Patent ID: 8569045

Claim:
A water toxicity detecting apparatus using sulfur particles comprising: a single reaction container containing unrestrained injected microbes accreted on surfaces of externally-supplied sulfur particles, in which the externally-supplied sulfur particles and oxygen are reacted to form sulfate ions by the microbes; a water sample inlet through which an inflow water sample is flown into the single reaction container; an air inlet through which an air is flown into the single reaction container; a first detection unit which is configured to detect only pH and electrical conductivity of the inflow water sample flown through the water sample inlet; a second detection unit which is configured to detect only pH and electrical conductivity of a water sample containing the sulfate ions generated in the single reaction container; a central processing unit which stores data of the ph and electrical conductivity of the inflow water sample flown through the water sample inlet, adjusts a pumping speed of a pump provided to the water sample inlet and a flow rate of the air, and compares data of the first detection unit with data of the second detection unit to determine presence of toxicity of the water sample via only differences in pH and electrical conductivity resulting from differences in sulfate ion concentration from the first detection unit and the second detection unit; and an outlet through which an after-toxicity-test water sample is exhausted from the single reaction container.
