Description
Technical field
The present invention relates to the reverse osmosis water quality processing system of a kind of non-wastewater discharge.
Background technology
Along with the development of modern industry, environmental pollution is on the rise, and " drinking water " problem gradually causes the concern of people.Municipal administration
The secondary pollution problem produced in tap water course of conveying makes Drinking Water water quality treater become the emphasis of people's research, its
In representative be reverse osmosis technology.But the most but frequency shows " automatic water vendor waste water machine ", " water purifier is also
" waste water machine " " report, this is because reverse osmosis membrane carries out advanced treating to tap water produces water purification capable of direct drinking
While, a part " dense water " can be produced, the dense water of this part accounts for about the 70% of former water, i.e. produces 1 ton of water purification, can produce
The dense water of raw 2～3 tons.At present, most reverse osmosis treatment device, the dense water of this part directly drains as waste water,
In today that water resource lacks day by day, this is undoubtedly huge waste.Therefore, how the utilization of dense for this part Water Sproading is become
The focus of people's research.
Traditional reverse osmosis technology, for ensureing the influent quality of reverse osmosis membrane, is generally provided with three grades of pretreatment units, and first
Level is that 5 μm PP cottons are filtered, and can effectively remove the rust in tap water, sandstone, float, colloidal substance etc.；The second level is
Gac filtration, can chlorine residue in active adsorption water, humus, disinfection byproduct (DBP), stink, heterochromatic etc.；The third level
It is that 1 μm PP cotton is filtered, the granule of relatively small particle, float and colloid etc. in water can be removed further.Through this tertiary treatment
After, tap water quality reaches the influent quality requirement of reverse osmosis membrane, can enter reverse osmosis membrane filtration system and carry out advanced treating.
Moisture after reverse osmosis membrane filtration is two parts, and a part has for eliminating major part antibacterial, virus, heavy metal ion etc.
Pest matter, " water purification " that be available for people and directly drink, the electrical conductivity of this partially purifying water is 10 μ about s/cm；Another portion
Being divided into " dense water ", the dense water of this part is because have passed through three grades of pretreatment systems, the colloid contained, rust, float, chlorine residue
Few more a lot of than in tap water Deng pollutant, but owing to have passed through the concentration of reverse osmosis membrane, the heavy metal ion that contains, virus
Higher than the content in tap water Deng material, surveyed electrical conductivity is 1.3～1.5 times of tap water electrical conductivity.Though the dense water of this part
Can not drink, but can be used to do washing, mop floor, the domestic water as people such as flush the toilet uses.Current reverse osmosis water purifier,
Typically only it is furnished with a pure water inlet to drink, without the recycle device of dense water for people, it is necessary to improve to reach dense water
Reuse, water-saving purpose.
For dense Water Sproading Utilizing question, more existing solutions, these solution great majority are to increasing by dense Water Sproading
It is allowed to be again introduced into reverse osmosis membrane on the inlet pipeline of press pump filter, although the discharge capacity of dense water can be reduced, but this certainly will
The influent quality that can cause reverse osmosis membrane is unstable, thus increases the filtration load of reverse osmosis membrane, shortens its service life；Also
Have plenty of and utilize evaporative condenser retracting device, the moisture in dense water is evaporated the water becoming capable of direct drinking, but this exists equipment
The shortcomings such as structure is complicated, operating cost is high.
