Abstract
Description
technical field
[0001] The invention relates to a sewage treatment process, a control device and a method, in particular to a sewage biological denitrification process, a control device and a method. Background technique
[0002] The SBR method is the abbreviation of the intermittent activated sludge water treatment method. Its treatment device is connected to the water inlet pipe, the outlet pipe and the sludge discharge pipe by the SBR reaction tank. There is only one reaction tank and the floor area is small. It is a conventional activated sewage Mud wastewater treatment process. However, due to incomplete nitrification in this activated sludge process, denitrification hardly occurs, and the removal rate of total nitrogen is only between 10% and 30%. For urban sewage and nitrogen-containing industrial wastewater, if the conventional activated sludge method is used for treatment, the effluent also contains a large amount of nitrogen and phosphorus, and the phenomenon of "...
