超声波协同H_2O_2处理养殖场污水

为了有效地改善养猪场污水的质量,以H2O2为药剂,对污水进行了水浴加热和超声波辅助的对比实验,考察了超声波发生器输出端电流强度、处理时间、H2O2用量对污水的COD、氨气及颜色的影响,并进行正交实验优化。结果表明,超声波协同H2O2处理养殖污水是一种切实可行的方法,超声波协同H2O2处理污水的最佳工艺条件:电流0.7 A、处理时间2 min、H2O2用量3%,在此条件下降低COD量可达95%以上,氨氮的含量可降至14~15 mg/L,氨臭味大大得到了改善,并将原污水由黑色变为浅黄色。

Synergetic treatment of culture sewage by ultrasonic and H2O2

In order to improve the sewage quality from piggery effectively, the sewage was executed by the contrasting experiment of water-bath heating and ultrasonic synergism with H₂O₂ as agent. It is investigated that the ultrasonic generator output current intensity, processing time and H₂O₂ dosage how to influence COD of wastewater, ammonia and color and orthogonal. Meanwhile, the experiment conditions were optimized by orthogonal test. The results show that ultrasonic synergy H₂O₂ treatment sewage from piggery is a feasible method. The optimal process conditions for the treatment of the sewage by ultrasonic synergism are as follows: current of 0.7 A, processing time of 2 min and H₂O₂ dosage of 3%. Under such conditions, the COD removal rate can reach up to 95%,the content of ammonia is reduced to 14~15 mg/L, ammonia smell is remarkably improved, and the raw sewage change from black to light yellow.
