农村生活与生产综合污水生物处理的A/O工艺启动策略与特性研究

Start-up strategy and performance of A/O process for the biotreatment of domestic and industrial wastewater in rural areas

为实现新时期各类典型性农村综合污水的治理,选择了一种农村生活与生产综合污水作为研究对象,研究了利用兼氧/好氧(A/O)工艺处理农村生活和生产综合污水的启动过程。结果表明:采用逐步递增生产废水和污泥接种培养的启动策略能够实现处理工艺的快速启动;pH、化学需氧量(COD)、氨氮(NH_(4)^(+)−N)、总磷(TP)以及色度在启动过程中各阶段的变化情况的分析结果表明,A/O工艺能够通过兼氧池和好氧池的协同配合达到理想的污水处理效果。

In order to realize the treatment of various typical rural composite sewage in the new era,domestic and industrial wastewater in rural areas was selected as the research object in this paper.The start-up of anoxic/oxic(A/O)process for domestic and industrial wastewater treatment in rural areas was investigated.The results show that rapid start-up of the process can be achieved via the strategy such as increasing ratio of industrial wastewater and sludge inoculation culture.Changes of pH value,COD,NH_(4)^(+)-N,TP,and chroma in each stage during start-up show that perfect performance of A/O process can be achieved through the cooperation of facultative tank and aerobic tank.
