The utility model belongs to the technical field of
sewage toxicity exposure and detection, and particularly relates to an adjustable
wastewater in-situ biological
toxicity exposure and detection
zoning device which comprises a detection shell, a partition plate which is detachable from the detection shell is arranged in the detection shell, and the interior of the detection shell is divided into a detection area and a biological chronic
toxicity exposure area through the partition plate. An equipment storage box is arranged above one side of the detection shell, an aerator and a heating rod device are symmetrically placed in the storage box, and the aerator and the heating rod device penetrate through wire holes formed in the storage box through wires respectively to be connected with an external power source; the
aeration machine conveys
oxygen to the bottoms of the concentration detection areas and the biological chronic toxicity exposure areas through hoses, and a heating rod device of the
aeration machine transmits a heat source to the corresponding detection areas or the biological chronic toxicity exposure areas through small holes in the bottom of the storage box; according to the utility model, simultaneous exposure of
acute toxicity and chronic toxicity of
wastewater organisms can be realized, and
acute toxicity data and chronic toxicity biological samples can be obtained.
