The invention discloses an aeration device and an aeration method. The aeration device includes a bubble shear diffuser and an airflow slow release device. The airflow slow release device includes an installation part and an airflow slow release part fixed at the lower end of the installation part; The slow-release part has a first slow-release space and a second slow-release space surrounding the first slow-release space; the mounting piece is used to install the air distribution pipe; the air outlet of the air distribution pipe is set downward, the air outlet of the air distribution pipe, the first slow-release The space and the second slow-release space are sequentially communicated; the airflow slow-release part has a first airflow channel for the airflow to escape from the first slow-release space to the second slow-release space, and for the airflow to escape from the second slow-release space the second airflow channel. For the first time, the present invention adopts the downward flow from the mouth of the gas distribution pipe to design the airflow slow-release device, which can not only realize uniform aeration, but also solve the problem of water inflow into the gas distribution pipe network caused by the upward flow out of the mouth of the gas distribution pipe, which leads to aeration failure.
Description
technical field [0001] The invention belongs to the technical field of sewage and wastewater aeration equipment, and in particular relates to an aeration device and an aeration method. Background technique [0002] The aerator is an essential equipment for drainage aeration and oxygenation, and a sharp tool to improve the activity of aerobic microorganisms in sewage. In sewage treatment, the quality of aerator equipment and the quality of its operation directly affect the efficiency and operating costs of sewage treatment, and even affect the success or failure of the entire sewage treatment system. [0003] At present, the commonly used aeration technology adopts microporous aerators, which use the idea of small hole interception to perform aeration. The size of the opening and closing of the orifice diaphragm determines the size of the bubbles. The smaller the bubbles in the water , the larger the contact area with water, the higher the efficiency of oxygen transfer per...
