1、 I 摘 要 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

2、酸化池有效的降低了污水的各项指标，为生物接触氧化池的进水，提供了最佳进水指标，同时还有效的降低了污水的色度，再加上后面的竖流式沉淀池的絮凝沉淀作用，色度指标大大降低，基本上可以满足出水的要求。 关键 词 ：印染废水 废水处理 生物接触氧化 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=911 ,SS=

3、210 /l ,Color degree=400times. After disposing of it, the quality of water should attain the following standards: BOD25mg/L,COD100mg/L， SS70mg/L， Chroma 40 times， PH=6 9。 The design acid hydrolysis Biological oxidation wastewater treatment. Dealing with the main structures regulation pool, pool acid

4、 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.

5、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 flocculation and sedimentation, color indicators greatly reduced. Basically meet water requirements. KEY WORDS: textile printing and dyeing wastewater Keywords : dyeing wastewater wastewater treatment biological oxidation
