An optical water-quality detection apparatus includes a detection device, a biofilm-inhibition light source, a detection light source and a sensor. The detection device includes a detection chamber. The biofilm-inhibition light source is disposed outside the detection chamber and configured to emit biofilm-inhibition light. The detection light source is disposed outside the detection chamber and configured to emit detection light. The sensor is configured to sense the detection light penetrating the detection chamber. A beam of the detection light and a beam of the inhibition light overlaps as penetrating the detection chamber.

Optical water-quality detection apparatus

A residual toxicant detection device for testing residual toxicant in an aqueous solution is disclosed, which includes a first space cavity, a second space cavity, a connecting frame and a sensing cavity. The first space cavity includes a light source and a lens. The second space cavity includes a photo sensor and a circuit module. The connecting frame is configured to connect the first space cavity and the second space cavity. The sensing cavity for receiving an aqueous solution is formed between the first space cavity and the second space cavity and at one side of the connecting frame. The light source emits a light with a wavelength range. The photo sensor receives the sensing signal of the light passing through the sensing cavity. The circuit module is configured to calculate the absorbance and the variation in absorbance of the residual toxicants in the aqueous solution.
