Principle of work of the present invention is: can regulate water outlet according to different water quality demands after water enters reverse osmosis membrane 12, after water is pumped into reverse osmosis membrane 12 by lift pump 14, just has two kinds of purification process.
The first technique: when closedown high-quality water flowing water Valve 8, when opening pure water flowing water Valve 9, ultra-filtration water will carry out reverse-osmosis treated, after reverse osmosis, water enters pure water rising pipe 6, the dense water of reverse osmosis membrane 12 is through the 3rd port of reverse osmosis Y-junction 19, mix with the aqueous phase from the beginning entering water inlet pipe 5 after inlet triplet for water joint 18, mixed water delivers to ultra-filtration membrane room B again, achieve the recycle of dense water, water outlet after ultrafiltration and reverse osmosis is not containing bacterium, virus, heavy metal, the pure water of other impurity such as protein and organism, only containing several soluble ions that molecular weight is very little in water, average ratio of desalinization reaches more than 95%.In addition, regulate needle type valve 10 both can control the concentrated stream amount of reverse osmosis membrane 12, the pressure of reverse osmosis membrane can be regulated again.What this spline filter produced is pure water.
The second technique: when opening high-quality water flowing water Valve 8, when closing pure water flowing water Valve 9, water enters uv steriliser 11, after ultraviolet irradiation, bacteriophage residual in water will be killed, simultaneously due to the organism in the luminous energy degradation water of ultraviolet specific wavelength, thus the content of Organic substance in water can be reduced further, water after ultrafiltration and uv sterilisation enters high-quality water rising pipe 7, now do not contain suspended matter in water outlet, colloid, iron rust, silt, algae and bacterium and virus, but the mineral composition in reservation water body existing for self, water outlet reaches operable clean water standard.What this spline filter produced is high-quality water.
Complete assembly structure is simple, easy and simple to handle, and can realize effluent quality and meet state health standards, and water outlet can directly use.Such as, pass through to collect rainfall on slope land in the drinking water source in area, China many mountainous rural areas, after equipment ultrafiltration-uv sterilisation process, effluent quality reaches drinking water sanitary standard GB5749-2006; Equipment is also tested for TAIHU LAKE, after adopting filtration-reverse osmosis process, does not detect the microorganisms such as bacteriophage in water outlet, and physical and chemical index, also far away higher than drinking water sanitary standard GB5749-2006, only contains a small amount of soluble ion in water outlet.In addition, this equipment can life-time service, without the need to more renew cartridge frequently.
Although the present invention with preferred embodiments openly as above; but it is not for limiting claim; any those skilled in the art do not depart from line with invention spirit and scope in; possible amendment and variation can be made; therefore, the scope that protection scope of the present invention should define with the claims in the present invention is as the criterion.
