毒性废水稀释中强度改变与浓度改变的跟随性研究

Diluted Wastewater Toxicity Study Followed Changes in Intensity and Concentration

适用于已知毒物和毒性应用剂量测定的经典技术方法,以样品稀释过程中毒性强度改变与浓度改变的等比率跟随性为基础。废水中的毒性物质常以未知和混合为特征,高毒性的样品现状浓度距离方法预试验中最小全致死浓度较远,以已知毒物重铬酸钾毒性为对照,形成5种毒物高层级等强度毒性,通过这些高毒性废水同步等比率稀释后毒性改变的同步性测定试验,证明毒性废水稀释中强度改变与浓度改变的跟随状态具有不确定性。

Classical techniques known methods applicable to toxic poisons and by dose measurement,the samples were diluted to process the intensity change to the concentration of toxic and other changes based on the ratio of followability.Toxic substances in wastewater is often unknown and is characterized by mixed high toxic concentrations of the status quo pre-sample distance method experiments far the smallest full-lethal concentration, potassium dichromate toxic poisons known to control the formation of five kinds of poisons high level,etc. strength toxicity,through these highly toxic wastewater synchronization dilution ratio after synchronization Test Toxicity change proved toxic wastewater dilution and concentration intensity change follows the change in status is uncertain.
