Title:

HOG EXCREMENT AND URINE MIXTURE WASTEWATER TREATMENT METHOD AND RECYCLING TYPE HOG EXCREMENT AND URINE MIXTURE WASTEWATER TREATMENT SYSTEM

Document Type and Number:

Japanese Patent JP2017217610

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide a hog excrement and urine mixture wastewater treatment which not only large scale pig farm business operator, but also small scale pig farm business operator can use and which can conduct a solid solution separation treatment of a hog excrement and urine mixture wastewater into a solid component and a liquid component easily and efficiently.SOLUTION: By adding a plurality of flocculant aqueous solutions to a hog excrement and urine mixture wastewater exhibiting alkalinity near pH value of 7 in same flocculation reaction tank at almost same time and stirring them, conducting a first flocculation reaction for forming a fine floc and a second flocculation reaction for forming a coarse floc in the same flocculation tank at almost same time and completing the first flocculation reaction and the second flocculation reaction, a solid component and a liquid component of the hog excrement and urine mixture wastewater is completely solid liquid separation treated and sludge and clear water are generated.SELECTED DRAWING: Figure 1
