Embodiment
[0020] A method for improving the efficiency of producing pure water in reverse osmosis mode, comprising the steps of:
[0021] (1) Pretreatment: After the system feed water is filtered by the pre-filter module, it reaches the water quality index of the reverse osmosis feed water, and then it is sent to the raw water tank, which can prolong the chemical cleaning cycle of the reverse osmosis membrane and improve its service life. The water absorbed by the water tank is sent to the water inlet of the second multimedia filter through the raw water pipeline, and a low liquid level protection switch is installed in the raw water tank to protect the raw water pump; the pre-filter assembly includes a manganese sand filter, a first multimedia filter and an activated carbon filter , the order of use is manganese sand filter, first multi-media filter and activated carbon filter;
[0022] Among them, the second multi-media filter needs to be backwashed: the steps are: open the upper disc...

The invention discloses a method for improving the efficiency of producing purified water in a reverse osmosis mode. The method comprises the following steps of pretreatment, wherein system inlet water is filtered through a pre-filtering assembly to meet the inlet water quality indexes of reverse osmosis inlet water and then enters a raw water tank, the water is pumped into a second multi-media filter through a raw water pump, and a low liquid level protection switch is arranged in the raw water tank; reverse osmosis desalination, wherein the water passes through a precise filter, a chemical adding device and a reverse osmosis desalination device; purified water storage and conveying, wherein the water subjected to reverse osmosis desalination is sent to the purified water tank and sequentially passes through an ozone generator, an oxygen generator, a freezing dryer, a terminal water supply pump and a steam-water mixing pump to obtain the purified water. According to the method for improving the efficiency of producing the purified water in the reverse osmosis mode, production adopts the mode of combining a physical method serving as the main method with a chemical method serving as the assisting method, the efficiency is obviously higher than that of a general production method, by means of a backwashing technology of the multi-media filter, redundant parts in the water are removed, and the production efficiency is high.
Description
technical field [0001] The invention relates to the technical field of pure water production, in particular to a method for improving the efficiency of producing pure water in a reverse osmosis mode. Background technique [0002] Purified drinking water is made from water that meets the sanitary standards for drinking water, and is obtained by electrodialysis, ion exchange, reverse osmosis, distillation and other appropriate processing methods, and is sealed in a container without any additives. water that is directly drinkable. As we all know, with the improvement of people's living standards in the past ten years, people's requirements for drinking water are getting higher and higher. The drinking water quality indicators in the standard have been increased from 35 in the original standard to 106 items, among which the organic compound indicators have increased by 48 items, which shows that people attach importance to the safety of drinking water. Pure water that is clea...
