Infiltration production water；When liquid level is in middle position, the 11st motor-operated control valve EV18 at reverse osmosis membrane assembly concentrated water end is opened, to middle water
The moisturizing of case 6, there is provided the water source enough to reverse osmosis membrane；When liquid level is in low liquid level, the 8th Electronic control of intermediate water tank 6 is closed
Valve EV15 and high-pressure pump 11, reverse osmosis membrane assembly 7 are stopped.The intermediate water tank is used to provide not to reverse osmosis membrane assembly 7
Disconnected water source, in front end when insufficient water, the concentrated water of counter-infiltration returns to intermediate water tank, so intermediate water tank 6 not only acts as
The effect of interim water, also also function to the effect of a regulating pondage balance., can be with after when reverse osmosis membrane uses one section
By adding reverse osmosis membrane maintaining agent in intermediate water tank, liquid medicine enters the maintenance of the progress film of reverse osmosis membrane assembly 7 by pipeline,
The liquid medicine come out from reverse osmosis membrane assembly 7 so circulates by returning in intermediate regulations water tank, reverse osmosis membrane can be protected
Support.
The production water end (W.E.) of the reverse osmosis membrane assembly 7 is connected with ultraviolet ray disinfector 12, is exported by ultraviolet ray disinfector 12
Pure water, the pure water of output can use water pot storage and direct use to transport to drinking-water point..The ultraviolet ray disinfector 12 by
Electrical control part and fuselage sections composition, fuselage material use food-grade stainless steel, surfaces externally and internally mirror finish, increased ultraviolet
Line reflection rate, water is by being wherein effectively increased bactericidal effect.Because the disinfection by ultraviolet light time is of short duration, product water may have microorganism
Pollution again, be unfavorable for the storage of water, therefore, product water also need to carry out chlorination.The ultraviolet ray disinfector 12 it is defeated
Go out end connection sterilization measuring pump 13, chlorine-containing disinfectant, the sterilization measuring pump and controller are contained in the sterilization measuring pump 13
Electrical connection, for controlling the start and stop of sterilization measuring pump.
The first, second, the five, the six, the seven, the eight, the nine, the ten, the 11st, the tenth described in the utility model
2nd, the 13rd, the 14th, the 15th motor-operated control valve uses magnetic valve.Three, the 4th motor-operated control valve uses electric ball
Valve.
Operation principle of the present utility model：
Controller（PLC）Start water pump 1 first, raw water is pumped into blender 2 by water pump 1, according to first-class
The real time data of gauge collection starts coagulant measuring pump 14, injects flocculant into blender 2 by coagulation measuring pump 14, makes
Flocculant sufficiently mixes with raw water in blender 2, and flocculant reacts with the colloidal substance in water and suspended things, generates bulk
Material；Secondly Multi-stage spiral desander 3 and self-cleaning filter 4 are started, generation granulated substance sequentially enters multistage with water
The first order hydrocyclone of hydrocyclone 3, second level cyclone separator carry out separating treatment, at multistage cyclonic fluid separator 3
Water after reason enters self-cleaning filter 4, and 200 μm of material can be will be greater than by self-cleaning filter 4 and is filtered out, passes through first
The output pressure of pressure gauge detection Multi-stage spiral desander 3, the water after filtering are sent into ultra-filtration membrane device 5 and filtered, and form first
Level separation；Before ultra-filtration membrane device 5 is sent into, the motor-operated control valve of two groups of hyperfiltration membrane assemblies is controlled by controller, makes wherein one
Group hyperfiltration membrane assembly connection, is filtered to the filter water of self-cleaning filter 4, and another group of hyperfiltration membrane assembly is closed, and carries out ultrafiltration
The cleaning of membrane module, so alternate operation, fully ensure that milipore filter has continuously that purified water supplies to intermediate water tank, shape
Separated into the second level.Water after ultra-filtration membrane device filters, which can enter active carbon filter 8, can also be directly entered centre
Water tank 6, normally water processed is without active carbon filter 8, and when the water after purification has peculiar smell or has pigment, opening the 7th is electronic
Control valve EV14, water enter active carbon filter 8 by pipeline, and peculiar smell and pigment are tightly held by activated carbon, into intermediate water tank 6；
The information that controller detects in real time according to liquid level detector, the motor-operated control valve EV15 of high-pressure pump 11 and the 8th is controlled, when middle water
When the water of case reaches high level, start the motor-operated control valve EV15 of high-pressure pump 11 and the 8th, high-pressure pump 11, which is run, gives reverse osmosis membrane group
Part 7 provides press water, and pressure is adjustable from 0.5~1.2MPa, and six reverse osmosis membranes connected by reverse osmosis membrane assembly 7 are carried out
Filter again, form third level separation；When the water level in regulating tank is in middle liquid level, the concentrated water end of reverse osmosis membrane assembly 7 is opened
The 11st motor-operated control valve EV18, to intermediate water tank moisturizing, after reaching high level, close the 11st motor-operated control valve EV18,
The moisturizing no longer into intermediate water tank, is so repeated, until the machine of closing down.Finally start ultraviolet ray disinfector 12 and malicious measuring pump
13, the good water after the purification of reverse osmosis membrane assembly 7 is flowed into by the second conductometric detector and ultraviolet ray disinfector 12, passes through ultraviolet
After sterilizer 12 carries out ultraviolet disinfection, then chlorine-containing disinfectant sterilization is carried out, ensure that purified water meets national water hygiene mark
It is accurate.
