As preferably, the ingress of described reverse osmosis system B is provided with medicine system.When reverse osmosis system B moves as two-pass reverse osmosis, this medicine system can regulate the water inlet pH value that enters reverse osmosis system B, meets the requirement of feed water by reverse osmosis water quality to pH.
As preferably, between described lift pump A and the outlet of lift pump B, by pipeline, be connected, this section of pipeline is provided with the 5th valve.Whether can control like this lift pump B water out needs through cartridge filter.
As preferably, between described lift pump A and the import of lift pump B, by pipeline, be connected, this section of pipeline is provided with the 6th valve.Can control like this water tank A wet concentration out selects and enters lift pump A and lift pump B or enter separately lift pump B.
As preferably, the exit of described pretreatment water tank is provided with the 7th valve.
Therefore, the utility model can reduce water source, exerting oneself changes the impact that reverse osmosis operating load is changed; Frequent start-stop while avoiding series operation.Operation is controlled simple, saves water treatment system investment cost, guarantees reverse osmosis system also steady running when other factors affects, simple and reasonable for structure.
