Abstract:
Aiming at the problems such as high concentration of organic matter, high toxicity, and refractory of acetoacetanilide production wastewater, the pretreatment method of resin adsorption was used to study the actual wastewater from a biochemical plant. The results show that this method can effectively recover the acetoacetanilide products in the wastewater, while the COD of treated wastewater is less than 8 000 mg/L and its B/C ratio can reach more than 0.4. According to the optimized operating conditions established in the experiment, the treatment efficiency of COD is stable at 50% to 60%, and the recovery rate of acetoacetanilide is greater than 95%in the actual wastewater pretreatment project with 150 m3/d capability, which greatly improves the biodegradability of wastewater and doesnot basically affect the subsequent biological treatment process. There is a surplus after deducting operation costs for the recovered acetoacetanilide value of unit wastewater.
