某小城镇1000m3/d污水处理工程设计摘要:该毕业设计的题目为小城镇1000m3/d污水处理工程设计,应用的处理工艺为一体式氧化沟工艺,具有脱氮除磷的效果。进水水质CODcr=280mg/L,BOD5=100mg/L,SS=120mg/L,NH3=35mg/L,TP=5mg/L,出水水质CODcr小于5mg/L,BOD5小于5mg/L,NH3-N不超过5mg/L,TP不超过0.5mg/L,达到污水排放一级A标准。
该污水厂的大致处理流程为:原进污水经过粗、细格栅的处理流入调节池,经处理后再进入一体式氧化沟,然后进入消毒池,最后出水;从氧化沟中排出的污泥则输送到污泥浓缩池进行处理,最后外运处置。32348 毕业论文关键词: 一体式氧化沟工艺 脱氮除磷 污水处理
The Design of 1000m3 / d Small Town Sewage Treatment Work
Abstract:The graduate design topics for 1000m3 / d small town sewage treatment works desgin,application processing technology as one oxidation ditch process, with the effect of nitrogen and phosphorus removal. Water quality for CODCr = 280mg / L, BOD5 = 100mg / L, SS = 120mg / L,NH3-N = 35mg / L, TP = 3 mg / L,the effluent quality of CODCr≤10mg / L, BOD5≤10mg / L, SS≤10mg / L, NH3-N≤5mg / L, TP=0.5mg /L, reached an A wastewater discharge standards.
The sewage treatment process: roughly treated sewage into the original coarse, fine grid into the regulation pool, after processing into an integrated oxidation ditch, and then into the pool disinfection, the final effluent discharged from; oxidation ditch sludge is transported to the concentrated sludge thickening tank, final disposal.
Keywords: Integrated oxidation ditch process Nutrient Removal Sewage
