In recent years, though there is manufacturers to invent RO reverse osmosis water purification machine zero-discharge technology, following problem appearred all in practical process:

1, practicality is not strong, not enough hommization.

As: certain technology is that machine just begins to start system water when opening water tap use domestic water, and the waste water of making water generates this moment becomes the domestic water outflow jointly with the former water of tap water one, realizes the purpose of " no waste water " with this.When water tap was closed, this RO reverse osmosis water purification machine promptly quit work.

The problem that this series products exists is: the water production rate wretched insufficiency can not guarantee normal drinking-water and the diet water of using.Obtain enough pure water if desired and use, then still need the draining of limit system waterside, and meaningless draining promptly means waste water resource.

2, sacrifice the life-span of effluent characteristics and shortening RO reverse osmosis membrane.

Waste water is directly connected to the water-in recycling system water of RO reverse osmosis water purification machine through variety of way; The be far from quality good (the TDS value increases) of former RO reverse osmosis water purification machine of the water outlet that facts have proved this mode; Simultaneously cause constantly increase of soluble solid value (TDS) in the water because of direct circulation, RO reverse osmosis membrane easy blocking has shortened life-span of RO reverse osmosis membrane; Increase use cost, the work-ing life of RO reverse osmosis membrane is shorter in the area, water source of high TDS value.

The utility model content

The purpose of the utility model is that a kind of reliable operation is provided, can makes full use of waste water (waste water), assurance is consistent with the effluent characteristics of former water purification machine, do not damage the reverse osmosis membrane RO reverse osmosis water purification machine sewage recovering system in work-ing life.

For realizing above-mentioned purpose, the technical solution of the utility model is:

The utility model is a kind of RO reverse osmosis water purification machine waste discharge recovery system, and it comprises water purification machine, water pump, wastewater collection container, SV, reverse checkvalve; Described exit of pump is connected with import, the municipal water sources of water purification machine respectively through pipeline, and the import of water pump is connected with municipal water sources, wastewater collection container respectively through pipeline, and the water port of water purification machine is connected with the wastewater collection container through pipeline; One SV is installed on the pipeline that is communicated with exit of pump and water purification machine; One SV and a reverse checkvalve are installed on the pipeline that is communicated with exit of pump and municipal water sources; One SV is installed on the pipeline that is communicated with water pump import and municipal water sources, a reverse checkvalve is installed on the pipeline that is communicated with water pump import and wastewater collection container.

Described wastewater collection container is provided with water monitor.

After adopting such scheme, the utlity model has following advantage:

1, because the utility model comprises water purification machine, water pump, wastewater collection container, SV; Be provided with SV at pump outlet, these SVs are to carry out work according to the water level situation of wastewater collection container, realize the draining and the moisturizing of wastewater collection container, and reliable operation is simple in structure.

The waste water of discharging when 2, the RO reverse osmosis water purification machine is worked is temporarily collected (this container is changeable) with container.The effluent characteristics of pure water can not cause the rising of TDS value because of waste water directly circulates, the RO reverse osmosis membrane stops up the work-ing life that shortens the RO reverse osmosis membrane.

3, waste water is turned back in the source, municipal tap water, when reclaiming waste water, suspend the system water conservancy project of RO reverse osmosis water purification machine and do, to guarantee not influence the technical characteristic of RO reverse osmosis water purification machine.

4, whole process solves to reach hommization with automatic control mode.

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.
