Example of Organic Silicone Production Wastewater Treatment Engineering
With the rapid development of the new material industry,the water pollution problem caused by the silicone enterprises in the production process needs to be solved urgently.This paper takes a new material production enterprise in Zhejiang province as an example.The production wastewater contains oil,and has the characteristics of high salt,high COD,high SS and low biochemistry.The engineering design adopts the combined process of"primary coagulation+anaerobic folding plate reactor(ABR)+A/O+Fenton advanced oxidation method+secondary coagulation+sodium hypochlorite catalytic oxidation method".The influence of quantity,reaction pH and hydraulic residence time on the treatment effect was studied in detail.Through small test and pilot test,the application of this design process can meet the direct discharge standard in the standard(GB 31572-2015)and(GB 31571-2015).The commissioning results of the sewage station show that the actual treatment effect can reach the first-level discharge standard in the comprehensive sewage discharge standard(GB 8978-1996).
