Abstract
[Objective] The study aimed to explore the feasibility of the sodium formate in promoting the anaerobic biological degradation of the sucrose wastewater.[Method] The inoculated sludge was from the concentrated pool in a sewage plant in Shanghai City,which was sealed a week after use and the experiment waste water was used by the self-made sucrose wastewater.The experiment was divided into two stages: sludge domesticated stage and load improving stage.The sludge samples in each system were made for microbial diversity analysis by PCR-DGGE technology.[Result] The addition of sodium formate could accelerate the startup of the anaerobic biological system,increase the COD removal rate and the volume loading rate(VLR) of the system,and the effect was more significant as the sodium formate concn.was increased.The addition of sodium formate could improve the settleability of sludge,enhance the microbial concn.,increase its microbial activity,thus increase the COD removal rate.The addition of sodium formate also could change the microorganism species and increase the biodiversity,which also could increase the COD removal rate.[Conclusion] The sodium formate got good effect in promoting the anaerobic biological degradation of the sucrose wastewater.
Sodium formate effectively promotes anaerobic biological degradation of sucrose wastewater, increasing COD removal rate and volume loading rate, with more significant effects as sodium formate concentration increases.
