Abstract

The invention discloses a water treatment system which comprises a system inlet, a water storage container I, a system outlet and an ultraviolet sterilizer. Water treated by the system sequentially flows through a first activated carbon filter, a second activated carbon filter, a particulate filter and membrane equipment and is stored in the water storage container I. The ultraviolet sterilizer is positioned at the downstream of the system outlet. The water treatment system further comprises an ozone subsystem, a recirculation subsystem and a main programmable logic controller. The ozone subsystem comprises an ozone generator for generating ozone and at least one connection point along the flow path for introducing ozone into process water. The recirculation subsystem operates regularly to extract the treated water from the water storage container I to form circulating water, and introduces the circulating water into a water conveying pipeline at the upstream of the ultraviolet sterilizer. The main programmable logic controller is used for controlling the flow of process water flowing through the water treatment system, the yield of ozone and the ultraviolet radiation intensity, and controlling the circulation subsystem.

Description

technical field

[0001] The invention relates to water treatment, in particular to a water treatment system. Background technique

[0002] Drinking water from municipal water supplies usually undergoes some form of treatment to sanitize the water as it is obtained from the final source. Depending on the efficiency of the disinfection system and whether additional water treatment is performed at the municipal level, potable water from municipal supplies may still have an unacceptable taste and odor and may contain potentially unhealthy disinfection by-products (DBP). For example, chlorine is a typical disinfectant used by municipalities, and by-products of water chlorination include trihalomethanes (THMs) and other chlorinated compounds, which have been linked to carcinogenicity and other diseases in humans.

[0003] To alleviate the aforementioned potential problems with municipal water, buildings are equipped with point-of-entry water treatment systems to further treat muni...
