“生态活水”治理黑臭水体的研究
Study on Purification of Black and Odor Sewage by “Ecological Live Water”

为探索黑臭水体可持续治理途径，江苏农环生态环境工程有限公司联合扬州市水利学会，在扬州官河进行了“生态活水”治理黑臭水体试验。该试验运用“活水”和“氧债”理论，通过活水机与增氧机制造全方位流水，使用好氧、喜光和兼性等三类微生态制剂，加量使用强氧化性生化制剂，使黑臭水体快速复氧并迅速恢复生态系统，快速形成污水自我净化能力。仅用3天便造就“绿水”(生态活水)生态系统，氨氮等污染物被快速降解，并长久维持“绿水”生态系统，保持强大的污水净化能力。“‘生态活水’治理黑臭水体”技术是在原位(原有水体)就地处理黑臭水体，减少污水输送管道和污水处理厂设备投资，利用水体生态系统自净能力处理污水，具有设备投资省、治污速度快、运行成本低、可持续性强等特点，为城乡生活污水治理开辟了节能降耗的可行途径。
In order to explore the sustainable treatment of black and odorous water, Yangzhou Yanghuan Equipment Co., Ltd. and Yangzhou Water Conservancy Society jointly carried out the “ecological living water” treatment experiment of black and odorous water. In this experiment, the theory of “living water” and “oxygen debt” was used to prepare all-round flowing water through mixer and aerator. Using aerobic, light-loving and facultative micro-ecological agents and adding strong oxi-dation biochemical agents, the black and odorous water body is rapidly reoxygenated, the ecosys-tem is restored, and the self-purification ability of sewage is rapidly formed. It takes only three days to establish the “green water” (ecological living water) ecosystem, and quickly degrade ammonia nitrogen and other pollutants, and maintain the “green water” ecosystem for a long time to maintain a strong sewage purification capacity. The “ecological living water” technology is to treat black and odorous water in situ (raw water), reduce investment in sewage pipelines and sewage treatment plant equipment, and utilize the self-purification capacity of water ecosystem to treat sewage. It has the characteristics of low equipment investment, fast pollution control, low operation cost and strong sustainability. It opens up a feasible way to save energy and reduce consumption for urban and rural domestic sewage purification.
