利用发光菌和大型蚤对北方某城市再生水急性毒性的调查
Toxicity evaluation of reclaimed wastewater in a city in north China by using luminescent bacterium and Daphnia magna
摘要
Abstract
The acute toxicities of influents of five reclaimed water plants ( effluents from sewage treatment plants) and two reclamation facilities in a city in north China were investigated by using Photobacterium phosphorem T3 and Daphnia magna. The higher TIR48 (total inhibitory rate of 48 hours for Daphnia) of 90％ and 100％, LIR ( luminescence inhibition rate for Photobacterium) of 74. 2％ and 46.5 ％, respectively, were found for the influents of reclaimed Plants K and B receiving high percentage of industrial wastewater. The acute toxicities of effluents were reduced to some degree after reclamation treatment processes in Plants J and K. However,the acute toxicities increased after chlorine disinfection or ozone treatment. Two methods can reflect the toxicity of reclaimed water,white the method of Daphnia is more sensitive.关键词
