The invention discloses a water quality field detection worktable which comprises a worktable body. A water sample testing device is arranged on the worktable body and comprises a plurality of water sample testing grooves, valves, water leakage grooves, a conduction pipe and sewer lines, the water sample testing grooves are formed in the upper surface of the worktable body, the water leakage grooves are formed in the bottoms of the water sample testing grooves and connected with the conduction pipe through the sewer lines, a water outlet is formed in the outer wall of the worktable body, the conduction pipe is connected with the water outlet, the valves are arranged at the water leakage grooves, and an operation device for the valves is arranged on the outer wall of the worktable body. Thewater quality field detection worktable has the advantages that the worktable is simple in structure, easy to manufacture, convenient to carry, firm and stable, the working efficiency of the worktable is enhanced by the aid of a circular baffle plate, a researcher more simply and conveniently detect water quality on field, and instruments achieve excellent performances.
