COD= %,ηSS= %,色度 95%。经技术经济分析,此方案投资总额 869 万元,废水处理成本为 元/m 3。关键词:纺织印染废水混凝水解酸化接触氧化购买后包含有 CAD 图纸和说明书,咨询 Q401339828 印染废水处理课程设计说明书 2 Abstract The designing scale of waste water treatment plant is3000 m 3 /d, the designing quality and quantity of water are: Q=3000m 3 /d, COD=700 ~ 1000mg/L ,PH= ~10 ,SS=500 ~800 ㎎/l ,Color degree=400 ~600 times. After disposing of it, the quality of water should attain the following standards: COD ≤ 60mg/L , SS ≤ 30mg/L , Chroma ≤30 times , reaching the B standard of ( DB37/533-2005 )of local standards of Shandong Province Textile industrial water pollutant discharge standards. The design of this project is in accordance with requirements of the environmental protection in the wastewater. It uses the coagulation- sedimentation -hydrolytic acidification – contact oxidation process to deal with the wastewater in textile printing. Based parison of the detailed program, we select the following processes: Printing and dyeing wastewater R egulating pond G rids Coagulation sedimentation tanks Hydrolytic acidification Contact oxidation pond Secondary sedimentation tank Drainage Pool enrichment Dehydrate Sludge Carry out Sludge Through designing, we can know that the result of? COD is 94%, η SS is %,color degree is 95%. 购买后包含有 CAD 图纸和说明书,咨询 Q401339828 印染废水处理课程设计说明书 3 After technical and economic analyzing, the investment amount of this project is Yuan, and the cost of disposal of waste water Yuan / t. Itnot only gains good economic and social benefits,
