摘要
利用泥鳅作为指示生物,以曝气3 d的自来水为对照,研究泥鳅在11.1%浓度的原污水和改性炭K处理过的原污水中,分别染毒处理12、36、60、84 h后泥鳅肝脏SOD、GOT酶活力的变化。结果表明：浓度为11.1%的原污水对泥鳅染毒处理12~36 h后SOD和GOT酶活力呈现上升趋势,随着染毒处理时间的增加,泥鳅体内的SOD和GOT酶活力的逐渐降低;而改性炭K处理过的原污水和对照组对泥鳅处理的各个时段相比较,酶活力变化情况基本相同。11.1%浓度的原污水处理对泥鳅的SOD和GOT酶活性影响与对照相比,t检验结果为差异显著（P〈0.05）和极显著（P〈0.01）。研究表明养猪场污水对泥鳅具有毒性作用,因而影响到其生理生化指标的变化,而改性炭K对污水则有较好的净化作用。
In this experiment,loach（Misgurnus Anguillicaudatus） was used as the biological indicator to evaluate the capacity of carbon K in purifying wastewater from a pig farm.Using tap water,which had been exposed in open air for 3 days,as the control,loaches were fed in water containing 11.1% pig farm wastewater with or without carbon K.The SOD and GOT activity in the liver of the loaches were determined after 12h,36h,60h and 84h.The results showed that after 12 to 36h in the contaminated water,there was an upward trend on the activities of SOD and GOT in the loaches.The activities gradually decreased with contact time.In contrast,the loaches that were raised in either the tap water or contaminated water with carbon K had a similar change in those enzymatic activities during the same time period.The t-test indicated a significant difference on SOD and a highly significant difference on GOT activities between the two groups and the contaminated water group.It was concluded that the pig farm wastewater was toxic to loach affecting its physiology and biochemistry,and that carbon K could be an effective agent used to purify the wastewater from a pig farm effluent.
