Research Status and Prospect Of Micro-polluted Water Pretreatment With Biological Aerated Filter

Abstract

Abstract. Recently, with the rapid development of industry, the pollution of organic compounds and ammonia nitrogen is serious in source water. It is difficult to ensure the removal efficiency of ammonia nitrogen and organic compounds in effluent by conventional treatment technology. The article brings out the treatment of micro-polluted water by biological aerated filter. This article discuss the pre-treatment of micro-polluted water with biological aerated filter from following aspects:the principle of micro-polluted water's treatment by BAF, the advantages of pollutant removal ,and influencing factors of stable operation of BAF .In the end, this article introduces the practical application of the pre-treatment of micro-polluted water by biological aerated filter, and makes prospects for its development and application.
