Water disposal facility and method

Abstract

The invention discloses a water disposal facility and method. The water disposal facility comprises a membrane desalination unit, a first channel, a second channel, an electric separation unit, a third channel, a fourth channel, a sediment unit, a fifth channel, a sixth channel, a seventh channel, and an additive unit, wherein the first channel is used for inputting a first input flow into the membrane desalination unit; the second channel is used for outputting a first product flow with the salt content lower than that of the first input flow from the membrane desalination unit; the third channel is used for outputting a first discharge flow with the salt content higher than that of the first input flow from the membrane desalination unit into the electric separation unit; the fourth channel is used for outputting a second product flow with the salt content lower than that of the first discharge flow from the electric separation unit; the fifth channel is used for outputting a second discharge flow with the salt content higher than that of the first discharge flow from the electric separation unit into the sediment unit; the sixth channel is used for outputting a second input flow with the salt content lower than that of the second discharge flow from the sediment unit into the electric separation unit; the seventh channel is connected with the sediment unit and is used for discharging the discharge flows; and the additive unit is communicated with at least one of the electric separation unit and the sediment unit.

Description

technical field [0001] The invention relates to a liquid treatment device and method, in particular to a water treatment device and method. Background technique [0002] Membrane desalination devices, such as nanofiltration membrane devices or reverse osmosis membrane devices, are used in beverage factories to treat raw water for beverage production due to the reliability of product water quality. However, the membranes of membrane desalination devices have a problem of fouling tendency, so the recovery rate of treated water in conventional membrane desalination devices is about 50% to 90%. The remaining 10% to 50% of the feed water is usually discharged as wastewater. Beverage factories in the world consume a large amount of usable water every day, so it is not advisable to treat a large amount of raw water through a membrane desalination device and discharge a large amount of wastewater, which will result in high cost and high waste. [0003] With the exception of bevera...
