摘要:
Waste or organic material is compressed at a pressure sufficient to burst cells, for example 50 bar or more, and separated into a dry fraction and a wet fraction. The wet fraction is treated in an anaerobic digester to produce biogas after removing grit. The wet fraction is diluted, preferably with sludge, before it is degritted. Optionally, floatables are removed from the fraction before it is added to the digester.

A plant for treating waste comprising a treatment tank (12) configured to contain the waste and a separation liquid to separate, by floating, in the waste, parts of inorganic material from parts of organic material. The plant comprises an apparatus for anaerobic digestion (14) and a delivery circuit (13) that connects the treatment tank (12) and the anaerobic digestion apparatus (14) in order to transfer the separation liquid and the organic material from the treatment tank (12) to the anaerobic digestion apparatus (14), configured to treat the organic material separated in the treatment tank (12) and to produce combustible gas and biomass.

The present invention discloses a resource utilizing method of refuses in urban and rural areas in which an acidification and anaerobic treatment tank, an additional anaerobic treatment tank, a biogas gathering tank and a gas generator set are provided and a gas inlet of said gas generator set is connected to the biogas gathering tank through pipes. The method comprises a refuses reception step, a uniform refuses distribution step, a primary magnetic separation step, a primary crushing step, a primary elutriation and floatation step, a uniform cutting step, an acidification and anaerobic treatment step, a selection and separation step, a buffering and adjusting step, an additional anaerobic treatment step and a sludge sedimentation and concentration step. In the present invention, the refuses need not pre-sort as the sorting and selection of the refuses are made throughout the overall process of the inventive refuses utilizing method. Thus the biggest bottleneck of the constraints in refuses disposal is removed. The present invention can make the anaerobic treatment method continuatively dispose the refuses, thereby thoroughly solving the problem that the non-anaerobic refuses such as waste plastics, waste fibers etc. can't be recycled and completely recycling resources in the refuses.

The present invention relates to an improved method for reclaiming the individual components of synthetic or artificial turf product in a form almost similar to their original outset. The result is achieved by a method in which the turf after downsizing is subjected to at least three specific separation steps in a specific order hence the separation is based on size, specific gravity and specific gravity, size and shape. The result is also achieved by a corresponding system.
摘要:
Apparatus for cleaning contaminated aggregate comprising: at least one channel arranged in use to receive a liquid containing contaminated aggregate; and first and second banks or groups of at least one jet. The first bank or group of jets is arranged to direct pressurised fluid at the contaminated aggregate in order to agitate the contaminated aggregate against a surface thereby promoting separation of cleaned aggregate from contaminated aggregate. The second bank or group of jets is arranged to direct and/or urge the cleaned aggregate to a drainage outlet.
