Description

A kind of water quality detection device and control method thereof

technical field

The invention belongs to the technical field of household appliances, and in particular relates to a water quality detection device and a control method thereof.

Background technique

Because tap water itself contains harmful components such as rust, impurities, chlorine, pathogenic microorganisms, and the water quality of tap water varies greatly between regions. Health and safety issues caused by unclean bath water have long been a pain point for some users. Especially for some special user groups, with the improvement of living standards, their requirements for bathing water quality also tend to be higher.

As tap water is affected by chemical composition and environmental pollution, bathing does tend to get dirtier. Bathing is the most important way for the human body to directly contact the water source, and the harmful substances in the water will directly harm the skin and hair. For example, residual chlorine and scale are destructive. Residual chlorine destroys the protein of the skin and causes skin aging; limescale forms calcium and magnesium soap on the skin surface, preventing skin absorption, and it is futile to use more cosmetics.

For example, when using hard water to wash your face, calcium and magnesium salts interact with soap to form water-insoluble calcium-magnesium soap, which is like a colloidal and sticky substance, which is not easy to remove when it adheres to the skin. In this way, the dirt on the original skin has not been washed, and new dirt has been added. The viscous substances formed by these dirt and calcium and magnesium soap block the openings of the skin glands, which not only block the skin's excretion channel, form embolism, stimulate the skin, but also affect the normal metabolism of the skin, causing the skin to shrink and age prematurely. Therefore, we should pay attention to choosing soft water with low hardness when taking a bath.

Furthermore, residual chlorine is often used in tap water and swimming pool water. A certain amount of residual chlorine can ensure that the water quality does not breed bacteria, etc. However, after the residual chlorine exceeds the standard, it will easily irritate the eyes, nose, throat and upper respiratory tract, causing acute pulmonary edema. When the concentration is high, the respiratory center can be paralyzed and "flash death" occurs. Long-term inhalation of low-concentration chlorine can cause chronic poisoning and lead to the speed of aging in the body. The main diseases are rhinitis, chronic bronchitis, emphysema, liver cirrhosis, atherosclerosis, and even cancer. Chlorine when added to water can cause dry, breakage, split ends, bleaching of your skin, peeling of layers, and an itchy allergy to psoriasis. Chlorine produces carcinogens such as chloroform when heated with organic humus in water.

Organic substances in water mainly refer to polycarboxylic acid compounds of humic acid and fulvic acid, pollutants of domestic sewage and industrial wastewater. Among them, the weak organic acid of the former multifunctional aromatic macromolecules accounts for more than 95% of the organic substances dissolved in water. Humic substances are the products of life activities such as aquatic organisms. Domestic sewage is mainly human excrement and garbage waste. The organic substances in various industrial wastewaters include animal and plant fibers, oils, sugars, dyes, organic acids, various organically synthesized industrial products, and organic raw materials. These organics contaminate water bodies and deteriorate water quality.

The organic substances in the water body have a common feature, that is, to carry out biological oxidation and decomposition, the dissolved oxygen in the water needs to be consumed, which leads to the lack of oxygen in the water. At the same time, corruption and fermentation will occur, causing bacteria to grow, deteriorating water quality, and destroying water bodies.

The present invention has been made in view of this.
