Description

Disc drum filter for wastewater treatment {A DISK DRUM FILTER FOR DISPOSING A SLUDGE OR SEWAGE}

The present invention relates to a disc drum filter for treating waste water, and more particularly, to prevent the raw water from being discharged to the treated water in the process of being supplied to the drum, and at the same time, the drum stably without a single load or rotational imbalance. Disclosed is a disc drum filter for wastewater treatment.

As a result of pollution of rivers, rivers, or seas caused by pollutants contained in wastewater discharged from homes or factories, severe environmental problems that cause the death of aquatic organisms and destroy ecosystems such as algae or fish due to the accumulation of suspended solids. Occurred.

Accordingly, various methods for purifying contaminants of discharged wastewater have been proposed and used, and representatively, the wastewater is included in the wastewater by various methods such as precipitation, adsorption, ion exchange, neutralization, flocculation, flotation and reverse osmosis. The pollutants are removed and the treated water is recycled.

In this way, one of the facilities for treating waste water is a disk drum filter for supplying raw water containing contaminants to the rotating drum and then removing the contaminants by the filter means mounted on the drum to separate the treated water and sewage. Mainly used.

6A to 6C, the conventional general drum drum filter 100 has an inlet pipe 112 through which raw water containing contaminant is introduced from one side of the housing 110, and the contaminant is filtered. A discharge pipe 114 through which the discharge water is discharged is formed, and is supported by the lining prevention roll 122 on the inner surface of the housing in which the inflow pipe and the discharge pipe are formed, and is supported by the lining 124 at one end of the circumferential surface. The drum 120 is provided.
