Description

Technical Field

[0001] This utility model relates to the field of DTRO membrane technology, specifically a DTRO composite membrane installation structure. Background Technology

[0002] DTRO membrane is a membrane module technology used for the treatment of high-concentration industrial wastewater. Its core technology lies in its ability to directly treat high-concentration wastewater without pretreatment.

[0003] The DTRO membrane mainly consists of a membrane shell, upper flange, tie rod, guide vanes, DTRO membrane sheets, and lower flange. The columnar structure formed by the alternating stacking of guide vanes and DTRO membrane sheets is fitted onto the tie rod. During operation, after the wastewater passes through the columnar wastewater treatment structure formed by the guide vanes and DTRO membrane sheets, the separated clean water flows out through the gap between the tie rod, guide vanes, and DTRO membrane sheets. Because this gap is small, the separated clean water cannot flow out quickly, ultimately causing a decrease in the water production efficiency of the DTRO membrane. Utility Model Content
