Description

Assembly drum type wastewater drying device {Assembly drum type wastewater drying device}

The present invention relates to a non-degradable or concentrated wastewater treatment apparatus, and to an assembled drum-type wastewater dryer capable of adjusting the number of drums installed in the transverse and longitudinal directions in an assembled form, thereby adjusting the wastewater treatment capacity.

Recently, with the advancement of industry and the expansion of industrial scale, the concentration and composition of industrial wastewater and sludge discharged from various workplaces are diversifying, and the amount of discharge is continuously increasing.

In particular, unlike domestic wastewater, industrial wastewater contains a large amount of oil and organic substances, and as high-concentration non-decomposable wastewater, which is difficult to decompose the contained substances, it brings tremendous harm by destroying the natural ecosystem.

In the treatment of high-concentration, non-degradable wastewater in which various organic substances, chemicals, and heavy metals are mixed, additional biological treatment is performed after physical and chemical treatment worldwide.

Until now, the technology has not been able to achieve a satisfactory treatment level in the treatment of such non-degradable specific wastewater, so the development of a treatment method is urgently required.

In addition, it is difficult to treat sludge along with wastewater, so treatment measures are needed together.

Accordingly, a wastewater drying device using a drum has been proposed, but in the case of a conventional drum dryer, the contact area between the heated part of the drum and the wastewater is limited to a certain portion, resulting in poor drying efficiency and poor heat exchange. Otherwise, there was a problem in that the drying device had to be large.
