某印染厂印染废水处理工艺设计毕业计算书

题目：某印染厂印染废水处理工艺设计

毕业设计中文摘要

印染行业是工业废水排放大户，据不完全统计，全国印染废水每天排放量为3×平原往事小说106～4×106m3。印染废水具有水量大、度高、成分复杂、有机物含量高、碱度大等特点，属难处理的工业废水。

设计规模：考虑到以后生产规模的扩大，设计处理能力为2000m3/d。

设计水质：根据企业提供的排水水质情况，设计进水水质为：pH8-9；COD1000mg/L；BOD 400mg/L；SS 300mg/L；度300mg/L；设计出水水质： PH6.0-9.0；COD≤180mg/L；BOD≤40mg/L；SS≤100mg/L，度≤80mg/L。FCI

本方案选用“水解酸化+SBR”工艺处理印染废水。水解酸化可以将废水中的难降解的大分子有机物分解成易降解的小分子有机物，提高可生化性。SBR池中高污泥活性、较高污泥浓度以及好氧、缺氧、厌氧状态交替出现的情况有利于难降解有机物的去除。因此，“采水解酸化+SBR”法处理生物难降解有毒有害印染废水。大足鼠耳蝠

Title Engineering design for printing and dyeing wastewater treatment plant

Abstract

Printing and dyeing industry wastewater emitters, according to incomplete statistics, the printing and dyeing wastewater every national emissions is 3×106 ~ 4×10深圳市长梁湘6m3.Printing and dyeing wastewater has the characteristics of large quantity, high chroma, complicated composition, high organic content, alkalinity, belongs to the industrial wastewater treatment.

Design: after taking into account the scale of the expansion of the scale of production, design, processing capacity of 2000m3/d.

Design: according to the water quality of drainage quality provided by the enterprise, the design influent quality as: pH8-9; COD 1000mg/L; BOD 400mg/L; SS 300mg/L;Chroma 300mg/L; Design : PH6.0-9.0; COD = 180mg/L; BOD = 40mg/L; SS ≤ 100mg/L ≤ 80mg/L, chroma.water quality: PH6.0-9.0; COD = 180mg/L; BOD = 40mg/L; SS ≤100mg/L ;chroma≤ 80mg/L.

The program selected the "treatment of printing and dyeing wastewater by hydrolytic acidification SBR process.Hydrolysis and acidification can decompose organic matter in waste water is difficult to be degraded into small molecules of easily biodegradable organic matter, increase biodegradability.In the SBR pool high sludge activity, high sludge concentration and aerobic,anoxic, anaerobic conditions appear alternately situation is conducive to the removal of refractory organic compounds.Therefore, by "hydrolysis acidification +SBR" method in the treatment of printing and dyeing wastewater degradation of toxic and harmful biological difficult.

Key words: printing and dyeing wastewater hydrolytic SBR
