Process Application Of Biological Aerated Filter

With modern industrial development and urban construction, environmental pollution in China's urban water pollution problem in particular is becoming increasingly serious. In dealing with water pollution in the area, the traditional wastewater treatment technology can be employed to discharge water quality requirements, in Water Pollution Control played a positive role. But these mature technology there are also some large investment in civil engineering, covers an area of great inconvenience, and other management shortcomings. Thus, the new sewage treatment technology has been research and development. Biological Aerated Filter (BAF) is on this basis to develop a traditional approach to overcome the inadequacies of the new technology representatives.Biological Aerated Filter law as a new sewage treatment technology, both at home and abroad have a practical application. Operating experience shows that the use of the technology can significantly reduce the savings and covers an area of investment in infrastructure, better water quality, running low-cost, easy management, in particular its modular structure conducive to future expansion. The process can operate independently, or with other sewage treatment process with applications, is a traditional alternative sewage treatment process, the more suitable for China's national conditions of the new sewage treatment method.This paper also through the design of the case, from a technical and economic aspects of the Biological Aerated Filter on the financial viability. In the same conditions (for water and access to water the same), BAF technology in the land, maintenance and management, water treatment, the degree of automation than traditional technology such as a greater advantage. In social benefits and environmental benefits, the use of the BAF for urban sewage discharge standards, produced by the social benefits and environmental benefits are incalculable, should be vigorously promoted.
