| 摘要 | With the continuous deepening of rural revitalization strategy and the increasingly strict sewage discharge standards, rural domestic sewage treatment technology is facing higher challenges and requirements. The combined process of micro-electrolysis + micro-nano bubbles coupled with peroxymonosulfate was constructed in this study, and the treatment effect and application value of this technology were explored with the actual rural domestic sewage as the treatment object. The experimental results showed that under the conditions of HRT of 120 min, PMS dosage of 0.15 mmol/L, pH=7, MBs air intake of 15 mL/min, current intensity of 15 A, and Fe/C mass ratio of 1:1, the removal rates of COD, ammonia nitrogen and total phosphorus can reach 88.55%, 77.18% and 74.67%, respectively. Under the condition that the pH value of sewage was not adjusted, the non-biochemical simultaneous decarbonization, denitrification and phosphorus removal of rural domestic sewage can be achieved by micro-electrolysis and micro-nano bubbles coupled with peroxymonosulfate. The concentrations of effluent COD, ammonia nitrogen and total phosphorus met the requirements of the first level standard of the Discharge Standard of Water Pollutants for Rural Domestic Sewage Treatment Facilities (DB45T2413-2021). And the comprehensive operating cost was about 1.15 yuan/m³. |
