Description

Technical Field

[0001] The utility model mainly relates to the technical field of quality-based water supply, in particular to a quality-based water supply device for industry. Background Art

[0002] With the advancement of domestic urbanization and the integration of urban and rural water supply, the difficulty of water source construction and the pressure of ecological environment protection of water sources will increase, and the contradiction between supply and demand of high-quality water resources will be further aggravated. The implementation of differentiated water supply for life and industry is to adapt to the needs of diversified water uses and water demands, to meet the needs of rational allocation of water resources, and is also an inevitable trend for the long-term development of urban water supply. Up to now, dozens of cities in my country have implemented differentiated water supply and achieved good economic and social benefits. The so-called "differentiated water supply" is to separate the water supply of large industrial enterprises from the urban tap water supply. The urban tap water supply uses high-quality water sources from reservoirs, and industrial water plants use plain river water as their water source. Industrial water supply implements special pipes and special supply to ensure the "water resource elements" of industrial development, effectively improving the level of urban water use security, actively seeking new water resources, and further optimizing water resource utilization.

[0003] Domestic high-tech industries are constantly updating and upgrading. The more advanced the process, the greater the water consumption and the higher the requirements for the quality of production water. The reverse osmosis system is a very effective membrane separation unit operation, which uses the characteristics of the reverse osmosis membrane to remove most of the soluble salts, colloids, organic matter and microorganisms in the water. The mechanism of the main desalination part of the reverse osmosis membrane element is similar to that of a semipermeable membrane, which can selectively permeate ions in the water. At this stage, the treatment process of the water plant cannot meet the special water needs of high-tech industries. If reverse osmosis membrane elements are used directly, the reverse osmosis inlet water does not meet the standards, which increases the environmental pollution of the reverse osmosis and shortens the service life of the reverse osmosis.

[0004] Based on this, we need to develop a differentiated water supply device for industrial use, which can be installed near industrial areas to provide high-quality water resources to meet the needs of high-tech industries. Utility Model Content

[0027] The specific operation is as follows: the water from the water plant is used as the water source through the tap water pipe 1, and the multi-media filter device 3 is installed in the micro-building module 15 in sequence, and a three-layer filter bed (anthracite layer 31, quartz sand layer 32, gravel layer 33) is used for filtration. The activated carbon filter device 4 uses granular activated carbon, and cooperates with the ultrafiltration system module 5 to form a reverse osmosis system module 6 pretreatment process to reduce the processing pressure of the reverse osmosis membrane. The concentrated water generated by the ultrafiltration system module 5 and the reverse osmosis system module 6 is discharged through the concentrated water discharge pipe 11, and then the tap water comes to the online water quality analyzer 7 for water quality analysis, and then the relevant data is uploaded to the PLC control system module 14. When the water quality does not meet the standard, the PLC control system module 14 closes the second electric valve 8 and opens the third electric valve 12 to discharge the unqualified water in the pipeline through the drain pipe 13 until the online water quality analyzer 7 monitors that the water quality meets the standard, closes the third electric valve 12, opens the second electric valve 8, and continues to supply industrial water.
