To provide a sheet laminate used in a wastewater treatment apparatus that purifies wastewater by using the action of microorganisms contained in or retained on a surface of the wastewater, and can maintain the purification performance of the wastewater treatment apparatus.SOLUTION: A sheet laminate 21 includes a base material 211 and a gas-permeable non-porous layer 212 wherein the base material 211 is a microporous membrane. The sheet laminate 21 further includes a microbial support layer 213. The gas-permeable non-porous layer 212 has adhesiveness. The microbial support layer 213, the gas-permeable non-porous layer 212, and the base material 211 are laminated in this order from a side that comes into contact with wastewater. The microbial support layer 213 is formed on a surface of the gas-permeable non-porous layer 212 having adhesiveness that comes into contact with wastewater.SELECTED DRAWING: Figure 4 【課題】廃水に含まれるか、もしくはその表面に保持されている微生物の働きを利用して廃水を浄化する廃水処理装置に用いられるシート積層体であって、廃水処理装置の浄化性能を維持可能なシート積層体を提供する。【解決手段】シート積層体２１であって、基材２１１と、気体透過性無孔層２１２とを含み、前記基材２１１が微多孔膜であり、前記シート積層体２１がさらに微生物支持層２１３を含み、前記気体透過性無孔層２１２が粘着性を有し、廃水に接する側から、前記微生物支持層２１３、前記気体透過性無孔層２１２、前記基材２１１の順に積層されており、粘着性を有する前記気体透過性無孔層２１２の廃水に接する面が前記微生物支持層２１３である構成とする。【選択図】図４
