| 摘 要： | 合成洗涤剂是现代化学工业发展的重要产物之一,它广泛应用于家庭和工业部门,近年来我国合成洗涤剂工业迅猛发展,1986年总产量已达115万吨,居世界第二位。我国目前生产的洗涤剂中LAS占有较大比重。从世界发展趋势看,在今后相当的一段时期内,LAS仍是使用和发展的重点。因此,必须对LAS给水环境带来的污染及其潜在危害要有高度的重视,并采取相应的有效措施,以控制

| Abstract: | The results of this work indicate that the removal of LAS (linear alkyl benzene sulfonate) in the municipal sewage plant is due to absorption of activated sludge and biodegradation. LAS in the wastewater will not have great effect on respiration of activated sludge and TOC as well as total nitrogen removal when its below 20 to 40 mg/L. The toxicity of wastewater containing LAS toward Dephnia magna will decrease greatly after the biological treatment. The 96h-LC50 of LAS to D. magna is 6.2mg/L. Thus,when LAS concentration in fishery water is below 1.0mg/L,it may be considered safety. |
