摘要：

为探讨光合细菌在废水处理和协同固碳作用中应用的可行性，利用红假单胞菌处理废水，研究其在处理时间120 h内对废水的化学需氧量（COD）的去除能力，并在处理过程中通过通入CO₂研究红假单胞菌对废水处理与协同固碳的能力。结果显示：红假单胞菌在有氧有光条件下，光合微生物处理效果最佳，400 mL模拟废水中添加的红假单胞菌浓度为0.5 g/L，处理120 h，废水COD值由2 753.50 mg/L降低至185.57 mg/L。红假单胞菌不仅能有效处理废水，显著降低废水COD值，同时能实现对CO₂的固定。

Abstract:

In order to explore the feasibility of the application of photosynthetic bacteria in wastewater treatment and collaborative carbon sequestration, Rhodopseudomonas palustris was used to treat wastewater, and its ability to remove chemical oxygen demand(COD) of wastewater within 120 h of treatment time was studied. CO₂ was introduced into the treatment process to study rhodopseudomonas' ability to treat wastewater and collaborative carbon sequestration. The results showed that the photosynthetic microorganisms had the best treatment effect under the condition of aerobic light. The concentration of rhodopseudomonas added to 400 mL simulated wastewater was 0.5 g/L. After treatment for 120 h, the COD value of wastewater decreased from 2 753.50 mg/L to 185.57 mg/L. Rhodopseudomonas can not only effectively treat wastewater as well as significantly reduce the COD value of wastewater, but also achieve the fixation of CO₂.

Key words: photosynthetic bacteria, CO₂ absorption rate, organic carbon utilization, coprocessing
