Fixed microbial contact material for wastewater treatment and wastewater treatment device using the same

摘要

The present invention relates to a microorganism contact material that can be used as an auxiliary means for maintaining a certain level of cells in an aeration tank or a high-efficiency wastewater treatment apparatus using a bioreactor in a biological treatment process for wastewater treatment, and supports a pillar. , And a contact phase composed of a contact yarn arranged in both directions along the support yarn and an auxiliary yarn of 10 to 500 parts by weight based on the weight of the contact yarn.;This is because the manufacturing cost is low and the aerobic property of the support part is very high, so that the conventional microbial contact material is difficult to contact the cells inside the contact material and the anaerobic performance can be significantly improved, and the wastewater treatment device is used for the wastewater treatment device. When passed through, the biofilm formed on the surface of the contact material can biologically oxidize and decompose contaminants in the waste water.
