摘要: 采用厌氧接触式反应器，对自配丙烯酸（AA）废水进行预处理。反应器经污泥驯化稳定运行后，在HRT为12 h，进水丙烯酸浓度为1 000~3 000 mg/L，丙烯酸容积负荷为2~6 kg AA/(m3·d)，污泥负荷为0.67~2.00 kg AA/(kg VSS·d)的条件下，丙烯酸去除率达95%以上，出水丙烯酸浓度低于160 mg/L，出水pH在6.8~7.5之间，COD去除率为20%~40%。可将平均每4 mol丙烯酸转化成1 mol乙酸和1.7 mol丙酸，从而实现丙烯酸废水的脱毒，便于后续的产甲烷处理。

Abstract: An anaerobic contact reactor was used for the pretreatment of synthetic wastewater containing high-concentration acrylic acid (AA). After sludge acclimation of the reactor, the removal rate of AA was above 95% with effluent acrylic acid less than 160 mg/L and COD removal rate of 20%~40%, under the following conditions: hydraulic retention time of 12 h, influent concentration of 1 000~3 000 mg AA/L, volumetric load of 2~6 kg AA/(m3·d), sludge load of 0.67~2.00 kg AA/(kg VSS·d). The reactor can transform each 4 mol acrylic acid into 1 mol acetic acid and 1.7 mol propionic acid, and thereby achieve the detoxification of acrylic acid, which can faciliate the following methane production.
