废水处理厂设计规模2000m3/d设计水质水量为Q=2000m3/d,BOD5=230mg/L
CODcr=1100mg/L PH=911SS=210 ㎎/l ,色度400倍。经处理后应达到下列出水水
质BOD≤25mg/L,COD≤100mg/L色度≤40倍SS≤70mg/L,PH=69。
本设计采用水解酸化加生物接触氧化处理废水。处理构筑物主要有调节池、水解酸
化池、生物接触氧化池、竖流式沉淀池、浓缩池、泵房、脱水机房和鼓风机房等。其主
要构筑物生物接触氧化池采用传统的一段式接触氧化总共采用两座每座分为四格
处理效果明显。预处理的调节池和水解酸化池有效的降低了污水的各项指标为生物接

II Abstract
The designing scale of waste water treatment plant is 2000 m3/d, the designing quality
and quantity of water are: Q=2000m3/d BOD5=230mg/L, CODcr=1100mg/L ,PH=9
11 ,SS=210 ㎎/l ,Color degree=400times. After disposing of it, the quality of water should
attain the following standards: BOD≤25mg/L,COD≤100mg/LSS≤70mg/LChroma ≤ 40
timesPH=69。
The design acid hydrolysis Biological oxidation wastewater treatment. Dealing with the
main structures regulation pool, pool acid hydrolysis, biological oxidation pond, the vertical
flow sedimentation tank, concentrated pool, pumping stations, Dehydration room and the
other blower. The main structures of biological oxidation pond used for the traditional
contact-oxidation, using a total of two, each divided into four blocks. significant treatment
effect. Pretreatment Regulation pools and pool acid hydrolysis effectively reduce the sewage
indicators of biological oxidation pond inundated. Intake provides the best indicator, but also
effectively reduce sewage color, plus behind the vertical flow sedimentation tank of
ulation and sedimentation, color indicators greatly reduced. Basically meet water
requirements. KEY WORDS: textile printing and dyeing wastewater
Keywords : dyeing wastewater wastewater treatment biological oxidation
