Abstract
The invention discloses a reverse osmosis (RO) water quality treatment system without waste water emission, which includes: a tap water inlet, a three-directional conversion valve, a first filter apparatus group, a pressurizing pump, a second filter apparatus group, a purified water storage container, a concentrated water storage container, a double-channel valve, a purified water tap and a concentrated water tap. According to the invention, on the premise of not increasing the filtering load and the energy consumption of a reverse osmosis membrane, the concentrated water generated in the RO filtering system can be directly recycled as domestic water, wherein the system is free of waste water discharge. In the system, by means of the double-channel valve, the concentrated water is used firstly and then the tap water is used, so that the generated concentrated water from the system can be used after being produced instantly and is not stored for a long time. According to the ratio of the concentrated water to the purified water, the purified water storage container and the concentrated water storage container are disposed, wherein the storage volume of the concentrated water storage container is larger than that of the purified water storage container, thereby ensuring that the usage of the purified water is free of being influenced by the storage amount of the concentrated water. By means of a one-way flowing valve at the outlet of the double-channel valve, the concentrated water and the purified water are guaranteed not to be mixed.
Description
Technical field
The present invention relates to a kind of reverse osmosis water quality treatment system of non-wastewater discharge.
Background technology
Along with the development of modern industry, environmental pollution is on the rise, and " drinking water " problem causes the concern of people gradually.The secondary pollution problem produced in the course of conveying of municipal tap water makes Drinking Water water quality treater become the emphasis of people's research, and wherein representative is reverse osmosis technology.But but frequently show the report of " automatic water vendor---waste water machine ", " water purifier is also " waste water machine " " recently, this is because reverse osmosis membrane carries out while advanced treatment produces water purification capable of direct drinking to tap water, a part " dense water " can be produced, this part dense water accounts for about 70% of former water, namely produce 1 ton of water purification, the dense water of 2 ~ 3 tons can be produced.At present, most reverse osmosis treatment device, this part dense water is directly drained as waste water, in today that water resources lacks day by day, this waste huge beyond doubt.Therefore, how this part dense Water Sproading is utilized the focus becoming people's research.
Traditional reverse osmosis technology, for ensureing the influent quality of reverse osmosis membrane, is generally all provided with three grades of pretreatment units, and the first step is that 5 μm of PP cottons are filtered, and effectively can remove the iron rust, sandstone, suspended substance, colloidalmaterial etc. in tap water; The second stage is gac filtration, can chlorine residue in active adsorption water, soil ulmin, disinfection byproduct (DBP), stink, heterochromatic etc.; The third stage is that 1 μm of PP cotton is filtered, and can remove further in water compared with the particle of small particle size, suspended substance and colloid etc.After this tertiary treatment, tap water quality reaches the influent quality requirement of reverse osmosis membrane, can enter reverse osmosis membrane filtration system and carry out advanced treatment.Moisture after reverse osmosis membrane filtration is two portions, a part for eliminate the objectionable impuritiess such as most of bacterium, virus, heavy metal ion, " water purification " that directly can drink for people, this part clean electrical conductivity of water is 10 μ about s/cm; Another part is " dense water ", this part dense water is because have passed through three grades of pretreatment systems, the pollutent such as the colloid contained, iron rust, suspended substance, chlorine residue is than few a lot of in tap water, but owing to have passed through the concentrated of reverse osmosis membrane, the materials such as the heavy metal ion contained, virus are higher than the content in tap water, survey 1.3 ~ 1.5 times that specific conductivity is tap water specific conductivity.Though this part dense water can not be drunk, the domestic water that can be used to do washing, mop floor, flush the toilet etc. as people uses.Current reverse osmosis water purifier, is generally only furnished with a pure water inlet and drinks for people, without the recycle device of dense water, must carry out improving to reach NF concentrated water reuse, water-saving object.
For dense Water Sproading Utilizing question, more existing solutions, these solution great majority filter dense Water Sproading to the suction culvert of topping-up pump makes it again to enter reverse osmosis membrane, although the quantity discharged of dense water can be reduced, but this will certainly cause the influent quality of reverse osmosis membrane unstable, thus increase the filtration load of reverse osmosis membrane, shorten its work-ing life; Also have plenty of and utilize evaporative condenser retrieving arrangement, the moisture evaporation in dense water is become water capable of direct drinking, but there is the shortcoming such as device structure complexity, running cost height in this.
