Embodiment Construction

[0032] figure 1 Shows a method concept for the aerobic treatment of waste materials that are a burden on the environment, in particular with a dry matter content (TS-Gehalt) of 50% to 65%, such as garbage, waste from large kitchens, waste from the food industry, vegetables and other regrown organic waste, sewage sludge and fermentation sludge and biological residues from beverage production, such as sugar-containing mash (Maischen).

[0033] The organic substances 1 that are harmful to the environment are fed directly 2 or via a mechanical treatment device 3 upstream of a percolation device 4 or a comminution device 5 .

[0034] The mechanical treatment unit 3 has screening, sorting and comminuting steps, wherein the screening fraction 3.1 is preferably fed to the percolation unit 4 with a particle size of 50 mm to 250 mm and preferably to the comminution unit 5 with a particle size > 250 mm . When the maximum particle size of the sieve fraction 3.1 is about 50 mm, it is pre...

Abstract

The invention relates to a method for mechanical and biological processing of wastes, in particular residual wastes consisting of physico-chemical processing (PCA) for removing nitric acid from processed water which is exempt of organic components. Said invention also relates to a hybrid reactor consisting of a fixed bed, a sludge extraction device and a device for supernatant destruction.

Description

technical field [0001] The invention relates to a method and a mixing reactor for treating waste materials, in particular refuse, according to the preambles of claims 1 and 21 . Background technique [0002] A method of this type is known, for example, from PCT / EP02 / 09855. The problem with this waste disposal method is the disposal of the treatment water used in the biological treatment. This water carries organic matter that must be removed before being introduced into the purification plant / sewage. It is desirable to recycle the treated water, wherein the organic-depleted treated water fraction is returned as recycled water for biological treatment. [0003] However, it has been found that, with conventional solutions, the minimum concentrations of organic constituents required for trouble-free operation of the treatment process and required by legal regulations can only be reduced with high technical outlay. Contents of the invention [0004] In contrast, the object ...
