Abstract

The invention discloses an aquatic organism toxicity experiment device for researching organic pollutants in shallow groundwater. The aquatic organism toxicity experiment device comprises an experiment rack, an experiment sample storage box, a diluent storage box, a culture solution storage cylinder, an experiment box, a concentration detector and a controller, the experiment sample storage box and the diluent storage box are arranged at the upper end in the experiment rack, the culture solution storage cylinder is arranged in the experiment rack and located at the lower end of the experiment sample storage box, the culture solution storage cylinder is communicated with the experiment sample storage box and the diluent storage box through guide pipes, and the experiment box is arranged at the lower end in the experiment rack and is communicated with the culture solution storage cylinder through a guide pipe. The concentration detector is arranged on the side wall of the experiment rack, and a detection probe of the concentration detector is arranged in the culture solution storage cylinder; the controller is electrically connected with the concentration detector; the device is reasonable in structural design, convenient to operate, high in reliability and suitable for large-scale popularization.

Description

technical field [0001] The invention relates to the technical field of aquatic organism toxicity research, in particular to an aquatic organism toxicity experimental device for studying organic pollutants in shallow groundwater. Background technique [0002] With the rapid development of my country's economy, environmental problems have become increasingly prominent, and the scope, degree and number of relocated or abandoned organic pollution sites are showing an upward trend. If these legacy sites are not managed and restored effectively, there will be great potential harm to soil, surface water, ground water and the surrounding environment. At present, site pollution investigations are usually based on chemical tests, which are difficult to intuitively and comprehensively reflect the comprehensive impact of various toxic and harmful substances on the surrounding environment or organisms. Therefore, it is necessary to carry out biotoxicity diagnosis research on the pollute...
