采用厌氧毒性试验研究了四甲基氢氧化铵（TMAH）在升流式厌氧污泥床（UASB）中的毒性。通过监测总有机碳（TOC）和离子色谱（IC）分析来确定系统性能。结果表明，TMAH浓度小于10 000 mg/L时对厌氧古菌无毒性。废水中的TMAH在厌氧条件下完全降解，并转化为沼气（CH 4和CO2）和NH3。在240天的实验中，UASB的最大容积负荷分别为6.95 kg TMAH/m3-day（4.0 kg TOC/m3-day）和7.30 kg TMAH/m3-day（4.1 kg TOC/m3-day）。UASB处理含THAM废水的去除率均大于95%。
Toxicity of tetra-methyl ammonium hydroxide (TMAH) was investigated in an upflow anaerobic sludge bed (UASB) by anaerobic toxicity assay test. System performance was determined by monitoring total organic carbon (TOC) and ion chromatograph (IC) analysis. The result indicates that TMAH concentration less than 10 000 mg/L is nontoxic to the anaerobic archaea. TMAH containing in the wastewater was completely degraded under anaerobic condition and was transferred to biogas (CH4 and CO2) and NH3. The maximum volumetric loading of UASB is 6.95 kg TMAH/m(3) -day (4.0 kg TOC/m(3) -day) and 7.30 kg TMAH/m(3) -day (4.1 kg TOC/m(3) -day) for synthetic wastewater and wastewater from a full-scale thin-film transistor liquid crystal display manufacturing industry during the 240-day experiment, respectively. The removal efficiencies of THAM containing wastewater were both higher than 95% treated by UASB.
