- Abstract:
- According to the characteristics of fecal filtrate such as high organic matter concentration, good biodegradability and so on, a fecal harmless treatment plant in Hangzhou adopted the combined process of coagulation, two-stage A/O and MBR to treat the fecal filtrate with the treatment capacity of 100 m3/d. The operation results show that the combined process had strong shock loading resistibility and high treatment efficiency. The removal rates of COD, NH3-N, TN, TP and SS were above 94%, 90%, 90%, 91% and 92% respectively. The effluent quality stably met the second level stipulated in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002) and the level C limit stipulated in Wastewater Quality Standards for Discharge to Municipal Sewers (GB/T 31962-2015).
