摘　　要：针对肝素废水的厌氧处理,研究盐度(以NaCl计)为33 OOO mg·L^(-1)时不同进水有机负荷下,投加甜菜碱对厌氧系统有机物去除、氨化作用等的影响。实验结果表明:进水有机负荷1.33、1.66、2.0 kg·(m^3·d)^(-1)的条件下,甜菜碱的添加对高盐厌氧系统的性能均有不同程度的促进作用。当甜菜碱为1.5 mmol·L^(-1)时,对COD去除的促进效果最为明显,COD去除率最多提高了37.6%;同时氨化率也有较大的提高最多提高了31%。For anaerobic treatment of heparin wastewater,the effects of adding glycine betaine on the removal of organics and ammonification of the anaerobic system were studied,at a salinity of 33 000 mg·L^-1（caculated by NaCl） and different organic loadings of the influent.The results showed that different dosages of glycine betaine affected the anaerobic system differently with high salt,when the organic loadings of the influent were 1.33,1.66,and 2.0 kg·（m^3·d）^-1.The removal efficiency of COD was highest when glycine betaine was 1.5 mmol· L^-1 and increased by 37.6%,at most.Meanwhile,the ammoniated rate increased by 31%,at most.
