中文摘要:
      利用藻菌共生系统处理废水是一项高效的资源化技术,但该系统对废水的处理受到许多因素的影响。本研究筛选到4株可在猪粪废水中生长的芽孢杆菌,分别与莱茵衣藻(Chlamydomonas reinhardtii)构建共生系统,通过对水质的测定,研究了藻菌共生系统产生协同作用高效率转化猪粪废水的条件。结果表明,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;在添加0.5 g/L葡萄糖后,藻菌共生系统对废水的营养物质的去除效率均得到显著提升,其中Bacillus.coagulans BS32和Chlamydomonas reinhardtii组成的共生系统的去除效率提高最为明显;氨氮、总氮、总磷和COD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 μM丙氨酸后,藻菌共生系统对猪粪废水的去除效率均进一步得到提高,其中,B.coagulans BS32和C.reinhardtii组成的共生系统与纯藻系统相比,对氨氮、总氮、总磷和COD的去除效率分别提高了18.16%、39.51%、19.84%和39.56%,表明添加少量葡萄糖和微量丙氨酸可以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:
      The symbiosis system of algal - bacterial is a resourceful technology for efficient treatment of wastewater, but the treatment effiency is affected by many factors. In this study, four strains of Bacillus sp. which can be grown in pig manure wastewater were screened. Four symbiosis systems of algal-bacterial were constructed with Bacillus sp. and Chlamydomonas reinhardtii respectively and explored the conditions for efficiently transform pig manure wastewater by the determination of water quality. The results showed that the four symbiosis systems did not show an advantage in the treatment of pig manure wastewater compared with the pure algae system. After the addition of 0.5 g/L glucose, the removal efficiency of wastewater was improved significantly,in which consisting of B.coagulans BS32 and C. reinhardtii has the most significant increase. The removal efficiencies of ammonia nitrogen, total nitrogen, total phosphorus and COD increased by 16.58%, 28.38%, 8.90%, and 23.04% respectively compared with pure algae system. After adding 100 μM alanine as spore germinator into the symbiosis systems with 0.5 g/L glucose, the removal efficiency was further significantly improved. The removal efficiencies of ammonia nitrogen, total nitrogen, total phosphorus, and COD increased by 18.16%, 39.51%, 19.84%, and 39.56% in the symbiosis system of B.coagulans BS32 and C. reinhardtii compared to the pure algae system. It indicated that the addition of a small amount of glucose and trace amounts of alanine can enhance the effective transformation of pig manure wastewater with the algal-bacterial symbiosis systems.
