摘要:
针对乙酰乙酰苯胺生产废水有机物浓度高、毒性大、难降解等问题，以某生化厂实际废水为研究对象，采用树脂吸附的预处理方法对其进行试验研究。结果表明，这种方法能有效回收废水中的乙酰乙酰苯胺产品，同时处理后的废水COD＜8 000 mg/L，其B/C值可达0.4以上。按照试验中所建立的优化操作条件，在150 m3/d规模的实际废水预处理工程实践中，对COD的处理效率稳定在50%～60%，乙酰乙酰苯胺回收率＞95%，大大提高了废水的可生化性，对后续生物处理过程基本不构成影响。单位废水回收乙酰乙酰苯胺的价值，扣除运行成本还有盈余。
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.
