Special sewage treatment and cyclic utilization method and filtering pool for animal cultivation base

Abstract

The invention relates to the fields of sewage treatment and water quality improvement, in particular to a special sewage treatment and cyclic utilization method and a filtering pool for an animal cultivation base. The special sewage treatment and cyclic utilization method for the animal cultivation base comprises the following steps of: (1), delivering sewage mixed with animal feces into a grid pool to be pretreated, separating the feces and the water, and filtering organic matters and pretreatment sewage with high bacterium content; (2), placing the pretreated sewage through the pretreatment in step (1) into the filtering pool filled with a plurality of layers of mineral materials for carrying out two-stage treatment on the sewage; (3), discharging the two-stage treatment sewage after treated in the step (2) into a clean water sedimentation pool; and step (4), recycling the clean water treated in step (3) as animal cleaning water or drinking water for cyclic utilization. The invention has the advantages of high sewage treatment speed, high cleaning efficiency, less implementation cost and wide application.

Description

technical field [0001] The invention relates to the fields of sewage treatment and water quality improvement, and is mainly used in military dog ​​breeding bases or other civilian livestock breeding units, especially a special sewage treatment recycling method and filter for animal breeding bases. technical background [0002] The disadvantage of the conventional sewage treatment system is that the system construction investment is large, the operation and maintenance costs are high, and the sewage is prone to secondary pollution after treatment. Especially for small and medium-sized animal breeding units, due to the characteristics of high construction costs, high operation and maintenance costs, conventional sewage treatment systems cannot adapt and cannot be implemented. In addition, the heavy metal content of water sources in some areas exceeds the standard, which increases the difficulty of conventional sewage treatment systems.
