A water quality ammonia nitrogen online monitor

Abstract

The invention belongs to the field of water quality detection, and is specifically a water quality ammonia nitrogen online monitor; it includes a driving wheel, a rotating shaft, a water delivery plate, a connecting rod, a water inlet pipe and a box body, and the rotation of the driving wheel is driven by a motor. The rotation drives the movement of the rotating shaft and the water transfer plate, so that the water transfer plate can well filter the filtered water in the tank, and the water inlet pipe will filter the water flow delivered by the water transfer plate again, and the filtered water will flow into the tank; The cleaning film installed in the box will clean the impurities on the surface of the probe to reduce the impurity content on the surface of the probe. At the same time, the detection barrel installed in the box will clean the impurities on the surface of the probe when the probe is inserted into the water, thus improving the performance of the present invention. The effect of cleaning impurities on the surface of the probe.

Description

technical field [0001] The invention belongs to the field of water quality detection, in particular to an online water quality ammonia nitrogen monitor. Background technique [0002] Water is an important medium for the circulation of various elements in the natural environment. The pollutants produced by human production and life are usually discharged into the natural environment in the form of aqueous solution, which changes the chemical composition and water quality of the water body in the natural environment, thus affecting the water used for industrial and agricultural production and water quality. Water for human life; at the current stage, the pollution of surface water in China is still quite severe. Ammonia nitrogen exists widely in surface water and groundwater. Ammonia nitrogen (NH3-N) exists in water bodies in the form of free ammonia (NH3) or ammonium salt (NH4+) ; Ammonia nitrogen is an important factor of eutrophication in water bodies.

[0002] Water is an important medium for the circulation of various elements in the natural environment. The pollutants produced by human production and life are usually discharged into the natural environment in the form of aqueous solution, which changes the chemical composition and water quality of the water body in the natural environment, thus affecting the water used for industrial and agricultural production and water quality. Water for human life; at the current stage, the pollution of surface water in China is still quite severe. Ammonia nitrogen exists widely in surface water and groundwater. Ammonia nitrogen (NH3-N) exists in water bodies in the form of free ammonia (NH3) or ammonium salt (NH4+) ; Ammonia nitrogen is an important factor of eutrophication in water bodies. When the ammonia nitrogen content in water is high, the water body will be black with odor, which will cause poisoning to aquatic plants and even lead to the death of fish and shrimp aquatic organisms; Under the action, it can be decomposed into nitrite. When the nitrite content in the water exceeds the standard, drinking this water will make the nitrite combine with the protein in the human body to form a strong carcinogen - nitrosamine. If the amount of ammonia nitrogen exceeds the standard for a long time Water is also extremely unfavorable to the body; therefore, the ammonia nitrogen content is an important indicator for evaluating the quality of the water environment; the currently used ammonia nitrogen monitor directly contacts the probe with the sample water sample, and the impurities in the sample water sample will Adhesion to the surface of the probe causes errors when the probe detects the ammonia nitrogen content of the water quality
