Problems solved by technology
[0003] The existing ultra-pure water preparation equipment has problems of insufficient purity and low quality standards when used. At the same time, it is difficult to maintain ultra-pure water and freshness for a long time when ultra-pure water is stored. The traditional method cannot guarantee sustained high Ultrapure water with high purity and freshness

The invention relates to an ultrapure water preparation device. The tap water is treated sequentially by means of a filter box, a fine filter, a first reverse osmosis (RO) machine, a second RO machineand an EDI water purifying device, so that high-quality ultrapure water can be obtained; the whole device is simple in preparation raw materials and sophisticated in process operation; a chemical feeding tank is specially arranged, so that the ultrapure water preparation device is suitable for being applied to a pharmaceutical production process; furthermore, the device detects the freshness andpurity of the ultrapure water in a return pipe, communicated with an ultrapure water tank, by means of a conductivity meter, and the return pipe is matched with a reflux pump so as to enable the waterto flow back into a communicating pipe for circulating ultrapure water treatment; chemical feeding treatment can be carried out by means of the chemical feeding tank in the circulating treatment process, so that the water supply quality in the ultrapure water tank is kept fresh and high in purity constantly.
Description
technical field [0001] The invention relates to an ultrapure water preparation device and an ultrapure water preparation method thereof, belonging to the technical field of water treatment. Background technique [0002] In the fields of biology, medicine, electronics, electroplating, etc., a lot of waste water will be generated in production. The water quality varies with the production process, and contains metal ions in the form of cations, cyanide, acid, and alkali. The current water treatment method is RO reverse osmosis membrane treatment method. Its principle is to use a high-pressure water pump to increase the pressure of +-20 kg of raw water, so that the raw water can permeate through the reverse osmosis membrane with a pore size of only 0.0001 micron under the action of pressure. Chemical examples Bacteria, fungi, and virions cannot pass through, although water is not discharged, only water molecules with a volume smaller than 0.0001 microns are allowed to pass thr...
