Marine large-flow drinking water tail end purification system

Abstract

The invention discloses a marine large-flow drinking water tail end purification system. The system comprises a raw water pipeline, an activated carbon filter, a precision filter, an ultraviolet sterilizer and a purified water outlet pipeline which are sequentially communicated, the raw water pipeline is communicated with the top of the precision filter through a first backwashing pipeline, and the bottom of the precision filter is communicated with a deslagging and discharging port through a second backwashing pipeline; a fourth electromagnetic valve, a second electromagnetic valve, a first electromagnetic valve and a third electromagnetic valve are sequentially and correspondingly arranged on a first pipeline, a third pipeline, a first backwashing pipeline a the second backwashing pipeline respectively; and each electromagnetic valve and a flow detection device are connected with an electric control box respectively. The system has the beneficial effects that the fresh water from thedrinking water cabin is continuously treated by adopting an 'adsorption+ filtration + disinfection' process, and small molecular substances such as bacteria and microorganisms are effectively filtered, so that the effluent quality meets related standard requirements.

Description

technical field [0001] The invention relates to the design technology of a ship's daily water system, in particular to a ship's large-flow drinking water terminal purification system. Background technique [0002] With the increasing size of ships, how to further improve the living standard of the crew during the long-term voyage of the ship has also attracted more and more attention. [0003] The drinking water carried or prepared by the ship is stored in the drinking water tank, and the drinking water stored in the drinking water tank is disinfected by timely and appropriate chlorine disinfection in the drinking water tank. There may be secondary pollution in the process of sending drinking water from the drinking water tank to large-flow users (such as kitchens, water boilers, etc.) through pipelines; drinking water will have some peculiar smell after a period of storage in the drinking water tank, and The drinking water terminal purification system is used to continuous...

AI Technical Summary

Problems solved by technology

However, there are many people on a large ship, and the kitchen, water boiler, etc. need to use a large amount of drinking water at the same time, and the demand for drinking water increases. The purification capacity of the conventional design is limited, and it cannot meet the needs of daily use.
