摘要:In order to solve the problem of removal of carbon and nitrogen of rural sewage , the paper used an anaerobic hydrolysis -SNAD process to treat this kind of wastewater with low C/N ratio.The results show that , when the C/N ratio of influent in hydrolysis acidification unit is 2 to 1 , the removal efficiency of COD reaches 69%.The main components of VFAs are acetic acid , propionic acid and ethacetic acid . The average contents are 88.4%, 6.5%and 5.1%respectively.Meanwhile the ratio of VFAs and COD reaches 0.74 and the ratio of C/N in effluent is 3 to 5.The hydrolysis acidification unit come into SNAD nitrogen removal unit , through the action of the coupling of partial nitrification , denitrification and anam-mox, the removal efficiencies of COD and total nitrogen reach 76.7%and 84.1%respectively.The re-moval ratio of COD and total nitrogen by using anaerobic hydrolysis -SNAD combined process reach 92 . 8%and 84 .1%respectively .
