The biggest feature of the synergistic catalytic oxidation method is that it can improve the biodegradability of wastewater, oxidize harmful substances in wastewater into CO2, H2O or mineral salts indiscriminately, and effectively decolorize, denitrify, remove phosphorus, chlorinate metals and refractory toxic organic substances without leaving any residue.
Guided biological aerated filter (BAF) is an innovative technology for intensive sewage treatment, which fully draws lessons from the design methods of anaerobic biological treatment methods such as SBR method, AO method, A2O method, oxidation ditch method, activated sludge method, biological filter, biological rotary table, biological contact oxidation and anaerobic digestion, hydrolytic acidification, UASB, and secondary or tertiary sewage treatment processes. In 2005, China National Intellectual Property Administration was approved as a national patent product with patent number ZL200420033672.4.
Conducted flow biofilter is the most advanced sewage treatment technology encouraged by the Ministry of Environmental Protection. In June 2009, it was listed as an "innovative project" by the Ministry of Science and Technology with the project code of 09C26215205564; . From June 5438 to February 2009, the Ministry of Environmental Protection listed this product in the Catalogue of Environmental Protection Technologies Encouraged by the State (UNCED [2009] 146); 20 10 in may, 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 identified the diversion biological aerated filter as a national key new product with the number of 20 10GR4670 10. In 20 12, the Ministry of Environmental Protection listed the product in the catalogue of environmental protection technologies encouraged by the state in 20 12. New technologies and new processes are innovative in technical methods and advanced in technical indicators, reaching the practical engineering application level. The state encourages project demonstration and vigorously promotes its application in pollution control projects.
