The invention claimed is: 1. Settling basin membrane (1) made of polymer material, which is gas-permeable by means of a perforation (2), whereby with regard to permanent gas permeability of the polymer material, an inhibitor that is biologically active for waste water is added to the polymer material, which inhibitor is difficult to dissolve in water, and is distributed in the polymer material in essentially uniform manner, wherein the inhibitor is an inhibitor system, formed by a microorganism inhibitor and an algae inhibitor, whereby in reference to the total mass of the polymer material, the proportion of the inhibitor system is 0.1 to 5.0 wt.-%; and that the polymer material is a vulcanized rubber mixture, specifically on the basis of an ethylene-propylene-diene mixed polymerizate (EPDM), of nitrile rubber (NBR), or silicone rubber, each of them uncut, or on the basis of an EPDM/NBR blend, whereby with reference to the total mass of the polymer material, the proportion of the polymer or rubber or blend component is 10 to 50 wt.-%. 2. Settling basin membrane according to claim 1, wherein the inhibitor, particularly as a microorganism inhibitor, is 2,4,4'-trichloro-2'-hydroxy-diphenyl ether. 3. Settling basin membrane according to claim 1, wherein the inhibitor, particularly as an algae inhibitor, is N'-tert. butyl-N-cyclopropyl-6-(methylthio)-1,3,5-triazine-2,4-diamine. 4. Settling basin membrane according to claim 1, wherein a carrier material that is charged with the inhibitor or inhibitor system is mixed into the polymer material, specifically with the formation of a corresponding adduct. 5. Settling basin membrane according to claim 4, wherein the carrier material is a molecular screen, preferably on the basis of a sodium-aluminum silicate. 6. Settling basin membrane according to claim 1, wherein the polymer material is free of plasticizer. 7. Settling basin membrane according to claim 1, wherein it is configured as a plate membrane. 8. Settling basin membrane according to claim 1, wherein it is configured as a tube membrane. 9. Settling basin membrane according to claim 1, wherein it is configured as a plate aerator membrane.
