Centrifugal water quality comprehensive toxicity detection chip

Abstract

The invention discloses a centrifugal water quality comprehensive toxicity detection chip. The chip comprises a cover plate layer and a channel layer, wherein the cover plate layer is arranged on thetop of the channel layer and is in sealing fit with the channel layer; the cover plate layer is a transparent plate and is provided with a resuscitation liquid feeding hole, a contrast liquid feedinghole, a liquid-to-be-detected feeding hole, a vent hole and a cover plate layer chip fixing hole; the channel layer is provided with a luminescent bacteria storage area, a liquid separation area, a contrast liquid detection area, a liquid-to-be-detected detection area, a waste liquid area and a channel layer chip fixing hole; and a luminescent bacteria freeze-dried powder is stored in the luminescent bacteria storage area, and the luminescent bacteria storage area communicates with the resuscitation liquid feeding hole through a resuscitation liquid feeding channel. The chip is simple and convenient to operate, and a user can obtain a detection result by a detector after adding a liquid, and does not need to wait beside the chip; and during detection, slight shaking and standing are carried out alternately, so that a bacteria liquid is uniformly mixed and does not have sedimentation effect which can cause thalli to gradually show different bacterial density distributions in the longitudinal direction, and the detection result is ensured to be more accurate.

Description

technical field [0001] The invention relates to the technical field of environmental detection, in particular to a centrifugal water quality comprehensive toxicity detection chip. Background technique [0002] With the development of industrialization, the safety situation of water sources and drinking water is becoming more and more serious, which seriously threatens the health of residents. Although the traditional water quality safety detection method has high precision and sensitivity, the detection steps are complicated, time-consuming and labor-intensive. Moreover, the toxins in the water body are various and complex, and it is difficult to detect multiple toxins at the same time. The luminescent bacteria inhibition method uses a sensitive photoelectric measurement system to measure the influence of poisons on the luminous intensity of luminescent bacteria, so as to evaluate the presence and intensity of poisons in water. In addition, due to the similarity between ba...
