- Abstract
[Objectives] The study aimed to discuss the optimal conditions for the treatment of intestinal lavage wastewater by coagulation-ASBRSBR process. [Method] According to the water-quality characteristics of wastewater from a heparin sodium production factory of Jiangsu Province, intestinal lavage wastewater was segregated from enzymolysis wastewater and treated using coagulation-ASBR-SBR process, and the effects of PFS dosage, HRT of ASBR and SBR reactor on the removal rate of COD and NH4+-N were analyzed. [Result] The best dosage of PFS was 0.15 g/L, and the optimal HRT of ASBR reactor was 36 h, while the best HRT of SBR reactor was 15 h. Under the optimal conditions above, the removal rate of COD and NH4+ -N reached 99. 1% and 97.3% respectively, and the quality of the effluent water could reach the first standard of Comprehensive Discharge Standard of Sewage (GB8978-1996). [Conclusion] The research could provide a new process for the treatment of intestinal layage wastewater.
