What is the knowledge about integrated sewage treatment equipment?

There are many integrated equipments for sewage treatment, and the best one is the diversion biological aerated filter. According to the invention, sewage is aerated twice, precipitated twice and filtered twice in the same treatment tank, so that the process flow that other sewage treatment needs four tanks to complete is solved, especially under the condition of continuous water inflow, intermittent aeration and activated sludge backflow are realized, and the whole operation does not idle. Its advantages are more prominent than traditional treatment methods, and the treatment effect is particularly remarkable. In August 2009, it was listed as an "innovative project" by the Ministry of Science and Technology; In June 5438+February 2009, the product was listed in the Catalogue of Environmental Protection Technologies Encouraged by the State by the Ministry of Environmental Protection. 20 10 was recognized as "national key new product" by the Ministry of Science and Technology, the Ministry of Environmental Protection, the Ministry of Commerce and the General Administration of Quality Supervision, Inspection and Quarantine in May. 20 12 was listed as "environmental protection technology encouraged by the state" by the Ministry of Environmental Protection in July. Guided biological aerated filter (BAF) fully draws lessons from eight design methods, such as BAF method, contact oxidation method, biofilm method, intermittent aeration method, artificial rapid filtration method, precipitation separation method, nitrification and denitrification method, and water supply rapid filtration method, and develops a new sewage treatment process and technology. In 2005, it obtained the national patent with the patent number of ZL200420033672.4, and the diversion biological aerated filter has been used in Beijing, Shandong, Hebei, Guizhou, Shanxi, Sichuan, Inner Mongolia, Heilongjiang, Jiangsu, Jilin, Henan, Hubei, Tianjin, Xinjiang and other places in China, involving life, hospitals, chemical industry, slaughter, food, flax, alcohol and pharmacy. A large number of applications have proved that the CODcr of effluent quality is generally below 20mg/L, and the lowest is 5.95 mg/L; Generally, BOD5 is below 10mg/L, and the lowest is 3.50mg/L.: SS is generally below 20mg/L, and the lowest is 6.55 mg/l.
