Biodegradation of iridium-containing organic wastewater and simulated wastewater by different strains was studied in this paper. By qualitative and quantitative analysis of each organic component in the wastewater and determination of the content of total organic carbon in the organic wastewater, the decomposition effect of microorganisms on organic materials in the iridium containing organic wastewater was discussed. The results showed that the decomposition effect of the combined bacteria was better. In the simulated wastewater system, the degradation rate of the three strains of LA-2, LB-1 and LZ-1 reached about 95%, and in the actual wastewater system, the degradation rate of the combination of LA-2 and LZ-1 reached about 49%. The results show that microorganisms can effectively degrade organic pollutants and are environmentally friendly, which proves the feasibility of biodegradation of organic matter in iridium-containing organic wastewater.
