[0044] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.
[0045] The difference between the special sewage treatment and recycling method for animal breeding bases is that it includes the following steps:
[0046] Step 1), the sewage mixed with animal feces is input into the grid deletion tank for pretreatment, and the pretreated sewage with high organic matter and bacterial content is filtered out after the feces are separated from water;
[0047] Step 2), placing the pretreated sewage treated in step 1) into a filter tank filled with multi-layer mineral materials, and performing secondary sewage treatment;
[0048] Step 3), discharging the secondary treatment sewage treated in step 2) into a clear water sedimentation tank;
[0049] In step 4), the clean water treated in step 3) is reused as animal washing water or drinking water for recycling.
[0050] The step 2) is specifically as follows: the ...
