Accompanying drawing explanation
Fig. 1 is the process flow sheet of two-pass reverse osmosis water treatment system of the present invention.
Embodiment
In the present embodiment, shown in Fig. 1, comprise the pretreatment unit 1, first-stage reverse osmosis device 2, second level reverse osmosis apparatus 3, EDI system and device 4 and the nitrogen-sealed water tank device 5 that connect successively, in this two-pass reverse osmosis water treatment system, be also provided with for controlling the PLC Controlling System (not shown) of pretreatment unit 1, first-stage reverse osmosis device 2, second level reverse osmosis apparatus 3, EDI system and device 4 and nitrogen-sealed water tank device 5; Described pretreatment unit 1 comprises raw water box 10, raw water pump 11, more medium filter 12, activated charcoal filter 13 and the one-level cartridge filter 14 connecting successively, between described activated charcoal filter 13 and one-level cartridge filter 14, is provided with Scale inhibitors chemicals dosing plant 15; Described first-stage reverse osmosis device 2 comprises one-level high-pressure pump 20, first-stage reverse osmosis system 21 and the intermediate water tank 23 connecting successively, and described level one reverse osmosis system 21 sides are provided with cleans water tank 22; Described second level reverse osmosis apparatus 3 comprises secondary cartridge filter 30, secondary high-pressure pump 31, two-stage reverse osmosis system 32 and the pure water tank 34 connecting successively, between described intermediate water tank 23 and secondary cartridge filter 30, is provided with pH value setting device 33; Described EDI system and device 4 comprises EDI topping-up pump 40, ultraviolet sterilizer 41, accurate filter 42 and the EDI system 43 connecting successively.
Its production technique is: operator connects overhead control power supply electricity cabinet at A place, former water enters into raw water box 10 from B, and shock absorption is played in the supply of 10 pairs of former water of raw water box, coordinates the feed rate of former water and the input of raw water pump.When the supply of former water surpasses the carrying capacity of raw water pump, raw water box water is full, by the liquid level of raw water box, is controlled and is used former water supply to stop.When former water supply is less than the carrying capacity of raw water pump, raw water box is empty, and raw water pump is out of service, plays the effect of protection raw water pump.Raw water pump 11 is for former water is pressurizeed, for pretreatment system provides propulsion source.Former water flows to more medium filter 12 places after raw water box 10, and in 12 pairs of former water of more medium filter, the material such as suspended substance, particulate matter and colloid is removed, and reduces turbidity and colourity in former water simultaneously, makes SDI value be not more than 4.Former water flows to activated charcoal filter 13 places after more medium filter 12, and 13 pairs of former water of activated charcoal filter discolor, and removes by formed colourities such as iron, manganese and plant decomposition product or organic pollutants; Dechlorination .0 can remove and smell taste because of what chlorine residue caused; Remove organism and remove micropollutant in the water that common process cannot be removed due to pollution of waterhead, as agricultural chemicals, sterilant, chlorinated hydrocarbon, aromatics, and BOD and COD etc.; Before removal organochlorine is removed in purificating raw water process and tap water dispatches from the factory, add " three cause " materials such as THMS that preoxidation agent and sterilizing agent (as chlorine) are produced.Have to analyze to show, in tap water, " three cause material THMS accounts for most, effectively removes very crucial for the amount of increasing water quality; Remove ammonia nitrogen and nitrite; Remove residual nitrogen or oxygenant, the filter membrane of protection ultrafiltration, reverse osmosis.In addition, it can also deodorizing, removes the micro heavy ion (as mercury, chromium plasma) in water, synthetic detergent and radioactive substance etc.Former water flows to Scale inhibitors chemicals dosing plant 15 places after activated charcoal filter 13, to add Scale inhibitors in former water, meets the water inlet needs of reverse osmosis system.Former water flows to one-level cartridge filter 14 places after Scale inhibitors chemicals dosing plant 15, and one-level cartridge filter 14 is removed suspended substances more than 5 μ m, to protect the first-stage reverse osmosis system membranes can be not blocked.Former water flows to first-stage reverse osmosis system 21 places after one-level cartridge filter 14, and one-level high-pressure pump is the main dynamics equipment of first-stage reverse osmosis equipment.One-level high-pressure pump arranges high overheating protection, and low, high voltage protective switch is set respectively before and after pump.After high-pressure pump intake pressure is lower than set(ting)value, high-pressure pump is stopped transport, and to protect high-pressure pump, after high-pressure pump top hole pressure is higher than set(ting)value, high-pressure pump is stopped transport, to protect reverse osmosis membrane.First-stage reverse osmosis system 21, except most inorganic salt, organism and microorganism etc. in former water, makes specific conductivity at 10 μ
/below cm, reach the standard of pure water; 22 pairs of first-stage reverse osmosis films of cleaning water tank of first-stage reverse osmosis system 21 sides clean, after first-stage reverse osmosis system 21, flow to intermediate water tank 23, after intermediate water tank 23, flow to two-stage reverse osmosis system device 3, in two-stage reverse osmosis system device 3, pass through secondary cartridge filter 30, secondary high-pressure pump 31, pH value setting device 33 and two-stage reverse osmosis system 32, further remove most inorganic salt, organism and microorganism etc. in former water, and regulate pH value, make specific conductivity at 5 μ
/below cm, then flow to pure water tank 34.Water flows to EDI system and device 4 after pure water tank 34, in EDI system and device 4, by EDI topping-up pump 40, ultraviolet sterilizer 41, accurate filter 42 and 43 pairs of water of EDI system, further process, the purity of water is further improved (resistivity >=15M Ω .CM), finally flow into nitrogen-sealed water tank 5, nitrogen-sealed water tank 5 makes electrical conductivity of water constant; Whole like this water treatment completes.
Two-pass reverse osmosis water treatment system of the present invention: because it comprises pretreatment unit, first-stage reverse osmosis device, second level reverse osmosis apparatus and the EDI system and device connecting successively, water is after first-stage reverse osmosis device, second level reverse osmosis apparatus and EDI system and device are processed, electrical conductivity of water, pH value and other parameter can reach the level ultrapure water national standard > > GBT11446 of < < China Electronics secondary standard, and the purity of water is very high.Can not use soda acid, can, to environment, not reach the requirement of environmental protection; In another this two-pass reverse osmosis water treatment system, be also provided with for controlling the PLC Controlling System of pretreatment unit, first-stage reverse osmosis device, second level reverse osmosis apparatus and EDI system and device, simple to operate, productivity improves, and has also reduced cost of labor and production cost simultaneously.
Above-described embodiment, just an example of the present invention, is not for limiting enforcement of the present invention and interest field, all or technical schemes of being equal to identical with content described in the claims in the present invention, all should be included in protection domain of the present invention.
