The heavy metal ion such as copper and zinc ions must be removed preferentially through pretreatment process. pH adjustment and flocculation 北京理工大学珠海学院 XXXX 届本科生毕业设计sedimentation were designed to transform the copper ion and zinc ion to iron hydroxide, copper hydroxide and zinc hydroxide to be precipitated and removed. SBR（sequencing batch reactor）is adopted to treat the effluent. COD is biodegraded and ammonia is nitrified through biochemical treatment process in SBR reactor. Effluent is discharged after sand filtration and advanced oxidation treatment to meet the class I standard of water pollution discharge limit (DB44 / 26-2001) of Guangdong Province.Keywords: Metal processing wastewater; heavy metal ion removal; SBR; sequencing batch activated sludge process 目 录1 前言....................................................11.1 本设计的目的、意义及应达到的技术要求.....................11.2 本设计在国内外的发展概况及存在的问题.....................11.3 本设计应解决的主要问题..................
