Description
Technical field
The utility model relates to water treatment system, specifically a kind of reverse osmosis water treatment system.
Background technology
In known technical field, reverse osmosis system is mainly through carrying out reverse-osmosis treated by membrane element assembly to former water, and the temperature of the working efficiency of membrane element and former water is closely bound up, if former water temp is too low, reverse-osmosis treated efficiency also can decrease, and adds production cost; If former water temp is too high, then can reduce the adaptation life-span of membrane element internal structure, so the temperature of former water preferably remains in certain scope to reach maximum efficiency.Tradition water technology trial lecture pus is all back to raw water box, the discharge waste of the pus avoided like this, but due to the pH value of pus higher, can affect to some extent the pH value of former water, affect reverse-osmosis treated effect.
Utility model content
The purpose of this utility model is to provide the reverse osmosis water treatment system that a kind of structure is simple, can effectively increase work efficiency, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of reverse osmosis water treatment system, comprises former pond, electric heater unit, high-pressure pump, reverse osmosis unit and PLC control unit; Described former pond is connected with the left end of filtration unit by the first valve, the right-hand member of filtration unit by the second valve connection electric heater unit, in addition, filtration unit also while separate connection washing unit; Described electric heater unit, high-pressure pump are connected by pipeline successively with reverse osmosis unit, wherein, RO film is provided with in reverse osmosis unit, and the exit end of reverse osmosis unit port connects pure water pond, temperature-detecting device is provided with between pure water pond and reverse osmosis unit, another port of the exit end of reverse osmosis unit is pus outlet, and connects pus pond and former pond respectively, between former pond and reverse osmosis unit, be provided with reverse flow valve; Between described electric heater unit and temperature-detecting device, independently PLC control unit is set.
As further program of the utility model: the filter membrane in described filtration unit is pocket type ultra-filtration membrane.
As further program of the utility model: described first valve and the second valve are check valve.
Compared with prior art, the utility model structure is simple, working stability, effectively can improve the working efficiency that reverse osmosis attracts; Control electric heater unit by PLC control unit, thus control the working temperature of reverse osmosis unit, can extension device work-ing life.
