Sludge concentration and conditioning device and method for treating sludge using the same

Abstract

The present invention relates to a sludge concentration and conditioning device, and a method for treating sludge by using the same. To be specific, there is provided a sludge concentration and conditioning device, comprising: a storage device used for receiving and accommodating sludge and including a body and a cover, the body being provided with a sludge outlet and an overflow port, and the cover including a gas outlet for discharging gas; a filtering device disposed between the sludge outlet and the overflow port and used for filtering the sludge so as to achieve solid-liquid separation; a sludge feed device used for conveying sludge from below the filtering device into the storage device; an additive feed device used for conveying an additive from below the filtering device into the storage device; a sludge discharging device connected to the sludge outlet and used for discharging concentrated and conditioned sludge; and a concentrated sludge adjusting device including an adjusting tank in fluid communication with and surrounding the storage device, and used for adjusting the amount of concentrated sludge in the storage device according to the conditioning requirements. The present invention also provides a method for treating sludge by using the sludge concentration and conditioning device.
