摘要
模拟太湖水中阿特拉津浓度突增的情况,研究了臭氧氧化、生物活性炭吸附降解及臭氧/生物活性炭联用工艺对其去除效果,并初步分析了各工艺参数的影响。结果表明,单独臭氧氧化对阿特拉津的去除率约为31%,而生物活性炭工艺的去除率则可达到73%;臭氧氧化可强化生物活性炭对阿特拉津的去除效果,两者联用对阿特拉津的去除率高达95%;破碎炭上的生物量明显高于柱状炭,针对水中阿特拉津的去除,破碎炭更为适用;臭氧/生物活性炭工艺的炭层厚度建议采用150 cm,此值可在保证阿特拉津去除效果的同时,保障出水水质安全性。
The removal efficiencies of atrazine by O3 , biological activated carbon （BAC） and O3/ BAC process were investigated by simulating the sudden increase of its concentration in Taihu Lake water, and the technical parameters were analyzed. The results indicate that the removal efficiency of at- razine by ozonation is 31%, while BAC process can remove 73% of atrazine. Ozonation can enhance the removal efficiency in BAC process, and the removal efficiency of atrazine by O3/BAC process can reach 95%. Biomass on crushed carbon is evidently higher than that on columnar carbon. To remove atrazine, crushed carbon should be chosen to fill the activated carbon column. The proper thickness of activated carbon column in O3/BAC process should be 150 cm which can ensure the removal efficiency of atrazine and the safety of treated water.
