Abstract

The invention provides a set of seawater desalination and reclamation conditioning devices. A seawater desalination water inlet pipeline is connected to a water inlet of a carbon dioxide absorbing tower; a water outlet of the carbon dioxide absorbing tower is connected to a water inlet of a seawater desalination water tank; one end of a main pipeline is connected to a water outlet of the seawater desalination water tank while the other end of the main pipeline is connected to a water inlet of a lime milk pipeline mixer; a seawater desalination water pump and a first online PH meter which is interlocked with a carbon dioxide gas regulating valve are arranged on the main pipeline; an outlet pipeline of the lime milk pipeline mixer is connected to a conditioning water tank, and a second online PH meter which is interlocked with a lime milk adding metering pump is arranged on a connecting pipeline. The whole set of system equipment is controlled by virtue of a PLC (Programmable Logic Controller) or a DCS (Distributed Control System), and is used for supplementing a certain quantity of mineralized materials into desalinated seawater in an accurate adding manner so as to guarantee residents in good health and simultaneously protecting the safe running of water supply networks.

Description

Technical field [0001] The invention is applied to the field of seawater desalination and drinking water, and specifically relates to a set of seawater desalination resources and conditioning devices. Background technique [0002] At present, the shortage of water resources has become one of the important factors restricting the sustainable development of my country's social economy. More than 400 of the 669 cities across the country have insufficient water supply, and 110 of them suffer from severe water shortages. The problem of water shortage is particularly serious in some economically developed coastal cities. At the same time, many coastal cities in my country have a single structure of water resources and are overly dependent on surface water. In recent years, the occurrence of micro-pollution of surface water sources and sudden pollution incidents has caused residents to worry about water supply. [0003] The water intake of desalination is not affected by time and climat...
