Hog fowl mixed wastewater treatment method and recycled pig fowl mixed wastewater treatment system

摘要

To be able to utilize not only large-scale pig farmers but also small-scale pig farming businesses, it is possible to easily and efficiently perform solid-liquid separation treatment of solid components and liquid components of pig fowl mixed waste water, It is an object of the present invention to provide a mixed wastewater treatment method. SOLUTION: In the same agglutination reaction tank, a plurality of flocculant aqueous solutions are simultaneously added to pig fowl mixed waste water exhibiting alkalinity in the vicinity of the pH value 7 and agitated to form a first flocculation reaction and a coarse floc And the second agglutination reaction in the same agglutination reaction tank are carried out substantially at the same time, and the first agglutination reaction and the second agglutination reaction are completed, whereby the solid component of the pig fowl mixed waste water and And a liquid component are completely solid-liquid separated to produce sludge and clarified water.
