| titleOfInvention | A kind of processing method of bone gelatin waste water |
| abstract | The present invention relates to technical field of waste water processing, there is provided a kind of processing method of bone gelatin waste water, comprises the following steps：The waste liquid that skeletal grain is treated in acid dip tank is discharged into reactive tank, milk of lime is then added into reactive tank, separation of solid and liquid then will be carried out and obtains the first filtrate and the first sediment；Filtrate is discharged into displacement slot and enters line replacement reaction, the concentrated sulfuric acid is then added into displacement slot and is stirred, the second filtrate and the second sediment are obtained through separation of solid and liquid；The some or all of return acid dip tank of second filtrate is recycled；Wherein, the mass fraction of milk of lime is 12 18%, and the dosage of milk of lime is the 10 15% of waste liquid quality；The mass fraction of the concentrated sulfuric acid is 70 98%, and the dosage of the concentrated sulfuric acid is the 5 10% of waste liquid quality.The Ca in waste liquid caused by pickling can be removed 2+ , while waste liquid can also recycle after treatment, and cost is lower, is advantageous to environmental protection. |
