Description

TECHNICAL FIELD

[0001] The utility model belongs to water treatment device field, especially is involved in a kind of ultraviolet turbidity removal device for water treatment. BACKGROUND

[0002] Water treatment refers to the process of purifying, treating and improving raw water (such as surface water, groundwater, seawater, sewage, etc.) by physical, chemical, biological and other methods to meet the water quality requirements of specific purposes (such as drinking water, industrial water, agricultural irrigation, landscape water, etc.). The purpose of water treatment is to remove impurities, pollutants and harmful substances in water, and to adjust the physical and chemical properties of water to achieve the desired water quality standards. Among them, ultraviolet and turbidity removal are the most commonly used, efficient and environmentally friendly treatment methods in the process of making raw water meet drinking water standards. Ultraviolet light can penetrate the cell wall and cell membrane of microorganisms, damage the structure of DNA or RNA, and thus prevent the reproduction and survival of microorganisms. This method can effectively kill bacteria, viruses, fungi and protozoa in water, reduce microbial contamination in drinking water, and ensure the health and safety of drinking water. Turbidity removal can effectively remove suspended solids and impurities in water, which are the main causes of water turbidity, including silt, algae, organic particles, etc.

[0003] Currently, ultraviolet light achieves sterilization by destroying microbial DNA, but it is sensitive to water turbidity. High turbidity water is blocked by suspended particles, which reduces the sterilization efficiency of ultraviolet light. Therefore, a split technology combination is commonly used in water treatment to achieve turbidity removal and sterilization function, i.e. reducing turbidity by pre-filtering before ultraviolet disinfection, otherwise the penetration rate of ultraviolet light is insufficient and the sterilization effect is unstable. However, such split design not only leads to a large overall volume of the device, but also increases installation and maintenance costs. In addition, the traditional ultraviolet lamp is fixed on the inner wall of the pipeline, and the irradiation intensity in the center area of the water flow is insufficient, which easily forms a sterilization blind area.
