Description
技术领域technical field
本发明属于环境保护中污水处理技术领域，具体涉及一种强化曝气生态修复装置。The invention belongs to the technical field of sewage treatment in environmental protection, and in particular relates to an enhanced aeration ecological restoration device.
背景技术Background technique
曝气复氧是通过人工控制的方法向水体中充氧来恢复水体环境生态功能的一种措施。上世纪60年代起，人工曝气强化技术就被应用于河道治理。国内外的运行表明，在污染河道中进行人工曝气复氧能改变污染水体感官的黑臭状况，使河道上层底泥中还原性物质被氧化降解。曝气能在河道形成一个以好氧菌为主的生态环境，从而能在较短时间内降低水体中有机污染物，提高水体DO，增强水体的自净作用，使水体水质得到有效改善。Aeration and re-oxygenation is a measure to restore the ecological function of the water body environment by artificially controlling the method of oxygenating the water body. Since the 1960s, artificial aeration enhancement technology has been applied to river management. Operations at home and abroad have shown that artificial aeration and reoxygenation in polluted rivers can change the black and odorous state of the polluted water body, and cause the reducing substances in the upper sediment of the river to be oxidized and degraded. Aeration can form an ecological environment dominated by aerobic bacteria in the river channel, thereby reducing organic pollutants in the water body in a short period of time, increasing DO in the water body, enhancing the self-purification effect of the water body, and effectively improving the water quality.
传统的曝气方式大多采用鼓风曝气，其结构简单，安装方便，但是，曝气性能较差，曝气设备一般安装在水底，污水的底部沉淀有大量的污泥和颗粒沉淀，不仅容易堵塞曝气口，还使得气体不能均匀地与污泥、污水进行接触，降低了处理效果；而且曝气设备能耗较高，曝气充氧的电耗一般占污水处理厂总能耗的50％以上，导致系统在长期运行时运行和维护费用较高，这也是许多已建污水处理厂难以维持正常运行的原因。Most of the traditional aeration methods use blower aeration, which has a simple structure and is easy to install. However, the aeration performance is poor. The aeration equipment is generally installed at the bottom of the water, and a large amount of sludge and particles are deposited at the bottom of the sewage, which is not only easy to Blocking the aeration port also makes the gas not evenly contact with the sludge and sewage, which reduces the treatment effect; moreover, the energy consumption of the aeration equipment is high, and the power consumption of aeration and oxygenation generally accounts for 50% of the total energy consumption of the sewage treatment plant. More than %, resulting in high operating and maintenance costs of the system during long-term operation, which is also the reason why many established sewage treatment plants are difficult to maintain normal operation.
