Description

The present invention relates to a variety of water quality measurement automation systems capable of simultaneously executing sensor-type water quality measurement and chemical reaction method water quality measurement and analysis, and to an automated method thereof, and in particular, water quality management of large chemical plants, farms, fish farms, aquariums, etc. In the device, it is possible to measure and analyze pH, DO (dissolved oxygen), water temperature, alkalinity, nitrite (NO ₂ ), nitrate (NO ₃ ), ammonia (NH ₄ 4) at the same time. About.

In general, a multi-species (multi-item) water quality measurement device is a process that measures various measurement items with one measuring instrument and transmits the data in the process of wastewater, water supply, drainage basin, power plant, and general production line. Means that.

For example, the water quality measurement device is used in the field of water quality control, water quality measurement monitoring and control, measuring temperature of water quality, measuring hydrogen ion, measuring chemical oxygen demand, measuring suspended matter, measuring total nitrogen, measuring total salvage, measuring chlorine, etc. Is to do. Such, conventional water quality measurement apparatus is configured to measure water quality using a water quality measurement apparatus configured individually for each measurement item.

However, in order to measure the characteristics of various components and various items of water quality, a water quality measuring device suitable for each item is individually measured, which is complicated for measurement and the cost of purchasing and operating multiple water quality measuring devices is high. There was a problem.

On the other hand, dissolved oxygen (DO) refers to the amount of oxygen dissolved in water and is supplied by oxygen in the air, and the amount of dissolved oxygen depends on the temperature or atmospheric pressure, and the DO of pure water at 20°C under atmospheric pressure is about 9 ppm, and the temperature is As it decreases, it rises and becomes about 13 ppm at 4°C. The concentration of dissolved oxygen varies depending on the temperature, atmospheric pressure and concentration of impurities, and most of the water in nature can maintain a calm state, but depending on environmental conditions, the water surface is not calm and turbulent due to the influence of wind. In the event of turbulence, oxygen in the atmosphere melts into the water. In this way, the dissolution of oxygen in the atmosphere into the water is called transfer, and the rate at which it dissolves is called the transfer rate.

And the minimum survival concentration of dissolved oxygen for fish and shellfish aquatic is 5ppm or more, and when DO is less than 2ppm, odor starts to occur. The relationship between dissolved oxygen and self-purification in river water is a question of whether oxygen balance is maintained in that it is a balance of the amount of oxygen generated by reaeration and deoxygenation (oxygen consumption) against the progress of self-purification.

The above-described measurement of dissolved oxygen is performed to maintain conditions favorable for the growth and reproduction of fish stocks and other aquatic organisms, that is, to ensure that dissolved oxygen is present in a sufficient concentration to keep aquatic organisms in a healthy state at all times.
