After disposing of it, the quality of water should attain the following standards: COD≤100mg/L， SS≤50mg/L， Chroma ≤ 40 times， reaching the B standard of (DB37/5332020） 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 hydrolytic acidificationSBRcoagulationsedimentation process to deal with the wastewater in textile printing. Based on parison of the detailed program, we select the following processes: Printing and Regulating Hydrolytic SBR dyeing wastewater →Grids→ pond → acidification→pond ↓ Carry Dehydrate Pool Coagulation out Sludge← Sludge ←enrichment←sedimentation tanks→D rainage SS is %,color degree is %. After technical and economic analyzing, the investment amount of this project is million Yuan, and the cost of disposal of waste water is Yuan/ m3. It not only gains good economic and social benefits, but also fully puts the ideas of saving land economically, improving virescence and reducing energy consuming into the practice while designing, which is in conformity with new era environmental needs.
