Description

A direct drinking water purification device

technical field

The utility model relates to a sewage purification device, in particular to a direct drinking water purification device.

Background technique

With the continuous deepening of people's awareness of environmental protection, more and more attention has been paid to the reuse of sewage. Most of the sewage purification devices on the market can only initially filter the water to remove larger impurities and dirt in the water, but there are still a large number of smaller impurities. The water filtered by the purification device can only be used for agricultural water. Or industrial water, cannot be used as direct drinking water.

Contents of the invention

The purpose of the utility model is to provide a direct drinking water purification device, which can solve the deficiencies of the known technology, using three filters of microfilter, ultrafilter and nanofilter to purify the sewage, and can remove impurities and dirt in the water. Get straight drinking water.

In order to achieve the above object, the utility model is achieved through the following technical solutions: a direct drinking water purification device, including a microfilter, a water inlet pipe is installed at the water inlet end of the microfilter, and the water outlet end of the microfilter passes through the first pipeline and the inlet of the ultrafilter. The water end is connected, the water outlet end of the ultrafilter is connected with the water inlet end of the nanofilter through the second pipeline, and an outlet pipe is installed at the water outlet end of the nanofilter.

A third pipeline is installed on the outlet pipe, a second control valve is installed on the third pipeline, the third pipeline is connected with the recoil device, the recoil device communicates with the water outlet of the nanofilter through the fourth pipeline, and the microfilter is installed The sixth pipeline, the third control valve is installed on the sixth pipeline, the sixth pipeline communicates with the membrane bioreactor, the membrane bioreactor communicates with the water inlet pipe through the fifth pipeline, and the fourth control valve is installed on the fifth pipeline.

The utility model has the advantages of: using three filters of microfilter, ultrafilter and nanofilter to purify the sewage, can completely remove impurities and dirt in the water, and obtain clean water for direct drinking. Compared with the existing sewage purification device, the utility model The new type of purification effect can be improved by 500%-600%; it is equipped with a recoil device, which can use the purified water to automatically clean each filter, and the cleaning is simple and fast; the structure is reasonable and the processing efficiency is high.

Description of drawings

Accompanying drawing 1 is the front view structure schematic diagram of the utility model.

Detailed ways

The utility model is further described with reference to the accompanying drawings:

A direct drinking water purification device described in the utility model includes a microfilter 7, the water inlet of the microfilter 7 is installed with a water inlet pipe 6, and the water outlet of the microfilter 7 communicates with the water inlet of the ultrafilter 9 through a first pipeline 8 , the water outlet end of the ultrafilter 9 communicates with the water inlet end of the nanofilter 11 through the second pipeline 10, the water outlet end of the nanofilter 11 is equipped with an outlet pipe 12, and an outlet valve 13 can be installed on the outlet pipe 12.

The utility model is further characterized in that: a third pipeline 15 is installed on the water outlet pipe 12, a second control valve 14 is installed on the third pipeline 15, and the third pipeline 15 is connected with a recoil device 16, and the recoil device 16 can be Devices such as water pumps controlled by computers. The recoil device 16 communicates with the water outlet of the nanofilter 11 through the fourth pipeline 17, the sixth pipeline 3 is installed on the microfilter 7, the third control valve 4 is installed on the sixth pipeline 3, the sixth pipeline 3 is connected to the The membrane bioreactor 1 is in communication, and the membrane bioreactor 1 is in communication with the water inlet pipe 6 through the fifth pipeline 2, and the fourth control valve 5 is installed on the fifth pipeline 2. In this embodiment, the backflushing device 16 can backwash and clean the nanofilter 11, the ultrafilter 9 and the microfilter 7 sequentially with purified water to remove the pollutants trapped in each filter, and the cleaned sewage flows into the membrane In the bioreactor 1, the pollutants are degraded, and the treated water is sent to the water inlet pipe 6, and then filtered through various filters for use.

When the utility model is in use, sewage enters the microfilter 7 through the water inlet pipe 6, and the filter layer in the microfilter 7 intercepts larger particle pollutants to realize preliminary purification; the water after preliminary purification enters the ultrafilter 9, and is filtered by ultrafiltration The micropores on the hollow fiber tube wall in the device 9 trap finer pollutants, and the filtration accuracy of the ultrafilter 9 can reach 0.001-0.02 microns; the water filtered by the ultrafilter 9 enters the nanofilter 11, Utilize the semipermeability and chargeability of the nanofiltration membrane of the nanofilter 11 to intercept nanoscale substances in the sewage, remove organic matter and chroma, etc., and obtain clean water for direct drinking, which flows out through the outlet pipe 12. After the utility model has been used for a period of time, the second control valve 14 and the fourth control valve 5 are opened, and the clean water purified by each filter enters the recoil device 16 through the third pipeline 15, and the recoil device 16 recoils the clean water Flush back to each filter, and finally flow into the membrane bioreactor 1 for degradation treatment. After the sewage treatment is completed, the fourth valve 5 is opened, and the treated water enters the water inlet pipe 6 and is filtered by each filter again to become a direct drinking net. water.
