Lake water pH value detection device for removing algae influence

Abstract

The invention belongs to the technical field of water quality detection, and discloses a lake water pH value detection device for removing algae influence, the lake water pH value detection device comprises a water sample collection bottle, the water sample collection bottle comprises a bottle body and a bottle cap; the bottle body comprises a shell and an inner container, and a vacuum interlayeris arranged between the shell and the inner container; a refrigerator is arranged at the bottom of the bottle body, a pH sensor is arranged in the inner container, and the pH sensor is electrically connected with data processing equipment; a miniature water taking pump is arranged on the bottle cap, a water inlet of the miniature water taking pump is connected with a water taking pipe, a water outlet penetrates through the bottle cap to be communicated with the inner container, and a filtering assembly is arranged on the inner side of the bottle cap. When the lake water pH value detection device is used for detection, the bottle cap is tightly connected with the bottle body, a water sample is collected by the miniature water taking pump and filtered by the filtering assembly so that the water sample entering the inner container does not contain algae, and meanwhile, the refrigerator is used for refrigeration, and thus the water sample is in a low-temperature and dark environment, and the influence of algae on the water sample is effectively eliminated; and the accuracy of water quality pH value detection is improved.

Description

technical field [0001] The invention belongs to the technical field of water quality detection, and in particular relates to a lake water pH value detection device for removing the influence of algae. Background technique [0002] PH value is an important indicator of lake water quality. Although it cannot independently reflect the quality of lake water, it can reflect the ecological environment of lake water in combination with other water quality indicators. In the prior art, the pH sensor is generally used to directly put the pH sensor into the lake water to be tested for pH value detection. However, due to the influence of nitrogen and phosphorus organic matter in some lake water, the water body becomes eutrophic, and algae are easy to grow, especially in summer when the daytime temperature is high. Under the condition of strong light, algae carry out photosynthesis, and the hydrogen in the water reduces carbon dioxide to synthesize organic substances, and the algae incr...

Problems solved by technology

In the prior art, the pH sensor is generally used to directly put the pH sensor into the lake water to be tested for pH value detection. However, due to the influence of nitrogen and phosphorus organic matter in some lakes, the water body is eutrophic, and algae are easy to grow, especially in summer when the daytime temperature is high. In the case of strong light, algae carry out photosynthesis, hydrogen in the water reduces carbon dioxide to synthesize organic substances, and the algae increase in large quantities. Affected by algae, the pH value of the lake water is high at this time, which cannot truly reflect the pH value of the lake water, resulting in unreliable detection data.
