电解协同微纳米泡耦合过一硫酸盐处理农村生活污水的研究
Study on Treatment of Rural Domestic Wastewater by Using Electrolysis and Peracetic Acid Coupled with Micro-nano Bubble
摘要
Abstract
In response to the problems of large land occupation,high treatment cost and susceptibility to external influences in rural domestic wastewater treatment,the treatment effect of electrolysis and peracetic acid coupled with micro-nano bubbles was explored in this study.By examining the effects of iron-carbon ratio,reaction time,PMS dosage,MBs air intake,current intensity,and initial pH on treatment efficiency,the optimal treatment conditions were determined.The results showed that when the reaction time was 120 minutes,the PMS dosage was 0.15 mmol/L,the pH was 7,the MBs air intake was 20 mL/min,the current intensity was 10 A,and the iron-carbon mass ratio was 1∶1,the pollutant removal effect was the best,with a COD removalrate of 86.98%,ammonia nitrogen removal rate of 77.18%,total nitrogen removal rate of 53.61%,and total phosphorus removal rate of 75.67%.The free radical quenching experiment showed that sulfate,hydroxyl and superoxide free radicals were the main active substances for degradation.This study provides a non-biochemical synchronous carbon and nitrogen removal and phosphorus removal technology without adjusting the pH of wastewater,providing guidance for the application of electrolysis and peracetic acid coupled with micro-nano bubble in rural domestic wastewater treatment.关键词
