Embodiment Construction

[0015] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0016] The filtration accuracy of reverse osmosis membrane (RO membrane) water purification technology is as high as 0.0001 micron, which can filter out almost all impurities and salts except water. However, the negative effect of the high-precision RO membrane is that it is extremely easy to be fouled. In order to prevent the RO membrane from being fouled and ensure the smoothness of the membrane during the water production process of the RO membrane, the RO membrane of the RO pure water machine must be produced while producing pure water. Ensure sufficient raw water to flush the surface of the RO membrane, so a large amount of waste water will be generated. The recommended value of the raw water utilization rate of the RO membrane produced by the famous American Dow Company is 15%. In China, pure water machine manufacturers use more Korean "Sehan m...

Abstract

The invention discloses a strong-pulse micro-wastewater emission and purification system which comprises a water inlet tee joint (1), a front filter group, a booster pump (13), a reverse osmosis membrane filter (15), and a rear active carbon filter (19) which are sequentially connected through a pipeline, wherein an outlet of the rear active carbon filter is connected with a water outlet (20) through a high-pressure switch (18), an outlet of the reverse osmosis membrane filter is connected with a water storage pressure barrel (4) through a pipeline, a wastewater discharge pipeline is arranged at an outlet of the reverse osmosis membrane filter, a pulse electromagnetic valve (14) is arranged on the pipeline, and after the water storage pressure barrel reflows trace pure water to the front end of the reverse osmosis membrane filter (15) through a pipeline and a one-way valve (22) and after the trace pure water is produced, a reverse osmosis membrane is soaked. According to the strong-pulse micro-wastewater emission and purification system, through two measures of rapid instant pulse pollution discharging and washing of the reverse osmosis membrane and pure water reflowing and washing and soaking and protecting of the reverse osmosis membrane, the raw water utilization rate is greatly increased to above 75 percent.

Description

technical field [0001] The invention relates to a water purifier, in particular to a strong pulse micro-wastewater discharge water purification system. Background technique [0002] Most cities in my country use Class III surface water, and rural areas mainly use Class IV groundwater as their drinking water source. With the intensification of pollution, problems such as two insects (Giardia flagella, Cryptosporidium), blue-green algae, and heavy metals exceeding the standard, etc., Serious threat to urban and rural drinking water safety. Therefore, surface water and groundwater must be purified before they can be used as drinking water. At present, the core of domestic and commercial drinking water treatment technology is mainly membrane filtration technology. One of them is ultrafiltration membrane filtration, with a filter pore size of 0.01 microns, which can remove all turbid substances (such as sediment, rust, etc.), pathogenic microorganisms (such as parasites, bacteri...
