| titleOfInvention | Treatment of waste water of slaughter house |
| abstract | PURPOSE: To eliminate the coloring occuring in the blood, etc. in waste water with a simple device by adding calcium oxide or slaked lime to the slaughterhouse waste water removed of coarse solids and separating the formed solids then subjecting the same to biological purification. n CONSTITUTION: Calcium oxide or slaked lime is added to the slaughterhouse waste water removed of coarse solids to allow the solids bound with the polluting components in the water to form, then said solids are separated off by a gravity sedimentation method, and a solid-liquid separation method. Thence, said separated liquid is subjected to biological purification treatment such as an activated sludge method, a rotary filter bed method, a water spray filter bed method, etc., whereby the colorless treated water is obtained. The amount of addition of calcium oxide or slaked lime can be varied over a wide range depending upon the quality of the waste water to be treated. The solid-liquid separation is much easier if they are added sufficiently in a manner as to leave undissolved components. n COPYRIGHT: (C)1981,JPO&Japio |
