The fecal pollution processing system of the present embodiment has practicability: each equipment of the fecal pollution processing system is separated by solid-liquid separation speed Fastly, for desiccation solid dirt water content after separation between 60%-80%, slag discharge amount and water content can be by adjusting each equipment Parameter adjust, the feed (such as grass and concentrated feed) of applicable different components is readily transported, solid particless object is well suited as Fish meal and the raw material of organic fertilizer etc..

The fecal pollution processing system of the present embodiment has advance: at the fully integrated various excrement of the fecal pollution processing system Reason has the advantages that dirt-removing power is strong, many-sided without blocking, easy to clean, income height at low cost etc..

The above content is only the preferred embodiment of the utility model, for those of ordinary skill in the art, according to this reality With novel thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as Limitations of the present invention.
