摘要:
污水处理厂去除氮磷污染物时往往需要投加外碳源，而现有外碳源来自石油类物质的生物炼制过程而导致成本较高，同时，为了满足“碳减排”与“碳中和”的战略需求，亟须开发新型碳源以代替现有碳源。蓝藻作为一种农业剩余物，含有丰富的有机质，在制备碳源方面具有较大潜力。简述了目前蓝藻制备生物质碳源的两类方法：厌氧消化法和物理化学法，主要介绍了利用蓝藻制备生物质碳源的难点，包括蓝藻脱水与浓缩，以及脱氮除磷和藻毒素的去除，同时归纳了可能的解决方法。最后结合已有蓝藻生物质碳源的研究，针对蓝藻生物质碳源可能存在的藻毒素抑制反硝化菌的问题，对解决措施（在蓝藻制备生物质碳源阶段采用酸水解工艺去除藻毒素，在投加蓝藻生物质碳源阶段逐步驯化耐受藻毒素的反硝化菌以高效去除总氮）进行了展望。
Abstract:
The removal of nitrogen and phosphorus pollutants in wastewater treatment plants (WWTPs) often requires the addition of external carbon sources, while the existing external carbon sources are derived from the biorefinery process of petroleum substances, resulting in high costs. In order to meet the strategic demand for carbon emission reduction and carbon neutralization, it is urgent to develop new carbon sources to replace the existing carbon sources. As an agricultural residue, cyanobacteria are rich in organic matter and have great potential for preparing carbon sources. In this paper, two methods for preparing biomass carbon source using cyanobacteria are briefly introduced: anaerobic digestion and physical-chemical methods. The difficulties in preparing biomass carbon sources using cyanobacteria are clarified, including the water removal for thickening, and the removal of nitrogen, phosphorus, and microcystins in cyanobacteria. Possible solutions to these difficulties are further summarized. Finally, combined with the existing research of cyanobacteria biomass carbon sources, the paper provides an outlook on current strategies to address the issue of potential inhibition of denitrifying bacteria by microcystins. These measures include： ①employing an acid hydrolysis process to remove microcystins during preparation stage of cyanobacterial biomass carbon sources; ②gradually domesticating denitrifying bacteria tolerant to microcystins during the dosing phase of cyanobacterial biomass carbon sources to achieve efficient total nitrogen removal.
