The invention relates to the technical field of biogas residues, in particular to a biogas residue processing device for improving non-point source pollution. The biogas residue processing device comprises a separating bin, wherein a feeding hopper is arranged on one side of the top of the separating bin; a rotating support is arranged in the separating bin; an uncapped cylindrical centrifugal barrel is rotationally arranged on the rotating support; the lower end of the feeding hopper is located above the centrifugal barrel; and a filtering cartridge is arranged inside the centrifugal barrel. An alkali liquor chamber is arranged in the biogas residue processing device; heavy metal is precipitated by conveying alkali liquor, and then is centrifugally separated by matching the centrifugal barrel with the filtering cartridge, and a good separating effect is realized, so that sewage containing the heavy metal is separated from the biogas residues, and hazards of the heavy metal to crops are avoided; and in addition, the biogas residue processing device is provided with a cleaning brushing board which can be used for automatically cleaning the inner wall of the centrifugal barrel, and is good in cleaning effect and simple and convenient to maintain.
Description
technical field [0001] The invention relates to the technical field of biogas residue processing, in particular to a biogas residue processing device for improving non-point source pollution. Background technique [0002] Biogas residue is rich in nitrogen, phosphorus, potassium and a large number of elements, and also contains trace elements such as boron, copper, iron, manganese, zinc, etc., which play an important role in crop growth. During the processing of biogas residues, solid-liquid separation is generally carried out. During this process, the separation chamber tends to accumulate residues, which is very inconvenient to clean. On the other hand, the heavy metals contained in biogas residues will pollute the soil and affect sustainable development. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings of difficult cleaning and easy pollution in the prior art, and propose a biogas residue processing device that improve...
