葡萄糖为共基质下多溴二苯醚产甲烷毒性的研究
DOI: 10.3969/j.jssn.1000-2006.2009.02.027
Keywords: 多溴二苯醚,产甲烷毒性,共基质,葡萄糖
Abstract:
在中温厌氧条件下，以葡萄糖为共基质，采用间歇试验法，通过测定甲烷累积产量，研究了十溴二苯醚和4,4’二溴二苯醚的厌氧生物降解性，利用相对活性值判断多溴二苯醚对产甲烷菌的抑制程度。结果表明：在受试浓度下，测定条件为35℃、化学需氧量(cod)10000~11000mg/l、ph7.0~7.5时，十溴二苯醚对产甲烷菌产生轻度抑制；二溴二苯醚在质量浓度为5mg/l条件下对产甲烷菌产生中度抑制，其余浓度条件下对产甲烷菌产生轻度抑制。
