<p><P>PROBLEM TO BE SOLVED: To provide sewage treatment equipment for a livestock farm which can efficiently deodorize and purify sewage discharged from the livestock farm to recycle it as drinkable water for livestock, and the like. <P>SOLUTION: The sewage treatment equipment has a sewage supply means 1 that supplies livestock sewage 15 discharged from the livestock farm at a fixed sewage flow rate V<SB>1</SB>per hour, a lactic acid bacteria water supply means 2 that supplies lactic acid bacteria water 16 at a fixed lactic acid bacteria water flow rate V<SB>2</SB>per hour, a lactic acid bacteria regulating tank 3 that stores mixed liquid 18 of lactic acid bacteria at a predetermined volume V<SB>0</SB>and the sewage in which the supplied livestock sewage 15 and lactic acid bacteria water 16 are mixed, and aeration equipment 17 into which the mixed liquid 18 of the lactic acid bacteria and the sewage discharged from the lactic acid bacteria regulating tank 3 flows. The ratio of a volume V<SB>0</SB>of the mixed liquid 18 of the lactic acid bacteria and the sewage to the above sewage flow rate V<SB>1</SB>is set to 1/200-1/10. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
