中文摘要:
      目的:通过适应猪粪废水芽孢杆菌的筛选,以4株芽孢杆菌分别与莱茵衣藻(Chlamydomonas reinhardtii)构建共生系统.方法:通过对氨氮、总氮、总磷、化学需氧量的测定,研究藻菌共生系统产生协同作用高效率转化猪粪废水的条件.结果:与纯藻系统比较,4个藻菌共生系统对猪粪废水的处理并未表现出优势;但添加0.5 g/L葡萄糖后,4个藻菌共生系统的去除效率显著提升,Bacillus.coagulans BS32和C. reinhardtii的共生系统的去除效率提高最明显;氨氮、总氮、总磷和化学需氧量的去除效率分别提高了16.58%, 28.38%, 8.90%和23.04%.同时,添加0.5 g/L葡萄糖和芽孢萌发剂100 μmol/L丙氨酸后,藻菌共生系统对废水的去除效率进一步提高, B.coagulans BS32和C.reinhardtii的共生系统对氨氮、总氮、总磷和化学需氧量的去除效率分别提高了18.16%, 39.51%, 19.84%和39.56%.结论:添加少量葡萄糖和微量丙氨酸可促进莱茵衣藻和芽孢杆菌共生系统对猪粪废水的有效转化.
英文摘要:
      Objective: To construct a symbiotic system with four strains of Bacillus sp. and Chlamydomonas reinhardtii and screen Bacillus sp. grown in piggery wastewater. Method: Through the measurement of ammonia nitrogen, total nitrogen(TN), total phosphorus(TP), and chemical oxygen demand(COD), the conditions for efficient transformation of piggery wastewater by the symbiotic system of algal bacteria were studied. Results: The four-algal symbiosis systems showed no advantage in the treatment of piggery wastewater compared with the one-algae system. However, after the addition of 0.5 g/L glucose, the removal efficiency of the four-algal system improved significantly, with the B.coagulans BS32 and C. reinhardtii system increased most obviously. Compared with the pure algae system, the removal efficiency of ammonia nitrogen, TN, TP and COD increased by 16.58%, 28.38%, 8.90%, and 23.04% respectively. Additionally, after adding 100 μM alanine as spore germinator into the symbiosis systems with 0.5 g/L glucose, the removal efficiency of wastewater was further improved. The removal efficiencies of ammonia nitrogen, TN, TP, and COD increased by 18.16%, 39.51%, 19.84%, and 39.56% in the symbiosis system of B.coagulans BS32 and C. reinhardtii. It is shown that the addition of a small amount of glucose and trace amounts of alanine can enhance the effective transformation of piggery wastewater by the algal-bacterial symbiosis systems.
