Secondary water supply deep purification system with coupled quality separation function

Abstract

The invention discloses a secondary water supply deep purification system with a coupled quality separation function. The secondary water supply deep purification system comprises a water tank arranged underground, the system is characterized by further comprising an emergency water quality guarantee unit, a water quality improvement unit, a user water supply pipeline, a return water pipeline anda direct drinking water pipeline, a water inlet of the emergency water quality guarantee unit is connected with a municipal water pipeline; a water outlet of the emergency water quality guarantee unitis connected with the front end of the water tank; the rear end of the water tank is connected with a user water supply pipeline; one side of the water tank is connected with a water inlet of the water quality improvement unit; a concentrated water outlet of the water quality improvement unit is connected with a water inlet end of the return water pipeline; a water outlet end of the return waterpipeline extends into the water tank; a pure water outlet of the water quality improvement unit is connected with a water inlet end of the direct drinking water pipeline; and a water outlet end of thedirect drinking water pipeline is connected with an external direct drinking nozzle. The secondary water supply deep purification system has the advantages that the secondary water supply deep purification system can be combined with a secondary water supply system of a municipal official website, secondary pollutants are removed, and at the same time, the community quality-divided water supply is realized, and the requirements of users on common water, high-quality direct drinking water and the like are met.

Description

technical field [0001] The invention relates to the field of secondary water supply, in particular to a secondary water supply deep purification system coupled with a quality separation function. Background technique [0002] The safety of drinking water is closely related to the life and health of the people and the sustainable development of the economy and society. It is an important symbol of the development level of modern cities and the quality of life of urban and rural residents. Now the tap water treated by the water plant can generally meet the national drinking water sanitation standard, but the huge underground pipe network system is like a large "reactor". Many water quality problems are mainly caused by the water plant and every household. on the "middle link" between the faucets. On the one hand, problems such as aging and corrosion of pipe materials, leakage of water pipe joints, and peeling off of the inner wall of metal pipes are the main sources of "secon...

Problems solved by technology

On the other hand, water supply equipment such as water pumps and water tanks are prone to pollution problems due to poor management or untimely maintenance during secondary water supply, which affects the safety of domestic water.

[0003] The pollution problem of the secondary water supply system is universal, frequent and uncertain

However, it is common to install deep purification treatment equipment for each household, and it is rare to combine the deep purification of high-quality direct drinking water with the secondary water supply system. Therefore, the existing water supply system is likely to cause waste of water resources and equipment. Management and maintenance costs are high, and unified management cannot be performed
