A chemical enterprise in northwest China mainly produces 1, 4-butanediol, PTMEG and other chemical raw materials, with high concentration of waste water pollutants, low biochemical properties, strong biological toxicity and difficult to biodegrade. The pilot system constructed a chemical flocculation precipitation - heterogeneous catalytic oxidation-UASB-multistage aerobic-MBR system for treating BDO and PTMEG wastewater. The pilot system operates stably and efficiently, and the effluent meets the national sewage comprehensive discharge standard (GB8978-2002) grade A standard.
