrous materials (31). The process water discharge water (24) from the first process step and/or the process water discharge (38) from the second process step (4) after treated with mechanical process water purification process as process water discharge (33), is subjected to a fermentation process for the formation of recyclable products such as acetic acid, lactic acid, butyric acid or biogas. In the process step (9) the process water discharge (33) from the process step (5) is directly subjected to a biological and/or physiochemical treatment, without the insertion of one or more process steps (6, 7, 8). The supply of the process water feed to the material mixture in the form of washing liquid takes place using the washing device by a charge hole (12) or by sprinkle mechanism (13). By the addition of process water feed in the form of washing liquid, the washing device is partly filled up to half of its diameter (26), such that more intensive rinsing and washing of preferably soluble, organic material components and adhering fine substance, and an oxidizing effect of the process water feed takes place, where the addition of the process water feed takes place in the same or counter flow direction to the material mixture. The discharge of the process water (48, 49) treated in the fermentation process are supplied completely or partly to the process step (8, 9) and subsequently subjected to a solid-sludge separation process. The process water discharge (50) is subjected totally or partly to the process water treatment (9), preferably biological and/or chemical oxidation of the organic and inorganic compounds, biological and/or physiochemical contaminant removal process, removal of carbon, nitrogen, phosphorus, heavy metals and organic halogen compounds, where the process water discharge (55) is treated in such a way that the it is supplied totally or partly to the first process step and/or partly to the mechanical process water purification (5) and/or to the hydrolysis step. Solid materials such as floating-, fibrous- and coarse substance, which are separated in the mechanical process water purification are fed back in to the first process step and/or second process step. The washing liquid is heated at at least 35 degreesC, preferably 40-70degreesC to accelerate the washing- and biological process and/or to obtain a hygienization of the treated material mixture. The hydrolysis step is subjected to a continuous or batch-wise aeration process (46). The purified process water discharge (55) is recyclable in the hydrolysis step and/or in the first process step. The treatment process further comprises washing the material mixture with process water, and subjecting the process water to a hydrolysis in the hydrolysis step. The process water discharge (53) is oxidizable and/or reducible in the process water treatment (9) with biological and/or chemical process. Preferred Components: The material mixture further comprises of domestic-, commercial- and/or industrial- wastes.
