Abstract

The invention provides a two-stage automatic stirring sewage purifying tank with a denitrification function. The two-stage automatic stirring sewage purifying tank with the denitrification function comprises a horizontal cylindrical tank body, a water inlet tube, a return tube and a water outlet tube; and a cavity of the tank is divided into four cells which communicate with one another by three partitions. The two-stage automatic stirring sewage purifying tank with the denitrification function is characterized in that the return tube communicates with the first cell and the fourth cell; aerobic nitrification is carried out in the third cell to remove ammonia nitrogen in water; liquid in the fourth cell returns to the first cell by gas in the return tube in a steam stripping mode; and sewage is further treated by anaerobic denitrification reaction. According to the sewage purifying tank, the sewage is treated by aerobic nitrification in the third cell and anaerobic denitrification reaction in the first cell, the ammonia nitrogen and COD content in the sewage can be removed, an air pump is used as a unique power source, automatic stirring can be realized, the sewage treatment effect is good, energy consumption is low, the beneficial effects are remarkable, and therefore, the two-stage automatic stirring sewage purifying tank is suitable for treating sewage in the rural area in a dispersed manner.

Description

technical field [0001] The invention relates to an automatic stirring sewage purification tank, more specifically, to a two-stage automatic stirring sewage purification tank with denitrification function which is suitable for rural sewage dispersion treatment. Background technique [0002] Domestic sewage in most rural areas of our country is discharged without any treatment, causing the overall water quality of rivers in rural areas to deteriorate. Nutrients mainly nitrogen and phosphorus exceed the standard seriously, and some rivers and lakes have shown severe eutrophication. [0003] Compared with the mature urban sewage treatment, the treatment of rural sewage is a difficult problem in environmental governance. Urban sewage can be collected by the urban drainage pipe network and transported to sewage treatment plants for treatment, but the treatment of rural sewage cannot learn from the methods of urban sewage treatment. The rural areas of our country are scattered, an...
