BAS Municipal Wastewater Advanced Treatment Process

Abstract:

BAS (Biochemical Adsorption Separation) process is a kind of municipal wastewater advanced treatment process which could treat municipal wastewater directly to meet the Ⅳ class of surface water standard. BAS process integrated by 4 technologies: (1) high elastic cilia filler biochemical treatment technology, (2) effluent from the facultative oxygen zone technology, (3) AZ - 01 ammonia nitrogen adsorption technology and (4) active ceramic filtration technology. The effluent quality of BAS process could reach COD_Cr≤30mg/L, BOD₅≤6mg/L, TP≤0.3mg/L, TN≤1.5mg/L and SS≤1.5mg/L. BAS process has the advantages of easy operation, stable treatment effect, little construction and low operation cost. It is suitable use in our country special sensitive area such as Tai Lake, Dian Chi, etc. and some area which requires higher water quality.
